Frac StacksStinger supplies and services frac stacks that temporarily replace the production wellhead during pressure pumping operations. In addition to protecting an operator’s production wellhead from the effects of pressure and abrasion during the fracturing process, our frac stacks allow high pressures and volumes of proppant to pass to the formation for maximum well response.

To minimize operating torque, our valves are available with quick turn hand-wheel or hydraulic actuators. The quick turn design incorporates a ball screw assembly that allows easy operation under pressure, even for large bore systems.

SpecificationsStinger offers three types of assemblies:

· Special pin assembly

· Screw-on assembly

· Upgrade spools

Frac StacksBall Catchers

As with any flow-back operation, particularly those of gas producing wells, the number of shut-ins relies heavily on the type of equipment that can handle high pressures. Disruptions in the flow stream greatly reduce the efficiency of any operation.

Flowing back after fracturing is especially problematic due to the composition of mud, balls, and sealers that comes up. Without the proper equipment, manifolds and other surface equipment can quickly clog resulting in costly down time.

To eliminate these problems, Stinger ‘s ball catcher traps frac balls with outer diameters up to 3-7/8”. Handling working pressures from 5,000 to 15,000 PSI, these durable apparatuses significantly reduce flow-back disruptions after fracture.

Pressure Ratings:

· 4-1/16” (103.2mm) x 69 MPa (10,000 psi)

· 4-1/16” (103.2mm) x 103.5 MPa (15,000 psi)

Frac StacksManual and Hydraulic Frac Valves

· Metal-to-metal sealing at the gate-to-seat

· Available studded or flanged

· A truly symmetric bi-directional design

· A metal-to-metal stem backseat on both the upper stem and tail rod to permit replacement of either stem packing with the valve cavity under pressure

· Design meets API 6A and PSL 3. All materials meet and exceed specified criteria including NACE MR-01-75 criteria

· Valve Sizes

· 4-1/16” (10K, 15K)

· 5-1/8” (10K)

· 7-1/16” (5K, 10K, 15K)

· Temperature rate is -40°C to 120°C

· Material class: DD (Sour Service)

· Ball Screw is used for most of manual valves, which reduces the required work to operate the valves to less than 1/3 of that required to operate the conventional design. The ball screw uses “rolling” friction in place of “sliding” friction. The low torque and reduced number of turns allows the valve to be stroked in less time with less effort than conventional high pressure valve designs.
