Laser Welded SS316L Heater Exchanger Pillow Plate 2x12m Rectangular

Description of pillow plate

The Pillow Plate also called heat exchanger plate, consists of two stainless steel sheets that are laser welded together by welding a custom circle weld pattern. The outside perimeter of the Pillow Plate is fully laser welded to create a pressure boundary. At the edges of the Pillow Plate, a contour is welded to create a pressure-tight part.

Competitive Advantages of Pillow plates / Dimple plates 

• Less chance of leaks due to high quality welding.
• Higher heat transfer coefficients at lower flow rates.
• High efficiency in energy transfer/ dimple patterns enable better flows resulting in high-energy efficiency.
• Pillow Plate is integrated in the structure, giving it extra strength.
• According to the application any design is possible. 

Advantage of pillow plate

1. Faster production with less material.

2. Very strong, reliable, constant high-quality welds.

3. Convenient for the welding of stainless steel, carbon steel, duplex, titanium and numerous other alloys.

4. Less deformation during welding, because of relatively low heat-input by the laser beam.

5. Inside of the tank is not affected, no rework needed,, even the protective film can stay on during welding.

6. Unlimited under-plate thickness, as the laser beam only penetrates from one side.

7. As any shape can be designed and welded, tailored solutions can be created.

8. Fully automated welding-process with low cost of labour and high-quality end product.
