GOST 24301−93 refers to pipes of circular cross-section, which are made of cast bronze alloys of certain grades. It is established that the recommended dimensions of the outer diameter and the thickness of the wall of the rolled products should correspond to the following values: by diameter — from 40 to 200 mm, by 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 on individual orders. The company Evek GmbH offers a bronze pipe. Price from the manufacturer. The supplier provides prompt delivery of products to any address. The supply of pipes is carried out in a diverse assortment
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 are also established in the same limits for the ovality of the pipe. The specified limiting deviations are established for two groups of production. For the first group, the ovality tolerance, depending on the diameter, is from +0.6 and -0.1 to +1.2 and -0.4 mm. For the second group, from +1.0 and -0.9 to ± 2.0 mm, respectively.
Similarly, tolerances for wall thicknesses were established. In the first group, from +1.0 and -0.7 to +2.0 and -1.5 mm, in the second group from ± 1.0 to ± 2.0 mm.
