Here are some helpful resources to serve your job role.
GPT flange isolation(insulation) products are constructed of premium engineering materials. The isolation products include a wide selection of isolating/sealing gaskets along with a variety of sleeves and washers. For maximum flexibility, components may be ordered separately or as part of complete flange isolation kits (FIK).
GPT engineers and manufactures a range of high quality sealing and isolating products used to ensure the safe flow of fluids in transmission, distribution and process piping systems. Flange isolation products include a wide selection of isolation joints and spools that are available in all pipe sizes, types, pressure ratings, and materials.

The GPT Torque Calculator allows you to generate specific torque values and basic gasket dimensions for your exact application. Use the product selection tab to fill in which product you are using, and flange details to highlight the flange specifics. Torque will then be based on the bolt grade, coefficient of friction, and bolt stress. Please note that GPT utilizes an assumed coefficient of friction of 0.11 for uncoated bolts utilizing Pikolube, and a bolt yield of 30% for standard gaskets, and 50% bolt yield for fire safe gaskets
