【 yuling share 】 many aspects consider the heating tube design rationality!

Yesterday, we met a customer who asked us about the single-head heating tube in the electric heat pipe series. The specific requirements of the customer are as follows: 220V/1200W, pipe diameter: 16mm, length: 560mm, in which the heating zone is 520mm, single-head outlet line, working temperature: 800℃.

For such a problem, our first reaction is whether the diameter and length of the heating tube match the power.According to our analysis, it matches.However, the customer has a requirement of operating temperature of 800℃, we obviously reflect the choice of heating tube material, we must use SUS310S material, this material can withstand high temperature, the actual temperature resistance value can reach more than 900℃.This thought our direct according to customer requirements, choose SUS310S material can be.But think again, the parameters provided by the customer are contradictory to the work environment.In the working environment, the heating tube will never reach 800℃ due to its fixed surface load, so I put forward the design error to the customer and asked whether the heating tube purchased before could not reach 800℃ in any way.Finally, the customer replied that there was such a problem before, as heating could only reach 600℃ or so, so they thought it was the problem of heating tube and found another manufacturer.

Through such a case, in fact, when we design the heating tube, there will be such a misunderstanding, the temperature of the working environment and the surface temperature of the heating tube is related.When selecting materials, we should consider the temperature of the working environment as well as the surface temperature of the heating tube.In the above case, through our analysis to the customer, the customer finds out the crux and redesigns.This warned us yancheng feiyu alloy electrical appliances co., LTD. Sales and technology, many aspects of the heating tube design rationality.
