Drill-pipe slip

Drill-pipe slips are produced in compliance with TU U 28.6-30895845-003-2004 standards, and are used for screwing together and apart of case, pump-compressor and drilling pipes in jaws of pipe wrenches and pipe-grabbing units. Drill-pipe slips produced by our Company possess a number of distinctive features as compared to analogue ones: improved performance characteristics and increased failure-free operation time.

Structurally, according to technical requirements, the drill-pipe slips are divided into two types: radial (fig. 1) and flat (fig. 2).

Advances technology developed by our specialists and the serial production give us the possibility to minimize the selling price. Slips are made of structural alloyed steel according to GOST 4543-71 standard (equivalents – AISI 5120, SAEJ 404). Location of slip teeth accurately repeats the shape of pipe and pipe connection surfaces, withstands centering at high torsional moment, eliminates slippage, deformation and crumpling of pipes. Geometrically accurate production and following calibration of slip bases provide for installation into the wrench jaw slot with fit tolerance of 0.03 mm and eliminates the probability of lateral play or slip damage.

Carbonization at 0.9-1.2 mm depth (cement stabilization process) with subsequent tempering and abatement result in austenite-martensite structure with equal content of these phases and ensure strengthening of slip surface up to HRC 59-62, and slip core – to HRC 39-42. Such technology helps to avoid some problems connected with operation of wrenches and pipe-grabbing units, namely:

     1. In case of impulse load the transverse facture is excluded;
     2. Slip destruction and penetration of its fragments into the well are excluded;
     3. The operating part of a slip uniformly wears out, without any cracking, disintegration or fractures.

Test sampling of details from every batch is performed in order to find any hidden internal defects with the help of induced current and guarantees the high quality of our products.
