Flat-Welded Stainless Steel Flanges

304 stainless metal flange



A extra versatile stainless steel

304 is a tremendously versatile stainless steel, which is broadly used in the manufacture of gear and components that require suitable complete homes (corrosion resistance and formability).

304 stainless metal is a grade of stainless metal produced in accordance with ASTM standards. 304 is equal to 0Cr19Ni9 (0Cr18Ni9) stainless metal in China. 304 consists of 19% chromium and 9% nickel. 304 is a extensively used stainless metal and heat-resistant steel. It is used in meals manufacturing equipment, Xitong chemical equipment, nuclear energy, etc.

304 stainless metal flanges are the identical as different fabric flanges, and there are thirteen frequent types:

1. Flat welding flange (flat panel flange) The pipe need to be inserted into the flange welded in the internal ring of the flange.

2. Butt welding flange (English name: welding neck flange) with neck, clean transition section, and pipe for butt welding flange.

3. Socket welding flange (English name: socket welding flange) is a flange with socket welding and socket welding connection with the pipe.

4. Threaded flange (English name: threaded flange or screwed flange) is a flange with threads and a threaded connection with the pipe.

5. Loose flange (English name: lapped joint flange or free flange) is a flange used in mixture with a flanging brief joint or welding ring on the pipe.

6. Special flange Non-round flanges, such as diamond flanges, rectangular flanges, etc.

7. The lowering flange (also recognized as the measurement flange) (English name: decreasing flange) is linked with the general flange, however the nominal diameter of the pipe is smaller than the flange of the nominal diameter of the preferred flange.

8. The sealing floor of the full aircraft flange (English name: flat face flange) is the flange of the identical airplane as the complete flange face.

9. The sealing floor of the raised face flange (English name: raised face flange) is barely higher than the flange of the whole flange face.

10. Concave and convex face flanges (English name: male and girl face flanges) are a pair of flanges, and their sealing surfaces are concave and convex.

11. tongue and groove face flanges (English name: tongue and groove face flanges) have a pair of flanges with their sealing surfaces, one has a tenon, and the different has a groove that fits the tenon.

12. The sealing floor of the ring joint face flange (also recognized as ring joint face flanges) flange is a trapezoidal ring groove.

13. The stainless metal flange cowl (also acknowledged as the blind flange) (English name: clean flange or blind flange) is related with the pipe cease flange to shut the pipe and a spherical plate with bolt holes. In order to stop rust and cracks on the floor of the stainless metal flange, the floor of the carbon metal flange is typically covered with electroplating layer (yellow zinc, white zinc, etc.), or brushed with anti-rust oil and sprayed with anti-rust paint.
