Spiral Welded Pipes Are Generally Used In Those Places

1. Welded steel pipe for low-pressure fluid transportation (GB/T3092-1993) is also called general welded pipe, commonly known as black pipe. It is a welded steel pipe used for conveying general lower 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 (light 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. It is customary to use inches, such as 11/2. 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.

1. Galvanized welded steel pipe for low pressure fluid transportation (GB/T3091-1993) is also called galvanized electric welded steel pipe, commonly known as white tube. It is a hot dip galvanizing (furnace welding or electric welding) steel pipe for transporting water, gas, air, oil, heating steam, warm water and other general lower pressure fluids or other purposes. The thickness of the steel pipe is divided into ordinary galvanized steel pipe and thick galvanized steel pipe; the connection end form is divided into non-thread galvanized steel pipe and threaded galvanized 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. It is customary to use inches, such as 11/2.
2. Ordinary carbon steel wire casing (GB3640-88) is a steel pipe used to protect electric wires in electrical installation projects such as industrial and civil construction, installation machinery and equipment.

4. Straight seam electric welded steel pipe (YB242-63) is a steel pipe whose weld is parallel to the longitudinal direction of the steel pipe. Usually divided into erw steel pipe, welded thin wall pipe, transformer cooling oil pipe and so on.

1. The pressurized fluid conveying (SY5036-83) is a spiral-slit steel pipe which is used for the conveying of pressurized fluid by hot-rolled steel strip coiling as tube blank, regular temperature spiral forming, and welding 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 and tests. The steel pipe has a large caliber, high conveying efficiency, and can save investment in laying pipelines. It is mainly used to transport oil and natural gas pipelines.
2. Confined fluid transport (SY5038-83) is a spiral welded pipe for hot-rolled steel strip coils, which is often formed by high-temperature lap welding and is used for pressurized fluid transport. The steel pipe has strong pressure bearing capacity and good plasticity, which is convenient for welding and processing. After various strict and scientific inspections and tests, the use is safe and reliable, the steel pipe has large caliber, high conveying efficiency, and can save investment in laying pipelines. It is mainly used for laying pipelines for transporting oil and natural gas.
3. General low-pressure fluid transport (SY5037-83) is a hot-rolled steel strip coil used as a tube blank, which is often spiral-formed by a double-sided automatic submerged arc welding or single-sided welding method for water, gas, air and Submerged arc welded steel pipe for general low pressure fluid transportation such as steam.
4. General low-pressure fluid transport (SY5039-83) is a hot-rolled steel strip coil used as a tube blank, which is often spiral-formed at a constant temperature, and is welded by a high-frequency lap welding method for a spiral welded pipe for general low-pressure fluid transportation.

9. SSAW steel pipe (SY5040-83) for piles is made of hot-rolled steel strip coils, often spiral-formed by double-sided submerged arc welding or high-frequency welding, used for civil engineering structures, wharfs and bridges. Steel pipes for foundation piles.

10. Galvanized welded steel pipe for low pressure fluid transportation (GB/T3091-1993) is also called galvanized electric welded steel pipe, commonly known as white tube. It is a hot dip galvanizing (furnace welding or electric welding) steel pipe for transporting water, gas, air, oil, heating steam, warm water and other general lower pressure fluids or other purposes. The thickness of the steel pipe is divided into ordinary galvanized steel pipe and thick galvanized steel pipe; the connection end form is divided into non-thread galvanized steel pipe and threaded galvanized 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. It is customary to use inches, such as 11/2. 11. Ordinary carbon steel wire bushing (GB3640-88) is a steel pipe used to protect electric wires in electrical installation engineering such as industrial and civil construction, installation machinery and equipment; straight seam electric welded steel pipe (YB242-63) is weld and steel pipe longitudinal Parallel steel pipes. Usually divided into metric electric welded steel pipe, welded thin-walled pipe, transformer cooling oil pipe, etc.

12. Confined fluid conveying (SY5036-83) is a spiral-slit steel pipe used for the conveyance of pressurized fluid by hot-rolled steel strip coiling as a tube blank, which is often spiral-formed at a constant temperature 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 and tests. The steel pipe has a large caliber, high conveying efficiency, and can save investment in laying pipelines. It is mainly used to transport oil and natural gas pipelines.
