Are you interested in GOST 631-75? Supplier Evek GmbH offers to buy drill pipe with drop ends and couplings to them at an affordable price in a wide range. We provide product delivery anywhere in the continent. The price is optimal.

General Terms

GOST 631-75 is applied to steel seamless pipes with upset ends and couplings to them and also to pipes with upset ends and tapered stabilizing straps used for drilling wells.

The assortment of the considered pipe versions includes the following types:

with inside-out ends and couplings to them;

with external spigots and couplings to them;

with inwardly extruded ends and tapered stabilizing belts;

with outwardly extruded ends and tapered stabilizer belts.

Pipe sizes must conform to the values given in the following table:
