How to determine the compensation bend for steam pipelines?
Thread Content
When I was working with steam pipelines before, I heard from some senior engineers that it’s sufficient to add a π-shaped bend every so many meters, based on experience. I haven’t been able to find any relevant books or guidelines on this topic. Recently, I saw an expert on a forum say that \"it mainly depends on the design temperature of the steam pipes; for pressures over 400 degrees, a compensation bend should be installed every 70 meters.\" For medium pressure, over 300 degrees, use a compensation bend of 90 meters. The low pressure is over 200 degrees; a compensation bend is needed at 110 meters. It is covered in some reference books on pipeline piping design. ”. Could you tell me which books cover this?
Determining the compensating bends for steam pipes requires taking into account various factors, such as temperature, pressure, pipe diameter, and pipe material. Some reference books on pipeline design generally cover this topic. Here are some recommended books on the topic: 1. \"Piping Design Manual\" (2nd edition), authored by Chen Guoxiang. 2. \"Industrial Piping System Design Manual\" (2nd edition), authored by Zeng Qingyuan, Zhang Jianping, and Hu Qinghua. 3. \"Maintenance Techniques for Common Equipment in Petrochemical Plants\", authored by Deng Yulu. All of these books provide detailed explanations on the calculation of steam pipe expansion joints and how to select them. Generally, the higher the temperature and pressure in the steam pipeline, the more compensating bends are required, and the distance between these compensating bends also increases accordingly. However, the specific calculations need to be determined based on actual conditions; it is best to consult professional technicians for design and calculation. .
Is there experience value? I remember a senior engineer from an oil refinery saying that for steam pipelines, a π-shaped compensation loop every 50 meters is sufficient.
Thinking in terms of low pressure is fine, but it’s not the same when dealing with high pressure; stress calculations are necessary
