70% vs 96% Silica Fabric: Which Grade Should You Choose? When specifying silica fabric for welding protection, furnace insulation, exhaust systems, fire barriers, or other high-temperature equipment, one of the first decisions is often the silica grade. Two common options are 70% silica fabric and 96% high silica fabric. Both are woven heat-resistant textiles, but they should not be considered int...

Fabric expansion joints for cement plants are flexible connections used in industrial gas ducts to accommodate specified thermal movement and equipment displacement. In kiln-related ductwork, preheater exhaust and clinker-cooler circuits, their construction must address the conditions at the individual connection—not simply the highest temperature associated with the production line. A heat-resist...

What Temperature Can Silica Fabric Withstand? BSTFLEX’s 70% woven silica fabric has a published working-temperature limit of 800°C (1472°F), while its 96% high silica fabric is specified for continuous thermal exposure up to approximately 1000°C (1832°F). These figures apply to the stated products—not to every material sold as silica cloth, and not automatically to their coated or adhesive-backed ...

A fire sleeve can fit the hose and still fail to pass over its end fitting. It can also pass over the fitting but sit too loosely along the hose. These are separate checks, and a useful fire sleeve size chart needs to address both. Select the sleeve inside diameter from the actual outside diameter of the hose, tube or finished cable bundle. Then check the largest fitting or connector the sleeve mu...

To measure custom sewn bellows, record the shortest and longest distances between the same two mounting reference points, the space required around the protected component, the maximum outside envelope and the dimensions of both end fittings. For a straight axial installation, the difference between the two installed lengths is the required bellows travel. A cylinder stroke or a photograph of an o...
