Utility, Industrial, Refinery and Petrochemical Experience


FlexEJ’s products and services find applications in a wide variety of industries where quality and long term reliable operation are demanded. We are very familiar with meeting complex requirements for documentation, in process NDT and test on projects. We have supplied many large end users such as EDF, Exxon, Shell, Reliance & QatarGas working with major contractors such as JGC, Foster Wheeler & Technip.

Our engineering and applications expertise allows us to meet your needs through selection or design of the most appropriate product.

Water

Desalination and Water Distribution


We have extensive experience in the desalination and water distribution industries from very large sea water intake joints though to small HVAC joints at point of use.

FlexEJ’s sister company Safetech designs and manufactures rubber expansion joints in any diameter to over 3600mm. These are also available in a similarly wide range of rubber compounds to suit the application. Single-, Double-, Triple- or Quad-Arched, we can design in-house to your exact specifications.

Potable water applications are extensively catered for with both rubber and metal expansion joints. Our Elaflex high quality configurable rubber expansion joints have two ranges with WRAS type approval; Safetech manufactures with WRAS approved EPDM and WRAS approved high temperature EPDM. Our copper end metal expansion joints also have WRAS approval and we have DWI accreditation for our large metal expansion joints.

Whatever your needs in desalination and potable water distribution FlexEJ has the experience and breadth of product to help.

The Bellows Finder and Flange Finder resources will help you narrow the search for a suitable product.

Power

Power and Desulphurisation


Power and desulphurisation applications can be very demanding with hot, aggressive and sometimes abrasive media.

FlexEJ has developed temperature modelling for expansion joint design which enables us to predict the material temperature at key points from the media stream out to the external hardware. This allows cost effective designs to be created based on material operating temperatures.

Safetech manufactures large rubber expansion joints using VITON which is suited to desulphurisation applications and FlexEJ also offers the Elaflex VITEX range for applications up to DN200.

FlexEJ has designed and delivered very complex pressure balanced / gimbal / hinged see FAQ metal expansion joints working around 21 Barg / 540°C using high alloy bellows and CrMo piping. Our design and manufacture capability is a key asset in this market.

We also offer much simpler, configurable metal bellows for industrial steam applications - see our Industrial Metal range.

Process

Industrial, Refinery and Petrochemical


FlexEJ has its history rooted in industrial piping systems; the design and manufacture of metal expansion joints is what we do. We design to EJMA, B31.3 / Appendix X, EN14917 and the PED together with associated end user or project specifications.

We also have an extensive range of configurable industrial metal expansion joints all with EJMA calculated bellows available in length to order and materials / flanges of your choice.

Safetech manufactures large rubber expansion joints for cooling water systems - typically EPDM for sea water intake / cooling and Nitrile for closed circuit systems where hydrocarbon contamination may be present.

The Elaflex high quality rubber bellows range is also very well suited to process applications with a choice of Nitrile, Chloroprene and FKM rubbers.

FlexEJ's metal hose assemblies are available to order in materials well suited to process applications including 321, 316, 625 and Monel.

Marine

Offshore and Marine


The Elaflex range of rubber bellows have type approvals from Lloyds Register of Shipping, Bureau Veritas, Det Norsk Veritas, American Bureau of Shipping and TUV. Within the range there are types specifically designed for applications in critical offshore and marine applications such as engine room oils / fuels, high temperature engine cooling water and drilling muds.

The YellowSteel and YellowSteel HNBR bellows are ISO 15540 fire rated 800°C for 30min and the full range range is available with SAE flanges and covers for additional fire protection.

We also design and manufacture metal expansion joints which are used in offshore and marine applications including hydrocarbon lines, flare lines, diesel engine exhaust and gas turbine exhaust. We have also supplied expansion joints for offshore structures.

Frequently Asked Questions


Q. Where should expansion joints or bellows be used?
A. There are three broad applications which may exist in any combination:

> to reduce vibration or noise being transmitted through the piping
> to allow for installation misalignment in the piping
> to allow piping to move in operation, normally due to thermal growth, so to avoid high pipe stress and loads on equipment.

If significant thermal movement is expected, a pipe stress analysis should be carried out for the system and that analysis will identify the ideal location for any expansion joints required to achieve acceptable pipe stress and loads. For technical assistance contact us or use our Live Chat facility.

Q. What information do I need to design or select a rubber bellows or metal expansion joint?
A. To design or select a rubber bellows or metal expansion joint we need to know: nominal bore, end type, service, temperature, pressure and required movements. You may also specify in addition your requirements for external hardware – tie rods, hinges, gimbals – internal liner, external cover and instrumentation. Material selections should also be specified to suit the service and associated system piping. For technical assistance please contact us or use our Live Chat facility.
Q. Do you design your own metal expansion joints or rubber bellows?
A. Yes, FlexEJ has full design capability for engineered metal expansion joints and can work to any recognised standard – typically EJMA, B31.3/Appendix X, EN14917 plus PED and/or other customer specifications. Engineered rubber expansion joints are typically designed to meet the FSA guidelines plus PED and/or other customer specifications For technical assistance please contact us or use the Live Help link on this page.
Q. What kind of expansion bellow do I need for different media types?
A. Do use FlexEJ’s new Bellows Finder available on our Expansion Joints page to find recommended expansion joints by media (application) such as waters, oils, acids, etc, as well as by bore size, length, end type and more. Generally speaking, any of our HVAC bellows (rubber or metal) might be suitable for general purposes whereas our high-quality Elaflex ranges are recommended for more specific requirements you may have. And metal expansion joints can generally be designed and built to accommodate any media and temperature range, environment and pressure ranges you are likely to encounter. Do call us or use LIVE CHAT for more direct advice.
