PE Pipe Fitting Electrofusion: The development of PE pipeline system: PE is a variety of process methods of resin production, with a variety of structures and characteristics and a variety of uses, has accounted for one third of the world's synthetic resin production, in the first place. The application of PE Pipe began in the 1940s, and were originally used as telephone line pipes and mine non-pressure drainage (low-density PE pipes). In the mid-1950s, PE tubes were used to feed water (high-density PE tubes). In the mid-1960s, PE pipes began to use natural gas transmission (using mid-high density PE pipes). At present, PE pipeline system has become the second largest plastic pipe variety in the world after PVC-U pipe. It is widely used in gas transmission, water supply, sewage discharge, agricultural irrigation, oil fields, mining, chemical industry and post and telecommunications fields.
The characteristics of PE Pipe Fitting E/F: polyethylene pipe system is mainly divided into PE Pipe Fitting Socket Fusion and PE Electrofusion Fitting, due to the price of the price in engineering applications more than melt pipe fittings, but PE Pipe Fitting Electrofusion in engineering and maintenance, especially in the construction of melt pipe fittings by the external environment and human factors is less influence, so better reliability, more popular with users. Especially in the PE Fitting Gas engineering is increasingly used in the electric melt pipe fittings. At the same time, due to the complex production technology, high cost, high sales price.
At the same time, because the base of the PE Pipe Fitting E/F piece is PE material, so the PE Pipe system composed of PE pipe together solves the two major problems of the traditional pipe: corrosion and leakage at the joint. Its advantages are mainly reflected as follows:
(1) Corrosion resistance: long service life;
(2) No leakage at the joint: the electric melt pipe fittings are used to connect it, essentially ensuring the identity between the interface material and structure of the PE Pipe Fitting system and the pipe body itself, and realizing the integration of the joint and the pipe;
(3) Effective resistance to underground movement and end load: after the PE Fitting system is connected by melting method, the joint based on this method will withstand the end load without joint leakage. At the same time, the stress relaxation characteristics of PE can effectively consume the stress through deformation. Therefore, no expensive anchorage is mostly required at the junction and bend. In addition, based on its high toughness, the fracture elongation rate is generally more than 500%, and the PE pipeline system is very adaptable to the uneven settlement of the pipe base.
