What proportion of the total welds do the pipe fixing joints account for?
Thread Content
Experts, what proportion of the total number of welds do pipe fixing joints account for? An analysis and statistics are conducted based on the general production and installation conditions at construction sites.
?I don’t understand what fixed joints and on-site welds mean Pre-fabricated weld joint?
The fixed end is welded on-site with the pipe remaining stationary; it is relative to the prefabricated pipe, which can be rotated for welding. The proportion of each component isn’t clear, as I have never worked on site.

If the design drawings are reliable, it seems that a value of over 60 can be achieved
Ideally, it is desirable to minimize the number of fixed openings, but this cannot be generalized as it depends on factors such as the shape of the pipes, site conditions, and lifting capabilities
This relates to the construction philosophy, as well as issues of efficiency and cost. Given the limited space on offshore platforms, the proportion of prefabricated components can reach over 75%; other modular design approaches can also enable this proportion to exceed 80%. It’s necessary to figure out how to plan this
Just make the markings and conduct the statistics based on the actual conditions. The prefabrication depth depends on the site conditions as well as the technical skills involved; obviously, the fewer fixed connections there are, the better, as it is more cost-effective in terms of both quality and expense
