Blast Cleaning
Ramco has been providing the industry with the care and maintenance of OCTG and drilling tubulars since 1977.
Ramco has led the way in the development of blasting OCTG and delivering the highest standards of surface preparation. Its blasting services include automated grit blasting and preparation of internal and external surfaces and abrasive cleaning to remove millscale and corrosion prior to final use or application of coatings.
Consistently delivering better results than its competitors, Ramco has been at the forefront of the development of advanced grit blasting technologies.
Service Offering
Ramco is probably best known for its OCTG abrasive blast cleaning services, a service they have been providing and developing for over 40 years. Utilising its in-house blasting technology, Ramco can provide OCTG blast cleaning services for both OD and ID requirements, achieving SA2 and SA2.1/2 specifications.
Ramco’s blasting technology has been utilised in many locations, primarily within its own in-house purpose built facilities, however Ramco has mobilised the technology through its Pipe Care Units (PCU’s) service and provided blast cleaning services onsite at locations around the world.
Ramco is currently the only company with the ability to blast to SA2 and SA2.1/2 on Corrosion Resistant Alloys (CRA) and has recently taken its technology into new areas and provided blast cleaning services on line pipe and other tubular products.
Blasting services include:
- Internal surface cleaning – utilising high-performance air compressors and grit medium to remove mill scale and rust from inside the pipe, Ramco ensures the best in class industry standard for surface finish
- External surface cleaning – utilising high-performance air compressors and grit medium to remove mill scale and rust from outside the pipe, Ramco ensures the best in class industry standard for surface finish
Benefits
Blasting tubulars achieves a surface finish free of mill scale suitable for final use downhole or for further coating requirements.
The removal of mill scale and loose ‘rust’ ensures that no foreign bodies are present when the pipe is run downhole. This scale, if not removed, can fall off and contribute to build up downhole often affecting equipment both on surface and downhole.
Removing external scale and corrosion ensures a clean surface, if not removed this scale and rust can clog and damage running tools and equipment or end up in the well bore.
