Design of the instrument heating system

As long as the piping team is willing, they can also handle electric heat tracing. A sheep can be herded, and a flock of sheep can also be herded.

The heat tracing for instruments installed on pipelines is designed by the pipeline engineering team, while the heat tracing for instruments not installed on pipelines is designed by the instrumentation engineering team. Most instrument heating is carried out using steam or hot water; for remote areas or those without access to steam or hot water, electric heating can be used.

This is the approach used in the design of chemical process instruments; other industries may not follow this method, so don’t lead people astray.

Electric heat tracing is suitable not only for various applications where steam heat tracing is used, but it can also solve problems that are difficult to address with steam heat tracing, such as heating long-distance pipelines, heating in confined spaces, heating equipment with irregular shapes (such as valves), as well as heating pipelines and instruments in areas where there is no steam source or in remote locations.

That’s indeed how the work is divided in chemical engineering design institutes, but in recent years there have been projects where everything was handled by the piping design team; this has been the case for several projects since PDMS was used for creating piping diagrams.

As long as the pipeline is not particularly long, it is usually handled by the piping specialists, and construction can be carried out according to the standard drawings. When the pipeline for a single instrument is very long, the instrumentation team needs to consider whether heat tracing is necessary and how to implement it. In terms of the sequence of project execution, heating long instrument pipes is also a hassle. Unless the general contractor designs it themselves, when the subcontractor is responsible for designing and estimating the total amount of heat tracing material, the instrumentation team has often not yet completed the detailed design. Estimating without ISO diagrams can lead to inaccuracies and result in business changes.

Hehe. . . In hazardous explosion-proof areas, I doubt anyone would dare to use electric heating. Although steam tracing is inefficient, consumes a lot of energy, and is difficult to implement, it is safe and does not cause explosions or fires. Therefore, designers naturally prefer to use steam tracing. As for the effectiveness of the tracing and the energy consumption issues, those are matters for the users; the designers don’t bother with them. In short, I have designed the tracing system for you – it’s up to you to decide how to use it. As for who will design the instrument heating wire, hehe. . I guess no one wants to do the design – it’s not a very heavy workload but it takes a lot of time. And whoever designs it is responsible for it, with no payment in return. Who in their right mind would want to take on such a task? As a result, there are very few estimates for the process design, and the instrumentation design relies on previous drawings provided by the procurement department; hence, the performance of the instrumentation heating systems in actual use is poor. To be honest, many of these designs are terrible.

They don’t care about electric heat tracing; they don’t pay attention to anything that’s energized

I’ve learned something – indeed, many things are due to calculation

Can pipes be designed with automatic control, but not electric heating? Let them do it.
