The supplier guarantees the observance of the assortment of delivery of products, ensures their timely transportation to the address indicated by the customer.
GOST 24301−93 concerns, in particular, pipes of round cross section, which are made of foundry bronze alloys of certain grades. It is established that the recommended dimensions of the external diameter and wall thickness of pipes should correspond to the following values: diameter — from 40 to 200 mm, wall thickness — from 8 to 40 mm. The length of pipes produced by standard technology can not be less than 400 mm, and more than 2000 mm. The other sizes are manufactured according to individual orders.
Buy cast pipes, made of foundry bronze alloys, at economically favorable prices of the manufacturer offers the company Elektrovek-steel. The supplier guarantees the observance of the assortment of pipes supply, ensures their timely transportation to the address indicated by the customer.
Cast pipes according to GOST 24301−93 in Russia and CIS countries are made of the following bronze grades:
- BRSTS 5−5-5;
- BRSTS 3−12−5;
- BROCSN 3−7-5−1.
The raw materials must have a chemical composition that complies with GOST 613 standards, contain no shells and foreign inclusions, cracks and other surface defects that extend more than half the tolerance. Tolerances on ovality of pipes are also established in the same limits. The specified limit deviations are established for two groups of products. For the first group, the ovality tolerances, depending on the diameter of the bronze tube, range from +0.6 and -0.1 to +1.2 and -0.4 mm. For pipes of the second group — from +1.0 and -0.9 to ± 2.0 mm, respectively.
Similarly, tolerances for the thickness of the pipe walls are established. The first group is from +1.0 and -0.7 to +2.0 and -1.5 mm, the second group from ± 1.0 to ± 2.0 mm.
The mechanical characteristics of cast bronze pipes are given in the table:
|Alloy Brand||Limit of time resistance, MPa||Relative elongation at tension,%||Hardness of Brinell, HB|
|1st group||2nd group||1st group||2nd group||1st group||2nd group|
