Hello everyone. Our company is currently working on a project that involves a pure steam distribution system. I want to know whether the pipes in this system fall under the category of pressure pipes Is it necessary to submit for approval? Operating condition: delivery pressure of 0.35 MPa; pipe diameter in accordance with ASME BPE standards; lengths of 60 m for DN100, 90 m for DN80 and DN65, and 130 m for DN50. Please help to answer it. Waiting online, urgently.
This place belongs to you. 1. The medium is steam. 2. The operating pressure is 0.3 MPa, which is greater than 0.1 MPa. 3. The pipe diameter is at least DN50 in all cases.
Pressure pipelines refer to tubular devices that use a certain pressure to transport gases or liquids. They are defined as those with a maximum operating pressure of 0.1 MPa (gauge pressure) or more, where the medium is a gas, liquefied gas, steam, or a liquid that is flammable, explosive, toxic, corrosive, and has a maximum operating temperature equal to or higher than its standard boiling point; furthermore, such pipelines have a nominal diameter of 50 mm or more. Except for pipes with a nominal diameter of less than 150 mm and a maximum operating pressure of less than 1.6 MPa (gauge pressure), as well as the pipes that form part of the equipment used for transporting non-toxic, non-flammable, and non-corrosive gases.
Are there any supplementary or additional regulations stating that structures with a length of less than 1000 meters do not need to be submitted for approval?
Pressure pipelines have nothing to do with length!
It falls under the category of pressure pipelines. 1. The medium, being steam, meets the requirements. 2. A pressure of more than 0.1 MPa meets the requirements. 3. A diameter of more than DN50 mm meets the requirements. It should be managed in accordance with the requirements for pressure pipelines
It has nothing to do with length; just declare it.
There are so many pipes in a chemical plant that it’s impossible to connect any of them over a distance of 1000 meters; it’s obvious that such a rule cannot exist.
Pressure pipelines are not related to length; whether they are subject to regulation depends on local requirements.
If it belongs to pressure pipelines, it depends on whether the local regulatory authorities are in charge of it
