Product Overview
Product Description
HDPE conduit is the preferred choice for protecting electrical wiring and telecommunication cables. It offers outstanding corrosion and chemical resistance, is flexible and durable, and is available in long reel lengths that cut down on joints and installation time.
Introduction of HDPE Electrical Conduit
HDPE electrical conduit is a high-density polyethylene pipe with excellent corrosion and abrasion resistance, widely used for cable routing in buildings, tunnels, bridges and other projects. Depending on project needs, HDPE coiled conduit can also be used alongside this straight conduit.
Advantages
1. HDPE (high-density polyethylene) is a highly crystalline thermoplastic with good waterproofing and electrical insulation, making it well suited to housing wires and cables.
2. It withstands both high and low temperatures and copes with a wide range of harsh conditions.
3. It resists crushing and provides heat insulation, protecting cables from external forces and high temperatures. It also resists acids, alkalis, salts and other chemicals, keeping cables operating safely.
4. Its toughness, flexibility and electrical insulation make it perform well during installation and in service, with a long working life.
5. It is much lighter than concrete, galvanised or steel pipe, so it is easier to handle and install, needs less labour and equipment, and greatly reduces installation costs.
Application Fields
1. HDPE electrical conduit is used for power, communication and lighting cables in buildings, tunnels, bridges and many other projects.
2. In the power sector, it protects buried cables from external damage.
3. In telecommunications, it protects fibre optic cables and keeps them stable and secure.
4. In the oil, chemical and similar industries, it protects cables in corrosive environments and extends equipment life.
Production Process
1. Raw material preparation: raw materials are blended in set proportions in a mixer for an even mix, then conveyed by vacuum feeder to an intermediate silo ready for processing.
2. Extrusion: the blended material is fed into the extruder, where it is heated, plasticised and homogenised, then formed into the pipe profile.
3. Cutting and demoulding: the pipe is cut to length and released from the mould, keeping dimensions accurate for later use.
4. Surface finishing: the inner and outer surfaces are finished smooth and even for easy installation and use.
5. Socket end treatment: where required, the socket end is prepared to make later connection and installation easier.
6. Inspection and packing: each pipe is inspected to confirm it meets the standard, then packed ready for dispatch.
