Steel socket and butt-welding are two different methods of joining pipes. Pipe fittings socket welding involves heating the ends of pipes and inserting them into a socket joint, while butt-welding involves heating the ends of pipes and welding them together. Both methods are commonly used in plumbing and piping systems.
The pipes are simply heated and inserted into the socket, so it is ease of installations. While, The welding process creates a strong and seamless joint between pipes as suitable for high-pressure and high-temperature applications.
Socket joints provide a strong and leak-proof connection. While, butt-welding creates a smooth and consistent surface, reducing the potential for turbulence.
