The core of carbon steel pipe design is ensuring its pressure-bearing capacity under operating pressure. The pipe wall thickness needs to be calculated and determined based on the medium pressure, pipe diameter, operating temperature, and material strength. Commonly used formulas include design formulas from ASME or GB standards to ensure that the pipeline will not undergo plastic deformation or rupture during long-term operation, while also considering economy and material utilization.
The design of carbon steel pipes also requires consideration of connection methods and sealing performance. The selection of connection methods such as welding, flanges, and threads should be based on the pipeline's operating environment and maintenance requirements, while ensuring reliable sealing. The machining accuracy of the pipe ends, weld quality, and the selection of sealing gaskets are all important factors in ensuring that the pipeline system does not leak.
When designing carbon steel pipes, the properties of the medium and environmental conditions must be assessed. If necessary, anti-corrosion measures should be added or internal lining/coating treatments should be used to extend service life. At the same time, a safety factor is usually used in the design to consider unexpected overpressure, temperature fluctuations, and aging factors, ensuring that the pipeline system can still operate safely under extreme conditions.
