Seamless steel pipe is now used in a wide range of fields, such as in the construction, transportation and so on, the reason why seamless steel pipe can be so many use, must be the advantages and advantages of the steel pipe itself. Compared with the general steel pipe used, seamless steel pipe adopts a series of high-tech manufacturing technology, and then has the excellent quality of seamless steel pipe.

Everyone is familiar with welded pipes. What is the difference between seamless steel pipe and welded pipe?

First of all: the most important thing is that their molding process is different. Ordinary steel pipes, such as tap water pipes, are generally welded by bending flat plates. This process is relatively simple and rough, and a weld can be found on the finished product after processing. Seamless steel pipe is generally the molten steel through the annular slit backlog and then by stretching and other processing processes, in this process there is no weld.

In terms of performance, the pressure bearing capacity of seamless steel pipe is greatly improved than that of ordinary steel pipe, so it is often used in high pressure equipment. Such as the pipeline connection of hydraulic equipment. The weld of ordinary steel pipe is its weak link, and the weld quality is also the main factor affecting its overall performance.

What are the uses of seamless steel pipes?

What are the uses of seamless steel pipes?

Due to the strong bending capacity of steel pipes, in recent years, steel pipes have been used in the roof frames, beams, columns, etc. of buildings such as factories and venues. For example: Beijing stadium buildings, Chengdu, Shanghai, Shenyang and other airport terminal buildings. China's domestic and international standards of production of high-quality carbon structural steel, low-alloy structural steel, alloy structural steel, stainless steel and other grades of seamless steel pipe in the development of the national economy and improve people's living standards play an increasingly important role.

How to improve the production technology of precision steel pipe

Key skills in the production of high-performance corrosion-resistant steel. Discuss the corrosion mechanism of steel in different corrosive environments, and use functions and comment methods (marine corrosion, acid environment oil and gas corrosion, atmospheric corrosion, wear-resistant corrosion, etc.); According to the data planning method of product life cycle concept, the skills of corrosion-resistant steel alloy composition planning, exercise, continuous casting, control rolling and cooling, welding, mechanical processing, etc. are discussed to form the common sense property rights of corrosion-resistant steel data system of China's precision steel pipes.

When it comes to seamless steel pipe, the first thing that comes to mind is that the quality of this pipe (Conduit) material is superior, which is the characteristic of seamless steel pipe. Secondly, the seamless steel pipe adopts the structure of steel (Structure), so the hardness (Hardness) of seamless steel pipe is very high. Seamless steel pipe is to make the molten metal and iron substrate reaction to produce alloy layer, so that the substrate and the plating layer are combined. Hot galvanizing is to pickle the steel pipe first, in order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot dip plating tank. Hot galvanizing has the advantages of uniform coating, strong adhesion and long service life. The quality of seamless steel pipe is the reason why this pipe material can be promoted and developed in the industrial field (domain), which is determined by the complex production (Produce) process (production engineering) of seamless steel pipe. The characteristic of seamless steel pipe is that there is no joint in the wall part, while the ordinary pipe has obvious joints.

What factors affect the performance of heat exchanger seamless steel tube?

What factors affect the performance of heat exchanger seamless steel tube?

Material selection: The material selection of the seamless steel pipe of the heat exchanger is an important factor affecting the performance. Common materials are carbon steel, alloy steel, stainless steel and so on. Different materials have different chemical compositions and mechanical properties. For different working conditions and media, it is necessary to select suitable materials to ensure performance.
