Is there a classification system for pressure pipelines applicable to steel-lined pipes? Is the applicable pressure pipeline classification standard used? ?
It applies; as long as it is a pipeline, including non-metallic pipelines, it should fall under the classification of pressure pipelines. A pressure pipeline is defined as a pipeline, without specifically referring to metal pipelines. Therefore, any pipeline that meets the defined conditions should be applicable. However, the regulations state that non-metallic pipes shall be subject to other safety technical specifications.
Well, since the regulations state that non-metallic pipes should comply with other safety technical specifications. Does that mean non-metallic pipes are not classified as pressure pipes in this way, and thus this classification does not apply to them?
The definition of pressure pipelines is based on the new catalog; according to this definition, non-metallic materials are considered pressure pipelines. Non-metallic pipes as mentioned in the regulations are required to comply with other safety technical specifications; in my understanding, this means that in addition to meeting the requirements of the regulations, they must also satisfy certain other safety technical standards. The regulations do not state that non-metallic pipes are not applicable. It’s just my personal opinion; feel free to give your feedback!
It must have been established in accordance with pipeline safety standards; the others are mainly safety technical specifications – as long as they meet the requirements, that’s sufficient
