Overview:Reliable performance, A487/CA15 cast valve body, low carbon steel forged bonnet, low operating torque, valve body/bonnet metal seal, lubricated fittings, easy maintenance, simple design to ensure low cost, flange or threaded outlet.

Overview:The C-22 / C-29 Casing Heads have a straight bore bowl with 45° landing shoulder design which avoids damage to sealing areas by drilling tools and prevents test plug and bowl protector wedging problems when pressure is applied. C-22 / C-29 Casing Heads are normally furnished with threaded outlets and studded outlets are available upon request. Bottom connections can be furnished threaded or slip-on for welding. C-29 Casing Heads are based on the same reliable design as the C-22 with exception that the bowl is longer, C-22 which permits the acceptance of the C-29 casing hanger with larger load capacity for deeper drilling.

Overview:Split wellhead adopts single-layer or double-layer casing head, the bottom is welded and connected with "O" ring, and it can be equipped with a round bottom support disc. The secondary seal can adopt "BT", "P-type", "BES" and other types of seals. The seal is safe, reliable and easy to operate. The tubing hanging adopts the mandrel type, which relies on the extrusion of the top wire to excite the rubber seal. The valve on the Christmas tree uses a dark rod and a sealed structure behind the valve. It has the characteristics of small switching torque and easy online maintenance.

Overview:BENOSTON's single seat flat gate valves are designed in accordance with API 6A and NACE MR-01-75, with strict quality control in compliance with APIQ1. This type of flat gate valve includes flange end and threaded end two structural forms, and can provide both manual and hydraulic operation types. Large diameter products with ball screw design. Easier to operate.

Overview:The integrated wellhead tree has a monolithic structure, which reduces leakage points and increases safety.

Overview:Double seat flat gate valves manufactured by BENOSTON are designed in accordance with API 6A and NACE MR-01-75, with strict quality control in compliance with APIQ1. This type of flat gate valve includes flange end and threaded end two structural forms, and can provide both manual and hydraulic operation types. Large diameter products with ball screw design. Easier to operate.

Overview:Benoston manufactures a variety of slip casing hangers, including C-21 casing hangers, C-22 casing hangers and C-29 casing hangers

Overview:The tubing hanger at the wellhead of the electric submersible pump is provided with a cable through hole, a capillary cable hole, and a downhole safety valve control pipeline through hole.

Overview:The API6A choke valve from BENOSTON is a multistage pressure relief regulator that can be used to control the flow and pressure of high temperature, high pressure and solids containing fluids. Using needle or sleeve cage structure design, the formation of front and rear multi-stage choke valve, spool and seat with hard and soft seal, the sealing surface and throttle surface are separated, improve the throttle capacity and sealing reliability of the valve, with reliable sealing, low noise, small vibration, throttle cutoff pressure reduction, switch light and flexible advantages. The valve is especially suitable for throttling and cutting off under high pressure. Under high pressure conditions, with decompression function, long service life.

Overview:The C-22 / C-29 Casing Spool are a straight bore bowl with 45° landing shoulder design. Bottom preparation can be the PE/BG as in the picture，“OO” bottom ( for below 5000 psi application) or double "P" seal bottom. The BG preparation allows the use of reducer bushings "PE" (Pressure Energized). Outlets are normally threaded; optional studded / flanged outlets are available. C-29 Casing Spools are based on the same reliable design as the C-22 with exception that the bowl is longer. This permits the acceptance of the C-29 casing hanger with larger load capacity for deeper drilling.

Overview:The equipment of the double-tube wellhead can perform the completion of two wells at the same time in one well. Double-tube tubing hangers ensure that any string can be lifted independently. The double-tube integrated oil production tree ensures that two oil pipes can simultaneously produce oil without ensuring that they penetrate each other. Satisfy different working conditions, work safely, and seal reliably.

Overview:BENOSTON offers hydraulic flat gate valves in sizes ranging from 1 13/16 "to 7 1/16" with pressure ratings ranging from 2,000psi to 15,000psi. Designed and manufactured in strict accordance with API 6A and API Spec Q1 standards, the valve is forged or cast AISI 4130/4140 low alloy or AISI 410 SS steel, and the actuator design is safe and suitable for all kinds of gate valves.

Overview:The metal seal of the wellhead is sealed with the "RCMS" metal seal, which is safe and reliable, and rotates; The tubing hanger and casing hanger are of the mandrel type, and are sealed with "XEMS" metal, which is reliable in sealing and strong in corrosion resistance; The tubing hanger extends the neck and is sealed with "SBMS" metal. The nominal pressure of the metal-sealed wellhead can reach 20000psi, and the working temperature: -18 ℃ ~ 346 ℃ (Y).

Overview:TC and TCM Tubing Heads are a straight bore bowl with 45° landing shoulder design which avoids damage to sealing areas by drilling tools, and prevents wedging of the tubing hangers, bowl protectors and test plugs. the secondary seal for the last casing pipe can be an integrated “OO” seal type or the plastic injection type, but also accepts reducer bushings "4-O" and "PE" (Pressure Energized).
