Choke and Kill Manifold
DOYLES Choke and Kill manifolds are manufactured to meet your specific requirements. From simple low pressure to extreme sour gas service, manifolds can be designed with any number of fixed chokes, manually adjustable chokes and automatic chokes with a working pressure of 3,000, 5,000, 10,000 or 15,000 psi.
All components, including the items described in this paragraph, meet H2S specifications and all welded components receive post-weld heat treatment in accordance with approved procedures.
Welding is performed by qualified personnel, in accordance with qualified procedures. All welds are full penetration welds and conform to ASME Section VIII. In addition, all welds receive visual, magnetic particle and ultrasonic inspection to ensure the utmost quality and performance.
FEATURES
- All components are manufactured in accordance with API spec 6.
- Choke manifold assembly manufactured in accordance with API spec16C.
- Flow fittings are suitable to H2S service as defined by NACE MR0175.
- Fittings include buffer chambers, spools, crosses and tees.
- Telescoping and non-telescoping skids can be fabricated to fit your manifold assembly.
- Safety rails can be ordered to conform to safety requirements.
- Choke manifold mounted to the skid with custom-manufactured u-bolts FOR strong gripping power.
- Slotted u-bolt base beneath the buffer tank allows the buffer tank to be pulled straight back without lifting it out of any pipe-style saddles. This eliminates lifting equipment, greatly reducing down time.
