Injector Spare Parts for sale


Suitable for large-diameter heavy-duty CT drilling and other operations of extra deep wells;
Key parts of top brands in the world, with reliable performance, ensuring the product quality and operation safety;
Manufactured strictly according to DNV and API standards.

Synchronizing mechanism designed to achieve the synchronous operation of the chains under high load;
Quick-change grippers (National Invention Patent);
External traction cylinders to offer higher traction force;
Unique design of skate to make the chain bearings enter the gripper section stably, which extends the service life of coiled tubing, grippers and the bearings.
Special traction bearings (National Invention Patent), which need neither disassembly for inspection nor lubrication, reducing the down time greatly;
Superior slow speed control. The minimum running speed is 0.06m/min (2.3in/min) which meets the speed requirements of high-precision compound operations such as drilling and workover.
Both the grippers and the gripper carriers are carbonized to achieve high surface strength, making the service life up to 2000 hours.
High matching rate between the motor power and gearbox power reduces the power loss. The system is designed to have an extra lifting capacity of 10% to ensure strong power for operations.   
Traction pressure protection to ensure the safety of operations against the loss of power;
Anti-fall device to ensure the safety of operations at height.

Tubing counter or sprocket encoder to monitor the tubing speed and depth;
Explosion-proof camera to monitor the injector and stripper in real-time;
Electronic load cells, hydraulic load cells or combination of electronic and hydraulic load cells.
100” or 120” gooseneck to meet the operation requirements of different tubing sizes;
Gooseneck load display, to monitor the gooseneck load in real-time so as to avoid the risks caused by over-high back pressure of the coiled tubing reel.
