The effect of using expansion joint

Expansion Joint is designed to relieve mechanical stress and they are made from a variety of materials including stainless steel, PTFE and braided flexible metal. Expansion Joint has lots of advantages due to their flexible nature, which makes it suitable for many functions, including absorbing sound, heat and shock. Our Expansion Joints are specifically designed to reduce the need for maintenance, repairs and manual assistance. 

Advantages of Expansion Joint:

Expansion Joint provides superior performance, reliability and service life, thereby increasing equipment safety and mechanical integrity. Inserting specially designed products in piping systems, Expansion Joint is able to:

 1.reduce displacement

 2.improve thermal stability

 3.release system strain caused by thermal changes, load stress, pump pressure fluctuations, sediment wear

 4.reduce noise level

 5.compensate for eccentricity

 6.eliminate electrolysis between different metals

Application of Expansion Joint:

● Any cryogenic system requiring thermal expansion, settling, or other chemically compatible motion

● Misalignment compensation

The rubber expansion joint produced by CDSR are mainly used on dredgers for the connection between dredge pumps and pipelines, as well as the connection between pipelines on deck. Due to the flexibility of the hose body, it can provide a certain amount of expansion and contraction to compensate for the gap between the pipes and facilitate the installation and maintenance of the equipment. Our rubber expansion joint has a good shock absorption effect during work so as to protect the equipment.

Features:

(1) Withstand both negative pressure and positive pressure

(2) Excellent wear resistance

(3) Good scalability

(4) Good shock absorption performance
