Introduction of grooved pipe fittings
Grooved pipe fitting is a new type of steel pipe connection, also known as clamp connection, which has many advantages. In the connection of modern pipe fittings, there are various specifications, models and connection methods. The application of grooved pipe connection technology makes the complicated pipeline connection process simple, fast and convenient.
Standard for grooved pipe fittings
Production and operation specifications: square pipe: 30X30-800X800mm, rectangular pipe: 20X40-800X 1200mm, wall thickness 1.5-30mm, seamless steel pipe: 32-630mm, wall thickness 2-30mm, cold-drawn seamless steel pipe:.
Main materials: Q235235B, 20#, 45#, Q345B, 345C, Q345D, 16mn, 27SiMn, 12Cr 1MoVG, 15CrMo? , 10CrMo9 10, etc.
Implementation standards: GB/T309/KOOC-0/,GB/T/KOOC-0/3793, GB/T6728, GB/T8/KOOC-0/62, GB/T8/KOOC-0/63, GB/T3087 and GB/T53.
The main application fields of products: large-scale building steel structure engineering, large-scale gymnasium, exhibition center, lifting machinery, ships? After years of pioneering and innovation, large-scale national projects such as manufacturing, road and bridge, power engineering, machinery manufacturing, coal mine, building piling, water treatment, airport terminal, mine support and vehicle manufacturing have gradually formed a sales network with serialized product specifications and complete varieties.
Grooved pipe fittings are usually divided into grooved pipe fittings and grooved pipe fittings. Grooved pipe joints can be divided into rigid grooved pipe joints and flexible grooved pipe joints. Grooved pipe fittings mainly include mechanical tee, mechanical tee, mechanical reducing tee, 90-degree elbow, 45-degree elbow, 22.5-degree elbow, clamp, positive tee, reducing tee, concentric head, eccentric head, single flange, short pipe flange and blind plate. Pipe fittings, such as elbow, tee, cross, reducer, etc. , collectively known as the trough joint collection system, the joint parts of its flat end are all processed into the same ring as the pipe joint parts.
According to the design specification of automatic sprinkler system, the pipe connection of the system should adopt groove joint or thread and flange connection; In the system, pipes with a diameter equal to or greater than 100mm shall be connected by sections with flanges or grooved connectors. Grooved pipe fitting connection technology, also known as clamp connection technology, is the first technology to connect liquid and gas pipelines at present. Although this technology developed later in China than abroad, it was quickly accepted by the domestic market because of its advanced technology.
Summary: According to the above words, we must know something about the relevant production standards. In recent years, the grooved pipe fittings produced in China are not only technically more mature, but also widely recognized by the market, and actively guided by relevant national laws and policies, making the pipeline connection technology a big step forward. Grooved pipe fittings have a wide range of applications and a large market demand. After we know the standards of these grooved pipe fittings, it will be of great help for us to further understand grooved pipe fittings.
