Classification of Expansion Joint: BF (VSSJA-1) type single-flange limit expansion joint, B2F (VSSJA-2) type double-flange limit expansion joint, BY (SSJB-3) type gland-type limit expansion joint, AY (SSJB) type gland-type expansion joint, flange type limit expansion joint, flange-type loose set expansion B2F type double flange limit expansion joint adopts GB/T12465-2002 standard, and the previous model of double flange transmission joint is VSSJAF.
Expanded Information：
Henan Yongan Valve manufacturer (expansion joints, filters, compensators, waterproofing casing, etc.) is a collection of research, development, production, sales and service for the integration of the production of pipeline equipment enterprise.
Double Flange Limit Expansion has a certain amount of expansion and contraction when the pipeline is subjected to thermal expansion or cold contraction has a certain compensation to protect the role of the overhaul to facilitate the installation of pumps and valves and maintenance, which is the main role of the Double Flange Limit Expansion.
Double flange limit expansion joints in the pipeline has a certain directional displacement effect on the pipeline in operation due to thermal expansion and contraction, crustal subsidence and the force produced by the important role of expansion and compensation. Therefore, the expansion joint can alleviate the blind thrust in the pipeline, play a certain protection for the pipeline, especially for the installation and maintenance of the pipeline provides great convenience.
Double Flange Limit Expansion Joint is composed of body, sealing ring, gland, extend and shorten the pipe, etc. Double Flange Limit Expansion Joint is the pump, valve equipment and pipeline connection, installation or maintenance can be adjusted according to the size of the site, you can transfer axial thrust to the entire pipeline, so that the protection of the pipeline to improve the efficiency of the work.
The role of double flange limit expansion joint has high tensile and compressive strength, superior soft sealing performance, easy loading and unloading and other properties, is widely used in electric power, metallurgy, chemical industry, water supply and drainage and sewage treatment industry, the main role of the pump valves and pipelines between the connection.
