Do 20% ammonia pipelines need insulation?
Thread Content
As the title suggests, does a pipeline carrying 20% ammonia need insulation?
In Shandong region, winter temperature is -18 degrees
It’s used for denitration, right? There are no specific requirements for it; as long as it doesn’t freeze, that’s sufficient.
It is used to prevent stockouts; is it possible for pipes at minus 17-18 degrees to freeze?

It depends on where it will be used and what the local minimum temperature is
