Background

Pipe broadly refers to a pipe used in a pipeline to transport various fluids. The common parts include cast iron pipes, steel pipes, nonferrous metal pipes, nonmetal pipes, plastic pipes, etc. Typically, the tubes are circular, and there are shaped tubes that are made with non-circular cross-sections. The materials for manufacturing the tube are many, and metals such as steel, iron and copper, and non-metals such as ceramics, plastics and rubber are commonly used. The plastic pipe is taken as an important component of modern chemical building materials, and is widely accepted by the majority of users due to the excellent performance, sanitation, environmental protection, low consumption and the like.

Generally, the diameter of a pipe can be divided into an outer diameter, an inner diameter, and a nominal diameter. The outside diameter of a pipe whose pipe material is a seamless steel pipe is denoted by letter D, and then the dimensions of the outside diameter and the wall thickness are added, for example, a seamless steel pipe having an outside diameter of 108, the wall thickness is 5MM, denoted by D108 × 5, and a plastic pipe is also denoted by the outside diameter, for example, De63, and others, such as a reinforced concrete pipe, a cast iron pipe, a galvanized steel pipe, etc., are denoted by DN, and are generally denoted by a nominal diameter in the design drawing, which is a standard artificially defined for the convenience of design, manufacture and maintenance, and is also a specification name of the pipe (or pipe fitting) rather than the nominal diameter.
