Pipeline weld proportion detection
Thread Content
For example, water-sealed white phosphorus is transported using stainless steel pipes. Let’s discuss what the appropriate proportion of welded joints in pipelines should be
Selection must be made in accordance with the standards in the attachment
You’re completely ignoring the question and giving answers randomly. Negative review
The specific proportion of flaw detection can be referred to the relevant provisions in the \"GB 50184-2011 Code for Acceptance of Construction Quality of Industrial Metal Piping Projects\" and the \"GBT 20801-2006 Code for Pressure Piping – Industrial Piping\".
This post was last edited by Gong Gong Gong Gong on 2018-12-3 at 10:38. Isn’t white phosphorus a solid? How can it be transported through pipelines? If it is transported through pipes, does the “weld proportion” you mentioned refer to the proportion of welds that are inspected? If it’s on the second floor, the answer has already been given; if not, I also don’t know what this highly specialized term you mentioned, “weld ratio,” refers to.
I’m most afraid of getting a reply full of rules and text – just look at the question. My operating conditions are no longer within the scope of the specifications~
Being picky about details refers to the inspection grade and inspection ratio of pipeline welds. Then take a look at the question again: this powdered substance, when mixed with water and transported through pipes, is no longer a fluid, so applying these standards is no longer meaningful.
May I ask, does a liquid-solid mixture not belong to fluids? Where did this definition come from? As long as your pipes are industrial metal pipes, they fall within the scope of the requirements specified in the \"GB 50184-2011 Code for Acceptance of Construction Quality of Industrial Metal Pipe Projects\".
It is recommended to conduct 100% flaw detection, as any leaks could lead to spontaneous combustion! Safety is important! It is recommended to use flanges sparingly, as they are prone to leakage. As for the specific detection ratio, if there is a design, it will be determined according to that design.
White phosphorus is a white or pale yellow, semi-transparent solid that catches fire at around 40°C in humid air, and at a slightly higher temperature in dry air. Melting point 44.1°C. Moreover, white phosphorus is a toxic substance that must be transported under a water seal in stainless steel pipes; in accordance with the \"SH3501-2011 Standards for Construction and Acceptance of Steel Pipes for Toxic and Flammable Media in the Petrochemical Industry\", 100% radiographic RT inspection is recommended.
It’s not necessarily necessary to adhere to the standard; the standard specifies 20%, but for safety reasons, companies can use a higher standard of their own. If the pipeline isn’t very long, there’s no harm in using 100%
