Question about piping issues
Thread Content
For the stainless steel seamless pipes used in high-pressure oxygen pipeline installation, should hot-rolled pipes or cold-rolled pipes be chosen?
What is the difference between hot-rolled steel pipes and cold-rolled steel pipes?
Hot rolling and cold rolling mainly refer to the production processes, and there are definitely differences between them. In terms of performance, hot-rolled pipes have large deviations, while cold-rolled pipes offer high precision. In terms of economic efficiency, hot rolling has high efficiency and low costs, making it suitable for mass production, while cold rolling has low efficiency and high costs, allowing for small-scale production.
The vast majority of stainless steel seamless tubes are produced by cold rolling or cold drawing. As for the differences in usage you mentioned, it mainly depends on the pipeline standards you require. Whether it is hot-rolled or cold-drawn, as long as it meets the operational conditions and compliance standards, it can be used.
Am I answering his question about the difference between hot rolling and cold rolling? P
