Description

Technical Field

[0001] The invention relates to the technical field of bending for ship pipeline processing, and in particular to a bending device for ship pipeline processing. Background Art

[0002] Ship pipelines are used to connect various mechanical equipment on ships and are used to transmit water, oil, gas and other related working fluids. There are two major categories of ship pipelines, power pipelines and ship system pipelines. Power pipelines are various pipelines used to serve the main engine and auxiliary engine, including fuel oil, lubricating oil, cooling water, compressed air, exhaust, waste heat and other pipelines. Ship system pipelines are designed to improve the ship's anti-sinking and stability. In order to meet the normal living needs of crew members and passengers, there are many ship systems, including water supply systems for supplying seawater and fresh water to the entire ship, ballast water systems for regulating ship ballast, bilge water discharge systems for removing bilge water, compressed air systems for providing compressed air to the entire ship, fire fighting systems for fire extinguishing, etc. These pipelines need to be bent according to the route used to complete the transportation task.
