Three types of spiral steel pipe connection

Flange connection

General flange connection speed, convenient construction, simple tools, but in terms of safety, airtightness can not meet most of the project regulations, general low pressure pipeline, often move the application of pipeline suitable for this type of connection, such as mud drainage pipeline.

Trench connection  

Also known as clamp connection technology, has become the current liquid, gas pipeline connected to the first technology, although the development of this technology in China later than overseas, but because of its technological innovativeness, quickly accepted by the Chinese market. The development of pipe trench fittings connection technology, so that the complicated pipe connection process becomes simple, convenient and convenient. It makes the pipe connection technology take a big step forward. Trench

Connection fittings contain two big products:

Pipe fittings with connection sealing effect are rigid joints, flexible joints, mechanical tees and pipe groove flanges.

Pipe fittings for the role of connection transition are elbow, tee, cross, reducer, blind, spiral welded pipe and so on.

To connect the sealing effect of the groove connection fittings are mainly composed of three parts: sealing rubber ring, clamps and locking bolts. Located in the inner layer of the silicone sealing ring placed on the outside of the pipe to be connected, and with the rolling of the pipe groove beforehand in line, and then go to the outside of the rubber ring buckle on the clamp, followed by two bolts can be fastened. Because of its silicone sealing ring and clamp selection of unique can be closed structure design, prompting the groove connectors have a better sealing, and with the increase in fluid pressure in the pipe, its sealing is correspondingly improved.

Clamp fittings connection As an advanced pipe connection, it can be installed both in the open and paved, and has both steel joints and flexible joints. Therefore, it has a wide range of applications. Suitable for fire fighting water system, air conditioning hot and cold water system, water supply system, crude oil chemical piping system, thermoelectric and military piping system, sewage treatment piping system and so on.

Spiral steel pipe connection characteristics, groove connection prompts the pipe connection operation is simple, beneficial to construction safety, stable system performance, easy maintenance, time-saving and time-saving, so it has better economic returns. Selection of clamp connection, despite the higher price of individual fittings of the clamp, but the overall benefits of the whole pipe network installation is higher than the flange connection.
