Weight calculation formula and description of stainless steel seamless pipe

2025/06/05

There is a complete formula for calculating the weight of stainless steel seamless pipes, in which different materials correspond to different coefficients. You can save this article for future use.The weight calculation formula for stainless steel seamless pipes: Weight (kg) = (outer diameter-wall thickness × wall thickness × coefficient × length.In this formula, the outer diameter represents the···

What indicators are suitable for storage conditions of stainless steel seamless pipes?

2025/06/05

The storage of seamless stainless steel pipes is particular. It not only requires environmental control, but also requires the selection of appropriate storage sites and methods, as well as good packaging management and risk prevention and control!The control of the environment for seamless stainless steel pipes lies in humidity, relative humidity, chloride ion concentration and ventilation requir···

Causes and countermeasures of surface corrosion of stainless steel seamless pipes

2025/06/05

Although stainless steel seamless pipes are called stainless steel, they are not rust-free. When corrosion occurs on the surface, the main reason is rust or stress corrosion cracking.Rust may occur because of the use of stainless steel seamless pipes in corrosive environments (chloride ions), or because of the acid corrosion caused by the adhesion of oil/organic juice (such as noodle soup, vegetab···

Detailed introduction to the process flow of stainless steel seamless pipe

2025/06/05

Stainless steel seamless pipes have to peel several layers from ingot to finished product.First, heat the 304 and 316L stainless steel ingots to more than 1200 degrees to soften them, and then use a tapered roller piercing machine to punch out a hollow rough tube.The hot-rolled pipe is directly rolled on a three-roller oblique rolling mill, and the wall thickness can be reduced to more than 2.5mm,···

It turns out that stainless steel seamless pipes can be found everywhere!

2025/06/05

Stainless steel seamless pipe is a seamless "steel straw" that can be seen everywhere from chemical plants to nuclear power plants.In chemical plants, stainless steel seamless pipe is the leader, which can transport deadly liquids such as sulfuric acid and caustic soda.In oil pipelines, stainless steel seamless pipe is standard, and it can transport oil and gas underground, and it is as ···

How to detect the composition accuracy of stainless steel seamless pipes?

2025/06/05

Stainless steel seamless pipe is a high-pressure and corrosion-resistant pipe with strong integrity and no welds, which is manufactured by hot rolling/cold drawing. In terms of its process, hot rolling includes heating, perforating, rolling, etc. of round tube billets, which is suitable for large-diameter pipes; while cold drawing improves accuracy through annealing and pickling, and the wall thic···

What circumstances will cause the stainless steel seamless pipe to burst?

2025/06/05

Stainless steel seamless pipes will not burst under normal circumstances. The main reasons for their bursting are related to materials, processes, welding, and use.If the chemical composition of the stainless steel seamless pipe material is deviated, such as insufficient nickel and chromium content or excessive carbon content, the toughness of the seamless pipe will decrease, the hardness will inc···

How important is the skin condition of stainless steel seamless pipe?

2025/06/05

The skin state of the stainless steel seamless pipe is the surface state, which is very important for it and directly affects its durability and usage scenarios.First of all, it has its own anti-fouling film. There is a layer of chromium oxide film (similar to the anti-scratch coating of mobile phones) on the surface of the stainless steel seamless pipe that is invisible to the naked eye. When it ···

Why do stainless steel seamless pipes have internal cuts?

2025/06/05

The inner straight pipe in the production of stainless steel seamless pipe is a common defect of the automatic pipe rolling mill and a difficult problem to solve. In most cases, the straight path is small and will not turn the stainless steel seamless pipe into waste; but sometimes, when rolling aviation pipes and alloy stainless steel seamless pipes, this defect will cause great damage, so it sho···

What are the product characteristics of stainless steel seamless pipes?

2025/06/05

Stainless steel seamless pipe is a long steel strip with a hollow cross-section and no seams around it. The thicker the wall thickness of the product, the more economical and practical it is. The thinner the wall thickness, the higher its processing cost will be. So do you know what are the product characteristics of stainless steel seamless pipe?The product characteristics of stainless steel seam···
