1. Structure and Composition
Brake pads for oil drilling rigs are significantly larger than automotive brake pads and require extreme heat resistance:
-
Backing Plate: LONGWELL utilizes high-quality carbon steel or alloy steel to ensure zero deformation under high-pressure conditions.
-
Friction Material Layer:
-
Non-Asbestos Material: In compliance with modern industrial standards, LONGWELL pads are 100% non-asbestos, formulated from a high-performance composite of resin, semi-metallic fibers, ceramic fibers, and lubricating fillers.
-
High Friction Coefficient: Maintains a stable friction coefficient—typically between 0.40 and 0.50—even under high-temperature operation.
-
-
Accessories: Includes integrated wear indicators (sensors), anti-noise shims, and other essential hardware.

2. Core Technology: Heat Dissipation and Wear Resistance
Given that oil drilling depths can reach several thousand meters, the heat generated during braking is immense:
-
Thermal Fade Control: LONGWELL brake pads are engineered to withstand instantaneous high temperatures ranging from 300℃ to 500℃ without compromising braking performance.
-
Cooling Compatibility: To manage these extreme loads, the drawworks brake discs are typically equipped with circulating water-cooling or forced air-cooling systems.
