[0002] Pipe fittings are collectively referred to as components in a pipeline system that play roles such as connection, control, direction change, flow diversion, sealing, and support. In order to extend the length of pipe fittings, they are usually clamped on a clamp for butt welding.
[0003] Currently, the diameter of the inner ring on existing clamps is usually a fixed size. When clamping pipe fittings with a small size, the contact surface with the arc-shaped clamp is small, which easily leads to slipping problems during the processing.
[0004] The reason for this problem is that currently, pipe fittings are mainly clamped and fixed on the arc-shaped clamp separately for moving butt joint. Since the diameter of the inner ring on the arc-shaped clamp is usually a fixed size, and when clamping pipe fittings with a small size, the contact surface with the arc-shaped clamp is small, resulting in poor tightness between the two, which easily causes slipping during the processing, making the applicability of the arc-shaped clamp relatively low. In view of the deficiencies of the prior art, we propose a pipe fitting welding butt joint positioning clamp to solve the above problems. Content of the Utility Model
