Electro welded straight-line-seam pipes

Electro-Welded Longitudinal Steel Pipes (GOST 10704-91)

Electro-welded longitudinal steel pipes (GOST 10704-91) are made for:

Random length:

For the diameter up to 30 mm - not less than 2 m;
For the diameter of more than 30 and up to 70 mm - not less than 3 m;
For the diameter of more than 70 and up to 152 mm - not less than 4 m;
For the diameter more than 152 mm - not less than 5 m.

If requested by the client. pipe groups A and B (GOST 10705) with the diameter of more than 152 mm can be produced with the length of not less than 10 m. and pipes of all groups with the diameter up to 70 mm can be produced with the length of not less than 4 m;
Indexing length:

For the diameter up to 70 mm - from 5 up to 9 mm;
For the diameter of more than 70 and up to 219 mm - from 6 up to 9 m;
For the diameter of more than 219 and up to 426 mm - from 10 up to 12 m.
Pipes with the diameter more than 426 mm are produced only of random length. As agreed with the client. pipes with the diameter of more than 70 and up to 219 mm are supposed to be produced with the length from 6 up to 12 m;

Example of the marking designation: pipes with the outside diameter of 76 mm. wall thickness of 3 mm. indexing length. II class length accuracy. made pf steel grade СтЗсп. within group B (GOST 10705-80):

76x3x500011 (GOST 10704-91).
Pipe В-СтЗсп (GOST 10705-80) (GOST 10705-80)
