The production of wear-resistant plastic alloy composite pipe mainly goes through the following processes:
First, the production of outer wall steel pipe: the production of outer wall steel pipe shall go through blanking, welding, rust removal and other processes, and can enter the next process only after passing the inspection;
Second, the production of lined plastic alloy steel pipes: the production of lined plastic alloy pipes will go through a series of processes such as batching, processing, granulation, feeding, mixing, extrusion, vacuum shaping, spray cooling, traction cutting, etc. to produce plastic alloy pipes. After passing the inspection, the next process can be started;
Third, the outer wall steel pipes and wear-resistant plastic alloy pipes that have passed the acceptance are now formed into plastic alloy composite wear-resistant pipes through reducing lining pipes, flanging and other processes. The plastic alloy pipe is closely combined with the outer wall steel pipe, and then subjected to anti-corrosion treatment and painting. Plastic alloy composite pipes can only be packaged and delivered after passing the acceptance.
The wear-resistant plastic alloy composite pipe is based on the wear-resistant plastic alloy as the inner lining, supplemented by reinforced steel pipes. This product combines the wear-resistant, corrosion-resistant and aging resistance of the inner lining and the high strength and toughness of the outer layer. It is suitable for working conditions with severe wear and corrosion.

1, High wear resistance
The wear resistance of HCHNMPE wear-resistant plastic alloy ranks first among the existing plastics. The mortar wear test proves that it is 4 times more wear-resistant than nylon, and several times more wear-resistant than carbon steel, brass and other metals. Its service life is significantly improved.
2, High impact resistance
The impact strength of HCHNMPE wear-resistant plastic alloy ranks first among the existing plastics, and it is difficult to crack it whether it is subjected to external strong impact or internal pressure fluctuation. The impact strength is quite high even at - 70 ºC. Its flexibility provides a safe and reliable guarantee for the conveying system.
3, Aging resistance
The main factors affecting weather resistance are the type, number and relative molecular weight of unsaturated genes in the molecular chain. The less unsaturated genes in the molecular chain, especially trans hypovinylidene and vinylidene, the greater the relative molecular weight, the better the weather resistance. Hchnmpe has stable properties, strong weather resistance and good aging resistance. The weather resistance under natural storage is 50 years (the performance will decrease by 10% after 50 years).
4, Corrosion resistance
HCHNMPE is a saturated molecular group structure with high chemical stability. It can resist various corrosive media and organic solvents within a certain temperature and concentration range. Therefore, it is unnecessary to apply anti-corrosion coatings during construction.
5, Self lubrication
HCHNMPE wear-resistant plastic alloy has low surface adsorption, good self lubrication and non adhesion, small friction coefficient, small flow resistance, and can save energy by more than 30%. The flow of HCHPE plastic alloy is 30% larger than that of steel pipe, so you can choose plastic alloy pipe with smaller diameter under the same flow conditions.
6, High pressure bearing
HCHNMPE wear-resistant plastic alloy composite pipe can withstand high pressure, up to 25Mpa.
7, Convenient connection
HCHNMPE wear-resistant plastic alloy composite pipe is generally connected by flange, and can be connected by quick coupling according to design requirements.

1. What is your mode of transportation?
Answer: Shipping, shipping
2. Why is your price higher than others?
Answer: Because the quality of the products must be guaranteed, the raw materials we use are all of high quality and strictly controlled. We cannot achieve the lowest price, but we will ensure that the quality is passed. So there will be differences in prices. The quality of raw materials differs greatly in price.
3. Can it be made in strict accordance with the caliber, specification and length provided by me?
Answer: General conventional products are implemented according to standard specifications, and non-conventional products can be customized.
4. I have a large demand, can I offer a discount?
Answer: Yes, depending on your specific needs, large quantities can be discounted.
