Easy Absorb Rectangular Expansion Joint For Low Pressure Ducting Systems

Rectangular Expansion Joint For Exhaust Gas and pump

Product Description

Rectangular expansion joints absorb thermal expansion as well as axial, lateral and angular movement in low-pressure and negative-pressure applications like exhaust systems, flue ducts, ventilation. Durable enough to withstand high temperatures yet flexible enough to compensate for various movement, rectangular expansion joints are engineered to provide a custom fit with connecting ducts and equipment with single-miter, double-miter, and camera-fold corner designs providing a menu of flexibility options.

The main application of steel products is the tail gas system of the steel mill. It mainly solves the axial compensation of the compensator and the vibration caused by the pulsation. It needs anti-corrosion and heat insulation. The material of the wave joint is 316L and 254Mo.

Classification

According to different needs,we can offer you general metal expansion joint, pressure balance compensator, large diameter straight pipe pressure balance compensator, internal and external pressure balance corrugated compensator, bypass compensator, rotary compensator for steam pipe network etc.

Specifitions

Design pressure is -0.25MPa

Design temperature is 300. °C
Path range: no limit

Function

It can compensate the axial, lateral and angular displacement and mechanical deformation of pipeline and container caused by thermal expansion and contraction, it can also used to reduce the noise and vibration of pipeline!

Working theory:

Expansion and contraction deformation of bellow.(An elastic element)

Structure:

It is mainly consist of bellow, end pipe, flange, tie rods and draft tube etc.
