螺旋钢管
Spiral steel pipe
螺旋钢管的常用标准一般分为:SY/T5037-2008(部标、也叫 普通流体输送管道用螺旋缝埋弧焊钢管)、GB/T9711.1-2008(国标、也叫石油天然气工业输送钢管交货技术条件部分:A级钢管(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/T5040-2008(桩用螺旋焊缝钢管)。
The commonly used standards of spiral steel pipe are generally divided into: SY / t5037-2008 (ministry standard, also known as spiral submerged arc welded steel pipe for ordinary fluid transmission pipeline), GB / t9711.1-2008 (national standard, also known as technical delivery conditions for steel pipe for oil and natural gas industry). Part I: Grade a steel pipe (GB / t9711.2 is strictly required Api-5l (American Petroleum Institute, also known as pipeline steel pipe; which is divided into PSL1 and PSL2), SY / t5040-2008 (spiral welded steel pipe for pile).

直缝钢管
ERW pipe 
直缝钢管执行的标准GB/T3091-2008低压流体钢管生产标准,GB/T9711.1-2 -1997石油天然气钢管生产使用标准,还可以执行美国API 5L 管线钢管执行标准。生产材质:Q195A-Q345E;245R;Q345QA-D;L245-L485;X42-X70。承压参数主要有2ST/T ,S为屈服强度,T为壁厚。埋弧焊已经发展成为,有双丝埋弧焊,还有多丝埋弧焊,效率更进一步提高。
The standard for straight seam steel pipe is GB / t3091-2008 production standard for low-pressure fluid steel pipe, GB / t9711.1-2-1997 production and use standard for oil and gas pipe, and American API 5L pipeline steel pipe executive standard. Production materials: q195a-q345e; 245r; q345qa-d; l245-l485; x42-x70. The main bearing parameters are 2st / T, s is yield strength, t is wall thickness. Submerged arc welding has developed into double wire submerged arc welding and multi wire submerged arc welding, and the efficiency is further improved.

无缝钢管是用10、20、30、35、45等优质碳结钢16Mn、5MnV等低合金结构钢或40Cr、30CrMnSi、45Mn2、40MnB等合结钢热轧或冷轧制成的。10、20等低碳钢制造的无缝管主要用于流体输送管道。45、40Cr等中碳钢制成的无缝管用来制造机械零件,如汽车、拖拉机的受力零件。一般用无缝钢管要保证强度和压扁试验。热轧钢管以热轧状态或热处理状态交货;冷轧以热处理状态交货。
Seamless steel pipe is made of 10, 20, 30, 35, 45 and other high-quality carbon Bonded Steel 16Mn, 5mnv and other low-alloy structural steel, or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other composite steel. 10. The seamless pipe made of 20 grade low carbon steel is mainly used for fluid transportation pipeline. The seamless pipe made of 45, 40Cr and other medium carbon steel is used to manufacture mechanical parts, such as the stressed parts of automobile and tractor. Generally, the strength and flattening test of seamless steel pipe shall be ensured. Hot rolled steel pipes are delivered as hot rolled or heat treated; cold rolled pipes are delivered in heat treated condition.
