螺旋焊管的定义及分类标准

给大家讲解一下螺旋焊管的知识,基本可以分为下面四个方面:1、螺旋焊管的特点:直缝焊管生产工艺简单,生产效率高,成本低,发展较快。螺旋焊管的强度一般比直缝焊管高,能用较窄的坯料生产管径较大的焊管,还可以用同样宽度的坯料生产管径不同的焊管。但是与相同长度的直缝管相比,焊缝长度增加30~100%,而且生产速度较低。因此,较小口径的焊管大都采用直缝焊,大口径焊管则大多采用螺旋焊

To explain the knowledge of spiral welded pipe can be divided into the following four aspects: 1. The characteristics of spiral welded pipe: straight welded pipe production process is simple, high production efficiency, low cost, rapid development. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe. It can be produced with narrow blank with larger pipe diameter. It can also be produced with the same width of blank with different pipe diameter. However, compared with the straight seam pipe of the same length, the weld length is increased by 30~100% and the production speed is low. Therefore, small diameter welded pipes are mostly welded longitudinally, while large diameter welded pipes are mostly spiral welded.

2、螺旋焊管及其标准分类:承压流体输送用螺旋缝埋弧焊钢管(SY5036-83)主要用于输送石油、天然气的管线;承压流体输送用螺旋缝高频焊钢管(SY5038-83),用高频搭接焊法焊接的,用于承压流体输送的螺旋缝高频焊钢管。钢管承压能力强,塑性好,便于焊接和加工成型;一般低压流体输送用螺旋缝埋弧焊钢管(SY5037-83),采用双面自动埋弧焊或单面焊法制成的用于水、煤气、空气和蒸汽等一般低压流体输送用埋弧焊钢管

2. Spiral welded pipes and their standard classification: Spiral seam submerged arc welded pipes (SY5036-83) for pressurized fluid transportation are mainly used for oil and natural gas pipelines; Spiral seam high frequency welded pipes (SY5038-83) for pressurized fluid transportation are used for spiral seam high frequency welded pipes (SY5038-83), which are welded by high frequency overlap welding method and used for pressurized fluid transportation. The steel pipe has strong bearing capacity, good plasticity, and is easy to be welded and processed; the spiral seam submerged arc welded steel pipe (SY5037-83) for low pressure fluid conveying, which is made by double-sided automatic submerged arc welding or single-sided welding, is used for water, gas, air and steam conveying.

3、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)、API-5L(美国石油协会、也叫管线钢管)、SY/T5040-92(桩用螺旋缝埋弧焊钢管)

3. The common standards of spiral steel pipe are generally divided into: SY/T5037-2000 (Department Standard, also known as ordinary fluid pipeline SSAW pipe), GB/T9711.1-1997 (National Standard, also known as oil and gas industry pipe delivery technical conditions Part 1: A steel pipe), API-5L (American Petroleum Association, also known as pipeline pipe) SY/T5040-92 (spiral SSAW pipe for pile)

4、螺旋管材质:Q235A,Q23b,0Cr13、1Cr17、00Cr19Ni11、1Cr18Ni9、0Cr18Ni11Nb. Q345 L245 L290 X42 X46 X70 X80

4. Spiral tube material: Q235A, Q23b, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni11Nb. Q345 L245 L290 X42 X46 X70 X80
