The future market prospect of stainless steel forged flanges of flange manufacturers is good

2022/09/30

There are three types of forged flange sealing surfaces for flange manufacturers: flat sealing surface, suitable for low-pressure non-toxic media; concave-convex sealing surface, suitable for slightly higher pressure; tongue-and-groove sealing surface suitable for flammable, explosive and toxic media and high pressure occasions.

The stainless steel forged flange of the flange manufacturer is the darling of the water industry. These devices rely on the support of components such as stainless steel flanges to provide people with better services. China has accelerated its urbanization process. The western development and residential construction projects promulgated by the state are inseparable from the support of stainless steel flange manufacturers, which drives the demand of stainless steel flange manufacturers in the construction industry. People's awareness of environmental protection has increased. At the same time, stainless steel flanges can be better applied. At present, stainless steel flanges have attracted people's attention because of their hygienic, environmental protection, economical and other characteristics, and have been introduced into applications such as drinking water systems and heating systems.

It is inseparable from the treatment devices of industrial waste gas, garbage and sewage. It has the advantage of being resistant to corrosion, so it is more widely used than other metals. In the process of promoting green environmental protection in my country, stainless steel pipe fittings have developed rapidly. With the continuous advancement of my country's environmental protection industry, stainless steel pipe fittings are growing at an average annual rate of 15%. Such a huge demand for stainless steel pipe fittings will stimulate the development of the stainless steel pipe fittings industry at the same time, providing more business opportunities for more stainless steel manufacturers.

What problems exist in the processing of stainless steel flanges by flange manufacturers and how to solve them?

Weld defects: The welding defects of stainless steel flanges of flange manufacturers are serious. If it is compensated by manual and mechanical grinding, the grinding marks will cause uneven surface and affect the appearance; uneven grinding, polishing and passivation: pickling and passivation treatment should be carried out after manual grinding and polishing. For workpieces with large area, it is difficult to achieve uniform processing effect, and the ideal uniform surface cannot be obtained. It also has its disadvantages, such as high labor cost and high cost of auxiliary materials;

Difficult to remove scratches: The overall pickling passivation will cause chemical corrosion or electrochemical corrosion and rust in the presence of corrosive media, and impurities such as carbon steel and spatter adhering to the surface of stainless steel from scratches and welding spatter cannot be removed;

How to solve the stainless steel flange processing problem of flange manufacturers?

1. Select blanking and enter the next process after completion. Different stainless steel workpieces enter the corresponding process according to the processing requirements;

2. When bending, the tools and grooves used for bending should be determined according to the drawing size and the thickness of the 304 stainless steel seamless steel pipe. Avoiding the collision and deformation of the product and the tool is the key to the selection of the upper die (in the same product, different types of upper dies can be used), and the selection of the lower die should be determined according to the thickness of the sheet.

3. In order to weld firmly, a bump is punched on the workpiece to be welded, so that the bump is evenly contacted with the plate before electrified welding to ensure consistent heating at each point. At the same time, the welding position can also be determined. Soldering is necessary. Adjust the preload time, hold time, maintenance time and rest time to ensure that the workpiece is spot welded firmly.
