Regarding the selection of materials
Thread Content
A rich liquid buffer tank, with an operating medium that consists of H2S along with a small amount of dry gas or liquefied gas accounting for 15%, along with an aqueous solution of N-methyldiethanolamine. What material should be chosen? Can ordinary Q245R be used? Also, in what situations are seamless steel pipes used, and in what situations are forgings used? I’m a beginner; I hope everyone can help me a lot! Thank you!
The choice of material must be determined based on the temperature and pressure of the container, as well as other conditions! I wonder if the original poster is aware of the relevant operating conditions?
Design pressure: 1.75 MPa, design temperature: 85 degrees. If the opening is larger than 80, reinforcement is required; but when the opening is smaller than 80, what pressure level necessitates the use of thick-walled pipes for reinforcement?
If the pressure exceeds 2.5 MPa, it is necessary to determine whether a reinforcement ring is required; if it exceeds 4.0 MPa, thick-walled pipes are needed for reinforcement
Thank you for xht2040533’s answer!
The choice of material should be based on the properties of the medium, operating temperature, and operating pressure. When the working pressure is high or the medium is moderately hazardous, flammable, and explosive, seamless steel pipes should be used. However, seamless steel pipes are generally used when manufacturing containers. Strengthening calculations are required when the opening diameter is greater than 100 mm.
Our company uses 16MnR(R+HIC), not the ordinary 16MnR.
What are the performance differences between 16MnR(R+HIC) and regular 16MnR?
