Processing technology of super duplex stainless steel welded pipe

Because the offshore oil platform riser has long suffered the wave scour, it is necessary to have high strength and excellent resistance to point corrosion material. In all kinds of alternative materials, because super duplex stainless steel possesses austenite and ferrite structure at the same time, it has many advantages such as high corrosion resistance, […]

Introduction of annealing pickling process for new cold-rolled stainless steel plate

According to the relevant european standards, the conventional cold rolled stainless steel plate has two kinds of surfaces, one is the 2D/2B surface, the other is the surface after cold rolling, annealing, pickling and leveling. The second one is the 2R surface, which is cold rolled and annealed after smooth annealing. Before welding, clean up the paint, […]

Introduction of two installation methods of stainless steel pipe fittings

Stainless steel pipe fittings in the installation, there are two ways are the viega profi-press and the groove, and they have their own advantages, including stainless steel viega profi-press pipe is an upgraded version of the stainless steel pipe fittings, compared with the ordinary stainless steel pipe fittings, the installation is very easy. Its working principle […]

Analysis of common quality problems of stainless steel pipe fittings

Now stainless steel pipe fittings are widely used in all kinds of pipeline projects, especially for the three way, elbow and size head. The main reason is that the stainless steel pipe has good forming, strong pressure resistance and easy welding, which can effectively guarantee the pressure bearing capacity of the pipeline. Therefore, in pipeline engineering, especially […]

Problems and solutions to the use of bending equipment of stainless steel elbows

The main problem of large stainless steel pipe bending equipment is that the chute can’t move along with the stainless steel pipe, it is difficult to process, and the material is relatively wasteful. For these problems, the following is the improvement plan. Metal forming elbow is a very important part in the production process of the manufacturing, […]

What is the influence of the surface roughness of the stainless steel plate

It is well known that the surface quality roughness of the stainless steel plate will affect the effect of the finished product, so what are the effects of the roughness? Stainless steel plate surface has a layer of dense oxide film can prevent oxidation of stainless steel material erosion surface, which could effectively avoid oxidation, whereas a […]
