GPT flange insulation products are made of high quality engineering materials. Insulation products include a range of insulation / sealing gaskets and various sleeves and washers. For best flexibility, parts can be ordered separately or with a complete flange insulation kit.
Flange insulation kits are specifically designed to work with our insulation gaskets to affect the overall electrical insulation of the flange assembly. The insulation kit includes a full-length insulating sleeve, two insulating washers, and two steel washers, which are used by each bolt in the flange assembly. The insulating sleeve is used to realize the electrical insulation of the bolts and the flange sections, and the insulating washer is used to achieve the electrical insulation of the connection nuts of the bolts. This insulation method is a highly reliable solution for users to complete the electrical insulation of flange joints.
