The three specifications related to the construction acceptance of metal pipes are confusing.
Thread Content
Having been troubled for so long, I had no choice but to come to Haichuan. Code for Construction and Quality Acceptance of Industrial Non-ferrous Metal Piping Projects GBT51132-2015, Code for Construction of Industrial Metal Piping Projects GB50235-2010, Code for Quality Acceptance of Construction of Industrial Metal Piping Projects GB_50184-2011. A large part of the content in these three items overlaps; why create so much of it? What is the meaning of existence? Why aren’t such important aspects as rust removal, corrosion prevention, and insulation mentioned? Please ask an expert to clarify this.
Tell them one by one. Starting with GB50184-2011 and GB50235-2010, their general provisions clearly state that these two standards are to be used in conjunction, so it is normal for there to be overlapping content between them. As for GBT51132-2015, being a standard specific to non-ferrous metals, the general principles for the construction and acceptance of metal pipelines remain unchanged; there are only differences in the details, which is why one might perceive overlap and repetition in the content. As for why so many are needed and what their purpose is, firstly, there are specific standards in place, which makes the construction inspection process easier and more targeted. Second, there’s no need to create so many regulations – what will the bosses of state-owned enterprises eat? You can take a look at the organizations that serve as editors-in-chief for these standards; they are not part of the same system, so naturally each of us writes our own work. Regarding tasks such as rust removal, corrosion prevention, and insulation, specialized standards have been established precisely because they are important. Moreover, the units specified in the above three standards are indeed not those specialized in rust removal, corrosion protection, and insulation.
