seamless tubing -...

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 couplings, and the following options or their combinations can be available:• Standard tubing• High-strength tubing• Corrosion-resistant tubing (steel class 1, 3, or Cr 5%)

• Cold-resistant tubing• Higher operational reliability tubing• Tubing with enhanced passage properties• Type F-3,2 thread-connection tubing• Premium gas-tight threaded connections for tubing ChT-VT and ChT-VTm1 (modification for make-up with NEW VAM and VAGT)• Special-purpose tubingThe tubing is manufactured on high-technology equipment at the PNTZ Oil Pipe Rolling Plant Finish Center. All seamless tubing production phases fully comply with ISO 9001 and API Specification Q1, API Spec 5CT, GOST R 53366, GOST 633-80.

The casing pipes are used to control wellbore walls during well construction and operation. These are pipes threaded at both ends and complete with a coupling screwed on one end.The casing tubes are seamless tubes complete with couplings, and the following options or their combinations are available:• Standard• High-strength tubing• Corrosion-resistant tubing (steel class 1 or Cr 3%)

• Cold-resistant tubing• Higher operational reliability tubing• Premium gas-tight threaded connections for casing ChT-VСThe casing is manufactured on PNTZ and ChTPZ high-technology equipments. All seamless casing manufacture phases fully comply with ISO 9001 and API Specification Q1, API Spec 5CT, GOST R 53366, GOST 632-80. 100% of casing and tube couplings are subject to nondestructive control.
