[0002] Drain pipes are a system of pipes and ancillary facilities used to collect and discharge sewage, wastewater and rainwater. They are responsible for the drainage of rainwater, sewage, farmland irrigation and drainage, etc. Drain pipes can be made of different materials, such as plastic, concrete and reinforced concrete. The drainage pipe system includes trunk pipes, branch pipes and pipes leading to treatment plants. They play a role in drainage on the streets or anywhere else. The types of pipes include galvanized iron pipes, copper pipes, stainless steel pipes, aluminum-plastic composite pipes and stainless steel composite pipes. Each pipe material has its specific performance and applicable occasions. The joint is a component used to connect water pipes. According to the use method, the water pipe joint can be divided into: external threaded end-type water pipe joints, ferrule-type water pipe joints, and self-fixing water pipe joints. The pipe joint is a connection tool between pipes and is a detachable connection point between components and pipes. It plays an indispensable and important role in pipe fittings. It is one of the two main components of the pipeline.
