The cause of the deformation of rectangular tube welding

In the welding deformation theory, we can know that the large size of the weld will led to the greater deformation, welding the same size, the welding heat input on large, can lead to large deformation, the long seam welding, welding deformation will be small, asymmetrical seam or asymmetrical arrangement of the welding seam deviation will cause more serious to severe deformation.
The Use of Welded Steel Pipe or Application Range

General Pipe: Average welded steel pipe used to transport low pressure fluid. With Q195A, Q215A, Q235A steel. Easy welding may also be used in other soft steel. Pipe to carry water pressure, bending, flattening and other experiments, there are certain requirements for surface quality, delivery is usually a length of 4-10m, often required length (or double length) delivery.
Steel pipe jet vortex quenching technology

In the steel manufacturing process, like a important uses for steel products, such as oil well pipes, boiler tubes, etc., are needed most hardened in order to obtain the desired mechanical properties. Cooling as a key link hardened steel heat treated for production efficiency, product quality and economic efficiency ultimately have a significant impact.
Uneven wall thickness of steel pipe

Steel tube wall thickness is not same, may on the cross section and longitudinal tube body wall thickness range phenomenon exists objectively, which is called the uneven wall thickness. To control this heterogeneity, in some steel standard provides a uniform wall thickness to allow indicators, the general requirement does not exceed 80% of the wall thickness tolerances.
The Type of Stainless Steel

There are different types of stainless steels: when nickel is added, for instance, the austenite structure of iron is stabilized. This crystal structure makes such steels virtually non-magnetic and less brittle at low temperatures. For greater hardness and strength, more carbon is added. With proper heat treatment, these steels are used for such products as razor blades, cutlery, and tools.
Piping and Plumbing Fitting - Material

The material with which a pipe is manufactured is often the basis for choosing a pipe. Materials used for manufacturing pipes include:
Welded Steel Pipe and Flammable Vapors

When using steel pipe tools, we might as well avoid frequent contact with skin and eyes. In case of contact, flush with plenty of water should not last long since if irritation persists, welded steel pipe might be eroded. The beveled pipe end helps spread the solvent easily as the welded steel pipe is joined to the fitting.
What are the Uses of Carbon Steel?

Carbon steel is a metal alloy that combines iron and carbon. The various uses of carbon steel depend on the amount of carbon added to the alloy; for instance, carbon steel with the lowest amount of carbon is called wrought iron and is used for things like fencing. Medium-carbon steel, also called mild steel, is the type of steel that is used for structural purposes in buildings and bridges.
Welded steel pipe forming method

Welded steel pipe is the use of different types of steel through the process of shaping the way the bending process and so welded pipe products for a class, however, because the type of welded steel pipe market is very diverse, so the molding method is also very diverse, welding the main pipe forming method under which workers have several types.
Types of steel pipes

Steel pipe is a hollow, a large number for a pipe conveying fluid, such as oil, gas, water, gas, steam, etc., engaged in bending, torsional strength, lighter weight, so it is widely used in the manufacture of mechanical parts and engineering structures.
The Purpose Guidance Of Welded Steel Pipe

Generally speaking, the welded steel pipes are divided into general welded pipe, galvanized welded pipe, oxygen welding tube, metric system welded tube, transformer tube, welding thin wall pipe and spiral welded pipe etc.
The Application and Analysis of Welded Steel Pipe in Different Industries

Welded steel pipe market requirement is based on the basic industries, such as the oil industry, the chemical industry and the power generation industry. The consumption of these basic industries occupies two thirds of the total consumption.
