In the low temperature environment, metal materials will produce cold brittleness at low temperature, that is, strength and hardness increase, plasticity and toughness decrease significantly, which will seriously affect the safety of the valve.
At the request of Russian customers, in order to test the low temperature resistance of Guangde tank valve products, a third party inspection organization was invited, and the products were tested at low temperature with the witness of engineers from Russian Classification Society.
In this low temperature test, Guangde chose a very harsh test environment. Specific test conditions are: temperature – 65 C, heat preservation for 6 hours.
The test was carried out in accordance with the requirements of the Russian Classification Society ND NO.2-09021-009-E.
