INDUTEX woven fiberglass brake blocks are engineered specifically for drilling rigs and service workover units in the oil & gas industry. Formulated with specialized heavy weaves and high-performance resins, they feature uniform density and friction surfaces calibrated to match brake drum contours with extreme precision.
The blocks are manufactured from continuous fiberglass filaments blended with high-grade synthetic and natural fibers according to rigorous engineering criteria. The yarns incorporate brass or copper metallic wire inserts to deliver superior heat dissipation. The woven material is thoroughly impregnated with proprietary thermosetting resins and precision-cured to maintain a continuous, stable friction coefficient across both low and elevated operating temperatures.
Complete block sets include non-asbestos wiper blocks, brass attachment bolts, and heat-resistant sealing plugs.
| Feature | Technical Specification & Details |
|---|---|

| Engineered Kits | Includes precision-machined blocks, calibrated fastening bolts, and thermal sealing plugs. |
| Wiper Blocks | Non-asbestos drum conditioners designed to eliminate drum scoring and uneven friction wear. |
| Global Delivery | Custom production ready for export shipment within a maximum lead time of 45 days. |
Manufactured strictly to OEM engineering drawings and drawworks specifications from leading global manufacturers.
Our flat-head bronze screws have a 120° chamfered face that keeps them firmly fitted to the block's hole seats.
Also included are recommended safety nuts for securely mounting the brake shoes.
The plugs are tapered to provide tight, reliable retention in block recesses, manufactured from a specialized synthetic rubber polymer that resists extreme operational temperatures without degrading.
Specially molded conditioning blocks positioned along key sections of the brake band. They deliver non-abrasive cleaning and polishing action across the brake drum flange, preventing metal pickup on adjacent blocks and promoting a uniform wear pattern.
INDUTEX offers custom-engineered block sets tailored for all recognized drawworks makes and models.
