GOST 50278-92

JSC "Uraltekhmarket" offers Pipe rolling, appropriately GOST 50278-92.

Drill pipes are used for lowering in the borehole and lift rock cutting tool, the transmission of rotation, creating axial load on the tool, a supply of washing fluid or compressed air to the working face.

Distinctive features

Drill pipes are joined together using a drill with a special lock thread. The ends of the tubes thicken to increase their strength, outer, inner or combination planting.

Drill pipe the Pipe Metallurgical Company are made by welding of the nipple and coupling of the tool joint to the planted ends of the body of the drill pipe. For each stage of production uses a special tracking system that ensures continuous compliance with quality and required characteristics of 100% drill pipe.


This standard applies to seamless steel pipes with upset ends and welded them locks designed for the construction of oil and gas wells.

Climatic conditions of application range from 11 to 1112 according to GOST 16350.

Locks for stud manufactured in accordance with GOST 27834.

 

BASIC PARAMETERS AND DIMENSIONS

Drill pipes with welded locks should be manufactured with three types of upset ends:

PV - with inner landing;

PK - combined with planting;

MON - with outdoor planting.

In accordance with the order pipe of all types shall be manufactured with locks, having a rectangular or tapered shoulder under the Elevator, and with right-or left-hand thread (figure 1).

G - identification band for locks with left-hand thread

Figure 1

1.2. Assortment of finished drill pipes with welded locks shall be as specified in table. 1 and 2.
