What is socket weld flanges?
Socket-weld pipe flanges are typically used on smaller sizes of high pressure pipes. These 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.
Do you weld slip on flanges?
How do slip-on flanges work? Slip-on flanges must be slid into the pipe before welding. In this case it is a double weld, both inside and outside, thus providing the durability they need to avoid leaks. Their pressure resistance is rated at approximately 2/3 of that of a welding neck flange.
What is flange types of flanges?
The key types of flanges are the welding neck, long welding neck, slip-on, socket weld, lap joint, threaded and blind flanges. In addition to these standard flanges, some special ones exist, called Weldoflange/Nipoflange and Elboflange, swivel flange, expander/reducer flange, and orifice flanges.
How do you weld a pipe flange?
For welding Neck and Lap Joint Stub and Flange applications an initial root gap spacing between pipe and flange should be 1/16” to 1/8”. The first bead must penetrate uniformly to the inside wall of the assembly thus assuring a strong joint. The final bead should be built up above the pipe O.D.
Can two fittings be welded together?
You can/may weld two fittings (elbow to elbow) or a fitting to a Weld Neck Flange WITHOUT a pup piece. You can/may “trim” an elbow (to a different angle) and weld it to another elbow or WN Flange WITHOUT a pup piece.
