Welded steel pipe, also known as welded pipe, is made of steel plate or steel belt after crimping forming welded steel pipe. Welded steel pipe production process is simple, high production efficiency, variety of specifications, less investment in equipment, but the general strength is lower than seamless steel pipe. Since the 1930s, with the rapid development of high quality strip rolling production and the progress of welding and inspection technology, the quality of weld is constantly improving, the variety and specifications of welded steel pipe are increasing day by day, and replaced the seamless steel pipe in more and more fields. Welded steel pipe is divided into straight seam welded pipe and spiral welded pipe according to the form of weld.
Straight seam welded pipe production process is simple, high production efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe, and the welded pipe with larger diameter can be produced with a narrower blank, and the welded pipe with different diameter can also be produced with a blank of the same width. But compared with the straight seam pipe of the same length, the weld length increases by 30~100%, and the production speed is lower. Therefore, small diameter welded pipe mostly use straight seam welding, large diameter welded pipe mostly use spiral welding.
Low pressure fluid transport welded steel pipe (GB/T3091-2008) is also known as general welded pipe, commonly known as black pipe. It is a welded steel pipe used for conveying water, gas, air, oil, heating steam and other general lower pressure fluids and other purposes. The wall thickness of steel pipe is divided into ordinary steel pipe and thickened steel pipe. Pipe end form is divided into non - rebar steel tube (light tube) and with rebar steel tube. The welded steel pipe used for low pressure fluid transportation is mainly used as the original pipe of galvanized welded steel pipe used for low pressure fluid transportation.
1. Galvanized welded steel pipe for low pressure fluid transportation (GB/T3091-2008), also known as galvanized electric welded steel pipe, commonly known as white pipe. It is a hot dip galvanized welded (furnace welding or electric welding) steel pipe used for conveying water, gas, air oil, heating steam, warm water and other general low pressure fluids or other purposes. The wall thickness of steel pipe is divided into ordinary galvanized steel pipe and thickened galvanized steel pipe. The end of the pipe is divided into galvanized steel pipe without thread and galvanized steel pipe with thread. Steel tube specifications are indicated by nominal diameter (mm), which is an approximation of the inner diameter. Traditionally, it is usually expressed in inches, such as 1/2, 3/4, 1, 2, etc.
2 Ordinary carbon steel wire bushing (YB/T5305-2006) is used to protect the wire in industrial and civil buildings, installation of machinery and equipment and other electrical installation projects.
3. Straight seam electric welded steel pipe (GB/T13793-2008) is a steel pipe with a longitudinal parallel seam to the steel pipe. Used for general structure, usually divided into metric welded steel pipe, welded thin-wall pipe and so on.
4. Spiral seam submerged arc welded steel pipe (SY/T5037-2000) for pressure fluid transportation is a spiral seam steel pipe used for pressure fluid transportation, which is made of hot rolled steel strip as tube blank, often formed at warm temperature and welded by double-sided submerged arc welding method. The steel pipe has strong bearing capacity and good welding performance. It is safe and reliable to use after all kinds of strict scientific inspection and testing. Large diameter steel pipe, high transmission efficiency, and can save the investment of pipeline laying. Mainly used for conveying oil and natural gas pipelines.
5. Spiral seam high frequency welded steel pipe for pressure fluid transportation (SY/T5038-2000) is a kind of spiral seam high frequency welded steel pipe used for pressure fluid transportation, which is made of hot rolled steel strip as tube blank, often warm spiral forming and welded by high frequency lap welding method. The steel pipe has strong bearing capacity and good plasticity, which is convenient for welding and processing. After all kinds of strict and scientific inspection and testing, the use of safe and reliable, large diameter steel pipe, high transmission efficiency, and can save the investment of pipeline laying. It is mainly used for laying pipelines for conveying oil and natural gas.
7. Spiral seam high-frequency welded steel pipe for general low-pressure fluid transportation (SY/T5039-2000) is a hot rolled steel strip as a tube billet, often warm spiral forming, using high frequency lap welding method welding spiral seam high-frequency welded steel pipe for general low-pressure fluid transportation.
8. Spiral welded steel pipe for pile (SY/T5768-2000) is made of hot rolled steel strip as tube blank, often warm spiral forming, double-sided submerged arc welding or high-frequency welding, used for civil construction structure, wharf, bridge and other foundation pile steel pipe.
