High grade materials can be selected over ordinary carbon steel or stainless steel grades for many reasons. But even thesse special materials, or even better particularly special materials must be handled with care. Improper use or handling can totally destroy their improved resistance and even make them weaker and more vulnerable than the common materials.
Bronswerk Heat Transfer is specialized in the application of high grade materials in Air-Cooled Coolers and Shell & Tube Heat Exchangers.
The application of High Grade Materials in your Air-Cooled Coolers or Shell & Tube Heat Exchangers can make them withstand more corrosive attack, guide higher flow, resist more erosion, handle higher pressure and extreme high and low temperatures. Often process industry requires these improved characteristics on their process equipment. While cladding is often applied in vessels and large Shell & Tube Heat Exchangers, in Air Cooled Coolers or small Heat Exchangers the only solution is the use of special materials as main construction material.
By using the right high grade materials you make your Air-Cooled Cooler or Heat Exchanger resist extreme circumstances over a longer period of time, making the higher investment worth.
The use of special materials applied in the appropriate circumstances can lower inspection intensity and so you reduce overall maintenance expenses.
Extended lifetime, less maintenance and spare part interchange and less troubleshooting increase the total uptime of your equipment and reduce the total operating cost.
Air-Cooled Heat Exchangers have to deal with several circumstances. Some of them are extreme, which can have an adverse effect on quality and service life, like corrosion and deformation.
From design to manufacturing, we specialize in the production and welding of high grade materials for high-end Air-Cooled Coolers.
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.
