WASHOVER AND CUTTING TOOLS
Marine Casing Cutter
Marine casing cutter is one of tools which cuts the casing internally. It uses water horsepower to drive cutters work, it has structure reasonable and convenient maintenance, faster cutting speed. When cutting multi-layer non- concentric casings, It could bear drastic shaking. Strong cutter arms can extend to 5 times as much as body diameter, so that get max stability performance under all kind of disadvantage cutting condition( including hard point, concentric, cutting discontinuity), such as 13-3/8" marine cutter body diameter is just 11-3/4", but the max cutting range of pipes reach 60".

lease specify special requirements.
Lifting Cap
Lifting Cap is a special tool for lifting drilling tools in oil,gas and exploration drilling project.
Specification: All sizes.
Mud Bucket(Saver)
The mud bucket issued for tripping the drill string, preventing polluting the platform by mud splash because of blocking when removing the drilling tools,to recycle the drilling fluid. The advantages are safe,convenience,clean and economy.
Specification:For 2 3/8"~ 6 5/8" DP.
Roller Kelly Bushing
Roller kelly bushing is one of the necessary tools for oil drilling operation, which is fixed at the big bushing to pass the torque to the down hole drilling tools.
According to the driving mode, it could be divided into square drive type and pin drive type. According to the kelly, there are square kelly bushing and hexagonal kelly bushing. It mainly consists of roof cover, bottom cover, axls pin, roller, fastening bolt and stals, etc.
There are four pieces of roller in the bushing which have needle bearing inside the rollers and fastened between roof and bottom cover by and pin and seals at both ends of rollers to prevent the drilling fluid from percolating. There is a stop pin fixed in the seal body to prevent rotating.
The axles of roller is fixed by four pieces of bolt M38 which tightening torque is 2KN-m. There are four hexnuts fixed the top of four large bolts with the covers tightly to avoid loosing.
