OIL AND GAS FIELD EQUIPMENT

Used for sealing oil and gas wellheads, and modes control during drilling and operation.

Wellhead and Christmas tree equipment

Wellhead equipment ОКК1, ОКК2, ОКК3 manufactured by the plant is intended for hanging casing strings with sizes 426 (16.3/4''), 324 (12.3/4''), 245 (9.5/8''), 178 (7''). 168 (6.5/8''), 146 (5.3/4''), 140(5.1/2'') and separation of space between strings, performance number of process operations, installation of blowout preventing equipment (in the process of drilling) and Christmas tree equipment (during its operation), and is designed for working pressures 14, 21, 35, 70, 105 МPа (2,000, 3,000, 5,000, 10,000, 1,000 psi).

Christmas Trees for oil and gas wells are intended for sealing wellheads, inspection and control of their operation mode as well as for performing various process operations at working pressures 14, 21, 35, 70 and 105 МPа (2,000, 3,000, 5,000, 10,000 and 15,000 psi). Christmas trees are manufactured of the following types: АF type where tubing is hanged in mandrel hanger, АFК type where tubing is hanged in adapter flange and АFа type having additional tubing head which provides hanging two rows of concentric tubing strings; moreover there may be either with duplicate gate valves on side outlets of Christmas tree and tubing head or not.

Shutoff equipment

Steel through conduit gate valves are intended for use as shutoff valves for oil and gas wells. They have bores 50, 65, 80 and 100 mm (2.1/16'', 2.9/16'', 3.1/8'' and 4.1/16''), working pressures 14, 21, 35, 70 and 105 МPа (2000, 3000, 5,000, 10,000 and 15,000 psi).

Gate valves with lower balancing stem and rising spindle having forced ZMS grease injection between gate and seats, manually operated, intended for installation to Christmas trees or mounted on pipelines as shutoff valve to fully shutoff working medium flow on oil or gas wells. Bores: 50; 80 mm (2.1/16'', 3.1/16''), working pressure: 70 МPа (10,000 psi).

Gate valves with rising spindle of ZMVSH type is intended for use as shutoff valve on oil or gas wells. Bore 65 mm (2.9/16''), working pressure 35 МPа (5,000 psi).

Hydraulic powered gate valves of ZMG type is intended for remote control of working medium flow on oil or gas wells as well as used in manifolds. Bore 80 mm (3.1/16''); working pressures: 35, 70 МPа (5,000; 10,000 psi).

Blowout preventing equipment

Manifolds are intended for piping shank part of blowout preventing equipment on oil or gas wells during their construction or repair and serves for wells control under oil ingress to ensure works safety, preventing blowout or open spouting, subsurface and environmental safety. Bore: 80 mm (3.1/16''), working pressures.35; 70 and 105 МPа (5,000; 10,000 and 15,000 psi). Diagrams in accordance with GОSТ 13862-80.

Manually operated perforation gate is intended for performing shooting-through works and sealing wellhead. Bores: 130, 150 mm (5.1/8'', 6''), working pressures: 21, 35 and 70 МPа (3,000, 5,000 and 10,000 psi). Connection dimensions correspond to GОSТ 28919 and RD 26-16-40-89.

Also, JSC Konotop Valves Plant performs servicing and repair of gate valves for working pressures 14, 21, 35, 70 and 105 МPа (2,000, 3,000, 5,000, 10,000 and 15,000 psi) of JSC Konotop Valves Plant manufacture.
