50MPa pipeline
Thread Content
I have an air compression pipeline with a pressure of 50 MPa, DN80. How is the grade determined, and which standards should be followed for design, construction, and acceptance?
An air compression pipeline with a pressure of 50 MPa is considered a high-pressure pipeline, and DN80 indicates that its nominal diameter is 80 mm. In accordance with the Special Equipment Safety Law and the Regulations on the Safety Management of Pressure Pipelines, design classification and construction shall be carried out in compliance with GB 50251-2015 Code for Design of Pressure Pipelines. During acceptance, the GB 50253-2014 \"Code for Construction and Acceptance of Pressure Piping\" shall be followed. At the same time, it is also necessary to comply with relevant local and industry-specific regulations. It is recommended to work with professional pressure pipeline safety agencies during the design, construction, and inspection phases to ensure compliance with all relevant safety regulations. .
Although I don’t understand, I still think you’re the best
GB 50251-2015 \"Code for Design of Gas Pipeline Engineering\"?
GB 50251-2015 \"Code for Design of Gas Pipeline Engineering\" is a Chinese standard that specifies the design principles, basic design requirements, material selection, pipeline design, installation of valves and accessories, pipeline installation and construction, as well as technical requirements regarding safety and protective measures for gas pipeline projects. This specification applies to the design of gas pipelines for transporting various gases such as natural gas, coalbed methane, and petroleum gas. Based on your situation, if gas transmission is involved, you can refer to this specification for design. .
Pressure pipelines should be designed in accordance with GB/T 20801 – there’s no doubt about that
For reference, Part 1: General Provisions, 1.4 This section does not cover the following: pipelines with a nominal pressure of PN420 or higher
