HPHT Control Choke

Metal seals and nonelastomeric seals

Cameron HPHT-rated chokes provide high performance and reliability in sour service, with temperatures up to 400 degF [204 degC] and pressures up to 20,000 psi.

Our chokes are used in high-CO2 and H2S, high-chloride, and high-temperature environments and employ modern corrosion-resistant alloys (CRAs) to provide trouble-free service life. Low-alloy steel bodies are lined with nickel alloy 625 in a weld cladding process, providing a thick, impervious layer of the CRA bonded to the base material. The other components employ similar corrosion-resistant alloys in their construction.
