Laser Welded Pillow Plates
Advantages with Laserwelded Pillow Plate
What are the advantages with Pillow Plates?
Laserwelded Pillow Plate is used in the following material thickness combination
|30 Bar steam and liquid||2.0 mm sheet welded on a 8.0 mm to 16.0 mm sheet|
|10 Bar steam and liquid||1.5 mm sheet welded on a 4.0 mm to 16.0 mm sheet|
|6 Bar steam, 8 Bar liquid||1.2 mm sheet welded on a 8.0 mm to 10.0 mm sheet|
|4 Bar steam, 6 Bar liquid||1.0 mm sheet welded on a 3.0 mm to 10.0 mm sheet|
|4 Bar water||0.8 mm sheet welded on a 2.0 mm to 6.0 mm sheet|
There are two different type of Pillow Plate possibilities, Single Embossed and Double Embossed.
Single Embossed is used for:
Double Embossed is used for:
Three Steps to Achieve a Pillow Plate
Step 1 - Laser Welding
Laser Welding is done in the flat position by a process of welding a top sheet to a bottom sheet.
This process is accomplished with no alteration to the product side of the bottom sheet such as pocking, pitting, or discoloration.
Step 2 - Forming
The laser welded panels are then formed into shells and heads.
There are no additional requirements for forming laser welded jacketed materials. Heads can be formed as dished or coned shapes.
Step 3 - Nozzle installation and inflation
After shell fabrication, nozzle installation and inflation can take place.
There are two methods that can be used:
- Inflate jacket with quill and install the nozzles after (utilizing same methods for nozzle installation as performed jackets).
- Install and inflate through nozzles.
The inflation process is very simple and each design will be given a proper inflation pressure and pillow height. Most design are inflate in a range of 20 to 60 bar.
Laser Channel Plate
The Laserwelded alternative to the half-pipe construction.
With the flexibility of CNC laser welding it is possible to weld any shape and design
