Rectangular metal compensator (expansion joint)

1、 Product usage and characteristics

Rectangular metal compensators (expansion joints) are mainly used for compensating displacement or shock absorption in various smoke ducts, low-pressure gas pipelines, fan inlets and outlets, etc. They have the characteristics of good sealing, large compensation amount, and anti-aging.

2、 Applicable working conditions

Working pressure:<0.1MPa
Working temperature: -50 ℃ -600 ℃
Media: smoke, air, etc
Flanges: made as needed

3、 Structure and Materials

Rectangular metal expansion joint	Universal type (FT type) without guide tube	Sliding groove type (with guide tube)
Two universal types are used in combination to compensate for displacement in three directions	Angle type (FJ type) with guide tube	Angular combination, used for horizontal pipelines to absorb displacement in two directions, capable of bearing its own weight

1. Bellows: Carbon steel, Corton steel, stainless steel 304, 316L, 321, etc
2. Flanges and fittings: carbon steel, Corton steel, stainless steel 304, 316L, 321, etc
5. Pull rod bolts and nuts: carbon steel
