Expansion Joint, Union Type A

The Union-type rubber joint single sphere is composed of a multi-layer scraping nylon curtain cloth, an outer plastic layer composite rubber tube. Solve the traditional rubber takeover due to poor interchangeability and poor sealing factors of easy leakage defects, the use is more reliable At the same time, you can also choose different materials according to different use conditions, with a wider range of applications. Suitable for water, oil, compressed air, etc., is the better product of pipeline inlet and outlet connection

Expansion Joint, Union Type A FAQs

Q 1. What is the Features for Union Type Expansion Joints?
A.

Union type expansion joints are the choice when an economical threaded pipe connection is needed. They are engineered to absorb thermal movement, offset and misalignment in piping systems. Due to the design of the union type expansion joints having a rubber body it eliminates metal to metal contact stopping the electrolytic process. The union type expansion joints comes standard with galvanized ductile iron female unions. SS304, SS316 and Bronze unions are also available. The union type expansion joints are also available on special request with the following female union threads: NPT, BSPT and other standards.

Q 2. What is the Working Medium for Dismantling Joints?
A.

Vapour, compressed air, cold&hot water, sea water, oil, weak acid
