gb5310 high pressure boiler tube high-pressure boiler tube _ _ Chaohu three-source Trading

 Tianjin trimeric Source Trading Co., Ltd. is a professional engaged in electric power, petroleum, chemical, engineering, machining and other business support services for the integrated enterprise. GB13296-2007 (boiler, heat exchanger with stainless steel seamless pipe). Mainly used in chemical boiler, superheater, heat exchangers, condensers, catalytic tubes. Use of high temperature, high pressure, corrosion-resistant steel. The representative material for 0Cr18Ni9,1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti so on. GB / T14975-2002 (structure seamless steel pipe stainless steel). Mainly used for general structure (hotels, restaurants decoration) and the chemical industry's resistance to atmospheric mechanical structure, acid corrosion and has a certain strength of steel. The representative material for 0-3Cr13,0Cr18Ni9,1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti so on. API SPEC5CT-1999 (casing and tubing specification), the American Petroleum Institute (American Petreleum Instiute called "API") prepared and published all over the world-wide. Where: Casing: from the ground surface into his inner drilling gb5310 high pressure boiler tubes, as the wall lining the tube through which the pipe coupling connection between Tianjin trimeric Source Trading Co., Ltd. is a company specializing in electric power, petroleum, chemical , engineering, machining and other business support services for the integrated enterprise. Steel pipe or a variety of conventional weapons indispensable material, barrel, barrel, etc. to make steel. Different shapes steel pipe cross-sectional area can be divided into tube and shaped tubes. Because in the perimeter of equal conditions, the largest area of ??a circle with a circular tube can carry more fluid. In addition, the circular cross section to withstand internal or external radial pressure 13crmo44 high pressure boiler tube, the force is uniform, so the vast majority of pipe is pipe. Alloy tube into structures and high-pressure heat-resistant alloy seamless pipe. The main different from alloy tube production standards and industry, for quenched alloy tube annealing change its mechanical properties. Achieve the desired processing conditions. Its performance using a value higher than the average of seamless steel tubes and varied, the chemical composition of the alloy tube containing Cr more, high temperature, low temperature resistance, corrosion resistance. Carbon seamless alloy composition does not contain little or alloy component, palladium tube principle is purified hydrogen at 300-500 ℃, the hydrogen to be purified is passed into the tube side of palladium, the hydrogen is adsorbed on palladium the wall pressure boiler tubes, due to the lack of two palladium 4d electron shell electrons, which can generate an unstable chemical bonds with hydrogen (palladium and hydrogen such reaction is reversible), under the action of palladium, hydrogen is ionized to proton radius of 1.5 × 1015m, while palladium lattice constant of 3.88 × 10-10m (20 ℃ time), it can be through the palladium tube, under the action of palladium in combination with a proton and electron and re-formation of hydrogen molecules from the palladium the other side of the tube to escape. Palladium tube surface, not the dissociated gas impermeable, it is possible to obtain high purity hydrogen utilizing palladium tube. gb5310 high pressure boiler tube high-pressure boiler tube _ _ Chaohu trimer source of commerce provided by the Tianjin trimeric source Trading Company.
