The pressure rating of Buttweld fittings depends on the material, size, and temperature of the pipe. Buttweld fittings can have pressure ratings ranging from 2000 PSI to 6000 PSI.

The four main types of welds are butt weld, fillet weld, plug weld, and groove weld.

Buttweld fittings are used for larger pipe sizes where high pressure and temperature are involved, while socket weld fittings are used for smaller pipe sizes and low-pressure applications. Buttweld fittings are joined by welding, while socket weld fittings are joined by inserting the pipe into the socket and then welding the joint.

Buttweld fittings are used in various industries such as oil and gas, petrochemical, chemical, pharmaceutical, and food processing. They are used in piping systems to connect pipes and change the direction of flow.

Buttweld fitting is a type of pipe fitting used to connect two pipes of similar or different diameters. It is characterized by a welded joint at the end of the fitting, which is then connected to the pipes by welding.
