It is used for the transportation of gas fuel or high-risk media on ships and platforms. The inner pipe transports fuel liquid or other fluids, and the outer pipe carries out safety monitoring and protection.
The inner pipe is a fuel pipe. When an abnormal leak occurs, the outer pipe can protect the surrounding environment, give an alarm and exhaust the gas through the exhaust system.
The analysis of the double-wall pipe takes into account the effects of wave load, ship motion acceleration, vibration of connected equipment, and system weight and thermal stress.
The scope of technical services includes design, calculation and analysis of double-walled pipelines, and submission of drawings, materials, and technical support in the process.
The scope of production services includes prefabrication, in-field tests and inspections, pickling passivation, installation of out-field tests and inspections, and is approved by the classification society.
