Welded pipe production lineIt is a process in which the material (the same or different) of the welding part is combined with the atom to form a connection by heating or pressurizing or both, with or without filling material. Then, how to compare different welded pipe production line standards.
1. Generally, welded tubes are used to transport fluids, such as water, gas, air, oil, and heated steam, at generally low pressures.
2. Ordinary carbon steel wire casing is a steel pipe used to protect wires in industrial and civil construction, mechanical equipment installation and other electrical installation projects.
3. Longitudinal welded pipe is a kind of steel pipe whose weld is parallel to the longitudinal direction of the steel pipe. It is usually divided into metric welded pipe, welded thin-walled pipe, transformer cooling oil pipe, etc.
4. Spiral seam submerged arc welded pipe for pressure fluid transportation is a spiral seam steel pipe for pressure fluid transportation, which is formed by hot-rolled steel strip coil as pipe blank, spiral forming at normal temperature and double-sided submerged arc welding. The steel pipe has strong pressure bearing capacity and good welding performance. It has passed various strict scientific inspections and tests and is safe and reliable to use. The steel pipe has a large diameter and high conveying efficiency, which can save the investment in laying pipelines. Mainly used for transportation of oil and natural gas pipeline.
5. The spiral seam high-frequency welded pipe for pressurized fluid transportation is a kind of spiral seam high-frequency welded steel pipe for pressurized fluid transportation. It is formed by hot-rolled steel coil as pipe blank, spiral forming at normal temperature and high-frequency lap welding. The steel pipe has strong bearing capacity and good plasticity, which is convenient for welding and processing. After various strict scientific inspections and tests, it is safe and reliable to use, with large steel pipe diameter and high transportation efficiency, which can save investment in laying pipelines. It is mainly used for laying pipelines for transporting oil and natural gas.
6. Submerged arc welded steel pipes for general low-pressure fluid transportation are water, gas, air, steam and other general low-pressure fluid transportation submerged arc welded steel pipes. Hot-rolled steel coils are used as pipe blanks, spiral forming at room temperature, and automatic submerged arc welding on both sides or single-sided Welding.
What are other welded pipes?
1. Straight seam pipe
It is made of steel plate or steel strip after bending and welding. According to the weld form is divided into straight seam welded pipe and spiral welded pipe. According to the purpose, it is divided into ordinary welded pipe, galvanized welded pipe, oxygen blowing welded pipe, wire casing, metric welded pipe, inert pipe, deep well pump pipe, automobile pipe, transformer pipe, welded thin-walled pipe, welded special-shaped pipe, spiral welded pipe.
2. Ordinary welded pipe
Welded pipe is generally used to transport low pressure fluid. It can also be made of other low carbon steels that are easy to weld. Water pressure, steel pipe bending, flattening and other experiments have certain requirements for surface quality. Usually the delivery length is 4-10m, often need to be fixed length (or times long) delivery. The specification of welded pipe is expressed in nominal diameter (mm or inch). The nominal diameter is different from the actual diameter. According to the specified wall thickness, welded pipe has two kinds of ordinary steel pipe and thick steel pipe. According to the end shape of the steel pipe, the steel pipe is divided into threaded steel pipe and non-threaded steel pipe.
