In building water distribution system, galvanized steel pipe has been over a hundred years glorious history and a variety of new plastic pipes and composite pipes have developed rapidly, but there are some deficiencies due to varying degrees, far from being able to fully meet the water supply pipe needs of the department and the state of drinking water and water quality requirements.

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 stability of spiral welded pipe thermal fatigue generally refers to the work in the cold, heat alternating the role of the ability to resist cracks, which is called thermal fatigue crack due to cold, heat alternating crack said. Limit of weld conditions.

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.

Consumption, high efficiency, welded structural steel pipe consumption process is simple. Types of specifications, equipment investment, but the average strength of less than seamless.

The material with which a pipe is manufactured is often the basis for choosing a pipe. Materials used for manufacturing pipes include:

In August, Guizhou Province, the sun is shining, the sky is clear, and it is the best time in Guizhou. In order to enhance team cohesion, promote communication among team members, and enrich the spare time of employees, Yupeng Steel and Iron Co., Ltd. organized the "2023 Annual Tourism Guizhou 4-day tour" activity

Double submerged arc welded straight seam steel pipe is a new welding method invented in 1940, it is the same place and the front of the manual welding it or slag protection, but this residue is not the electrode coating, but melting out welding flux. Flux system consists of a funnel filled with flux transported through a pipeline to the front to be welded.

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.

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 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.

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.
