内衬不锈钢复合钢管执行城镇建设行业标准CJ/T192-2004,是在钢管内壁复合薄壁不锈钢管,这种双金属复合钢管大大提高钢管在输水、输热水、输煤气、输天然气、输油过程中的耐腐蚀性能,表面光滑,流体阻力小,又保留了钢管机械强度高,可采用焊接、沟漕、螺纹连接,密封性好的优点,克服了镀锌钢管易腐蚀,采用热熔连接的塑料管易漏水和老化的缺陷,是输气、输水、输油钢管的升级换代的理想产品。现就接头的处理和焊接进行较深入研究,并佐以全面的理化和机械性能试验验证改进的合理性,得出了相应的、可行的结论。
Lined with stainless steel composite pipe to implement the urban construction industry standard CJ / T192-2004, is the thin-walled stainless steel composite wall in the pipe wall, this bimetal composite pipe greatly enhance the water pipe, water, gas, natural gas, Oil corrosion resistance during the process, the surface smooth, fluid resistance is small, but also retains the high mechanical strength of steel, welding, ditch, screw connection, good sealing advantages, to overcome the corrosion of galvanized steel, the use of hot-melt Leakage and aging of the connected plastic pipe defects, is the gas, water, oil pipe upgrade the ideal product. Now deal with the joint and welding more in-depth study, combined with a comprehensive physical and chemical properties and mechanical tests to verify the improvement of the reasonableness, come to the corresponding, feasible conclusions.
