"Master Yu, is there a better solution for the "low, old, bad" phenomenon encountered in the flange assembly process? Do you think this welding spot affects the appearance of the weld, and the welding is not strong, there is still safety Hidden danger
It turns out that in the installation and construction of the site, when the flange connection with large pipe diameter is encountered, in order to maintain its stability, the conventional construction method is to spot weld the steel plate to the base material to fix the pipes on both sides for support; while spot welding The result is that there will be many solder joints inside and outside the base metal, which will have to be polished repeatedly in the later stage
The speaker is unintentional, the listener is intentional
It's easy to say, but it is not easy to ensure such a strict quality of pairing in actual operation
This flange counterpart has a cool appearance: it is supported by two small steel plates, and there are mini-tracks on both sides of the steel plates
"Master Yu, this portable flange pairing device is good.
At present, they have applied this invention to the station yard and valve chamber pipeline system of the first phase of the Mengxi Coal-to-Natural Gas Export Pipeline.
