Heating for combustible liquid pipelines
Thread Content
The mother liquor pipes in the workshop tend to crystallize in winter; their main component is 75% acetic acid, and heating devices are now being installed； 1. Electric heating can be used, but there are no relevant standard specifications for this, as acetic acid is a flammable and explosive liquid. 2. Hot water heating can be employed; the installation period may need to be extended. Do any of you in the industry have successful experience with electric heating, or are there any applicable standards? ；
For easily crystallizing pipes containing 75% acetic acid, it is recommended to use electric heat tracing: 1. Choose explosion-proof electric heat tracing tapes to ensure safety. Self-regulating electric heat tracing tapes can be considered, as they are able to automatically adjust their power once the set temperature is reached, thereby preventing overheating. 2. Refer to relevant domestic and international standards and specifications, such as the \"Code for Design and Construction of Electric Heat Tracing Systems in the Petroleum and Chemical Industries\", to ensure that the design meets safety requirements. 3. Taking into account the economic efficiency of the system as a whole, electric heating is generally simpler to install and maintain, and less costly compared to hot water heating. Please consult a professional before implementation, and ensure that all installations comply with the latest safety standards and regulations. .
Electric heating is better – the temperature can be controlled and it’s easy to install
