a feature
The 20-1500MM thick tube sheet is subjected to one-time uniform expansion at full thickness.
Extend the intermediate tube plate or multi-tube plate heat exchanger at any depth.
Extend the internally threaded pipe or the seamed welded pipe.
After the expansion, the residual stress is low, and crevice corrosion is not easy to occur.
After the heat exchanger is expanded, the axial direction is not elongated and slightly contracted, which is beneficial to reduce running noise.
The inner hole of the pipe has a large error, and the diameter of the expansion head can be appropriately adjusted on the spot.
There is no oil pollution in the expansion joint, and the welding is not affected after the expansion.
It is very convenient to directly swell at the edge of the heat exchanger with the pipe box.
9, a single person can continuously expand, can expand 4 & mdash per minute; 8 tube heads.
10. The comprehensive economic benefits have been greatly improved.
