Processing Method of Stainless Steel Flange

Feb. 18, 2020

90°stainless steel elbow supplier to share with you: stainless steel flange fittings with the best pressure resistance, temperature and pressure resistance, good flexibility, heat resistance, product advantages are greatly superior to other plastic pipes. Stainless steel flange pipe fittings are easy to install and have good thermal conductivity and are suitable for floor heating systems. Flange fittings have excellent impact strength, can be hot-melt welded and mechanically connected, and have better thermal conductivity than PB-PP-R. First let us work with the stainless steel flange manufacturer to preheat and analyze the processing method of stainless steel flange. Stainless steel flange pipe fittings are made of steel plate. After the steel plate is cut into materials according to requirements, like UOE molding, it is also punched into a circle by punching. Have the two halves and then stitch and weld. After pushing, the flange should be shaped in this hot state. After shaping, the outer diameter and wall thickness of the flange pipe fittings have met the requirements. Next, the finishing process is performed. After shot peening, the scale on the inner and outer surfaces of the flange pipe is removed, and the two ends are beveled to facilitate welding. After the inspection, stamping, spray painting, packaging and other processes, it can leave the factory.

Stainless steel flange pipe fittings have two more procedures for flaw detection and heat treatment than other pipe fittings in the manufacturing process. Other procedures are the same. Because some flanges will be distorted if they are not handled properly, which is not allowed. In addition, after pushing the head, the outer diameter of the front end is generally large, and the shaping is performed by a shaping die. Due to the existence of welds, non-destructive testing is required. Due to the existence of welding stress, heat treatment is also required.

There are also many processing methods for stainless steel flange wholesale. Many also belong to the category of mechanical processing, and the most commonly used are stamping, forging, rolling, rolling, inflation, stretching, bending, and combined processing.

Stainless steel flange process explanation:

Roller method: Place the core check valve in the tube and push it with rollers for round edge processing

Rolling method: Generally, no mandrel is used, which is suitable for the inner round edge of thick-walled pipes.

Bulging method: one is to place rubber in the tube and compress with a punch above to make the tube protrude; the other method is to use hydraulic inflation to fill the middle of the tube with liquid and use the liquid pressure to bulge the tube into the required shape This method is mostly used in the production of bellows like ours.

Forging method: The end or part of the pipe is extruded with a swaging machine to reduce the outer diameter of the electric butterfly valve. Common swaging machines include rotary, link and roller.
