Zhejiang anti-corrosion steel pipe manufacturer wholesale supply of Hangzhou, Huzhou, Jiaxing, Shaoxing, Zhoushan, Ningbo, Jinhua, Quzhou, Taizhou and Lishui, Wenzhou around the pipe corrosion, anti-corrosion steel pipe, desulfurization pipelines, power plants corrosion resistant pipes, acid and alkali liquid pipelines, tank corrosion. Li 135-2345-6O22 lined pipe corrosion (corrosion lined pipe) is the viscosity average molecular weight of linear structures 25O million or more polyethylene (PE), due to its high molecular weight, having a corrosion resistant rubber lined pipe damage, impact-resistant, corrosion-resistant, self-lubricating, excellent overall performance, called "amazing plastic", but the molding process more difficult. In recent years, pushing the plunger, single-screw extrusion technology breakthroughs, so that can be achieved with plastic pipe corrosion pipe industrialized continuous production. The pipe has the following advantages of a high corrosion resistant rubber lined pipe lined pipe corrosion resistance minimum coefficient of friction, combined with ultra-high molecular chain particularly long, so corrosion resistant rubber lined steel pipe corrosion resistance in transport all kinds of slurry pipelines body than when steel pipe, stainless steel tube 4-7 times higher. Shanghai Chemical Industry Research Institute "Research into the plastic tube wear test report" pointed out: the following four different pipe materials in the same diameter, flow rate, test materials, the concentration of the test conditions, the results are: glass fiber reinforced polypropylene tubes average Thickness of wear 11.5424mm / years; engineering grade polypropylene tube (PP) 13.5828mm / years; corrosion steel pipe (UHMW-PE) 5.O1O4mm / years; steel (A3) 36.2424mm / years; experimental results show that the corrosion lined Pipeline (UHMW-PE) pipes of pipeline corrosion resistant rubber lined steel pipe (A3) of seven times. 2, superior tensile strength and high impact resistance plastic-lined pipe corrosion pipeline is PE8O 2.5 times the tensile strength, PElOO 2 times, while its resistance to environmental stress cracking is the OO P cited 1 times , and the fatigue resistance is PElOO 3O times. So the pressure pipe anti-corrosion and anti-environmental destruction capabilities far beyond normal polyethylene pipe. Lined pipe corrosion, impact resistance and absorb impact energy in the first ranks of plastic, whether it is strong external shocks or internal pressure fluctuations are difficult to make it crack. Its impact strength of nylon 66 1O times, PVC 2O times PE of 4 times. Especially at low temperatures, but higher impact strength values. Lined pipe corrosion such flexibility for the delivery system provides a safe and reliable protection. 3, anti-corrosive pipe corrosion lined pipe has excellent resistance to chemicals * sex, in addition to strong oxidizing acid, in a certain range of temperature and concentration ability of various corrosive media (acids, bases, salts) and organic media ( except for naphthalene solvent), and in 2O ℃ 8O 8O ℃ in organic solvents impregnated 3Od, the appearance of any anomaly, other physical properties are almost unchanged 4, no scaling lined pipe corrosion resistance and non-stick self-lubricating With resistance, friction coefficient minimum. Special process produces pipe wall corrosion resistance, abrasion resistance, no scaling, so the flow resistance is small, can be maintained long-term velocity and flow unabated. Designed to reduce the inner diameter of 15.4% than steel. This feature is used for the power plant fly ash system has great significance. In crude oil, mud and other pipelines is also very suitable.
