FOR ONSHORE AND OFFSHORE PROJECTS

Carpenteria Meccanica Luigi Rota produces and distributes high quality monol ithic insulating joints for

the oil&gas industry. Wherever you find pipeline and gas distribution systems you will also find a widearray of our products.

When our monolithic insulating joints are used in the right application, savings in the overall costs of

the entire corrosion control system are granted.

FOR ONSHORE PROJECTS

Limiting the spread and hence the cost of cathodic protection to those pipes that need to be effectivelyand economically protected by the main cathodic protection system.

Electrically dividing long pipelines into distinctive cathodic protection system.

Isolating a pipeline and ensuring that cathodic protection or stray electricity currents do not causeincreased corrosion.

Providing protection against earthing currents at domestic and industr ial premises where the PME system

is in use.

FOR OFFSHORE PROJECTS

Isolating the pipeline cathodic protection system in riser pipes and offshore structures.

At field tie-ins.

DEMANGING APPLICATIONS

Making dependable isolation joints with dependable seals for safety-critical and extreme applicationsgoes beyond excellence in design and manufacturing.

It also means a strong commitment to quality.

Carpenteria Meccanica Luigi Rota as a major isolation joints manufacturer, has access to substantial

application data and a wealth of experience. Our practical know-how in using very complex and secure

methods is supported by finite element analysis to combine experience and technology at the same time.

The most extreme environments demand a strong commitment in finding the best sealing solution.Carpenteria Meccanica Luigi Rota is committed in achieving its objectives in very demanding services

for high pressure or hard vacuum applications as well as against corrosive chemical and very low

temperature in-line services.

MATERIAL STANDARDS

Ferrous materials : ASTM, API, UNI, ANSI, DIN, BS, ASME, MSS, NACEFor dielectric non ferrous materials : ASTM, CEI.

For resinous materials, paints & sand-blasting : ASTM, SPPC, ISO, SIS, BS.

RLThanks to the reliability of our insulating joints, with regards to the anti-corr osion

protection of buried pipelines, Carpenteria Meccanica Luigi Rota ensures the safestand most economical operation of pipelines and distribution networks for gas, waterand other hydrocarbons owing to:

the very high reliability of its products; the special manufacturing accuracy; the severe and continuous quality controls implemented in the manufacturing process the original and new designs as illustrated in Fig.1and Fig.4

The S-TYPE JOINTS (Fig. 1) are manufactured for pressures and diameters inaccordance with table A and section 1,2,3, and 4 (Fig. 2), respecting (Fig. 3).

MONOLITIC INSULATING JOINT for MAINLINESMATERIALS

Pipe sections Carbon steel pipes in according to API 5L and ASTM, UNI , DIN and BS

Rolled plates,relevant to the above mentioned specifications longitudinally arc welded (SAW)

Joint body Welded construction out of rings from heavy thickness rolled plates Laminated or forged rings, in accordance with UNI , ASTM and DIN

Insulating materials From epoxy-glass laminates or epoxy glass prefabrications in accordance with ASTM

From polycarbonates From cold-cured epoxy resins

Sealing gaskets From nitril e, fluor ide and silicone elastomers in accordance with ASTM

Coatings Interna l surface : epoxy resins (fusion bonded epoxy) External surface: epoxy primers epoxy paints or specia l high build coatings

WELDING AND NON DESTRUCTIVE TESTING

The metal components that make up the so-called standard joints are joined together by meansof fillet welds if requested, the fillet weld seam may be checked by non destructive tests usingdye penetrants and magnetoscopic inspections.

With different preparation butt welds can be used. In this case, inspect ions by x-rays andultrasounds can be carried out.

All welding processes are in accordance with ASME VIII and IX and are certif ied by independent andInternational Authorities.

TESTS

Sample joint testing or individual joint testing are carried out to guarantee the following minimal values: Hydrostatic test pressure: 1.5 times PN. Dielectric tests (in air and on dry joints) * Electr ical resistance: 5 megohms minimum; tension: 1 kV d.c.

* Resistance to appl ied tension (without discharge): 3 kV / 50 Hz for 1minute

Upon request CARPENTERIA ROTA may supply insulating joints which have been subjected to thefollowing supplementary tests:

Electr ical resistance, when joints are filled with water

L* p = water resistance (ohm x cm) R = p ------ where L* = length of lined internal wall (cm) S S = sectional flow area (sq.cm)

Cyclic hydraulic tests Hydrostatic tests with welded and plates Air-tightening tests Dielectric tests after immersion in 3% NaCI solut ion

*Additional tests are performed according to costomers requirements and/or specifications.
