Core Services / On-Site Machining
Precision machining solutions delivered directly to your facility.
RWNA owns and operates state-of-the-art hydraulic & pneumatic torque wrenches supported by qualified and experienced manpower. A hydraulic torque wrench is a tool designed to exert torque on a connection through the use of a hydraulic system, applying a pre-determined, controlled amount of torque to a properly lubricated fastener for accurate tightening or loosening. With our highly trained personnel, we are also able to cater for highly customised solutions.
RWNA has highly trained technicians and state-of-the-art hydraulic equipment for all bolting needs. We offer an accurate method of tightening threaded fasteners through hydraulic tensioning technology, ensuring accurate bolt loading in a controlled and safe manner that consistently meets the stringent needs of the oil and gas industry.
RWNA’s on-site flange facing and milling teams are committed to producing a high quality surface finish on all types of flange face, seal groove, weld preparation and counter boring.
RWNA’s on-site milling service provides a precise, cold-work solution for restoring large-scale flange faces and sealing surfaces to exact OEM specifications — without removing equipment from service. Our specialist fleet is engineered for the most demanding conditions in the oil and gas sector, delivering repeatable, workshop-grade results directly at your facility.
RWNA caters to your onshore or offshore on-site machining needs for cold cutting and pipe end preparation. This method is conducted in hazardous environments where traditional torch or grinder methods are unsuitable, producing a high quality end result with a higher level of safety assured.
RWNA’s on-site line boring service restores bores and housings to exact concentricity, eliminating the need to transport heavy machinery to a workshop. Ideal for pivot points, bearing housings, and large-scale piping, our field-deployable equipment delivers workshop-grade precision directly at your facility — minimizing downtime and extending the operational life of critical assets.
With RWNA’s onshore and offshore on-site Pipe End Preparation service, you can eliminate the reliance on oxy/acetylene for end prep. RWNA owns and operates advanced machines engineered for precision bevelling, facing, counterboring, squaring, and other end prep requirements on light wall, heavy wall pipe, tube, or casing — designed for the rigorous demands of onshore and offshore environments.
RWNA presents the best cold tapping solution that allows a branch connection to be made into piping or vessels while the system remains live and under working pressure, with no requirement for shutdowns — reducing downtime and costs to our clients.
With RWNA’s onshore and offshore on-site Tube Facer service, you can eliminate reliance on manual filing, grinding, or imprecise cutting for tube end preparation. RWNA owns and operates advanced Tube Facer machines engineered for precision facing, squaring, and light beveling on thin-walled tubes, stainless steel, titanium, and other alloys — designed for the rigorous service requirements of onshore and offshore environments.
RWNA provides comprehensive valve testing and servicing solutions for all valve types — from on-site repair, lubrication and sealant injection to full workshop overhaul. Our fully equipped workshop and experienced team ensure valves are restored to peak performance, consistently meeting the stringent safety and quality requirements of the oil and gas industry.
