Makati420 staiSignificant. As for the combined welding of steel pipes with high-frequency preheating, the weld quality is equivalent to the conventional argon arc welding and plasma welding. The welding operation is complex and the whole welding is easy to complete automation. This combination is easy to connect with the existing high-frequency welding equipment, with low investment cost and good benefits.
Increase at the same time. Because austenitic series stainless steel pipes have MS point (martensite start temperature or martensite formation temperature) at low temperature (subzreo temperature), martensite can be formed when it is kept below MS point. Martensite formation at low temperature makes austenite series stainless
Shiro.100 times of unit weight iron loss value + 100 times of thickness value. For example, dr510-50 indicates that the iron loss value is 0.5mm thick hot-rolled silicon steel plate. The brand of hot-rolled silicon steel sheet for household appliances is expressed by jdr+ iron loss value + thickness value, such as jdr540-50.
Because the stainless steel pipes have good outer diameter, mechanical properties, acid and alkali resistance and corrosion resistance, the stainless steel pipes and stainless steel pipe manufacturers are generally the anti-corrosion materials or hardware products used by large-scale chemical production enterprises with strict outer diameter and wall thickness requirements
.Of course, the above is only common for coloring stainless steel plates. There are other popular ones. Welcome to leave a message!
In this process, the following key points should be paid attention to: during the welding process the correct included angle should be maintained between the welding handle, welding wire and weldment, and the ideal rake angle of the welding handle nozzle is 70 DEG& Mdash; 80°, The included angle between the welding wire and the surface of the weldment is 15 DEG& Mdash; 20°; Correct weld pool temperature and change welding
2. Raw materials of stainless steel pipes. If the hardness is too low, it is not easy to polish (BQ is not good). If the hardness is too low, orange peel is easy to appear on the surface during deep drawing affecting BQ performance. BQ with high hardness is relatively good.
Any steel with hollow section with openings at both ends and a large ratio between its length and section perimeter can be called steel pipe. When the length is smaller than the section perimeter, it can be called pipe section or tubular fittings, which belong to the category of pipe products.
Line grinding reflector for decoration according to the purpose bridge steel plate boiler steel plate shipbuilding steel plate armored steel plate automobile steel plate roof steel plate structural steel plate electrical steel plate (silicon steel sheet) spring steel plate solar special plate (Hairui
It is divided into two steps, one is pretreatment, and the second step is ash removal.
Service first.Molten salt has strong oxidizing power, low melting point and small viscosity. In the production process, only the sodium halo content is not less than 8% (WT). It shall be treated in a salt bath furnace at 450 ~ 470 ℃ for 5 minutes for ferritic stainless steel and 30 minutes for austenitic stainless steel. Again,
There are several ways to clean stainless steel plate at ordinary times: washing with warm water; Organic solvent washing; Neutral detergent cleaning.
Significant. As for the combined welding of steel pipes with high-frequency preheating, and the whole welding is easy to complete automation. This combination is easy to connect with the existing high-frequency welding equipment, with low investment cost and good benefits.
A proper amount of MnSO4 was added with CrO3 and H 2SO 4H2O as the main components 4H2O coloring solution was used for chemical coloring of stainless steel industrial pipe. The effects of pretreatment process, coloring solution temperature, mass concentration and coloring time on the color film of stainless steel industrial pipe were discussed.
Total quality assurance.Whether 310S stainless steel plate will rust or not mainly depends on the environment. Secondly, it is divided into several models from low to high
The product surface quality after polishing by the polishing machine meets the design requirements, and can be applied to the surface treatment of precision tubes used in aerospace, medicine, military industry and other fields. Aiming at the defect characteristics of stainless steel tube blank, such as insufficient cleanliness, perforation crack, skin, rolling surface crack, etc
For important threading pipes, special thread connection is adopted). For some special pipes, in order to make up for the impact of thread on the strength of pipe end, pipe end thickening (internal thickening, external thickening or internal and external thickening) is usually carried out before threading.

As we know, there are different types of stainless steel plates. Different types of stainless steel plates are used in different scenarios. It mainly depends on the carbon, manganese, nickel, chromium and other aspects to distinguish whether the stainless steel plate is 201 or 304.
If rust is found on the surface of stainless steel plate, the surface can be brushed with stainless steel plate wax. This product is specially used for rust prevention treatment of stainless steel. After a period of time, polish, polish and clean the wax, and then clean the wax on the surface
