Couplings for Oil and Gas




For over 50 years Metastream couplings have been operating successfully in the oil and gas industryto ensure plants operate at their optimum performance. The first choice of the majority of the world’senergy suppliers, constant innovations in the design and supply of Metastream couplings ensure thatchanging demands are met and fully comply with API specifications.

Global Support

As a truly global coupling supplier, John Crane is able

to offer unparalleled customer service and technical

support from the design stage to commissioning and

inventory management over the lifetime of the plant.

Operating from over 200 facilities worldwide in over 50

countries, John Crane offers specialised local support forinstallation, shaft alignment and troubleshooting.

Upstream Installations, Extraction,Pipelines and Gas Transmission

Whether you are operating in the cold of Alaska or

Siberia, the dusty heat of the Middle East, the corrosive

environment of the North Sea or in areas of high humidity,

Metastream couplings are designed to meet your needs,

safely and reliably. Metastream couplings provide

solutions for both land based and offshore extraction in

all areas such as gas compressors, crude oil, sea water

injection, diesel and potable water pumps. For liquid and

gas pipelines, especially remote stations where absolute

reliability and safety are of paramount importance,

Metastream can be relied on to give exceptional

performance.

From Design Stage Throughto Plant Management

Downstream Installations

John Crane offers a complete range of couplings for all

refinery applications, from the pumps and steam turbines

on crude distillation units to gas compressors and onto the

various final product plants and storage facilities.

Although the range of duties and sizes of couplingscan be varied, modular design of both the T&M Series

ensures standardisation and keeps spares to an absolute

minimum. This is aided by various software programmes

designed and developed by John Crane’s team of in-house

software engineers.

For less critical areas, the Metastream range of industrial

membrane and Powerstream elastomeric couplings meet

the total requirements of any site.

Training

Training programmes combining theoretical aspects

of coupling technology with hands on installation and

alignment maintenance are available either on your site

or at a John Crane training facility.




Metastream T & M Series CouplingsM Series Range of Couplings

The ultimate in plant safety as loads due to misalignment

and overhung masses are low, ensuring resultant loads

on machinery bearings are minimised so extending life

and reliability. Should extreme overload or excessive

misalignment occur, M Series coupling will safely

disconnect the drive while alerting the plant operator.

• Factory assembled membrane units ensu

T Series Range of Couplings

The T Series scalloped membrane design offers

outstanding ability to accept shaft misalignment with low

imposed forces on equipment bearings.

Unique modular design allows the correctly rated coupling

to be selected even on large shaft equipment, thus

removing the need to supply oversized couplings.

The main drive bolts are fitted with overload collars toprevent membrane rupture in the event of severe torsional

overload.

The spacer is retained by specially designed anti-fly guard

rings to ensure safe operation, even in the unlikely event of

membrane and bolt failure.

Couplings with Long Distance BetweenShaft Ends (DBSE)

Both T & M Series couplings can be supplied with long

spacers in steel or composites for both horizontal and

vertical applications. The M Series, manufactured in

stainless steel with a composite spacer is particularly

suited for use on force draught cooling fans.

Short DBSE Couplings

T Series couplings can be supplied for short DBSE as small

as 3 mm, replacing maintenance intensive gear couplings.

Spark Resistant Couplings

Hazardous areas in renery operations require spark

resistant couplings. This is achieved by replacing the

membrane unit on the M Series and the overload collars

on the T Series with components manufactured from non

ferrous metals.

Axial Adjustment Shims

Where coupling hubs are fitted onto taper shafts, axial

adjustment shims can be incorporated. As the position of

the hubs cannot be accurately set on the shaft, shims are

supplied so the correct length of the transmission unit can

be easily achieved.

Electrically Insulated CouplingsTo stop electrical currents damaging bearings when electric

motors are connected to generators or have equipment

connected at each end, electrical insulation is incorporated

in one hub. This allows standard transmission units to be

used, so reducing spares inventory.

Standard Options for Metastream Coupling

The modular design of the both T & M Series couplings allow several options and additions to thestandard ranges without impacting on leadtimes. It also ensures that spares requirements are kept toa minimum.

High Performance Couplings

World leading turbomachinery manufacturers and users specify Metastream H Series as their rst choice,

with optimised power transmission capabilities allied to minimal weight and reduced moment designs.

L Series Couplings

Metastream L Series general purpose all metal membrane couplings are ideal for critical industrial

applications where a reliable maintenance free solution is required.
