Product Introduction

The shape of metallic compensator can be circular, rectangular and bellow-form. 

The square bellow expansion joint is composed of a rectangular corrugated pipe and two rectangular end nozzles. The end pipe can be directly welded to the pipeline, or welded with a flange before connecting to the pipeline. The pull rod on the compensator is mainly a rigid support during transportation, not a load-bearing component.

There are 98 specifications(300×400~2800×3000) of rectangular metal expansion joints by their different DN.

Application Scope

Rectangular corrugated compensator is a new material, which is used for marine fan, pipe fan, boiler fan, air conditioning fan, smoke exhaust fan and roof fan.

Import and export of various pumps, valves, and air compressors; Various types of fire protection piping, air conditioning piping, steam piping, etc; General factory piping and occasions requiring hygiene; Mechanical equipment piping, where shock absorption and compensation for thermal displacement are required; Domestic water piping and occasions that require flexible connections.

Advantages 

1. ​One of the main advantages of rectangular metal bellows expansion joints is their exceptional durability. Made from high-quality stainless steel, this product is built to withstand harsh environments, ensuring long-term performance and reliability. The use of high-quality materials also makes it corrosion-resistant, extending its lifespan and reducing maintenance requirements.
​2. In addition to their durability, expansion joints are easy to install and maintain. With flange and pipe connection options, it integrates seamlessly into existing systems, minimizing downtime and installation costs. Additionally, its low maintenance requirements make it a cost-effective solution for businesses looking to optimize operations.
3. ​Rectangular metal corrugated bellows expansion joints are also designed to achieve efficient thermal expansion and vibration absorption, contributing to the overall integrity and safety of the system. Its ability to accommodate movement and misalignment helps prevent damage to critical components and ensures smooth, uninterrupted operation.

Product features

1. The product can greatly reduce the vibration and noise of the pipeline system, and fundamentally solve the problems of interface displacement, axial expansion and different centrality of various pipelines.
2. It can be made into acid resistant, alkali resistant, corrosion resistant, oil resistant, heat resistant and other varieties according to different materials, and can adapt to various media and environments.
3. The material is polar rubber, with good sealing performance, light weight, convenient installation and maintenance, and long service life. However, contact with sharp metal instruments should be avoided to avoid piercing the sphere.
4. If it is used overhead, it can be equipped with elastic support, and the bolts shall be tightened by diagonal method during installation.
5. If the pipeline pressure is too high, use limit bolts to connect the flanges at both ends.
