304 stainless steel flat welding flange has the following advantages:

1. 304 stainless steel flat welding flange welding device is easy to align, and the device is simple and convenient;

2. It is widely used in many industries, such as metallurgy, machinery, chemical industry, petroleum, machine tool, water conservancy, construction, engineering, shipbuilding, environmental protection, coal, agricultural machinery, food, boiler and pressure vessel, etc;

3. Beautiful appearance, smooth and lubricated appearance of flat welding flange, mainly used for carbon steel pipe connection;

4. Easy to disassemble and check the pipeline condition;

5. Connect the pipeline, and the flat welding flange can also maintain the sealing performance of the pipeline.

Defects of 304 stainless steel flat welding flange include:

1. Poor rigidity, do not use in hazardous situations;

2. The shape features are easier to bump during transportation.

Welding neck

1, Preferred for high-pressure, subzero or elevated temperature

2, Hub is tapered and bored to match pipe's inside diameter so flow is not restricted, preventing turbulence and reducing erosion

3, Easily radiographed and provides excellent stress distribution

Slip-on

1, Not normally used in high-stress applications due to low hub and weld attachment

2, Silps over outside of pipe

3, Inside of flange welded at hub and end of pipe

Lap joint

1, Used where bolt alignment or access for cleaning is required

2, Similar to slip-on flange when used with lap joint stub end

3, Radius at intersection of flange face and bore to match lap joint stub end

Threaded

1, Used where welding would would be hazardous

2, Designed for low-pressure and non-cyclic applications

3, Bore is threaded to match pipe thread

4, Tapered to seal pipe and flanges

Socket welding

1, For small-diameter chemical processes, hydraulic and stream distribution lines

2, Similar to slip-on flange

3, Counter bore matches pipe bore, allowing unrestricted flow

4, Counter bore from hub side fits pipe's outer diameter – can insert pipe in socket with fillet weld at hub
