Advantages of Anti-Corrosion Pipes

Long service life polyethylene pipe has the highest molecular weight, good stability and aging resistance. Under normal working temperature and pressure conditions, the service life can be guaranteed for more than 50 years;

Corrosion resistance the molecular structure of polyethylene is extremely stable, resistant to chemical corrosion such as natural gas, liquefied petroleum gas, and artificial gas, and does not require secondary anti-corrosion equipment. The chemical substances in the soil will not cause any degradation to the pipe;

Good flexibility polyethylene pipe is a kind of pipe with high toughness, and its elongation at break exceeds 500%. The flexibility of polyethylene tubing makes it easy to bend. In engineering, obstacles can be bypassed by changing the direction of the pipeline. In many cases, the flexibility of the pipeline can reduce the amount of pipe fittings and reduce installation costs;

Excellent impact resistance and earthquake resistance. The low-temperature embrittlement temperature of polyethylene is extremely low, and it can be used safely in the temperature range of -60 ° c ~ 60 ° c. It has a very strong adaptability to uneven settlement of pipe foundations. During winter construction, due to the good impact resistance of the material, there will be no brittle cracking of the pipe;

Good wear resistance test shows that the wear resistance of polyethylene pipe is 4 times that of steel pipe, especially in the field of mud transportation, compared with steel pipe, polyethylene pipe has better wear resistance;

The polyethylene pipe with small water flow resistance has a smooth inner surface and its manning coefficient is 0.009. The smooth inner surface and non-adhesive properties ensure that polyethylene pipes have a higher conveying capacity than traditional pipes, and also reduce the pressure loss of the pipeline and the energy consumption of water delivery;

Good environmental protection performance polyethylene pipes do not add heavy metal stabilizers during processing, and the material is non-toxic and harmless. It is a green and environmentally friendly pipe material, and the polyethylene material itself can be recycled and will not pollute the environment;

Good flame retardant and antistatic properties. Our company has specially developed flame retardant and antistatic polyethylene pipes, which are suitable for specific places such as flammable and explosive;

Safe and reliable connection method polyethylene pipes are mainly connected by hot melting or electrofusion, which essentially maintains the identity of the interface material and structure with the pipe body itself, and realizes the integration of joints and pipes. It can effectively resist the hoop stress and axial tension stress caused by internal pressure, and there is no worry about water leakage or air leakage;

Lightweight, easy to handle, and easy to construct. The specific gravity of polyethylene pipes is only 1/8 of that of steel pipes. It is easy to handle and bend, and the welding process is simple and fast. The comprehensive cost of the project is low, and it has significant economic benefits.

Types of Anti-Corrosion Pipes

IPN8710 corrosion

● In a variety of media, such as acid, alkali, salt, oxidizing agent and water vapor, etc., the coating of the steel pipe will have a chemical inert and easy to corrosion. So the coating should compensate for water permeability, adhesion, toughness and fullness. For this type of corrosion protection should be used IPN8710. IPN8710 anti-corrosion primer is composed of polyurethane, polyethylene, modified epoxy resin, non-toxic anti-corrosion pigments, additives and other components. Curing at room temperature will form a dense coating structure. IPN8710 anti-corrosion primer with anti rust properties, has excellent chemical reaction performance and a good protective effect on the inner wall of the pipeline.

● FBE epoxy powder anti-corrosion structure: Steel epoxy powder coatings form a layer of film on the surface of line pipe. The coating has the advantages of simple operation, cleaning, temperature resistance, impact resistance and bending properties.

2PE/3PE corrosion

● 2PE/3PE corrosion structure: In the side of the steel and epoxy powder electrostatic spray coating, lateral wound polyethylene coating. Combining with a variety of excellent performance, the coating significantly improves the comprehensive quality of the pipeline corrosion.

Coal tar epoxy anti-corrosive

● Coal tar epoxy anti-corrosive structure: Filler made from coal tar pitch, adding epoxy resin and anti-corrosion coatings on steel surface, commonly used in the pipe wall corrosion. The thickness of that is between 0.5 and 1.0mm.

High-density polyethylene jacket corrosion

● High density polyethylene jacket corrosion structure: The outer surface of the tube is wrapped in high density polyethylene material, which has high mechanical strength and good corrosion resistance. In the transport, the material protect the steel very well and the use of the process avoid damage from the external factors.
