The Introduction of Welded Steel Tube (Section Two)
Sep 06, 2018
In this article, I’d like to go on talking about the welded steel tube.
3. The ordinary carbon steel wire casing (GB3640-88) is the steel tube used for protecting the wire in industrial and civil construction and installation of machinery and equipment.
4. The straight seam welded steel pipe (YB242-63) is the steel pipe that the weld is parallel to the longitudinal steel pipe. Usually divided into metric welded steel pipe, welded thin-wall tube, transformer cooling pipe and so on.
5. The spiral seam submerged arc welding steel pipe (SY5036-83) which is used for fluid conveying is a hot rolled steel coil tube billet, and it is often spiral shaped with double-sided submerged arc welding method, spiral seam steel pipe used for pressurized fluid conveying. Steel tube with great loading capacity, good welding performance, and through strict scientific inspection and testing, the use of it is safe and reliable. The diameter of the steel pipe is big with high transmission efficiency, and can save laying pipelines. Mainly used for conveying oil, natural gas pipeline.
6. The high frequency welding steel pipe spiral seam (SY5038-83) is used for fluid conveying which is made of hot rolled steel coil tube billet, and formed by spiral method, using high-frequency welded lap welding method. Used in pressurized fluid conveying spiral seam high frequency welding steel pipe. Steel tube with great loading capacity and good plasticity is easy to welding and processing molding; After all kinds of strict and scientific inspection and testing, the use of it is safe and reliable, and the steel pipe diameter is big with high transmission efficiency, and laying pipelines of investment can be saved. It is mainly used for laying of pipeline transport oil, gas, etc.
7. The spiral seam submerged arc welding steel pipe (SY5037-83) used for low-pressure fluid conveying is made of hot rolled steel coil tube billet, and formed by spiral method, and it is the submerged arc welding steel pipe adopts the method of double automatic submerged arc welding or single side welding, which is used for conveying water, gas, air and steam.
8. The spiral seam high frequency welding (SY5039-83) is general used for low-pressure fluid transport, and it is made of the hot-rolled steel strip,and formed by spiral method, and the spiral seam high frequency welding steel pipe used for low-pressure fluid adopts high frequency overlap welding method.
9. The spiral weld pipe (SY5040-83) is a hot rolled steel coil tube billet, and formed by spiral method, made of double-sided submerged arc welding or high frequency welding, and it is used in civil construction structure, port, bridge foundation pile with steel pipe.
