Spiral tube
Thread Content
Spiral pipes are used for steam transportation. Are there any pressure restrictions? If the pressure is too high to use a spiral pipe, what kind of pipe is suitable?
According to the "Pressure Pipeline Specification" GBT20801-2006, spiral pipes cannot be GC1 pipes, but steam belongs to GC2 pipes, so there should be no restrictions.
For steam pipes with too high pressure, spiral pipes cannot be used. Seamless pipes made of No. 20 steel or seamless pipes with a higher grade of material should be used.
