Abstract

The invention discloses a multifunctional low-temperature pipe clamp and application thereof to correction and assembly of a LNG ship low-temperature pipe. The low-temperature pipe clamp comprises a pipe clamp main body; the pipe clamp main body includes two half clamp bodies, an adjusting bracket and an adjusting mechanism; the half clamp bodies are provided with multiple fixed holes; and the adjusting bracket penetrates through the fixed holes to fixedly connect with the adjusting mechanism. The low-temperature pipe clamp can synchronously finish ovality correction and spot welding assembly of the low-temperature pipe, is wider in application range and high in generality, saves the construction time, and improves the production efficiency; and the low-temperature pipe clamp is used for assembling the LNG ship low-temperature pipe, so that the assembly process of the low-temperature pipe can be simplified, and the assembly time of the low-temperature pipe is shortened.

Description

technical field

[0001] The invention relates to the technical field of shipbuilding tooling, in particular to a multifunctional low-temperature pipe clamp and its application in the correction and assembly of low-temperature pipes of LNG ships. Background technique

[0002] Pipe clamps are suitable for fixing pipes with oil, water and gas as the medium. They are generally used in heavy machinery, construction machinery, ships, light textile and agricultural machinery and other industries.

[0003] Due to the particularity of its cargo, LNG ships need to load liquefied natural gas, and their decks, cargo machinery rooms and other areas need to be equipped with a large number of austenitic stainless steel pipes (hereinafter referred to as: cryogenic pipes) used in low temperature conditions of LNG ships. Usually, the low-temperature tubes are connected by welding, which requires high precision and strict welding requirements. After the cryogenic pipe is butt-jointed and assem...
