Pillowplate laser welding
Generally 98% of the pillowplate material is stainless steel, 304L up to 254SMO.
Pillowplates can be designed with thin top plates for the applicable working pressure. For instance with 1.0 mm plate we can reach a burst pressure of 180 bar. With 2.5 mm we can design heat exchanger plates with burst pressures of 400 – 500 bars.
The working pressure global guideline:
- Water / glycol / thermal oil: 1 – 5 bar
- Refrigerant Freon – NH3: 19 bar (at 20oC)
- CO2 refrigerant: 120 bar
- Steam: 0.5 – < 30 bar
The maximum product size depends on the width of the laser welding machine. Products larger than 2000 x 2000 mm should be divided into a maximum machine width of 2000 mm. Thickness of the pillowplate, base plate + top plate can be 30 mm.
