Weldolet is used for Butt weld branch connection where standard tee is not
available due to size restrictions and the piping is of critical / high pressure service.
There are many types of weldolet fittings. There are different sizes to fit different items.
Weldolet has a Bevelled end to butt weld the pipe whereas in sockolet the pipe/tube goes inside it and there it is fillet welded.
A weldolet is a fitting you weld on a (run) pipe, and then butt weld a branch pipe to it. A tredolet is a fitting you weld on a (run) pipe, and then screw a threaded branch pipe to it. Some people call this a threadolet A sockolet is a fitting you weld on a (run) pipe, and then socket weld a branch pipe to it. A nipolet is the same as a weldolet or thredolet but has an elongated branch connection. You have to specify if it's a welded or threaded nipolet.
yes
No, fittings go over the pipe
You cannot do that effectively without taking the fittings apart,
Not sure what you mean by pressure fittings. Threaded fittings for steel pipe are pressure fittings. Steel pipe with a 3/4" O.D. is known as 1/2" I.P.S. (Iron Pipe Size) pipe.
Weldolet and Sockolet are basically self reinforced fittings. Weldolet is used for Butt weld branch connection where standard tee is not available due to size restrictions and the piping is of critical / high pressure service. Sockolet is used for socket welding branch connection, which require reinforcing pad.
Weldolet is a trademarked name by Bonney Forge for internally reinforced forged branch outlet fittings. Pipet is a trademarked name by WFI for internally reinforced forged branch outlet fittings. Both comply with MSS SP-97 Internally Reinforced Forged Branch Outlet Fittings - Socket Welding, Threaded and Buttwelding Ends. Referenced in ASME B31.3-2020 304.3.1 a) (1). They are the same
There are a few places in Houston where one can purchase pipe fittings. A good place to try is Pipe Fittings. Another good place to try is Home Depot.
No, they need to match.
