Design of hydrogen-containing waste gas pipelines
Thread Content
Our company’s waste gas contains 1% hydrogen, as well as sulfuric acid mist and water vapor. We intend to use non-metallic pipes for this purpose, but the GB 4962-2008 Safety Technical Regulations for the Use of Hydrogen require the use of metallic pipes. Metal pipes are not resistant to corrosion; therefore we want to use non-metallic pipes. However, we are concerned about static electricity, so we wish to control the wind speed within the pipes. We are not sure which standard should be used for design purposes GB 50177_2005 Code for Design of Hydrogen Stations specifies flow rates for carbon steel and stainless steel pipes, but it seems to have limited practical value. I would appreciate it if professionals or colleagues could share their experience; thank you
Carbon steel pipes with linings and alloy steel pipes are both optional.
