Sucker rod elevators are manufactured and tested according to API Spec 8C. These elevators are made from high-quality heat-treated alloy steel for strength and durability and the rated load ability is 25 tons. It used for hosting the drilling and production equipment.

FC valve 

1. Full-bore design, effectively eliminate the pressure drop and eddy current, slow flow of solid particles in the valve.
2. The unique sealing, make the switch torque greatly reduced
3. Between bonnet & body and gate & seat are adopt metal to metal seal
4. Between gate and seat are adopt metal to metal seal, Surface spraying (heap) welding hard alloy , has good abrasion resistance, corrosion resistance.
5. Seat ring is fixed with plate, keep well steady
6. Stem has back seal structure so as to replace seal ring of stem with pressure
7. There is seal grease injection valve on bonnet side so as to repair seal grease , and provided seal and lubricate performance of gate and seat
8. It is match with all kind of pneumatic (hydraulic) actuator as customer's requirements

Expanding gate valve
1. Gate is fission expanding structure
2. Realizing low torque or low wear during switch
3. Between bonnet and body are adopt metal to metal seal 

Casing Centralizer is a device used to place the casing at the center of the hole so as to improve the efficiency of the cementing. It is an important device because if the Casing Centralizer touches the formation at any part of the hole, then cement slurry does not pass through the area of the contact resulting in a poor cementing job.

Accumulator unit for BOP stacks is a very important equipment which controls BOP stacks and gate valves controlled by hydraulic pressure especially in drilling and workover operations. It is necessary to accurately operate and maintain the hydraulic control system. It consists of remote control system, driller’s panel, air cable (except electrical type), pipe rack (electrical warming system available for cold area), high pressure manifold, protection room, etc.
