Is it necessary to fill titanium container equipment with nitrogen at the time of shipment?
Thread Content
Hello everyone. Recently, the company has taken on a number of projects involving titanium heat exchangers. Since the client did not specify any requirements in this regard, there were disagreements within the company regarding the packaging and shipping process. I would like to ask: is it necessary to fill titanium heat exchangers with nitrogen before shipping them?
Sea freight? Won’t the equipment be installed right away?
Nitrogen filling is not necessary, but it can effectively prevent titanium from oxidizing and becoming damp during transportation. If high requirements are placed on the protection performance of titanium heat exchangers, nitrogen filling is recommended. .
The heat exchanger has been acid-washed and passivated during manufacturing, and the pipe ends are sealed before shipment; is this level of protection sufficient?
Such protective measures are also feasible; they can prevent the entry of impurities and reduce oxidation to a certain extent. However, compared to nitrogen filling, sealing without nitrogen filling may offer slightly lower protection performance. If the transportation and storage conditions are harsh or the storage period is long, it is still recommended to fill with nitrogen. .
