High-density polyethylene jacket 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.

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. 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. 

Calculated as follows:
OD ≤ 400mm, the upper and lower deviation, and = 0.1 × of the nominal wall thickness of +0.2
Diameter ≥ 400mm, the upper and lower deviation = 0.15 × the sum of the nominal wall thickness of +0.2

Anti-corrosion steel pipe

Anti-corrosion steel pipe is processed through the preservation process, which can effectively prevent or slow down the process in the transport and use of chemical or electrochemical corrosion reaction of steel pipe.

Sunny Steel Internal and External Anti-corrosion steel pipe services: Anti-corrosion steel pipe in the country is mainly used for petroleum, chemical, gas, heat, sewage treatment, water, bridges, steel pipes and other engineering fields.anti-corrosion steel pipe is divided into the following categories:

IPN8710 Water pipe inner wall
When the corrosion of steel in more types of media, such as acids, alkalis, salts, oxidants and water vapor, etc., the coating must be chemically inert, acid salt corrosion, the coating should be compact structure, water permeability, adhesion, tough fullness. Such cases for IPN8710 corrosion.
IPN8710 anti-corrosion primer: from polyurethane, polyethylene, modified epoxy resin, non-toxic anti-corrosion pigments, additives and other components, room temperature curing to form interpenetrating networks, dense coating structure, acid, alkali, salt, rust performance, strong adhesion for water supply pipeline wall corrosion primer paint. IPN8710 anti-corrosion finish: from the epoxy, rubber, resin-modified, non-toxic anti-corrosion pigments, additives and other components. Excellent chemical resistance, non-toxic, anti-microbial corrosion, corrosion protection for water supply pipeline wall finish.

FBE epoxy powder corrosion
FBE epoxy powder anti-corrosion structure: electrostatic spraying the surface of the steel epoxy powder coating, a film. The coating has a coating operation is simple, clean, coating impact resistance and bending properties, temperature resistance advantages.

3PE / 2PE steel pipe 
2PE/3PE corrosion structure: the surface of the steel and epoxy powder electrostatic spraying adhesive side wound, lateral wound polyethylene coating, combined with the excellent performance of the three, thus significantly improving the overall quality of pipeline corrosion. Resistant to chemical corrosion, resistance to cathodic disbondment resistance, mechanical damage to properties.

Coal tar epoxy anticorrosive
Coal tar epoxy anticorrosive structure: from the epoxy resin + filler made of coal tar pitch + anti-corrosion coatings on steel surface coated with glass cloth to strengthen the formation of a coating, commonly used in the pipe wall corrosion. Thickness of 0.5 ~ 1.0mm.

High-density polyethylene jacket corrosion
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. 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.
