“3pe anti-corrosion steel pipes are pipes (steel pipes) that are used in different working environments. In order to slow down or prevent pipes from being eroded and deteriorated by the chemical and electrochemical actions of external media or metabolic activities of microorganisms, two or three layers of polyethylene (3PE) are coated on their outer walls to achieve corrosion prevention of pipes. The service life of 3pe anti-corrosion pipes is extended by 3-5 times.”. Environmental Protection Group’s Impact on the Market and Manufacturers of Thick Wall 3PE Anticorrosive Steel Tubes Environmental Protection and Production Restriction Policy Supermarket Market expects that the price of Thick Wall 3PE Anticorrosive Steel Tubes and aluminum prices will be strongly boosted. The supply and demand of thick wall 3pe anti-corrosion steel pipes are improving, and the price of thick wall 3pe anti-corrosion steel pipes will continue to be optimistic in the second half of the year. “3pe anti-corrosion steel pipes may be in short supply due to environmental protection and limited production, and are expected to start rising in the fourth quarter and continue until the first half of next year.”. The recent increase in the price of thick wall 3PE corrosion resistant steel pipes is mainly related to the implementation of the production restriction plan in the northern heating season. In addition to the implementation of various inspections such as environmental protection supervision, banning “ground strip steel”, and safety production, market confidence has been boosted, with a stronger bullish attitude, and market growth has been increased. “Environmental inspectors are definitely good for the price of thick wall 3pe anti-corrosion steel pipes, after all, the release of production from manufacturers of thick wall 3pe anti-corrosion steel pipes that do not meet the requirements in the 3pe anti-corrosion steel pipe market will be restrained.” However, this year’s 3pe anti-corrosion steel pipe market is highly uncertain and needs to be adjusted at any time based on factors that change.
3PE anti-corrosion steel pipe structure: the first layer of epoxy powder (FBE ＞ 100um), the second layer of adhesive (copolymer adhesive) 170~250um, and the third layer of polyethylene (PE) 2.5~3.7mm. These three materials are tightly fused together and firmly combined with steel pipes to form an excellent anti-corrosion coating. 2PE anti-corrosion steel pipe: The pipe has a two-layer PE anti-corrosion structure, with the first layer of adhesive (AD) and the second layer of polyethylene (PE). The two materials are integrated, and the thickness of each layer is the same as that of the third layer of PE Thickness: 1.7-2.5 pipe diameter range Φ 60～ Φ 1420 Executive Standard: SY/T0413-2002 Advantages: 1. 3pe anti-corrosion steel pipe has good sealing performance, and long-term operation can greatly save energy, reduce costs, and protect the environment. 2. Strong corrosion resistance, simple and fast construction, with a service life of 30-50 years. 3. It also has good corrosion and impact resistance under low temperature conditions, with low water absorption of PE (less than 0.01%). 4. At the same time, it has high epoxy strength, low water absorption of PE, and good softness of hot melt adhesive, with high anti-corrosion reliability
