![]() ![]() ![]() What’s more, it has an expansion coefficient 10 times inferior than traditional stainless steel. There are many factors that affect the pipe-wall-thickness requirement, which include: The maximum and working pressures Maximum and working temperatures Chemical properties of the fluid The fluid velocity The pipe material and grade The safety factor or code design application If there are no codes or standards that specifically apply to the oil and gas production facilities, the design engineer may select one of the industry codes or standards as the basis of design. We also have a qualified supply chain with unique experience.ģ6Ni alloy has been used for decades in the LNG carriers, and is the perfect cryogenic material: it gets stronger as it cools and retains its ductility. ITP has developed the pipe production using 36Ni, and the associated welding and inspection required for pipeline construction. The non-ageing nature of Izoflex also means zero maintenance. This results in reduced requirement for weight coating and narrower pipeline corridors. ![]() Only 2 inches of Izoflex insulation is typically required for LNG applications, which enables us to provide the most compact cryogenic pipeline. The cold insulation used in our cryogenic piping systems is Izoflex LT®, which has the lowest conductivity on the market and requires no maintenance. Our insulated cryogenic pipeline systems have been qualified by DNV-GL and several operators. This cryogenic piping design provides both additional protection from external damage and containment from potential leaks. The double envelope corresponds to the double-hulled carriers and full containment tanks, which are standard in the LNG industry. Our cryogenic technology allows for continuous pipeline integrity monitoring based on the closed annulus volume pressure monitoring, resulting in leak detection orders of magnitude more sensitive than traditional mass balance systems. ![]()
