The connection of stainless steel flat welded flange is an important connection method for pipeline construction, and the connection between the connecting pipe and the connecting pipe plays an important effect and value.
Stainless steel flat welded flange connection is the two pipes, pipe fittings or devices, first fixed on a flange, between the two flanges, plus flange pad, bolted together to complete the connection. Some pipe fittings and devices now come with flanges, which are also attributed to flange connection.
Introduction to the use of stainless steel flat welding flange
Stainless steel flat welded flanges differ from other flanges in two obvious characteristics Stainless steel flat welded flanges are used in pipeline installations. Stainless steel flat welding flange connection is the two pipes, pipe fittings or devices, first fixed on a flange, between the two flanges, plus flange pad, bolted together.
Some pipe fittings and devices now come with flanges, which are also attributed to flange connection. It now includes traditional stainless steel flat welded flanges and high pressure self-tightening flanges.
Disadvantages of stainless steel flat welded flange
The planning disadvantage of stainless steel flat welded flange is that it cannot be leak-free. This is the lack of planning: the linkage is dynamic
And such as thermal expansion and fluctuating periodic load will form the movement between the flange faces, affecting the function of the flange, so that the integrity of the flange is damaged, and eventually lead to leakage.
Any product may not have shortcomings, just try to control the lack of products to a minimum, so in the production of stainless steel flat welded flange as far as possible to improve the function of the product, so that it can play a large effect.
Stainless steel flat welding flange product function
The Al2O3 content in the ceramic layer lining of the ceramic composite steel pipe is greater than 95%, and the microhardness is HV1000-1500, so it has more than ten times higher than the quenched carbon steel, which is better than tungsten drill carbide. The chemical function is stable, has excellent corrosion resistance and acid resistance, can resist various inorganic acids, its corrosion resistance is more than ten times that of stainless steel.
Stainless steel flat welded flange refers to a flange connected with a container or pipeline by a fillet weld. It is an arbitrary flange. According to the integrity of the connection between the flange ring and the straight barrel section, the design is checked according to the integral or loose flange. There are two kinds of flange rings with neck and without neck.
Compared with the neck butt welded flange, the stainless steel flat welded flange has simple structure and less material, but the tightness and sealing are not as good as the neck butt welded flange. Stainless steel flat welded flange is widely used in the connection of medium and low pressure vessels and pipelines.
