包层焊接耐腐蚀钢板 日本住友金属公司生产了一种包层焊接耐腐蚀钢管,适用于石油和化工等部门输送有腐蚀的液体和气体。 这种钢管的内壁为不锈钢或高镍合金,外面包有普通钢层。利用这种普通钢管输送腐蚀性气体和液体,要比用全不锈钢管或高镍合金管经济得多。外径有50至1500毫米多种规格。 生产这种钢管的工艺流程是:
Clad welding corrosion-resistant steel Sumitomo Metal Co., Ltd. produced a cladding corrosion-resistant steel pipe for oil and chemical and other departments to transport corrosive liquids and gases. The inner wall of this steel pipe is made of stainless steel or high-nickel alloy and covered with ordinary steel. It is much more economical to transport corrosive gases and liquids using this type of steel than with a full stainless steel tube or a high-nickel alloy tube. Outer diameter of 50 to 1500 mm variety of specifications. The production process of this steel pipe is:
