Abstract
A pulsation control device is constructed at least partially of a composite carbon (and/or other fibers)/epoxy exostructure having an oblong cylindrical or spheroidal shape, optionally with metallic portions or reinforcements, together with a non-metallic polymer non-load sharing liner. A pressure drop tube preferably extends from an opening through an exterior wall of the body into an interior space within the body.
Claims15
A pulsation control device, comprising:
- a body constructed of a composite, non-metallic material and having a polymer liner, the body forming an annular cylinder with a plurality of dome-shaped ends and sealing fluids under pressure inside, the body formed with identical half structures each including dome-shaped or elliptical end structures at either end of a center portion;
- and
- a metallic inlet nozzle and a metallic outlet nozzle each within an opening in one of the dome-shaped ends of the body, the metallic inlet nozzle and the metallic outlet nozzle permitting fluid flow into and out of the body.
A pulsation control device, comprising:
- a body constructed of a composite, non-metallic material and having a polymer liner chemically compatible with oil and gas industry drilling fluids, the body forming an annular cylinder with a plurality of dome-shaped ends, the body formed with identical half structures each including a dome-shaped or elliptical end structures at either end of a center portion;
- and
- a metallic inlet nozzle and a metallic outlet nozzle each within an opening in one of the dome-shaped ends of the body, the metallic inlet nozzle and the metallic outlet nozzle permitting fluid flow into and out of the body and each including integrated a plurality of nozzle flanges that provide a plurality of mounting locations for both a plurality of support structures and a plurality of lifting lugs.
