1. Welded steel pipe for low-pressure fluid transportation is also called general welded pipe, commonly known as black pipe. It is a welded steel pipe for conveying general low pressure fluids such as water, gas, air, oil and heating steam and other purposes. The thickness of the steel pipe is divided into ordinary steel pipe and thick steel pipe. The pipe end form is divided into non-threaded steel pipe and threaded steel pipe. The specification of the steel pipe is expressed by the nominal diameter (mm), and the nominal diameter is an approximate value of the inner diameter. The welded steel pipe for low-pressure fluid transportation is mainly used as a raw pipe for galvanized welded steel pipe for low-pressure fluid transportation, in addition to being directly used for conveying fluid.
2. Galvanized welded steel pipe for low pressure fluid transportation is also called galvanized electric welded steel pipe, commonly known as white pipe. It is used for conveying water, gas, air, oil, steam, warm water, etc.
3. Common carbon steel wire casing is a steel tube used to protect electric wires in industrial and civil buildings, installation machinery and equipment and other electrical installation projects.
4. Straight seam electric welded steel pipe is a steel pipe whose weld is parallel to the longitudinal direction of the steel pipe. Usually divided into metric electric welded steel pipe, welded thin-walled pipe, transformer cooling oil pipe and so on.
5. Spiral submerged arc welded pipe for high-pressure fluid transportation is a spiral steel pipe which is used for high-pressure fluid transportation, which is made of hot-rolled steel coil as tube blank, subjected to normal temperature spiral forming and welded by double-sided submerged arc welding. The steel pipe has strong pressure bearing capacity and good welding performance. It is safe and reliable after various strict scientific tests . The steel pipe has a large caliber and high conveying efficiency. Mainly used to transport oil and natural gas.
6. The spiral welded pipe for pile is made of hot-rolled steel coil as tube blank, which is often spiral formed by double-sided submerged arc welding or high-frequency welding. It is used for steel pipes for civil engineering structures, wharfs, bridges and other foundation piles.
