COILED ROD
- Brand:
- Type:
Coiled Rod is a kind of steel sucker rods with semi-elliptical or round sections. The quality alloy steel rods are manufactured with advanced technology, showing strong tensile strength, high flexibility and better weldability. Its mechanical property is equivalent to those of API grade D rods or SM, SMR, SU and SUR special-purpose rods . Coiled Rods in different sizes can be welded together through advanced welding procedures.
Benefits in contrast with conventional rods:
1. Less tubing-rod eccentric wear;
2. Less drag force when RIH or POOH .with improved pump efficiency;
3. Lighter in weight in comparison with conventional sucker rods of same sizes;
4. Minimized rod string break accidents with enhanced reliability ;
5. Improved trip speed and decreased labor intensity;
The steel Coiled Rod finds wide applications in horizontal, directional, slant or deep wells, demonstrating an ideal solution for the above special applications and with annual rod consumption of over 1 million meters.
The Coiled Rod is complete with unique supporting devices for use with PCP in offshore applications。
