The impurities generated during the welding

When the position of the clamp ring is determined, the gap size between the two ends of the pipes should be determined by calculation based on the elongation of the pipeline and the ambient temperature during construction. The size deviation should be guaranteed during construction.

Under a certain movement, the larger the error in the height and width of the weld between the clamp ring and the pipe end and the verticality of the plane of the clamp ring and the axis of the pipe end, the smaller the expansion and contraction of the joint and the worse the use effect.
of the pipe end and the clamp ring will affect the sealing performance of the pipe end. Before installation, the welding slag on the sealing surface should be removed to ensure the sealing performance.

3. Overview
Groove connection technology, also known as clamp connection technology, has become the first technology of choice for connecting liquid and gas pipelines. Although this technology was developed in China later uk email list than abroad, it has been quickly accepted in the domestic market due to its advanced technology. Since its development in 1998, after only a few years of development and application, it has gradually replaced the two traditional pipe connection methods: flange connection and welding connection. Not only is the technology more mature, but it has also been generally recognized by the market, and it is actively supported by national laws and policies.

The use of grooved fittings connection technology makes the complex process of connecting pipes simple, fast and convenient. This has become a major step forward in pipe connection technology.

4. Introduction to Grooved Fittings
Grooved fittings include two main product categories: (1) Fittings that play the role of connection and sealing, including rigid couplings, flexible couplings, mechanical tees and grooved flanges;
