Wellhead and X-Mass Tree are the primary pressure controlling equipment of any oil well. The arrangement of the Wellhead and X-Mass Tree items are customized to suite specific customer requirements and site conditions.

Equipments are designed to the Pressure Ratings of float shoe and Temperature Ratings of K, L, P, R, S, T, U and V, PSL Levels 1,2,3 and 4, Material Classes AA, BB, CC, DD, EE and FF as per API 6A and also meeting Sour Service in Compliance with NACE Standard MR 01- 75.
Casing Spools have full opening vertical bores complying with API 6A standard. They accept the interchangeable, field replaceable bit pilots which provide bit guidance for use over smaller sizes for casing

The hanger is an automatic suspended-and-seal unit. It utilizes a metal hinge and a simple integral latch pin. It can be wrapped around the casing and lowered through preventers. Upon reaching the bowl in the casing body, it grips and suspends the casing string.

Crossover Tubing spools are similar to regular tubing spools, but the dimension of the lower end flanged connection provide one service pressure ...
... rating less than the outlet and upper end flanged connections.

60 years of Worldwide service in oil, gas, chemicals, water, slurry and multi-products has confirmed the Pow-R-Seal as the most trusted gate valve, where safety and reliability of sealing are critical.

The positive, mechanical seating force of the drill rotary table seals holds with zero leakage through conditions of vibration, pressure change and temperature excursion. The rigid, cast steel body resists pipeline bending moments.

TFE seals on both faces of the valve assure drop-tight sealing even at low differential pressure, while metal-metal contact between the seals and gate mechanism provide FIRESAFE shut-off. Optional all-metal seals are also available for service to +1,000F (+538C), where leakage rates comply with API 6D, Supplement 2.

WKM Pow-R-Seal Gate Valves are the choice of LIQUIDS PIPELINE OPERATORS because they tolerate the wax, paraffin, abrasives and multi-product flow that causes problems in other valve designs.

The WKM Saf-T-Seal gate valve is a simple, yet rugged and reliable, through

conduit gate valve. It utilizes two floating seats to provide a complete seal

with the gate. Each seat contains a metal seat face plus a peripheral seal. The full bore design has the same pressure drop as an equivalent length of

pipe and allows passage of all types of scrapers (drill pipe joint).
