The main treatment of the 304 316 Stainless Steel So Flange scale is by sandblasting or chemical treatment. After the treatment, it looks basically nothing out of the ordinary. The following two treatment methods for the stainless steel flange scale are introduced:
1. Sand blasting (pellet) method: mainly use the method of spraying micro glass beads to remove the black oxide scale on the surface.
2. Chemical method: Use a non-polluting pickling passivation paste and a non-toxic cleaning solution with inorganic additives at room temperature for dipping. So as to achieve the purpose of whitening the natural color of the stainless steel flange.
After processing, it basically looks like a dull color. This method is more suitable for large, complex Stainless Steel So Flange products.
There are various processing methods of 304 316 Stainless Steel So Flange. The processing procedures that are often used are: stamping method, forging method, rolling method, rolling method, expansion method, stretching method, bending method, compound processing Law.
Here are some common processes:
Rolling method: Use a roller to press the outer circumference of the core check valve in the tube. For rim machining.
Rolling method: Mandrel is generally not used. Fits inside rims with thick wall tubes.
Expansion method: Put rubber in the hose, compress the top with a punch, and then protrude the hose into shape. Another method is hydroexpansion forming, in which the central part of the hose is filled with liquid, and the pressure of the liquid is used to expand the hose into the necessary shape. This method is commonly used in the production of stainless steel flanges.
Forging method: use a die forging machine to extrude the end or part of the pipe into an electric butterfly valve to reduce the outer diameter. Commonly used die forging machines include rotary, connecting rod and roller types.
