Pressure pipelines involve all walks of life, and the basic requirements for them are "safety and use". In order to use safety, use must be safe. The use also involves economic issues, that is, low investment and long service life. Of course, this is related to many factors. Materials are the foundation of engineering. First of all, we must understand the special requirements of metal materials for pressure pipes. In addition to bearing loads, pressure pipelines also endure special tests due to working in different environments, temperatures and media.
