Description

technical field

[0001] The invention relates to a welding device for a bent pipe and a flange, in particular to a bent pipe correction tooling platform and a pipe correction method. Background technique

[0002] In the shipping industry, there are pipes everywhere in the ship, and a series of operations such as the design and manufacture of these pipe fittings and the inspection after installation in the ship are called "pipe laying". Usually ships are constructed and installed in sections. When the sections are closed, the pipelines between the sections need to be connected by closing pipes. However, it is impossible to manufacture all kinds of closing pipes only by relying on the pipeline design drawings. The production of closing pipes is usually Adopt type method and field welding method.

[0003] The type-taking method is to fix the two flanges to the flanges of the two pipes that need to be connected, then weld the two flanges into a whole with angle iron, transport t...
