The gas pipeline of the heating furnace uses natural gas; what material is suitable for it?
Thread Content
The total sulfur content in natural gas should be ≤200 mg/m3, and hydrogen sulfide content should be ≤20 mg/m3. Which material is more suitable for gas pipelines: 304 or 20#?
From an economic perspective, 20# is more suitable for gas pipelines; however, \"the material for gas pipelines supplying fuel to continuously burning lamps should be stainless steel to prevent the formation of iron debris due to corrosion\" (source: \"Guidelines on the Installation of Interlock Protection Systems for Tubular Heaters in Sinopec’s Refining Units\").
Thank you for the reply; I happened to want to know as well.
Could you send me the guidance guidelines for setting up the interlock protection system for tubular heaters in Sinopec’s refining units?
