The most common way to connect large diameter spiral steel pipe is to weld, but in some projects, it is often used in the form of screw connection, flange connection, socket connection and groove connection.
Connection mode
Welding and flange connection
Connection features
Welding, flange connection belongs to l spiral steel pipe traditional pipe connection, in safety, sealing performance, cost of space, the repair efficiency has far cannot satisfy the market demand
Scope of application
Water pipe connection
Oil, natural gas pipeline connection
Chemical pipe connection
Electricity pipe connection
Connection mode
Grooved pipe connection
Groove pipe connection technology is also called the clamp connection technology, has become the current first technology of liquid, gas pipeline connections, although the technology in domestic development time later than abroad, but because of its advanced technology, was received by the domestic market soon. The application of the grooved pipe connection technology, make complex pipe connection process becomes simple, fast and convenient. The pipeline connection technology major strides forward.
Groove connection pipe fittings include two categories of products: (1) connecting sealing effect of pipe fittings with rigid joints, flexible joints, mechanical tee and the groove of the flange; (2) connect the transition role of pipe elbow, tee, four-way, reducer, and blind plate, spiral welded pipe, etc. Connecting sealing effect of groove connection pipe fittings mainly has three parts: the sealing rubber ring and clamp and locking bolt. Is located in the inner lining of the rubber seal on the outer edge of the connected pipes, and in conformity with the advance of rolled groove, and buckle on the outside of the rubber ring clamp, then with two bolts. Due to the rubber sealing ring and clamp adopting special seal structure design, make the groove fittings with good sealing, and with the increasing of inner fluid pressure, the sealing enhanced accordingly.
Groove connection makes the pipe connection operation is simple, is advantageous to the construction safety, the system has good stability, easy maintenance, save work time, so has the good economic efficiency. The clamp connection, although the clamp single accessories price is higher, but the whole pipeline installation of comprehensive benefit is higher than the flange connection.
Suitable for liquid, gas pipe connection
Connection mode
Pipe clamps connection
Connection features
Coupling connection as an advanced way of pipe connection, which can be set can also be buried Ming, the joint rigidity, also has a flexible joint. Therefore has wide scope of application.
Scope of application
Points: according to the system can be used for fire water system, air conditioning hot and cold water system, water supply system, petroleum and chemical piping systems, thermoelectric and military industry pipeline system and sewage pipe system, etc.
According to the points of piping material: can be used to connect steel pipe, steel pipe, stainless steel pipe, plastic pipe, ductile iron pipe, plastic pipe and steel pipe with thick wall joints and flange joint soft valve.
