Polyethylene water supply electric smelting pipe

Abstract

The invention discloses a polyethylene water supply electric smelting pipe. According to the technical scheme, the two ends of a pipe body are connected with a first end head and a second end head correspondingly, the first end head and the second end head are square heads, a round joint is connected on the first end head, a square joint is connected on the second end head, a contraction step is arranged on the inner wall of the round joint, a bonding ring is further arranged at the tail end of the round joint, a plurality of vibration damping pieces are arranged on the outer wall of each of the first end head and the second end head, wherein each vibration damping piece is of a multi-layer structure, and sequentially comprises a wear-resistant plastic layer, an elastic rubber layer and ametal gasket layer from outside to inside. According to the polyethylene water supply electric smelting pipe, one end head is arranged at each of the two ends of the pipe body, the round head and thesquare head are arranged on the end heads correspondingly, so that the pipe is suitable for being connected with pipelines with different shapes, one contraction step is further arranged on the innerwall of the round head and can be used for being connected with pipelines with different pipe diameters; and the polyethylene water supply electric melting pipe has better connectivity, and is suitable for being connected with pipes with different pipe diameters.

Description

technical field [0001] The invention relates to a polyethylene electrofusion pipe fitting for water supply. Background technique [0002] In the sales and application of polyethylene piping systems, about 15% to 20% of the sales are pipe fittings. The pipe fittings of polyethylene piping systems are mainly divided into two types: hot-melt pipe fittings and electric fusion pipe fittings. Due to the price, they are widely used in engineering applications. The amount of medium heat fusion pipe fittings is more than that of electric fusion pipe fittings, but electric fusion pipe fittings play an important and irreplaceable role in engineering and maintenance, especially in construction, electric fusion pipe fittings are less affected by the external environment and human factors, so Better reliability and more popular with users. [0003] Polyethylene electrofusion pipe fittings for water supply is a relatively common pipe material. The current polyethylene electrofusion pipe...

AI Technical Summary

Problems solved by technology

[0003] Polyethylene electrofusion pipe fittings for water supply is a relatively common pipe material. The current polyethylene electrofusion pipe fittings for water supply are mostly a single cylindrical tubular structure, and the connection between the pipe body and the pipe body is not good. Not easy to connect
