UNIVERSAL EXPANSION JOINT

STAINLESS STEEL EXPANSION JOINT

PRODUCT SHEET

The standard axial expansion joint is the most common ex-

pansion joint. It is an assembly of a bellow welded together

with the connections. Possible connections are welding

ends or flanges.

The standard axial expansion joint can absorb movements

caused by temperature differences in a piping system

It is mainly designed to absorb movements along the axis

of the pipes.

Also lateral and angular movements can be absorbed.

> DESCRIPTION

> KEY FEATURES

Absorbs movements in all directions,

but it is most appropriate axial

movements.

Pressure thrust not restrained: reaction

pressure force acts on piping.

Standard grade of bellow is AISI 316.

Flanges are standard made out of zinc plated

steel for swivel flanges and carbon steel with

corrosion protection for fixed flanges.

Stainless steel flanges are also available.

Pipe-ends and bund rings are manufactured

in AISI 316 grade.

> MATERIAL PROPERTIES

The bellow is designed according to the most re-

cent EJMA standards.

Assembly is done according to EN 14917 / ISO

15348. Assemblies are possible with welding

ends (ASME B36.10), flanges according to

European standard (EN 1092-1) or

ANSI standard (ASME B16.5).

Flanges according JIS standard (JIS B2220) are

also possible on request.

Application where axial movement has to be

absorbed. An expansion joint is necessary

between the intermediate anchor (IA) and

both main anchors (MA).

This shows an application where axial as well

as lateral movements have to be absorbed.

The pipe extension or contraction between

the intermediate anchor IA and directional

main anchor DMA, which can only move in

one direction, creates a small lateral move-

ment. Contraction/extension between the

points DMA and MA causes axial movement.
