Product Q&A

Q:What is the difference between reverse circulation (RC) drill rig and forward circulation drill rig?

The core difference lies in the slag discharge mode. RC drill rig adopts 'outside-in' circulation: flushing fluid flows from the annulus to the hole bottom, and carries cuttings back through the drill pipe inner cavity. It has faster slag discharge (30%-50% higher efficiency), less bottom sediment, and is more suitable for large-diameter and deep-hole operations in complex formations (pebble, hard rock). Forward circulation is only suitable for shallow, small-diameter drilling in soft formations

Q:What formations can the RC drill rig work on?

It has strong adaptability, applicable to clay, sand, pebble layer, cemented gravel, medium weathered rock and hard rock. It can also work in arid, water-scarce and remote areas, meeting harsh working environment requirements.

Q:What is the maximum drilling depth and diameter of your RC drill rig?

Our standard models support drilling diameter of 105-3000mm and drilling depth of 50-1200m. We also provide customized services according to your specific project needs (e.g., deeper depth or larger diameter).

Q:What after-sales services are provided?

We provide 24/7 online service with professional technical support, long-term quality warranty for core components, free technical guidance for installation and operation, spare parts supply with favorable price and fast delivery, overseas engineering support for on-site debugging and training, and lifelong after-sales service for maintenance and repair.

Q:Is the drilling rig suitable for off-grid sites?

Yes, it is equipped with a reliable diesel power unit, making it suitable for outdoor off-grid construction sites.
