The theme of this article is "High-quality supplier of pipeline fittings in Yunnan". Building pipeline fittings are an indispensable part of building water supply and drainage, heating, refrigeration and other systems. Their quality and performance directly affect the normal operation of the entire system. Here is an introduction to some common building pipeline fittings:
1. Connection fittings: Connection fittings are mainly used to connect different pipe sections to achieve continuous transportation of pipelines. Common connection fittings include flanges, flexible joints, clamps, and pipe clamps. Flanges are fittings with flanges, which are mutually matched with the flanges of another fitting, and then fastened with bolts or nuts to form a sealed unit. Flexible joints are a detachable connection method. It is composed of a fixed joint and a detachable pipe section, which are fastened or loosened by rotating the nut on the joint. Clamps and pipe clamps are used for connecting pipes of different diameters, and their fastening methods are also different.
2. Direction-changing fittings: Direction-changing fittings are mainly used to change the direction of pipelines to meet construction requirements. Common direction-changing fittings include elbows and bends. Elbows are used to convert straight pipelines into curved pipelines of a certain angle, and can be divided into different types such as 90-degree elbows and 45-degree elbows. Bends are used to connect two or more pipes and change their directions.
3. Diameter-changing fittings: Diameter-changing fittings are mainly used to adjust the diameter of pipelines to adapt to different flow requirements. Common diameter-changing fittings include reducers, reducing elbows, and branch outlets. Reducers are used to convert large diameter pipes into small diameter pipes, reducing elbows are used to connect pipes of different diameters, and branch outlets are used to connect branch pipes to the main pipeline.
4. Branching fittings: Branching fittings are mainly used to divide the main pipeline into multiple branches and achieve diversion. Common branching fittings include tees and crosses. Tees have three interfaces and can be used to divide the main pipeline into two branches, while crosses have four interfaces and can be used to divide the main pipeline into three branches.
5. Sealing fittings: Sealing fittings are mainly used to seal the connections of pipes to ensure that fluid does not leak. Common sealing fittings include gaskets, caps, welded plugs, and pipe plugs. Gaskets are usually used at flange connections, caps are used at the ends of pipelines, welded plugs are used to close openings in pipelines, and pipe plugs are used to block unused pipe openings.
6. Fixing accessories for fittings: Fixing accessories for fittings are mainly used to fix pipelines and prevent them from moving or being damaged. Common fixing accessories for fittings include clamps, hangers, brackets, brackets, and pipe clamps. Clamps are used to fix pipes on brackets, hangers are used to suspend pipes, brackets and brackets are used to support and stabilize pipes, and pipe clamps are used to fix pipes on brackets.
The above is an introduction to some common building pipeline fittings. They play an important role in the water supply and drainage, heating, refrigeration and other systems of buildings. When purchasing and using these fittings, attention should be paid to the selection of quality and the methods of use to ensure that they can work stably for a long time and ensure the normal operation of the building.
