Are there any requirements regarding the materials used for the liquid-contacting parts of LNG/LPG equipment in terms of design and production?
Thread Content
We plan to use the thermometer from the atmospheric pressure tank for LNG and LPG; what considerations are needed for this modification? Consultation is available for a fee. 1. What are the requirements for the material of the liquid-contacting part? What material should be used now instead of cast aluminum? What is the standard based on? 2. If there is wiring from intrinsically safe to flameproof areas, glue and plugs were used in the past; are LPG/LN permitted, and are there any new requirements? 3. What are the criteria for dividing LNG/LPG zones 0 and 1? Thank you
The minimum operating temperature of the thermometer material must meet the requirements; check JB4734 and GB18442 regarding the material and measurement range.
Hello, have you ever dealt with equipment before? I would like to ask whether there are no specific design standards for the material of the gauge, and whether it has to meet the requirements of the container. May I add you on WeChat?
