Description
Corrosion-proof electrowelded pipes
Electrowelded pipes from corrosion-resistant staly, intended for production of pipelines and various designs, produced according to GOST 11068-81 belong to this group of steel products.

The range of pipes corresponds to GOST 11068-81.

On length of a pipe have to produce:

measured length - from 5 to 9 m;
measured length from the rest - no more than 10% (on weight) pipes of unmeasured length;
multiple measured length - to 9 m and with an allowance for each cut on 5 mm which enters each multiple length;
multiple length from the rest - no more than 10% (on weight) pipes of unmeasured length;
unmeasured length - from 1,5 to 9 m.
Maximum deviations on length of pipes of measured and multiple length should not exceed +15 mm.

The theoretical weight of 1 m of a pipe (m), kg, calculate on a formula:

M = psng (Dn-sn)/1000, where

Dn - the nominal outer diameter of a pipe;

Sn - the nominal thickness of a wall of a pipe, mm;

g - density of metal, g/cm3, depending on steel brand.
