The processing method of stainless steel flange

What is the processing method of stainless steel flange?

Stainless steel flange has the best pressure resistance, temperature and pressure resistance, good flexibility and heat resistance, and the product advantages are greatly superior to other plastic pipes. Stainless steel flange fittings are easy to install, good thermal conductivity and suitable for floor heating system. Flange fittings have excellent impact strength, hot melt welding and mechanical connection, better than PB-PP-R thermal conductivity. First, let us and stainless steel flange manufacturers together to preheat, analysis of the processing method of stainless steel flange.

Stainless steel flange fittings are made of steel plate. After the steel plate is cut according to the requirements, like UOE forming, it is also punched into a circle by the die. There are two halves and then they are put together and welded. After the push, the flange should be shaped in this thermal state. After finishing the shape, the outer diameter and wall thickness of flange fittings meet the requirements. Next, the finishing process is carried out. After shot peening, the oxidation sheet on the inside and outside surface of the flange fittings is removed, and the two ends are bevelled to facilitate welding. After inspection, steel word, spraying paint, packaging and other processes, you can leave the factory.

Stainless steel flange pipe fittings have two more procedures of flaw detection and heat treatment than other pipe fittings. The other procedures are the same. Because some flanges are not handled properly, they will be distorted, which is not allowed. In addition, after pushing the head is generally the front end of the outer diameter is large, to be reshaped through the plastic mold. Nondestructive testing is required because of the presence of the weld. Due to the existence of welding stress, it is necessary to conduct heat treatment.

Stainless steel flange processing methods are also many. Many also belong to the category of mechanical processing, the most used is stamping method, forging method, roller processing method, rolling method, bulging method, stretching method, bending method, and combined processing method.

Stainless steel flange process explanation:

Roller method: A core check valve is placed in the tube and pushed by a roller around the outer edge of the valve, which is used for round edge processing.

Rolling method: generally do not use mandrel, suitable for thick wall tube inside round edge.

Bulging method: one is to place rubber in the tube, above the punch compression, so that the tube protrudes into shape; Another method is hydraulic bulge forming, in which a liquid is filled in the middle of the pipe and the pressure of the liquid is used to bulge the pipe into the desired shape. This method is used in the production of bellows, as we commonly use.

Forging method: The end or part of the tube is extended by the type forging machine to reduce the outer diameter of the electric butterfly valve. The commonly used type forging machine includes rotary type, connecting rod type and roller type.
