Pipe fittings specific growth history and PE water supply pipe fittings produced with what advantages

With the wide application of PE water supply pipe parts, PE (polyethylene) can be produced by a variety of processes, is a series of varieties of resins with a variety of structures and characteristics and a variety of uses, has accounted for the world's production of synthetic resins, 3 of 1, PE pipe applications began in the 1940s, Cixi Electrofusion fittings initially used in the telephone line conduit and pit pressureless drainage (low-density PE pipe). PEPE water supply pipe parts. The mid-1960s PE water supply pipe parts imported with natural gas (using medium-high density PE pipe).

At present, Yuyao electrofusion pipe fittings PE pipe system is PVC-U pipe, the world's second largest consumption of plastic pipe varieties. Widely used in gas transmission, water supply, drainage, agricultural irrigation, oil fields, mines, chemical industry and post and telecommunications communications and other fields. At the same time, Jinhua electrofusion pipe fittings due to electrofusion pipe matrix for PE materials, PE pipes constitute the PE pipe PE pipe system unified solution to the two major problems of the traditional pipe: corrosion and joint head leakage. Its advantages are mainly.

(1) corrosion resistance: long service life.

(2) joints do not leak: the use of electrofusion pipe body connection, essentially electrofusion pipe system interface material, to ensure the consistency of the structure and the pipe itself, to achieve the integration of the joints and tubes.

(3)Capable of effective resistance to underground movement and end loads:After the electrofusion pipe system is connected using the welding method, no joint leakage will occur according to the joint end load resistance of the method. At the same time, the stress relaxation property enables effective deformation that consumes stress, thus eliminating the need for expensive anchoring in many cases at joints and bends. In addition, based on its high toughness, elongation at break typically exceeds 500 per cent.

Electrofusion pipe systems are highly resilient to uneven settlement of pipe foundations. Electrofusion is actually a type of thermal fusion, a small diameter gas piping technology that heats up molten material with a specialised instrument in the case of appliances that are not easy to use with thermal fusion, and which are electrically fused at the time of joining, or weldable plastic sheets, etc. when welding requirements are high.
