I. The rigid coupling is mainly composed of the coupling body, bolts, gaskets, pressure plates and other parts. The coupling body is a tubular structure, usually made of materials such as stainless steel, carbon steel, and cast steel. Its inner wall adopts a notch design, which can increase its coupling force. Bolts are components used to tighten the coupling body, and their structures are usually hexagonal heads or square heads. Gaskets are used to relieve the pressure of the coupling on pipelines and pipe fittings. Commonly used materials include rubber, plastic, etc. The pressure plate is a part used to strengthen the pressure of the coupling body and is usually a metal product.
II. The rigid coupling, also known as a pipe coupling, is a tool used to fix pipelines and pipe fittings. It is widely used in industries such as construction, chemical, petroleum, water conservancy, heating, ventilation, and air conditioning.
III. Characteristics
1. Solid structure: The rigid coupling mainly adopts metal structure, with strong pressure resistance and deformation resistance, long service life.
2. Strong coupling force: The inside of the coupling body is engraved with notches, which can increase the force of the coupling holding pipelines and pipe fittings to ensure that they will not loosen or fall off.
3. Wide application range: The rigid coupling are suitable for various pipelines and pipe fittings, including steel pipes, cast iron pipes, pipe fittings, PE pipes, PVC pipes, etc.
4. Convenient to use: The rigid pipe coupling uses bolt tightening, which is both convenient and fast and suitable for construction sites.
