1. Generally, large-diameter thin-walled steel pipes are used for the transportation of generally low-pressure fluids such as water, gas, air, oil, and heating steam.
2. Ordinary carbon steel wire casing (GB3640-88) is a steel pipe used to protect wires in electrical installation projects such as industrial and civil buildings, and installation of machinery and equipment.
3. Large-diameter thin-walled steel pipes are steel pipes with welds parallel to the longitudinal direction of the steel pipe. Usually divided into metric electric welded pipes, electric welded thin-walled steel pipes, transformer cooling oil pipes, etc.
4. Spiral seam submerged arc welded pipes for pressure fluid transportation (SY5036-83) are hot-rolled steel strip coils as pipe blanks, spirally formed at room temperature, welded by double-sided submerged arc welding, and spiral seam steel pipes for pressure fluid transportation. The steel pipe has strong pressure-bearing capacity and good welding performance. It has undergone various rigorous scientific inspections and tests and is safe and reliable to use. The steel pipe has a large diameter, high transportation efficiency, and can save investment in laying pipelines. Mainly used for pipelines for transporting oil and natural gas.
5. Large-diameter thin-walled steel pipe spiral seam high-frequency welded pipe for pressure fluid transportation (SY5038-83) is made of hot-rolled steel strip coil as pipe blank, spirally formed at room temperature, welded by high-frequency lap welding, and used for pressure fluid transportation. The steel pipe has strong pressure bearing capacity, good plasticity, and is easy to weld and process; after various strict and scientific inspections and tests, it is safe and reliable to use, the steel pipe has a large diameter, high transportation efficiency, and can save investment in laying pipelines. It is mainly used for laying pipelines for transporting oil, natural gas, etc.
6. Spiral seam submerged arc welded steel pipe for general low-pressure fluid transportation (SY5037-83) is made of hot-rolled steel strip coil as pipe blank, spirally formed at room temperature, and made of double-sided automatic submerged arc welding or single-sided welding method. It is used for water, gas, air steam, and other general low-pressure fluid transportation. Submerged arc welded steel pipe.
