How are the elbows for the process pipelines in the CO2 stripping urea high-pressure system manufactured?
Thread Content
Please discuss: For the process piping elbows in your CO2 stripping urea high-pressure system, are they purchased as finished elbows or fabricated by bending straight pipes? If it is bent, is it hot bending or cold bending? Which production method is better?
They should all be finished elbow fittings; probably no factory dares to bend them on its own. With walls this thick, poor control can lead to serious problems.
They are all finished elbow fittings, manufactured by professional manufacturers, with the user able to provide the manufacturing parameters. Ordinary nitrogen fertilizer companies estimate that they do not have the capability to produce it.
It is difficult to meet the requirements for self-made elbows on pipes with large diameters and thick walls
All high-pressure elbows are purchased as finished products, with Snam and Stamicarbon each having their own standards
