Boring pipes TBSU in accordance with GOST P 51245-99, Boring pipes SBTM in accordance with GOST 7909-56,

The offered boring pipes can be used with all types of the drilling rigs and installations (for example, URB, 2A2, Ziff 650, Ziff 1200, special design bureau - 4, UBV, the FOREHEAD, PBH) applied in search, prospecting drilling, construction at observance of the following conditions:

• in case of building and spusko-raising of a column through a rotator, diameter of its channel through passage there has to be more than diameter of the lock of a boring pipe;
• in the absence of the limiter (regulator) of a torque on a rotator, its maximum value should not exceed the recommended moment of an inhaling of a threaded connection of a pipe;
• if the maximum moment of a rotator is less than recommended moment of an inhaling of a threaded connection, the last is provided with the special device (truborazvoroty).

The real pipes are provided by GOST P 51245-99. The standard extends to the smooth-bore steel boring pipes with the welded locks intended for drilling of wells by searches and investigation of solid minerals, drillings of wells under water at engineering-geological researches and construction, a kolonkovy and beskernovy way, hard-alloy and diamond crowns and chisels of all views, including with application bottomhole gidro-and pneumatic impact tools.

Pipes boring prospecting from the ends (SBTM) landed inside are applied at prospecting kolonkovy drilling up to 2000 m in depth.
Pipes can be delivered complete with locks and couplings.
Pipes are made of steel of group of durability "To" (Steel 36G2S) of the coupling from state standard specification 4543-71 steel 40XH.
