The inner circular surface of the oil drilling tool sleeve is eroded by mud and will quickly wear out and fail. Conventional repair and strengthening methods make it difficult to truly extend the service life of parts. The use of deep-hole laser cladding to repair and strengthen the eroded parts of the inner wall can not only restore the original dimensions of the parts but also greatly improve the service life of the parts.

The design concept of Huirui’s inner hole laser cladding head is mainly to meet the needs of repairing the inner walls of industrial parts and narrow spaces. It can perform laser cladding on the inner walls of parts. The laser head can penetrate into a depth of up to 3 meters. It has been widely used in oil drilling. Parts such as tools, inner walls of pipes, inner holes of pump valves, and narrow spaces are being repaired. Huirui’s latest second-generation inner hole laser cladding head can be applied to industrial parts with a minimum inner diameter of the pipe wall ≥ 30mm. It adopts a shock-proof and sealed design, has stable functions, and has high deposition efficiency.

Repair name: Oil drilling tools
Basic situation: The main shaft of the oil drilling tool is severely worn due to erosion, so the inner hole is used to repair and strengthen the inner wall.
The range of repair and strengthening materials is relatively wide, including iron-based, nickel-based, cobalt-based, ceramics, etc.
