Stainless steel corrugated compensator

Stainless steel corrugated compensator, also known as metal expansion joint, is a flexible component used to absorb thermal expansion and contraction, mechanical displacement and vibration of pipelines. It uses stainless steel corrugated pipes as its core, compensating for axial, lateral, or angular displacement of the pipeline through the elastic deformation of the ripples, which can effectively reduce the stress of the pipeline system and protect equipment and pipelines from damage. Suitable for high-temperature and high-pressure pipeline systems in industries such as petroleum, chemical, and power, it has the characteristics of strong compensation capability, excellent corrosion resistance, and long service life.

structural characteristics

Multi layer stainless steel corrugated pipe structure, with good elasticity and large compensation, can absorb axial, lateral, and angular displacement.


The supporting limit rod and guide structure can limit excessive displacement, prevent the instability of the corrugated pipe, and improve operational safety.


Stainless steel material has excellent corrosion resistance and is suitable for high temperature, high pressure, and corrosive media working conditions.


The flange connection method is easy to install and can quickly connect with various pipeline systems.


The overall structure is compact, with low flow resistance, and does not affect the efficiency of medium transportation.


Design specifications: comply with GB/T 12777 and HG/T 20615 standards.

Connection method: flange connection (expandable to welding, clamp connection).

a. TF-16P universal type: suitable for compensating pipelines at room temperature, medium and low pressure

b. TF-25P high temperature type: suitable for compensating high temperature and high pressure pipelines

c. TF-16P corrosion-resistant type: suitable for compensating pipelines in strongly corrosive media
