HDPE is the abbreviation of high-densitypolyethylene.
Polyethylene pipe is widely used in the fieldof water supply and drainage manufacturing because of its high strength, hightemperature resistance, corrosion resistance, non-toxic, abrasion resistanceand other characteristics. Because it will not be rusted, so it is an idealpipe to replace iron pipes for water supply.
Characteristics of HDPE pipe,
1.Good sanitaryperformance: HDPE pipe production processing without adding heavy metal salt forstabilizing, non-toxic material, no scaling layer, no bacteria, a good solutionto avoid the second time of pollution of urban drinking water.
2.Excellent corrosion resistance: except of small part of strongoxidants, it can resist the corrosion of a variety of chemical media and noelectrochemical corrosion, either.
3.Long service life: under the same working temperature andworking pressure, HDPE pipe can be used for more than 50 years.
4.Good impact resistance: HDPE pipe has good toughness,high impact strength, and it will not cause the pipe to break when heavy thingshit the pipe.
5.Connection performance: the strength of HDPE pipehot-melt or electric fusion interface is higher than pipe body, and the jointwill not be disconnected due to soil movement and working load.
6.Good construction performance: the pipeline is light, sothe welding process is simple and convenient, and the comprehensive cost of theproject is low.
1.Electric fusion: special electric fusion welding machineis used to connect straight pipe with straight pipe and straight pipe with pipefittings. Generally, it is mainly used for pipes below 160mm.
2.Hot melt for butt joint: the special butt-welding pipe isused to connect, generally used for more than 160mm pipe.
3.Steel and plastic connection: it can be connected byflange, threaded and other methods.
4.In order tofacilitate construction and ensure construction quality, related tools shallalso be prepared.
1. Clamped and clean the welding ends 2. Adjust and grind the welding ends 3.Align the welding ends 4. Pressed and welded 5. Pressure relief and cooling.
