HPPM squared Electrical Double Wall Corrugated Pipe
This is a new pipe wall material using polypropylene as the main raw material that is heat resistant, oxygen resistant and nano flame retardant modified, whilst adopted high strength corrugated wall tube design and processing technology. It has novel structure, high pressure resistance, quick and convenient construction. High temperature resistance, flame retardant, aseismic, long service life, etc.
Good flexibility: good softness can be used to settle the ground settlement or the change of the foundation, so as to ensure the protection of the pipe to the cable.
Material saving: less material can be released on the premise that pipe material achieves the same performance.
High heat resistance: the main material is not compound polypropylene, the temperature of vica is above 135C, and the external pressure is maintained at high temperature.
Energy conservation and environmental protection: the main material consists of two elements: carbon and hydrogen, which can be used for recycling, and there is no white pollution in the process of production and collection.
Safety: no conduction, no heat transfer, good line performance, meet the requirements of high voltage power safety.
Corrosion resistance: corrosion of acid, alkali, salt and other chemical media, and electrochemical erosion. The service life is over 50 years.
Smooth pipe wall: smooth inner surface, low friction coefficient, contact state with cable, low drag resistance.
Low temperature resistance, span large working temperature range, can adapt to a variety of climatic conditions of the construction.
High sealing degree: it can be connected with a special card, without welding seams and flying edges, and it will not scratch the cable.
Strong ring stiffness: special single-wall corrugated structure design and high elastic modulus of the material, make its have epipodium stiffness, high crushing strength.
》 Applied Area
HPPM square power double wall corrugated pipe is mainly used in the urban and rural areas of high voltage power transmission lines above 10KV.
HPPM square power double wall corrugated pipe is connected by a special clamp. When using the special clamp connection, the pipe must be kept in the same line with the nozzle, the elastic sealing ring shall be set on the nozzle, and then the clamp will be fastened to the end of the two pipes. Pipe material should be made by manual transmission when laying in the trench, and it is forbidden to roll down the ditch.
