ET 4.1

Piping and coupling element protected with

PTFE, PFA and FEP are used in all

environments which require high corrosion

protection against mighty aggressive

chemicals at high temperatures,

physiologically neutral lining and non-

adhesive properties of such lining. In the

conditions of rapid temperature changes,

where ceramics, enamel and glass fail, the

fluoride artificial substances proved

indispensable. Elevated hardness of the basiccarrying material combined with excellent

properties of fluoride elements PTFE, PFA

and FEP, and applied according to the shape

of the carrying element and operating

conditions, yield best possible solutions.

Such protection ensures long life, simple

installation and considerably reduces the

maintenance costs.

FEATURES

- practically absolute resistance to

chemicals,

- high temperature resistance,

- PTFE 260 °C,

- PFA 260 °C,

- FEP 200 °C,

- good anti-adhesive properties,

- absolute resistance to atmosphere and

wear,

- physiologically neutral,- very good insulation capacity,

(electric and thermal),

- resistance to impacts,

- low maintenance costs,

- long life.

PTFE dip-pipes are constructed to withstand highmechanical stresses which arise from media mixing in

process vessels and reactors. They are designed to providehigh corrosion protection against highly corrosive

chemicals, high temperatures and requires the presence of

anti-adhesive properties lining. Their usage is

recommended in area of high temperature and need of

anti-adhesive lining.

The steel core of the

dip pipe is protected with

external and internal PTFE

antistatic tube. The ends of

tubes are welded together

with a special procedure.

PTFE, PFA FLEXIBLE PIPES

Metal flexible pipes have been on the market for quite a while. They are

made of high-quality stainless steel and special alloys. They are intendedfor use in conditions with strict demands in order to assure flexible and

absolute tight connection between the joints.

Due to the needs in the chemical and food industry we have developed

PTFE and PFA flexible pipes for aggressive agents decantation.

They can be used anywhere where high pressure is combined with high

chemical aggressiveness, high temperature, occasional moving, static and

dynamic bending, vibrations etc.

The pipe diameter can be between DN 15 and DN 65.

Thermal area of use:

Without outer braiding, outer stainless braiding - 40 do 260 °C

Outer polymer braiding - 40 do 90 °C

Outer rubber braiding - 40 do 100 °C

1. Stainless flange

They can be used for all media to which

stainless steel is chemically resistant, such as

concentrated sulphuric acid, alkalis etc. they aremostly used in food industry, since they meet all

the conditions (up to 260°C).

2. ETFE-protected flange

Pipes are resistant in most inorganic andorganic bases and acids, depending on the

media concentration it is resistant up to 160

°C. ETFE coating is highly resistant to

abrasion, mechanical impacts and ageing.






3. PFA- and FEP- protected flange

Pipes protected with PFA coatings are

resistant to 260 °C, whereas FEP coatings up

to 150 °C in diluted and concentrated organic

and inorganic acids, alkalis, organic solvents

etc. coating thickness is approximately 3 mm.

therefore it is resistant to abrasion.

EXAMPLES OF FLEXIBLE PTFE AND PFA PIPES ASSEMBLY

WRONG RIGHT

Example 1

Pipe is bended to close

to the implement.

Hose is sufficiently long to

form a natural curve.

Example 2

Pipe is to deformed, sootto close to the implement.

Use of elbow fittingdisables the pipe

deformation.

Example 3

Pipe is to deformed, soot

to close to the implement

Use of elbow fitting

disables the pipe

deformation.

Example 4

Pipe bending radius not

sufficient at hanging.

Use appropriate device with

larger radius.

Example 5

Cyclic loading to large,

bending radius at

implement not sufficient.

Pipe loading can be

improved by using two

elbow fittings..

BUTTERFLY VALVE DISC COATING

DIMENSIONS UP TO DN 250

Butterfly valve discs, protected with PFA C antistatic coating are a novelty in our production

programme. The coating is applied on metal parts with the traditional spattering process in the

transfer-moulding models. We have designed new disc form with the following outstanding

characteristics to the steel disc:

• Coating thickness up to 4 mm. • Electric conductivity 14 Ω/cm – useful in EX areas.

• Working temperature up to 260°C. • Stability in diluted and concentrated organic and inorganic acids,

alkalis and salt solutions, organic solvents, halogens and ozones.

• Shiny flat surface.

• Compared to the ETFE, it achieves substantially better resistance to

abrasion and bruising.

• Better sealing and longer disc lasting.

PTFE PISTON RINGS





BO 2.1

PTFE PISTON RINGS

In chemical, food and oil proccesingindustries a large number of nonlubricated

compressors, pumps and other devices

needing materials with good sliding and

sealing properties are being used. As an ideal

one showed the PTFE filled with fillers as

graphite, coal, coke, glass or molybdic

sulphide. By using the filled PTFE a dry

(nonlubricated) operation, economy of

lubricants and elemination of the “stick-

sleep” effect can be achived.

FILDS OF APPLICATION:COMPRESSORS AND

NONLUBRICATED COMPRESSORS

- Seling and guide rings for pressures

up to 220x105 Pa as well as radial and

tangential rings for sealing of piston

rods.

PUMPS FOR LIQUEFIED GASES

- Radial and tangential rings for axles

and sealing bushes

FORMS OF THE CONTACT

SURFACES AT THE SEALING

PISTONS RINGS

Owerlap Contact

With this technically the most exacting

contact form a maximum sealing effect can

be achived. The sealing degree remains

constant during the operation the dilatation,

hitch is a function of

temperature, has noinfluence on it. This

technically idel solutions

is recommendable for

those ompressors whose

pressure difference does not exceed 50x105

Pa.

Moderate Slope Contact

This contact form is

recomenmendable in

cases when extension springs are being used.This kind of sealing is needed for liquefied

gas compressors.

EXPANSIONS MACHINES

- Sealing elements and guide piston

rings as well as tangential and radial

rings.

PNEUMATIC AND HYDRAULIC

CYLINDERS

- Piston rod quides and seals.

Particularly there is a “stick-sleep” effectnoticeable and unwanted. The effect can be

eliminated by using the PTFE elements. As a

result the operatinon becomes precise and

regular. A wide range possibility of

application on the machines mentioned

above has some boundary values which

should be considered at constructions and

transformations:

- The average piston speed at compressors

must not exceed 4,5 m/s.

- The average piston speed at hydraulic and

pneumatic cylinders must not exceed 5 m/s.

- The working temperature depends on

pressure, ist maximal value is 460 K

( 187 °C).

- Pressures above 200x105 Pa

Slope Contact

Is being used for extremely high pressures up

to and over 200x105 Pa and for differences in

pressure above 50x10

5

Pa. The prerequisitefor a reliable

operation of the

machine is an exactly

evaluated working

temperature and a

precise calculation of dilatation.

Orthogonal Contact

The same usage as slope contact.

PTFE WITH FILLERS

With the help of filers the field of application

for PTFE is being strongly increased. The fillersinfluence the following properties of PTFE:

- Pressure resistance is increased 5-10 times.

- Wear resistance is increased up to 1000 times.

- Linear thermal expansion coefficient is reduced

by 80%.

- Heat conductivity can be increased with some

fillers 5 times.

- Hardness is increased by 10-15%

- Specified resistance is reduced.

The addition of fillers causes mainly a

reduction of tensile strength and breaking

elongation. The fillers do not reduce its

temperature resistance, whereas the chemical

resistance depends on the kind of filler.

The following fillers are mostly used:

glass, coal, graphite, bronze, steel, molybdic

sulphide.

FILLER PROPERTIES OF THE

FILLED PTFE

GLASS Pressure and wear resistance,

good chemical resistance.

CERAMICS Better chemical resistance withrespect to the PTFE filled with

glass.

COAL The most inert PTFE, especialy in

alkalies.

COAL, COKE Wear and pressure resistance,

good heat conductivity.

GRAPHITE Good heat conductivity, good

sliding properties.

STEEL 18/8CrNi Small deformation under

pressure.

MoS2 Very good sliding properties, wear

resistance.

BRONZE Very good sliding properties,wear resistance.

WEAR

When loading a sample of a pure PTFE

(without fillers) as it slides upon a perlit casting at

2 m/s with 1 N/mm2, an abrasion of 4 mm has

been found out as early after 6 hours.

The measurements of PTFE with fillers, on the

same testing conditions have shown only after 100

hours the following abrasions:

PTFE with graphite 3,25 mm abrasion

PTFE with glass 0,3 mm abrasion

PTFE with bronze 0,02 mm abrasion

CHEMICAL RESISTANCE

Chemical resistance of PTFE with fillers

decreases under the influence of very aggressive

media. E.G.:

- In Oleum at 423K (150 °C) in 1000 hours: by

0.3-0.7 %, that filled with coal and graphite by 5-7

%.

- In chromic acid at 423K (150°C) in 1000 hours:

the weight of PTFE filled with glass, coal,graphite increases 0,3-0,8 %.

-In fuming nitric acid and aqua regia at 373 K

(100 °C) in 1000 hours: the weight of PTFE filled

with glass, coal, graphite decreases by up to 1 %.

- In 50% KOH at the room temperature in 1000

houres: PTFE filled with coal, graphite shows no

changes whereas thw weight of PTFE filled with

glass decreases by 0.1 %.

HEAT EXCHANGERS





SHELL-AND-TUBE HEAT

EXCHANGERS

The shell-and-tube heat exchanger is

made out of number of parallel pipes that are

closed in a cylindrical casing. The heat

transfer is established when there is a

temperature difference between a warm and a

cold fluid's stream. This model of a heat

exchanger can be used in the same way as

those exchangers made out of other materials,

e.g. metal. But this model holds a very special

place in those production processes, where

problems with corrosion occur (such as

chemical, pharmaceutical, food industry) and where demands after chemically

resistant materials exist; PTFE is one of them for sure. We install them in systems

among the pipelines.

The core of the exchanger is made out of PTFE head and bunch of PTFE pipes.

Supporting construction is made out of steel.

According to the need we can

protect the supporting construction

with ETFE on the inside as well as

on the outside, or we can add the

PTFE coat on the inside.A strong medium's stream on

the both sides of the exchanger is

aimed at the segments that enable a

high exchange proportion. They can

be used in the systems with either

different or same media: gas/gas,

gas/liquid, liquid/liquid.

Exchangers can be used for heating





as well as for cooling. Number and diameters of the pipes are determined on the basis

of the characteristics of the product’s need to be either warmed or cooled.

ETFE POWDER COATING






PN 1.1

ETFE is a thermoplastic copolymer derived from the

polymerization of Ethylene and Tetrafluoroethylenemonomers. This resin is extremely tough and abrasion

resistant, and has excellent chemical resistance,

dielectric strength, and a low coefficient of friction.

USAGE

ETFE fluoropolymer resin is a proven performer in the

chemical and petrochemical processing industries. It

has gained notable recognition for its unique properties

and design versatility, which are helping solve some of

the industry’s toughest material problems in process equipment and components. ETFE provides

excellent resistance to attack by the chemicals and solvents that can cause rapid deterioration of

other plastics and all but the most costly metal alloys. ETFE is inert to strong mineral acids,

inorganic bases, halogens, and metal salt solutions.

ETFE COATING

The most common method is electrostatic application,

using high voltage of 30-100 kV of negative polarity,

which causes large number of electrons to adhere to the

ETFE coating particles on their way through the

electrostatic gun. This creates an electric field between

the gun and the piece of metal and as a consequence powder particles adhere to the opposite side of the

object.

In addition to its chemical resistance, ETFE has

excellent mechanical strength, stiffness, and abrasion

resistance. This may be an important consideration for process applications where abrasive

slurries accelerate wear and degradation of alternative materials. ETFE has a broad continuous-

use temperature range from -150º F to 300º F (-100º C to 180 ºC). Specific temperature ratings

vary depending on equipment design and chemical environment, thus it is important to consult

with component manufacturers for in-use service recommendations.

COATING WITH RUBBER – ELASTOMER FILMGENERAL INFORMATION

Purpose

The purpose of coating with different elastomer films is protection of components against

aggressive agents. The materials usually being protected are:

• construction steel

• concrete and reinforced concrete

We carry out rubber coatings.

Fundamental principleThe system of coating the metal basis

main coating

conducting layer

concrete basis





Basis

The construction of the supporting element needs to be correctly manufactured and to meet

standards, determined by the branch. Furthermore, it needs to respond to the following demands:

• metal components DIN 28051

• surface and weld beam processing DIN 28053

• concrete and reinforced concrete components

Contact surfaces preparation

Basis surfaces need to be cleaned and harsh enough: metals by abrasive blasting according to the

Sa 3 Swedish standard. Surface harshness is 50 µm.

Conducting layer

Conducting layer is built on the concrete and reinforced concrete components in order to ensure

electric conductivity for carrying out the elastomer (rubber) sealing control.Main coating

The purpose of applying main coating is to ensure the best quality adhesion of next layers and

protection against corrosion.

Adhesive

The adhesive is chosen according to the loading and the kind of the elastomer (rubber) used.

Elastomer mixtures (rubber films)

The film thickness is connected to the durability. 2 to 10 mm thick films are used. The price

depends on the thickness; therefore it is important to dimension the thickness correctly according

to the expecting loading.

The table below shows some of the basic rubber film mixtures, their physical properties,

resistance and the way of vulcanising.

VF0111-NR/SBR, graphite – the mixture is appropriate for vulcanising in autoclave, for drinking

water equipment rubber coating. It has all the necessary certificates for it.VF0113-NR/SBR, graphite - the mixture is appropriate for vulcanising in autoclave, for

chemical and process industry equipment rubber coating. It offers resistance to acids and alkali up

to 100˚C.

VF0114- NR/SBR, graphite - the mixture is appropriate for vulcanising in autoclave and with

hot water, therefore it is used for installing on the field where needed. It is used for chemical and

process industry equipment rubber coating, especially for steel tank and pool rubber coating. It

has high resistance to HCl and other acids.

VF0115-IIR - the mixture is appropriate for vulcanising in autoclave. It is used for rubber coating

of galvanic tanks for chromium plating.

VF0116-CR – self-vulcanising mixture with good resistance to abrasion. It can also be vulcanised

in autoclave. It is used for steel and concrete tank rubber coating on field and process equipment

rubber coating where there is greater abrasion, such as sand mills, pipelines for sand transport,

spiratrons, different cyclones etc.

VF0118-BIIR – soft rubber, used for vulcanising in autoclave. It offers great resistance to alkali

and acids up to the temperature of 100˚C. It is used for process equipment rubber coating, such as

pipelines, stirrers, etc.

VF0119-BIIR+CR, adhesive coat – two-coated mixture. The upper coating had already been

vulcanised, whereas the lower is not vulcanised serving as better adhesion for steel, rubber or

concrete. The mixture is used for repairing rubber coating damages.

Hints for choosing a rubber filmChoosing a rubber film is professionally demanding task. It depends on the necessary

characteristics which the film should have in order to meet the needs and purpose of use. The

characteristics depend on the loading to which the coating is about to be exposed during its use.

There are three main types of loading, influencing the choice:

- mechanical loading

- chemical loading

- thermal loading

In order to include more data, we have enclosed a questionnaire to the catalogue. Accurate and

correct information enables quality choice of materials and of the technologic procedure itself. We

recommend that an expert makes the choice.

VulcanisingMost rubber films need to be thermally processed. Autoclaves are used for that because they

ensure the accurate temperature input into the rubber. The similar effect is achieved by using

steam or hot water. After vulcanising, the rubber has the characteristics from the table.

Rubber coating quality control

The following quality controls are exerted during the process:

• conductivity measuring which reveals possible porosity

• hardness measuring

• thickness measuring





WORK IN THE WORKSHOP

The products can be coated with hard or soft rubber film. They are vulcanised inautoclaves where the rubber foil gains the chemical and physical characteristics.

The size of the products to be vulcanised depends on the autoclave dimension:

Large autoclave: diameter 3300 mm, length 10000 mm

Small autoclave: diameter 2300 mm, length 5500 mm





PRODUCTS, RUBBER-COATED IN THE WORKSHOP

Rubber hose Process equipment Rubber tank cover

Rubber-coated mixer Ion exchanger Decomposition tower cover

Centrifuge Orifice plate Fundabac filter

Sand mill wheels Rubber-coated cross part Coating control





FIELD WORK

The rubber coating can be made on field, just like in a workshop. It can be applied on

metal or concrete surfaces. Self-vulcanising mixtures are used at work or mixtures vulcanised by

hot water.
