厚壁无缝钢管

厚壁无缝钢管:生产工艺可分为冷拔、冷轧、热轧、热胀四种基本方法。钢管的材质有10#、20#、35#、45#，称为普通钢管。分为无缝钢管结构;运输用无缝钢管;锅炉用无缝钢管;锅炉用高压无缝钢管;施肥设备用高压无缝钢管;地质砖勘探用无缝钢管;石油砖勘探用无缝钢管;石油裂解用无缝钢管; seamless steel pipes for ships; cold-drawn cold-rolled precision seamless steel pipes; various alloy pipes. Seamless steel pipes are represented by outer diameter and wall thickness. Thick-walled seamless steel pipes are mainly used for mechanical processing, coal mines, hydraulic steel and other purposes.
