Products
We supply the five basic types of
expansion joints used in piping and ducting in large power and petrochemical
plants. All products are custom designed to suit a particular application,
using inventoried materials. Click on one of the icons below for
more information on a particular type of expansion joint.
-
- Elastomeric flex connectors are
lightweight and very flexible, available in 1/8", 1/4", and 3/8" thickness.
They are used in ducting (conveying air or gas) at pressures of less
than 5 PSIG and temperatures under 400 degrees F. Available in both
round and rectangular shapes, their purpose is primarily isolation of
mechanical vibration, even though they are capable of absorbing large thermal
movements.
-
- Rubber spool type expansion joints
are heavyweight and very rugged. They are generally used in piping
(conveying liquids) at pressures over 15 PSIG (up to about 250 PSIG depending
on diameter) and temperatures under 300 degrees F. Available in
cylindrical, concentric and eccentric reducers, their purpose is primarily to
absorb vibration and thermal movement, protecting pumps and equipment.
-
- Fabric style expansion joints are
very flexible and corrosion resistant. They are generally used in
ductwork (conveying air or gas) at pressures less than 3 PSIG and temperatures
between ambient and about 1500 degrees F. They can be made to almost any
size and configuration. Their purpose is primarily to absorb large
thermal movements and are well suited to absorb large lateral movements.
-
- Round metal bellows type expansion
joints are versatile and are well suited to high temperatures. They are
generally used in piping systems (conveying gas or liquids) at pressures
greater than 15 PSIG and temperatures between 250 and 1500 degrees F.
They are available in standard (and non-standard) pipe sizes from 1" to 96" in
diameter.
-
-
- Rectangular metal style expansion
joints are rugged and can be weld repaired by plant personnel. They are
generally used in ductwork at pressures less than 3 PSIG and temperatures
between ambient and about 1000 degrees F. They can be made to almost any
size and configuration. Their purpose is primarily to absorb large
thermal movements and are well suited to absorb large axial movements.
