Compared to GOST 8696, GOST 10704, GOST 10705, GOST 10706 in this standard:

— introduced a classification of pipes according to the classes strengths:

— supplemented by a number of pipe sizes the outside diameter and wall thickness;

— equipped with two precision-length of tubes: normal and high;

— added the possibility of testing of pipes for impact strength and non-destructive testing;

— added the possibility of manufacturing pipes with the definition of carbon equivalent, free from scale, surface, trim ends.

6.3.8 Mechanical properties of the tube delivery group E determined by agreement between the manufacturer and the customer.

6.4 Technological properties

6.4.1 Pipe vchs delivery groups A and b, of an external diameter to 152,0 mm inclusive, the wall thickness of not more than 15% must be able to withstand the technological test of flattening.

Flattening of samples is carried out before the distance between clusively planes equal to 2/3 of the outer diameter of the pipe.

6.4.2 According to customer’s requirement pipe delivery groups, and must withstand one or more technological tests on the distribution, bend, flattening or static bending of welded joints indicated in table 4.
