Tubing
Production tubing — non-upset (NU), external-upset (EUE) and high-seal types — for oil extraction. Selected by diameter, steel grade and standard.
Tubing NKT, NKV and NKM with Delivery Across Russia
Burmetsnab supplies production tubing for oil and gas extraction, injection operations and well service: selection by diameter, wall thickness, steel grade and standard.
Production Tubing NKT
Standard production tubing with threaded connections and coupled ends. Manufactured from alloy steel to GOST 633-80. Used for lifting oil and gas and for injection of working fluids to depths of up to 5,000 m. Steel grades D, K and E ensure reliability across a wide range of operating conditions.
NKM tubing with a high-integrity metal-to-metal seal is designed for service at pressures up to 50 MPa. T-200 internal coating protects against corrosion and scale at temperatures up to 200°C. Used in demanding conditions: high pressure, aggressive fluids and thermal loading.
Production Tubing NKM
Production Tubing NKV
NKV tubing with externally upset ends provides increased threaded connection strength. The upset ends increase thread load capacity by 20–30%. Used in wells with high loads and aggressive environments. Steel grades K, E, L, M.
