Three ways to connect steel pipes

　　Do you know what are the three methods of connecting spiral steel pipes? Let me briefly introduce them to you.

　　The spiral steel pipe is a strip of jointless hollow section. It can be used as a pipeline for transporting fluids such as oil, natural gas, natural gas, water, and some solid materials. The use of seamless steel pipe to manufacture ring parts can improve material utilization, simplify the manufacturing process, save materials and processing, such as rolling bearing rings, jack sets, etc., widely used in the manufacture of steel pipes.

　　The common connection method is welding, but in some projects, threaded connection, flange connection, socket connection, groove connection, etc. are often used.

　　First, welding and flange connection

　　Welding and flange connection belong to the traditional l-type spiral steel pipe connection method, which is far from meeting the market demand in terms of safety, sealing, cost space and repair efficiency.

　　Second, slotted pipe joints

　　The trough type pipe joint connection technology, also known as the clamp connection technology, has become the current liquid and gas pipeline connection technology. Although the technology is developed later in the country, it is rapidly favored by the domestic market due to its advanced technology. The application of the grooved pipe joint technology makes the complicated pipe connection process simple, fast and convenient. This is a major advancement in pipe joining technology. The groove connection makes the pipe connection operation simple, which is beneficial to construction safety, good system stability, convenient maintenance, time and labor saving, and therefore has good economic benefits. Use a clamped connection. Although the price of single pipe clamp fittings is higher, the overall efficiency of the entire pipe network installation is higher than that of the flange connection.

　　Third, the pinch joint

　　As an advanced pipe connection, the clamping pipe can be directly buried or buried, including steel joints and flexible joints. Therefore, it has a wide range of applications.

　　The above is the three methods that I want to summarize the connection of steel pipes, which can help everyone.
