According to the relevant requirements of GB50030 and GB16912, carbon steel pipes can be used when the oxygen pressure is less than 3.0 MPa, but the flow velocity must not exceed 15 m/s； Above 3.0 MPa, carbon steel cannot be used regardless of the flow rate. So the question arises: can oxygen pipelines with a pressure of over 3.0 MPa be considered as those with very low flow rates? Can carbon steel be used for oxygen storage tanks at 6.0 MPa? The oxygen cylinders used for welding have a pressure of up to 15 MPa and are made of carbon steel.
Oxygen storage tanks can be made of carbon steel.
For oxygen storage tanks, the key consideration is complete degreasing of the inner wall; if cleanliness is a concern, stainless steel should be chosen.
