Problems solved by technology

In the straight seam welded pipe, when welding, it is necessary to make the opposite side walls of the welding gap abut against each other properly before welding. However, when the two side walls abut against each other, the edges of the side walls are easy to face when the pressure is too large. The outer side of the welded pipe is warped, which affects the subsequent welding quality

Embodiment Construction

[0019] The invention relates to a steel pipe and its welding system. For example, steel pipes are welded pipes welded by this welding system. The steel pipe is a thin-walled steel pipe. For example, a steel pipe welding system includes a jacking assembly and a welding mechanism. The jacking assembly includes a jacking frame, an L-shaped frame, a jacking cylinder, a jacking plate, and a plurality of arc-shaped jacking bars. For example, the lifting frame includes a mounting plate, a first side wall plate and a second side wall plate. For example, the middle part of the mounting plate is provided with a transverse groove, the first side wall plate and the second side wall plate are respectively vertically fixed on opposite sides of the mounting plate, and the top of the L-shaped frame is fixed on the first side wall plate. For example, the bottom of the L-shaped frame is fixed on the ground, and the jacking cylinder is installed on the bottom of the L-shaped frame. It is fixe...

Abstract

The invention relates to a steel pipe and a welding system thereof. The welding system of the steel pipe comprises a jacking assembly and a welding mechanism, the jacking assembly comprises an L-shaped frame, a jacking frame, a jacking air cylinder, a jacking plate and a plurality of arc-shaped jacking strips, the jacking frame comprises a mounting plate, a first side wall plate and a second sidewall plate, and the first side wall plate and the second side wall plate are perpendicularly fixed to the two opposite sides of the mounting plate correspondingly; the L-shaped frame is fixed to the first side wall plate, the bottom of the L-shaped frame is fixed to the ground, and a transverse groove is formed in the middle of the mounting plate in a penetrating mode. The jacking air cylinder ismounted at the bottom of the L-shaped frame, and the jacking plate is connected to an output shaft of the jacking air cylinder and arranged in the transverse groove in a penetrating mode. The steel pipe welded by the welding system of the steel pipe is better in quality.

Description

technical field [0001] The invention relates to a steel pipe and its welding system. Background technique [0002] Since the 1990s, with the rapid development of continuous rolling production of high-quality strip steel and the advancement of welding and inspection technology, the quality of welding gaps has been continuously improved, and the varieties and specifications of welded steel pipes have increased day by day, replacing seamless steel pipes in more and more fields. Seam steel pipe. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the form of welding gaps. In the straight seam welded pipe, when welding, it is necessary to make the opposite side walls of the welding gap abut against each other properly before welding. However, when the two side walls abut against each other, the edges of the side walls are easy to face when the pressure is too large. The outer side of the welded pipe is warped, which affects the su...
