What is the maximum winding distance for heat tracing copper tubes?
Thread Content
Is there any requirement or standard for the maximum winding distance of heat-tracing copper tubes? In our work, we usually use DN15 insulated copper tubes. However, when these tubes are used over an infinite length, it turns out that steam at 0.6 MPa cannot flow through them in the later stages – the pressure loss in the pipes is too high, or there is excessive heat loss, causing the steam to liquefy. As a result, the desired heating effect cannot be achieved at the downstream end. I would like to ask the experts: is there any requirement regarding the distance between such insulated tubes?
This is a matter of process design and calculation; standards can’t specify everything – at most they can provide an algorithm. Here are some discussions on steam heating and hot water heating: https://bbs.hcbbs.com/thread-1584284-1-1.html
