Pipeline Bellows expansion joint

Pipeline Bellows expansion joint can be divided into metal corrugated compensator and Flexible expansion joint (see NO.5 ：).

The Bellows expansion joint is a subdivided compensator with multiple waveforms made by pressing steel plates, which absorbs the thermal displacement generated by the pipe after heating, and has the advantages of large compensation and low rigidity. Bellows expansion joint can be used in large thermal pipeline systems.

Purpose: The Bellows expansion joint an compensate axial, lateral and angular directions, has no thrust, simplified bearing design, corrosion resistance, high temperature resistance, noise reduction and vibration reduction, etc. It is suitable for all kinds of pipelines.

The Bellows expansion joint for the pipeline is mainly achieved through the expansion and contraction of the metal bellows, and the compensation amount of the subdivided corrugation is not more than 20mm,

Caliber size: ≥80mm, square pipes can also be made.

Compensation direction: divided into axial, radial and universal.

Material: According to different temperature media, generally use Q235B, SUS304, 316L stainless steel,

Special anti-corrosion pipelines are generally lined with anti-corrosion materials

Connection method: welding type, flange type

Pressure rating of the Bellows expansion joint produced by our company: ≤4.0mpa
