It’s no problem; stainless steel can be used in conjunction with carbon steel heating pipelines. For the pipelines that we use extensively, which are insulated with hot water jackets or steam jackets, the inner tube is made of 304 stainless steel, while the outer jacket is made of carbon steel. This setup does not lead to significant potential difference corrosion, and such pipelines have been in use for over a decade with good performance. The design was carried out by China Tianchen Company.
Upstairs, what you have there is a jacketed pipe, but the original poster was asking about heat tracing. Generally, heat tracing is applied closely around the main pipe, which can lead to carbon infiltration. It is recommended that the poster use electric heating; it’s simple, but it might be more expensive than steam heating.
It’s possible, but it is necessary to use a spacer in accordance with the specifications between the carbon steel heat pipe and the stainless steel tube to prevent carburization
It is acceptable to use carbon steel for the heat tracing wires of stainless steel pipelines; this is exactly what our company does. It is cost-effective and practical, with no need to consider other issues.
A combination of 304/20# can definitely be used. We have many years of experience in using this combination. Of course, the pipes must be properly rust-removed, and the heat tracing tubes must be welded using TIG welding to ensure quality. This combination is also the most economical option, facilitates maintenance, and allows for fast installation – it is highly recommended
There’s no problem at all. Most factories do this.
It is estimated that the poster is referring to using CS pipes as if they were copper pipes for heat tracing, and there is no problem with that; just make sure to provide proper isolation.
It is possible to use carbon steel pipes for heating stainless steel pipes, but an asbestos sheet should be placed at the contact surface. Special attention must also be paid to the wires used to tie the pipes together; if these wires are galvanized on the outside, they must also be properly insulated from the stainless steel pipes, usually by using an asbestos sheet.
Our company uses copper pipes, which are convenient for connecting and bending
If a carbon steel pipe is used for heating a stainless steel pipe along with a insulation layer, the heat transfer efficiency **decreases**. It can be heated using a jacket or electric heating. What would be the effect of using a stainless steel tube to provide heat tracing for another stainless steel tube? Is it possible to do this? ? ?
