Welcome to Hebei million gold piping, large caliber anti-corrosion pipe insulation [quality], anti-corrosion pipe insulation provided by the Hebei billion gold piping. We are Hebei billion gold Pipe Manufacturing Co., Ltd. (www.yijinguanjian.com) here: Hebei Cangzhou specializes in: insulation joints, insulating flange, flanges, elbows, head, tee, head, Stone, for anti- 3PE anti-corrosion steel pipe to enhance the quality of related facilities Introduction The article, I 3PE anti-corrosion steel pipe manufacturers combined with our years of experience and access to massive material published literature I 3PE anti-corrosion steel for enhancing the quality of different topics related facilities Introduction insightful. 3PE coating obeyed impact factor, or more like the layout of each process with the selection, quality and heating the outside, painting temperature, cooling, transmission accuracy, material forming and testing, discipline is not good resulting in coating adhesion force is small, too thin, cracking or bubbles abuse, kind of job fulfillment and scientific standards for correctional facilities abuse, the rate of corrosion control products to ensure commensurate important. Let's take a look at for the quality of the three PE corrosion-related facilities, of which domestic enacted released a steel outer annular cooling effect of the cooling device has been progress, but as before reluctantly pedicle threat from the external cooling system leads to quality facilities abuse and bead coating thickness thinning. Pointed out that the ideal facility soar coating thickness thinning is cooled from inside the pipe. U.S. secretly an internal cooling pipe coating facility, the facility inside the pipe into the pump, sprinkler pipe to pipe wall in the transition process, and the cooling pipe coating flashbacks as: steel, FBE layer, adhesive layer and the PE layer . 3PE anti-corrosion steel pipe heat insulation speed steel prices, steel and coating enables rapid cooling, since the cooling process while the coating is from the inside out, coating the wall during the cooling contraction and better anti-corrosion pipe insulation adhesive, hoop stress corrosion layer is small, the weld bead coating very slight thinning, thereby improving the quality and reduce the cost of raw materials corrosion. But this internal cooling facilities to achieve greater difficulty. Three-layer structure of PE pipe corrosion: a first powder layer of epoxy (FBE> 100um), the second adhesive layer (AD) 170 ~ 250um, a third layer of polyethylene (PE) 2.5 ~ 3.7mm. Three materials integrated large-caliber anti-corrosion pipe insulation quality, and with the steel firm to form an excellent coating. Diameter range Φ60 ~ Φ1420, wall thickness range between 2.5-18mm, which is quite good antiseptic method, generally up to 50 years of life, not only to extend the underground pipeline equipment replacement cycle, and significant cost savings for national construction provides a strong role! 3PE antisepsis antiseptic method is the most commonly used, in addition to 2PE, 2PP, 3PP, their manufacturing process is almost, but not the same raw material, which is characterized by the production of anti-corrosion process is simple, good corrosion effect, low prices, the pipe manufacturing antiseptic methods generally accepted industry!
