Hastelloy Socket Weld flanges were initially developed for use on small-size high pressure piping. Their static strength is equal to Slip On flanges, but their fatigue strength 50% greater than double-welded Slip On flanges. The connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, a space must be created between flange or fitting and pipe.

The purpose for the bottoming clearance in a Socket Weld is usually to reduce the residual stress at the root of the weld that could occur during solidification of the weld metal. The image shows you the X measure for the expansion gap.

The disadvantage of this flange is right the gap, that must be made. By corrosive products, and mainly in stainless steel pipe systems, the crack between pipe and flange can give corrosion problems. In some processes this flange is also not allowed. Also for this flange counts, that principle always firstly a pipe must be welded and then just a fitting.

Hastelly Socket weld pipe flanges are used in the applications where there are smaller sizes of high pressure pipes used. These pipe flanges ...
... are attached by inserting the pipe into the socket end and applying fillet weld around the top. This helps in better flowing of the fluid or gas inside the pipe. These socket weld pipe flange is available in all materials, sizes and specifications.
