GPT Products

Isolation Gaskets / Kits

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).

Monolithic Isolation Joints

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.

Knowledge Hub

GPT is committed to providing pipeline solutions with unmatched safety, performance and reliability in some of the world’s most demanding environments. Our teams of industry-focused engineers use advanced materials and manufacturing processes to develop innovative sealing and isolating systems uniquely tailored to the specific industry and application.

Why Use Isolation Kits and Joints?

Corrosion is constantly attempting to degrade the performance of metal pipelines. The corrosion can be from dissimilar metals (galvanic corrosion), stray current corrosion from unintended sources of electricity, simple corrosion […]

Emissions

Emissions, or specifically fugitive emissions are the result of poorly sealed oil and gas pipelines and infrastructure. With increased scrutiny from governments, regulators and environmental groups there has never been a more important time to tackle this pressing challenge.

Pipeline Corrosion Prevention

Corrosion is the primary factor affecting the longevity and reliability of pipelines that transport crucial energy sources throughout the globe. The average annual corrosion-related cost is estimated at $7 billion to monitor, replace, and maintain these assets. The corrosion-related cost of operation and maintenance makes up 80% of this cost. Learn how to prevent, mitigate and reduce corrosion cost.

EPC Page

GPT stands behind its sealing and corrosion prevention solutions with an expert team of applications engineers and laboratory professionals to provide comprehensive global support for your sealing and cathodic protection needs.

From field training to on-site inspection and laboratory conformity analysis, we have the resources and personnel to ensure you stay safe, on schedule and within budget.

Torque Calculator

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
