Description:Grooved coupling has a fast, simple and easy installation, safe, reliable, economic, without welding, the advantages of no pollution, noise, and can absorb piping vibration transmission and heat bilges cold shrink, facilitate pipeline maintenance, without being limited by the installation site, easy to control the cost, etc. So widely conveying fluid pipelines of water supply and drainage, fire protection, air conditioning, gas, chemical, shipbuilding and other pipeline engineering adopted, it can be said to be the successful development of a major technology in the field of piping installation Life. This standard specifies the groove pipe joint product model and basic dimensions, requirements, inspection rule, mark, packing, transportation and storage. This standard applies to the nominal pressure of 2.5 MPA below the groove pipe joint.
