tpe防腐螺旋钢管价格/920x15螺旋缝埋弧焊钢管
现在螺旋钢管的常用标准一般分为:SY/T5037-2000(部标、也叫 普通流体输送管道用螺旋缝埋弧焊钢管)、GB/T9711.1-1997(国标、也叫石油天然气工业输送钢管交货技术条件第一部分:A级钢管(到目前要求严格的有GB/T9711.2 B级钢管))、API-5L(美国石油协会、也叫管线钢管;其中分为PSL1和PSL2两个级别)、SY/T5040-92(桩用螺旋缝埋弧焊钢管)
节后螺旋钢管现货钢价持续上涨,且涨幅扩大,但因下游未完全开工,故钢市实际成交未全部放量。建筑钢市场价格涨幅较明显,主流规格螺纹钢均价周环比大幅上涨130元/吨。目前商家对节后螺旋钢管终端需求预期乐观,带动现货钢价上涨,但实际成交一般。板材市场上总体价格上升。主流规格热扎板卷均价周环比上涨66元/吨;中厚板均价周环比上涨101元/吨。因螺旋钢管钢厂库存相对较少,故多数积极挺价,而螺旋钢管社会库存却相对偏高,部分商家或为出货小幅降价。
