Performance and Advantages

Steel wire mesh reinforced polyethylene (PE) composite pipe for water supply is a new type of pipe with excellent performance, widely used in oil fields, power plants, chemical and petrochemical enterprises, waterworks, municipal gas, seawater utilization pipelines, and other fields.

Standards for steel wire mesh reinforced polyethylene (PE) composite pipes and fittings for water supply: CJ/T189--2007 and GB/T32439-2015

Application fields of steel wire mesh reinforced plastic polyethylene composite pipes.

Municipal Engineering: Urban building water supply, drinking water, fire water, heating network return water, gas, natural gas transportation, underground drainage channels for highways, etc.

Oil and Gas Fields: Oil-containing wastewater, gas field wastewater, oil-gas mixtures, pipes used in secondary and tertiary oil recovery and gathering processes.

Chemical Industry: Acid, alkali, and salt manufacturing industries; transportation of corrosive gases and liquids in the petroleum, chemical, fertilizer, pharmaceutical, textile, dyeing, rubber, and plastics industries.

Process pipes and discharge pipes for solid powders.

Power Engineering: Process water, return water, water supply, fire water, dust removal, and slag transportation pipelines.

Metallurgy and Mining: Used for transporting corrosive media in non-ferrous metal smelting and for pulp, tailings, ventilation pipes, and process pipes.

Seawater Transportation: Seawater desalination plants, coastal power plants, and seawater transportation in coastal cities.

Shipbuilding: Ship sewage pipes, drainage pipes, ballast water pipes, ventilation pipes, etc.

Agricultural Irrigation: Deep well pipes, filter pipes, dark ditch transportation pipes, drainage pipes, irrigation pipes, etc.

Connection Method: Electrofusion Fitting Welding

1. Prepare the necessary tools. The outer surface of the pipe must be roughened, and the insertion depth must be marked.

2. Before construction, perform a welding peel test to ensure welding effect, adjust the correct parameters before construction, and ensure that the project can be completed on schedule.

3. For welding pipe fittings under 200, within 30 meters, a four-square-millimeter cable can be used. For more than 30 meters, a six-square-millimeter or larger cable must be used, with a maximum length of 100 meters. During welding, use a multimeter to measure whether the output voltage reaches more than 220V. For welding fittings over 200, a six-square-millimeter cable must be used. For more than 50 meters, a ten-square-millimeter cable must be used. For fittings over 315, a 380V power supply is recommended to prevent poor welding and unnecessary losses.

4. After welding, pressurize according to the pressure rating of the pipes and fittings. During pressurization, an air vent must be installed every 50 meters to ensure that the pressurized air can be discharged normally.

5. After welding, pressurize before backfilling to avoid unnecessary losses.

Pressurization should be divided into three steps: first, water injection; second, pressure increase and air discharge; third, when the pressure reaches three kilograms, pause for three minutes and then inject water to ensure

6. There is no air in the pipe, and then normal pressurization is carried out until the standard pressure of the pipes and fittings is reached. Maintaining pressure for more than six hours without pressure drop indicates that it is qualified.
