Shaped bimetal bimetallic tube sheet

May 08, 2023

The shape specific bimetal tube plate is called Shaped bimetal bimetallic tube sheet. Such as bimetal dish shape, basin shape, head shape, super semicircle and tapered tube sheet. The shape of these tube sheets can be determined according to the production process. Some of them can also drill holes in them and connect with the pipe to form a tube-sheet system for making heat exchangers and other equipment.

In chemical engineering and pressure vessels, Shaped bimetal bimetallic tube sheet is more reasonable than planar bimetal Tube sheet in terms of structure and technology, so it is used more and more widely.

adopts full-scale explosive welding technology, which not only welds the flat part of the bottom of the tube sheet, but also welds the fillet and straight edge positions. The fully composite tubesheet naturally is superior to the locally composite tubesheet. Because the cladding is integrated, the effect is better than that of local composite and bushing.

Chinalco adopts the following explosive processing technology for all-round composite tube sheets of dish, basin and hemisphere shape:


1. explosive forming + explosive welding

2. explosive forming explosive welding

3. explosive welding + explosive forming

4. explosive welding - explosive forming
