Some knowledge points of PE pipe fittings
Plastic pipes are developing rapidly and their quality is constantly improving. At present, China's polyvinyl chloride (PVC-U) pipe, polyethylene (PE) pipe, polypropylene (PP-R) pipe-based plastic pipe industry has been initially formed. Among them, PE pipe fittings are widely used in building water supply, building drainage, buried drainage pipelines, building heating and gas pipelines, electrical and telecommunications protection sleeves, industrial pipelines, agricultural pipelines, etc. Mainly used for urban water supply, urban gas supply and farmland irrigation.

The application range of PE pipe fittings for water supply pipes is below 40 and cannot be used for hot water transportation pipes. PE pipe is a thermoplastic resin with high crystallinity and non-polarity. The appearance of HDPE in the original state is milky white, and there is a certain degree of translucency in its meager cross section. Polyethylene has excellent resistance to most household and industrial chemicals. Certain types of chemicals can cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (Si chlorinated carbon).
nano antibacterialPE pipe fittingsIt is a kind of pipe with antibacterial, hygienic and self-cleaning effect, which is co-extruded by adding nano-scale masterbatch in the inner plastic of the pipe. It is mainly used for urban water supply network, irrigation water diversion project and agricultural sprinkler irrigation project. Because the pipe connection adopts hot melt and electric fusion connection, it can effectively resist the vertical stress and axial impact stress generated by internal pressure. In addition, the production process does not add heavy metal salt stabilizers, the material is non-toxic, non-scaling, non-breeding bacteria, to avoid secondary pollution of drinking water.
Product characteristics of PE pipe fittings:
Good hygiene, self-cleaning antibacterial, long-term use without scaling, to solve the secondary pollution of drinking water.
Resistant to various chemical media, no electrochemical corrosion.
The inner wall is smooth, the friction coefficient is low, the medium flow capacity is correspondingly high, and it has excellent wear resistance.
Good flexibility, high impact strength, strong seismic resistance and deformation resistance.
Light weight, easy to transport and install.
The connection process is simple, the construction is convenient, and the comprehensive cost of the project is low.
The service life is up to 50 years.
Electrofusion fittings are recognizedPE pipe fittingsOne of the best ways to connect. Its main advantage is that it can greatly reduce the influence of human factors in the welding process, obtain high-quality connections, high strength, long service life, good air tightness, convenient operation, and high construction efficiency. This method is often used for gas pipe connections.
Hot melt butt joint is to fix and process the two connecting end faces of PE pipe fittings, clean the connecting end faces, and then place the heating plate between the two aligned pipe ends or pipe fittings, heat for a certain period of time to reach the required temperature, remove the heating plate, and quickly butt the two end faces to be welded under certain pressure until the interface is cooled, so as to realize the connection between the pipe or the pipe and the pipe fitting.
