HDPE pipe

High-density polyethylene jacket tube is widely used in oil pipelines, gas pipelines, urban heating pipes, water pipes, electricity and other corrosion engineering, product quality and service by the users of a good level.

HDPE (High-density polyethylene jacket pipe)

HDPE pipe ideal suitable for many different applications, including municipal, industrial, energy, geothermal, landfill and so on. HDPE pipe strength, durability, flexibility, weight of light welding after the high density polyethylene to zero leakage rate, because the welding process formed a whole HDPE system.

High-density polyethylene tubing is relatively environmentally friendly because it is non-toxic, corrosion-resistant and chemical-resistant, has long design life, and because of the flexibility, the deletion is suitable for the trench-free installation method.

Manufacture of stent should be added antioxidants, UV stabilizers and carbon black, etc. Polyethylene jacket tube easy to aging, such as open storage tarpaulin and other items appropriate to cover, dumps should stay away from high heat and fire, anti-corrosion steel pipe made after the ban exposure, sudden cold, or polyethylene jacket tube easy to crack, the impact product performance and service life.

The thired party, SGS, BV, can be accepted.

Certificate: Certificate: API 5L, API 5CT. ISO 9001; CE and so on.
Resistant to chemical corrosion, resistance to cathodic disbondment resistance, mechanical damage to properties.

HDPE lined steel pipe

HDPE lined steel pipe slightly larger than the outer diameter of tube technology is the main channel diameter HDPE liner, after necking, making cross-section smaller than the cross-sectional area of the main channel, in the role of traction quickly insert the main channel.

HDPE Lined Pipe Fittings

HDPE Lined Pipe Fittings, and short straight sections of steel pipe are often needed to terminate the pipeline, or for use in areas where larger radius bends cannot be accommodated.

The steel pipe spools, or fittings, are fabricated with weld neck flanges to connect with the HDPE-lined steel pipeline.

Seal Flange Connection

Seal Connection for these more demanding applications:

  • High Pressure
  • High Temperature
  • Abrasive Flow Wear
  • Dual Containment Seal

Seal flange connections utilizes multiple self-energized seals and are designed to ASME B16.5 up to Class 2500 rating.

High Density Polyethylene (HDPE) Jacketed System

High Density Polyethylene (HDPE) Jacketed System is designed for piping systems above or below ground suitable for inside or outside applications. High quality polyurethane foam insulation combined with a durable watertight jacket supplied in 20' or 40' lengths, means an economical, high-quality system.

High density polyethylene jacket corrosion structure: the outer surface of pipe wrapped in high-density polyethylene material, with a high mechanical strength and excellent corrosion resistance, can protect the steel in the transportation, installation and use of the process to avoid external factors the damage.



Weled steel pipe specification, Standard and identification

Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding.

Galvanized pipe process characteristics

What is Galvanized Steel Pipe? Galvanized steel can be made into a strong plumbing or tubing material -- one that resists corrosion from exposure to water or the elements. It has been used used for water-supply pipes or as a strong tubing for outdoor applications.
