Double Wall Piping System
Double wall pipes are primarily designed to safely transport or store hazardous liquids and gases. Double wall pipes consist of an inner pipe and an outer pipe. This dual structure plays a critical role in reducing the risk of leaks and preventing environmental contamination.
LNG Fuel Gas Supply Piping System
Double Wall Piping System is to supply the fuel gas to main engine with purpose of protection of explosion and leak-check mainly.
Double wall pipe has excellent performance against high pressure and extreme temperatures.

Vacuum Insulated Piping System
Vacuum Insulated Pipes are double-walled vacuum insulated piping systems specifically designed to safely and efficiently transport cryogenic fluids, such as LNG, liquid oxygen, and liquid nitrogen. These pipes maximize insulation performance to minimize exposure of the fluid to external heat, protecting it from vaporization due to heat transfer.
