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.
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.
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.
A wedolet is a butt-weld branch connection. It is used to minimize the stress concentration and to provide integral reinforcement.
A Weldolet is a butt-weld branch connection. It is designed to provide integral reinforcement and minimize stress. They are made to match or exceed the schedule of the pipe.
First, Butt-weld is short for a butt groove. Welding in a butt-groove starts at the throat of the butt-groove. The first weld point could be a tack-weld: holding the two materials to be welded together. The throat is measured and filler metal and electrode are determined to create the root pass.
A butt weld is a weld made between two straight cut profiles , a socket , or plug weld is made between a surface and a hole.
Socket weld, because it's stronger; butt weld, because it uses less metal. The "best" weld depends on what you're building.
there are 3 types of welded joint 1-butt weld butt weld is the type which need usually 4 mm clearance between the 2 edge of pipe or plate you want to weld it. 2-socket weld 3-seal weld
A butt weld is where the diameter of the pipes welded together are the same, a socket weld is where a larger diameter pipe is fitted into a smaller one. In making a butt weld, the pipes (or pipe and fitting) usually have an angle machined or ground into the outside corner, so when they are placed together face-face, there is a circumferential V shaped gap serving as the weld prep. In a socket weld, the pipe is inserted into the socket, backed off slightly to make a gap between the end of the pipe and the bottom of the socket, and the weld is made around the outside diameter of the socket to the outside diameter of the pipe. The gap at the bottom of the pipe prevents thermal expansion from stressing the joint during or after welding.
To unite by a butt weld.
The step-by-step instructions on how to do a weld fitting on a A234 with a pipe of API 5L x60 w TH11.9 mm is not listed. It might be best to purchase a weld fitting manual for a A234 for further information.
