Laser Welded Pillow Plates

Advantages with Laserwelded Pillow Plate

What are the advantages with Pillow Plates?

Products advantages

  • Better performance
  • Better quality
  • Extended life

Manufacturing advantages

  • Increased productivity
  • Reduced fabrication

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:

  • Tank Jackets
  • High Pressure Bottoms
  • Conical Bottoms
  • Clamp on Plates

Double Embossed is used for:

  • Falling Film Chillers
  • Plate Bank Assemblies
  • Industrial Coolers
  • Ice Banks

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:

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

Product Advantages

  • Better performance
  • Welding possibility any shape and design
  • 100% surface quality on the vessel produce side
  • Controlled heat transfer

Manufacturing Advantages

  • Reduced fabrication costs
  • Less labor costs
