HAL delivers biggest ever cryogenic propellant tank to ISRO

Hindustan Aeronautics Limited on Monday said it has delivered biggest cryogenic propellant tank (C32 LH2) ever fabricated by company to ISRO, much ahead of contractual schedule.

C32-LH2 tank is a developmental cryogenic propellant tank of aluminium alloy designed for improving payload capability of GSLV MK-III launching vehicle, HAL said in a release.

According to HAL, four-meter diametric tank is of eight-meter length to load 5,755 Kg propellant in 89 cubic meter volume.

total length of weld carried out in tank was 115 meters at different sts to quality requirement of 100 percent tests on radiography, Die penetrant check, and Leak proof, it said.
