3pe anticorrosive steel pipe manufacturers offer

States on relevant measures and methods to improve the quality of 3PE anti-corrosion steel Hebei Pu Hao Industry Co., Ltd (www.360gangtie.com Business Manager: Gulian Jun Mobile: 13131798002 Tel: 0317-8377360 Fax: 0317-6189360 QQ: 2516871970 E-mail: 13131798002 @ 163 .com) is specialized in 2pe / 3pe anti-corrosion steel, polyethylene, anti-corrosion steel ipn8710 anti-corrosion steel, coal tar epoxy anti-corrosion steel, 2pe / 3pe enhanced levels of anti-corrosion steel, single double epoxy powder anti-corrosion steel, 2PP / 3PP anti-corrosion steel R & D, design, production and sale of cement mortar lining anti-corrosion steel products as one of the major manufacturers, wholesale manufacturers, suppliers to the spot. Reasonable price, timely quotes. Stakeholders in the industry are aware of the current factors that affect the performance of 3PE anti-corrosion steel layer is still more, like each process layout, equipment selection, surface quality, heating, painting temperature, cooling, transmission accuracy, material properties and testing, poor control will result in a small coating adhesion, too thin, cracks or bubbles and other defects, strict implementation of norms and working methods of scientific control deficiencies and ensure yield corrosion pipe to close important. 3PE anti-corrosion steel corrosion on quality, countries all have different ways in which our patent CN200710057236 [1] .9 (a water cooling pipe coating method) discloses a steel outer annular cooling device, the cooling effect is improved, but still can not overcome the external cooling measures resulting from quality defects and bead coating thickness decreases radically. [2] pointed out that the ideal way to reduce the thickness of the coating is cooled thinned from inside the pipe. US patents related US6270847B1 discloses a pipe coating internal cooling method within the pipe into the pump, water in the pipe to the pipe wall during rotation, steel pipe coating and cooling sequence is as follows: steel pipe, FBE layer, adhesive layer and the PE layer. Pipe heat transfer speed, steel pipe and coating allows rapid cooling, and because of the coating of the cooling process from the inside out, the coating in the cooling contraction and wall bonding better coating hoop stress is small , weld bead coating thinning is very small, and thus improve the corrosion quality and reduce raw material costs. However, this method difficult to achieve internal cooling. Above it is about China and the United States for its antiseptic quality 3PE anti-corrosion steel related research, and I hope we still have some help, and we will launch in the late associated method for improving the quality of corrosion on other countries, but also hope
