Bronswerk Heat Transfer has a long track record in the use of special materials in the Air-Cooled Coolers and Heat Exchangers they design and manufacture. We know all tips and tricks when it comes to working with these kind of materials. Especially welding requires special care due to the nature of these materials.
The process starts with a good and well thought (thermal) design. We optimize the (mechanical) design so that the number of welds and weld thickness and heat input is minimized. The less welds the better. Headers can be machined from a forged block of material instead of welding plates to form a square box or complex forgings can be manufactured in close cooperation with our trusted and distinguished partners.
Any remaining weld is handled with great care. We can rely on hundreds of welding procedure specifications made for a wide range of high grade materials, like (super) duplex, alloy 625, 800, 825, nickel and even titanium for various welding processes. We have these welding procedure specifications and welders certified according ISO 15614, ASME IX or HP5/3. We continue to extend this range if needed for any project. We understand that the use of the right shielding gas, filler metal and heat input all contribute to a high quality weld.
We can extensively test weld coupons, mockups and production welds to secure the quality is maintained during the production process.
This all to get a high quality product, with optimal corrosive, erosion, high pressure and extreme temperatures absorption properties.
