Slip on weld fange can be slid onto a pipe and then welded in place. It is made of carbon steel, alloy steel, and stainless steel. Slip on flange is a type of flange that extends steel pipes, pipe fittings, etc, into the flange and connects with equipment or pipelines through fillet welds. This flanges have short neck, which increases the strength of the flange and improves the bearing capacity of the flange. So it can be used on higher pressure pipelines.
Socket welding flanges were initially developed for use on small size high pressure piping. When provided with an internal weld, their static strength is equal to, but their fatigue strength 50% greater than double welding slip on flanges.
These socket-weld pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe.
Socket-weld flanges were initially developed for use on small-size high pressure piping. Socket-Weld Flanges has a female socket in which pipe is fitted. Fillet welding is done from outside on the pipe.
Lap joint flanges are primarily employed with lap joint stubs, the combined initial cost of the two items being approximately one third higher than that of comparable Welding Neck Flanges. Their pressure holding ability is little, if any, better than that of slip on flanges and the fatigue life of the assembly is only one tenth that of welding neck flanges.
ASME Flange include B16.5 Flange, B16.47-A Flange, B16.47-B Flange, this standard system include slip on flange, blind flange, welded neck flange, Threaded Flange, lapped joint flange (loose flange), socket welded flange, B16.36 Orifice Flange, long Weld Neck Flange and Special Flange, sizes from 1/2 inch to 60 inch, class 150, class 300, class 600, class 900, class 1500, class 2500.
