flow couplings

Flow couplings are coupling OD tubing ID components installed in the production string above and below production equipment installed in the tubing. These products provide a thick wall member in an area subjected to internal fluid turbulence created by high velocity flow entering and exiting tubing restrictions created by completion products such as subsurface safety valves, landing nipples and side pocket mandrels installed in the tubing string. This thick walled tubing member resists internal erosion caused by this turbulence. Tejas Tubular is one of the largest manufacturers of API OCTG products in North America. All of our flow couplings are manufactured from the same high quality API seamless collar stock as our tubing and casing couplings, and are made in accordance with API specification 5CT latest edition, with full traceability. All Tejas Tubular flow couplings are made with the Tejas Tubular quench and temper process in our own heat treat lines.
