For the wax oil pipeline with DN300, how many heat tracing pipes are required?
The number of heat tracing wires varies depending on the minimum temperature that needs to be maintained; for conventional paraffin oil, we design two DN20 heat tracing wires
Generally, there are two heat tracing pipes, one on each side of the pipeline. This issue should not be determined by the manufacturing process; rather, it should be clearly specified in the construction drawings provided by the design institute during the design phase. My friend, this is a matter of responsibility.
On our end, the design office is absolutely infuriating – they only provided heat tracing for those areas that needed it; nothing else was supplied, not even the drawings for the heat tracing installation. So we decided to use two tubes based on our experience
What is the minimum maintenance temperature for wax oil heating? With your steam properties, the type of companion pipe you choose, and information on insulation, it’s possible to carry out the calculations.
