Threaded couplings and coupling stock used to connect oilfield tubing and casing strings.
Material chemistry and mechanical properties are checked before machining. Thread form, dimensions and surface condition are controlled during production, followed by final inspection according to the ordered tubing or casing standard.
Connecting tubing and casing joints in oil and gas wells. Casing strings support the borehole and cemented well structure, while tubing conveys produced or injected fluids.
