The C-22 Casing Heads have a straight bore bowl design The C-29 straight bore casing heads are based on the same reliable design as the C-22 with exception that the bowl is two inches onger, which permits the acceptance of the minimum-deflection C-29 Casing Hanger. The C-22 Casing Heads have a straight bore bowl design The C-29 straight bore casing heads are based on the same reliable design as the C-22 with exception that the bowl is two inches longer, which permits the acceptance of the minimum-deflection C-29 Casing Hanger.

Slip-type casing hangers provide a method to transfer the weight or tension load of a casing string to a casing head or spool. 

C-22 Casing Hanger, C-29 Casing Hanger and C-21 Casing Hanger

The Casing spool has a top bowl to accommodate the casing hanger. The spool also has a bottom bowl with a pack off seal and a flange or lamp hub for mounting it on top of a casing head or previous spool. 

C-22 Casing Spool and C-29 Casing Spool

The Tubing Head is the top spool on a surface wellhead assembly. TC & TCM Tubing Heads TC Tubing Heads are a straight bore bowl design, for single and multiple completion in working pressure through 15, 000 psi and in sizes to meet all multiple completion requirements.

Tubing hangers are installed in the top bowl of a tubing head. Tubing hangers both suspend the
tubing and provide a primary annulus seal between the tubing and production casing.

The Delta gate valve has been proven in critical oil filed services throughout the world. 

C-Model Gate Valve and TC Model Gate Valve

Delta Hydraulic Actuator (DHAV) is designed to be used in conjunction with Delta valve bonnets to provide open and close control for major brands of API 6A through conduit reverse acting gate valves fitted to oil and gas wellheads and production flow lines.

The solar panel uses the sunlight energy to compress enough air pressure to operate the pneumatic SSV. This technique allows the equipment to be used in an unattended or isolated location. 

Delta gate valves offer the ultimate in dependable service for steam, air, gas, oil vapor and high pressure installations. All have straight-through ports to assure minimum turbulence, erosion and resistance to flow. 

Delta Globe Valves are highly efficient for services requiring frequent operations and throttling when pressure drop across the valve is about 20% of inlet pressure.

Check valves are automatically actuated. They are opened and sustained in the open position by the force of velocity pressure and closed by the force of gravity. Seating load and resultant tightness is dependent upon back pressure.

Delta Ball Valves are manufactured to industry FIRE SAFE standards to ensure safety in the event of fire. If failure of the primary seal occurs, the ball contacts the secondary (metal) sealing surface to provide an emergency positive seal.
