Product Description

WELONG's Roller Reamer: Precision and Reliability for the Oil & Gas Industry

With over 20 years of manufacturing experience, WELONG proudly presents its renowned roller reamer, a cutting-edge tool designed specifically for boring operations in the oil and gas industry. Our roller reamers are meticulously crafted to meet our customers' specifications, ensuring optimal performance and maximum efficiency.

The primary function of WELONG's roller reamer is to enlarge the borehole during well drilling operations. This is achieved by cutting through various earth formations to achieve the desired size, which may be necessary when the drill bit becomes under-gauged due to wear.

We understand that different drilling conditions demand different tools. That's why WELONG offers a range of roller cutter types to cater to various formation types: Hard Formation, Medium to Hard Formation, and Soft Formation. Our roller reamers are available in hole sizes ranging from 6" to 42", providing versatility to suit different project requirements.

At WELONG, we prioritize quality and reliability. All the materials used in the production of our roller reamers come from reputable steel mills. The steel ingots undergo electric furnace smelting and vacuum degassing processes to ensure superior quality. Forging is carried out using hydraulic or water presses, with a minimum forging ratio of 3:1. The resulting product exhibits excellent grain size of 5 or better, and cleanliness, meeting ASTM E45 standards for average inclusion content.

To guarantee structural integrity, our roller reamers undergo thorough ultrasonic testing following the flat-bottom hole procedure specified in ASTM A587. Both direct and oblique inspections are performed to identify any potential flaws. Furthermore, our roller reamers adhere strictly to the API 7-1 standard, ensuring compliance with industry regulations.

Before shipment, WELONG's roller reamers undergo meticulous surface cleaning. After surface preparation with a cleaning agent, they are left to dry completely before being coated with rust preventive oil. Each roller reamer is carefully wrapped in white plastic sheeting, followed by tightly secured green fabric wrapping to prevent any leakage or damage during transportation. To ensure maximum protection during long-distance shipping, our roller reamers are packaged using sturdy iron frames.

WELONG takes pride in not only delivering high-quality products but also providing excellent customer service. Our team is committed to meeting and exceeding customer expectations, offering comprehensive after-sales support to ensure complete satisfaction.

Choose WELONG's roller reamer for your drilling operations and experience the perfect blend of precision, durability, and exemplary service.
