product description :

Welding neck flange

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 flange

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 flange

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 flange

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 flange

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

Why use the lap joint flange?

Lap joint flange can swivel around the stub end and pipe lining. When the piping system is assemble and disassemble frequently, it is better to use a Lap joint flange. It means the flange can work even the two flanges bolt holes are misalignment .

In a corrosive situation, the flange joints need to be exchange very soon. To a lap joint flange, only the stub end is touch with the pipe and fluid , the backing flange no need to touch it . It means you could only replace the stub end , no need to replace the backing flange , so the lap joint flange can decrease the cost of the piping systems.

The backing flange and the stub end is separated , so we can use two different materials for the two pieces. it can work for more complicated application.
