厚壁无缝管-
输送用无缝钢管；锅炉用无缝钢管；锅炉用高压无缝钢管；化肥设备用高压无缝钢管；地质砖探用无缝钢管；石油砖探用无缝钢管；石油裂化用无缝钢管；船舶用无缝钢管；冷拔冷轧精密无缝钢管；各种合金管。
无缝钢管表示方法为外径，壁厚，厚壁无缝钢管主要用于机械加工，煤矿，液压钢等多种用途。厚壁无缝钢管的材质分为10#、20#、35#、45#、16Mn、27SiMn、12Cr1MoV、10CrMo910、15CrMo、35CrMo等。
厚壁无缝钢管分类——热轧厚壁无缝钢管、冷轧厚壁无缝钢管、冷拔厚壁无缝钢管、挤压厚壁无缝钢管、顶管
钢管重量计算公式:[(外径-壁厚)*壁厚]*0.02466=kg/米(每米的重量)
厚壁无缝管不锈钢理论重量计算公式:（外径-壁厚）×壁厚×0.02491=KG/M（每米的重量）
厚壁无缝管合金钢理论重量计算公式:（外径-壁厚）×壁厚×0.02486=KG/M（每米的重量）
