Single Type Expansion Joint- Tied (MST)

This model,with the tie-rod assembly,is an improvement on the Single Type Expansion Joint. This model is designed for pipelines with lateral movements. Tie-rods are designed to sustain the thrust generated during operation.

Universal Type Expansion Joint-Un Tied (MUN)

A universal expansion joint contains two bellows joined by a intermediate pipe for the purpose of absorbing any combination of the three basic movements,i.e. axial movements,lateral deflection,and angular rotation. This model is used for pipelines with bigger lateral movements than the single type

Hinge Type Expansion Joint (MSH)

A hinged expansion joint contains one bellows and is designed to permit angular rotation,by the use of a pair of pins through hinge plates attached to the expansion joint ends. The hinge arms and hinge pins must be designed to restrain the thrust of the expansion joint due to internal pressure. Hinged expansion joints should be used in sets of two or three to function properly.

Gimbal Type Expansion Joint (MSG)

A gimbal expansion joint is designed to absorb combined movements by the use of two pairs of gimbal arm and gimbal pin,which restrains the thrust of the expansion joint due to internal pressure while the bellows is designed to absorb angular rotation only. Gimbal expansion joints should be used in sets of two or three to function properly just like hinged expansion joints.

Pressure Balanced Type Expansion Joint (MSB)

If the diameter of the pipe is excessively large or high pressure is running in the pipes,anchors must be installed to restrain the thrust of the expansion joint. However when conditions would not allow the installation of anchors,this pressure balance type expansion joint has to be used. According to the location of installation,L type (MSB-Bent Pipe Balanced) or S type (MSS-Straight Pipe Balanced type) is used.
