1 flange connection
General flange connection speed, convenient construction, simple tools, but in terms of safety and confusion, most of the project regulations are not met. Generally, low pipelines are low, and this type of connection method is often used to move the application of pipes, such as mud pipelines.

2 groove connection
Also known as the card hoop connection technology, it has become the first push technology connected by the current liquid and gas pipelines. Although this technology has been developed overseas later than overseas in China, due to the innovation of its technology, it was quickly accepted by the Chinese market. The development of ditch parts connection technology makes the complicated pipeline connection process simple, convenient, and convenient. Make the pipeline connection technology a big step forward. The groove pipeline contains two large products:
① The pipes that connect the sealing effect include rigid connectors, flexible joints, mechanical three -way and pipeline -type flang;
② Pipes that connect the transitional effect include bending pipes, three links, four -way, four -diameter tube, blind plate, spiral welded pipe, etc. There are three main components of the trench connector parts connected to the sealing effect: sealed rubber rings, card holes and lock bolts. The silicone sealing ring located in the inner layer is placed on the outside of the connected pipe, and it is consistent with the tube rolled in advance. Then go to the outer buckle of the rubber ring, and then use two bolts to be fastened. Because of its unique enclosed structural design, its silicone sealing rings and card holes are selected to promote the groove connecting parts to have a good closure, and the stress of the tube is improved, and its confinement is correspondingly improved.

3 Card hoop pipeline connection
As an advanced pipeline connection method, it can be set up and paved, with both steel connectors and flexible connections. Therefore, it has a wide range of applications. Suitable for waterfighting systems, air -conditioning hot and cold water systems, water supply systems, crude oil pipeline systems, thermal power and military pipeline systems, sewage treatment pipeline systems, etc.
The spiral steel pipe connection characteristics, the groove connection prompts the pipeline connection operation is simple, which is beneficial to construction security, stable system performance, convenient maintenance, time -saving and time -saving, so it has good economic income. Select a card hoop connection. Although the price of a single accessory of the card hoop is higher, the overall efficiency of the entire pipe network is higher than the flange connection.
