Application issues of heat-traced steam traps
Thread Content
An entire heat tracing pipeline is divided into a steam line and a condensate line by a trap, but the function of this trap is to prevent air from passing through while allowing water to flow. In the winters in the north, where temperatures drop below minus 20 degrees Celsius, steam is prevented from passing through, and it takes some time for the steam to condense into water; as a result, the condensate cannot flow freely, which often leads to freezing of the heat tracing system. By loosening the trap slightly so that steam can reach the condensate line, the problem of freezing is indeed resolved, but water hammer occurs frequently. How should this situation be dealt with? Is a trap not suitable for use in the northern regions?
The pipeline downstream of the steam trap is set to MIN and feeds into the main pipe. The pipeline should have a slope leading downward toward the main pipe, rather than bending upward into it. Reduced condensate horizontal piping
