Introduction of the mainstream production technology of stainless steel pipe in the world

In recent years, the rapid development of production technology and equipment technology level of global stainless steel pipe, stainless steel pipe international advanced production features is the use of new equipment, new technology, automatic control and NDT to improve product quality and yield, in the domestic stainless steel welded pipe and seamless steel pipe production technology […]

Production process and characteristics of stainless steel seamless pipe and welded pipe

There are two main types of stainless steel pipes, which are stainless steel seamless pipes and stainless steel welded pipes. It is known by the name that the former has no weld seam, the latter is mainly welded and formed, and their specific production process differences and their respective characteristics are described below. Stainless steel seamless pipe The stainless […]

Two forms and application examples of stainless steel welded pipe

Stainless steel welded pipe is a pipe made of stainless steel plate or strip crimping after forming and welding, simple production process efficiency, low cost and variety of specifications, but generally low strength than seamless steel pipe. However, with the continuous progress of production technology, the quality of stainless steel welded pipe is getting better and […]

Advantages and disadvantages of surface treatment process for stainless steel pipelines

In order to enhance the surface quality of stainless steel pipelines, optimization of the surface morphology and application of structure, reduce the energy level and the number of dielectric layers, need to do some processing on stainless steel pipeline system, mainly divided into mechanical drawing, mechanical grinding, polishing, pickling and passivation, feather cloth light burning blunt, […]

Strength difference of various kinds of stainless steel materials

The strength of stainless steel is affected by various factors, and the most important and basic is the chemical elements added to the chemical composition. Therefore, the strength of the ferrite, martensite and austenitic stainless steel is different because of the differences in their chemical composition. Martensitic stainless steel has the characteristics of hardening by quenching, so […]

Reasons and preventive measures for magnetic properties of austenitic stainless steel in cold processing

It is well known that the vast majority of stainless steel materials are suitable for cold forming. Austenitic stainless steel itself is not magnetic, but cold processed austenitic stainless steel will have strong magnetic properties, especially those made of austenitic stainless steel, such as head, elbow and so….. Why will the austenitic stainless steel suddenly appear to […]

The reason for the performance of stainless steel pipes in refining furnace are stronger than that of medium frequency furnace

At present, there are mainly two kinds of stainless steel pipes smelting furnaces on the market. They are mainly refining furnaces and intermediate frequency furnaces. The quality of stainless steel pipes produced by them is obviously different, and the stainless steel pipes produced by refining furnaces are superior in performance. What is the refining furnace? Refining under […]

Performance comparison of stainless steel welded pipe with polished welded pipe

At present, industrial stainless steel welded pipe is widely used in the application market of stainless steel at home and abroad. Among them, because of the difference of surface processing technology, the stainless steel industrial welded pipe is mainly divided into two kinds of welded pipe and polished welded pipe. The following are the principles and advantages […]
