1.普通碳素钢电线套管(GB3640-88)是工业与民用建筑、装置机器设备等电气装置工程中用于维护电线的钢管。

1. Common Carbon Steel Wire Bushing (GB3640-88) is a steel pipe used for maintenance of electric wires in industrial and civil buildings, installations, machinery and equipment and other electrical installations.

2.直缝电焊钢管(YB242-63)是焊缝与钢管纵向平行的钢管。通常分为公制电焊钢管、电焊薄壁管、变压器冷却油管等等。

2. Longitudinal welded steel pipe (YB242-63) is a steel pipe with longitudinal parallel weld and steel pipe. Usually it is divided into metric welded steel pipe, welded thin-walled pipe, transformer cooling oil pipe and so on.

3.承压流体保送用螺旋缝埋弧焊钢管(SY5036-83)是以热轧钢带卷作管坯,经常温螺旋成型,用双面埋弧焊法焊接,用于承压流体保送的螺旋缝钢管。钢管承压才能强,焊接性能好,经过各种严厉的科学检验和测试,运用平安牢靠。钢管口径大,保送效率高,并可节约铺设管线的投资。主要用于保送石油、自然气的管线。

3. Spiral submerged arc welded pipe (SY5036-83) for pressure-bearing fluid delivery is a kind of spiral welded pipe, which is made of hot rolled steel strip coil and spirally formed at normal temperature and welded by double-sided submerged arc welding, and is used for pressure-bearing fluid delivery. The steel pipe has strong bearing capacity and good welding performance. After various strict scientific tests and tests, it is safe and reliable to use. The steel pipe has large diameter, high delivery efficiency and saves investment in laying pipelines. Mainly used for oil and natural gas pipelines.

4.承压流体保送用螺旋缝高频焊钢管(SY5038-83)是以热轧钢带卷作管坯,经常温螺旋成型,采用高频搭接焊法焊接的,用于承压流体保送的螺旋缝高频焊钢管。钢管承压才能强,塑性好,便于焊接和加工成型;经过各种严厉和科学检验和测试,运用平安牢靠,钢管口径大,保送效率高,并可俭省铺设管线的投资。主要用于铺设保送石油、自然气等的管线。

4. The SY5038-83 spiral seam high frequency welded steel pipe for pressure fluid delivery is a high frequency spiral seam high frequency welded steel pipe for pressure fluid delivery, which is formed by hot rolled steel strip coil and is welded by high frequency lap welding at normal temperature. The steel pipe can bear pressure, has good plasticity, and is easy to weld and process. After various rigorous and scientific tests and tests, it is safe and reliable to use, has large diameter of steel pipe, high efficiency of delivery, and saves investment in laying pipelines. It is mainly used for laying pipelines for guaranteeing oil and natural gas.

5.普通低压流体保送用螺旋缝埋弧焊钢管(SY5037-83)是以热轧钢带卷作管坯,经常温螺旋成型,采用双面自动埋弧焊或单面焊法制成的用于水、煤气、空气和蒸汽等普通低压流体保送用埋弧焊钢管。

5. Spiral submerged arc welded pipe (SY5037-83) for ordinary low-pressure fluid delivery is a submerged arc welded pipe for water, gas, air and steam, which is made of hot-rolled steel strip coil as billet and is spirally formed at normal temperature and is manufactured by double-sided automatic submerged arc welding or single-sided welding.

6.普通低压流体保送用螺旋缝高频焊钢管(SY5039-83)是以热轧钢带卷作管坯,经常温螺旋成型,采用高频搭接焊法焊接用于普通低压流体保送用螺旋缝高频焊钢管。

6. The SY5039-83 spiral seam high frequency welded steel pipe for ordinary low pressure fluid delivery is made of hot rolled steel strip coil and spirally formed at normal temperature. The high frequency lap welding method is used to weld spiral seam high frequency welded steel pipe for ordinary low pressure fluid delivery.

7.桩用螺旋焊缝钢管(SY5040-83)是以热轧钢带卷作管坯,经常温螺旋成型,采用双面埋弧焊接或高频焊接制成的,用于土木建筑构造、码头、桥梁等根底桩

7. Spiral welded steel pipe for piles (SY5040-83) is made of hot rolled steel strip coil as billet, spirally formed at normal temperature, double-sided submerged arc welding or high frequency welding. It is used in civil construction, wharf, bridge and other foundation piles.
