The roller reamer body is connected to the drill pipe using a threaded connection, which ensures a secure and stable attachment. The use of drilling fluid helps to cool and lubricate the roller cutters, preventing them from overheating and wearing down prematurely. The roller knives are mounted on bearings that allow them to spin freely as they come into contact with the hole wall, ensuring efficient cutting action.
The body of the Roller Reamer is made of high-quality alloy steel, which provides excellent strength and durability. After undergoing heat treatment, the Brinell Hardness of the material ranges from 285 to 341, while its impact energy is 54J. This ensures that the reamer can withstand the harsh conditions of drilling without compromising its performance.
The threads on the Roller Reamer are cold rolled and treated with phosphate, providing a corrosion-resistant finish. Additionally, they are protected with thread protectors that comply with API Specification, further enhancing their durability and reliability.
Ultrasonic inspection is carried out on each part of the Roller Reamer's body, ensuring that it meets the required standards for quality and performance. The parts are heat treated and machined with precise dimensional control, resulting in accurate and consistent dimensions.
Before and after manufacturing, the roller reamer parts are inspected to ensure conformance to interchangeability needs and requirements. This ensures that replacement parts can be easily swapped out if necessary, reducing downtime and maintenance costs.
An improved combination of rollers and pressure blocks allows for easy replacement of cutters, while also providing enhanced lubrication for smooth operation. This design feature ensures that the Roller Reamer can maintain optimal performance throughout its lifespan, making it an essential tool for drilling operations.
