The tubing is normally used to extract liquids and gas from oil/gas-bearing formations, inject water and compressed air (gas) into oil and gas wells, and perform various types of well reconditioning and workover operations. These are pipes threaded at both ends and complete with a coupling screwed on one end. The tubing is manufactured with plain or externally upset ends and box coupling, and the following options or their combinations can be available:• Standard tubing• High-strength tubing• Corrosion-resistant tubing (Grade 1Cr)

• Cold-resistant tubing• Higher operational reliability tubing• Improved permeability tubing• Type F-3,2 thread-connection tubing• Type T100, T100NV premium class high-reliability pressure-tight

threaded connections tubing (with the possibility to make-up with type NEW VAM and VAGT threads)

• Special-purpose tubingThe tubing is manufactured on high-technology equipment at the Pervouralsk Pipe Plant. All seamless tubing production phases fully comply with ISO 9001, API Specification Q1 and API Spec 5CT.
