hdpe winding structure-wall pipe
hdpe pipe with spirally enwound structured wall, an extra-large-diameter high-end buried water drainage pipe, is a new kind of safe and green pipe. it is a type of profiled structure-wall flexible tubing, which has a smooth inner wall, a spiral stiffening rib as its outer wall, and rib interface is manufactured via o-type spiral winding technology.
technical standard
the production and construction of products strictly implement international national standards.

connection type
socket type electrical connection
the thermal energy will melt the polyethylene material on the contact surface of the socket, and the pe molecules of the interface will solidify after the interpenetration and cooling of the pe molecular chains of the contact surface, so as to achieve the purpose of connection.
the characteristics of electrofusion connection at construction site.
the strength of the connection is better than the strength of the pipe, and the connection is simple and convenient.
throttling socket connection.
nachan introduced patented technology to set up an independent annular ring on the socket or socket, and the mechanical occlusion socket was carried out, and the sealing ring was used, the double-layer seal was guaranteed, and the safe zero leakage was achieved. convenient construction, without the use of third-party equipment; the adaptability of pipeline to construction conditions can be improved.
