Solving U-Tube (Hairpin) Exchanger Cleaning Challenges
From clearing blocked hairpins on a titanium heat exchanger for petrochemical plants in Saudi Arabia to polishing the metal on the hairpins of an unusual, aluminium tubed, furfural exchanger at a UK based BP refinery plant Tube Tech’s operatives are renowned as hairpin experts.
One of the most popular and widely employed heat exchanger configurations in the industry is the straight or U-tube hairpin shell and tube exchanger. With hundreds to tens of thousands of small-bore tubes bundled together in a square or triangular pitch configuration, the extent of scaling can involve major cleaning work to return the exchanger to anything near its commissioned performance. If the outside of the bundle is heavily scaled as well, the cleaning challenge rises by an order of magnitude.
Anyone involved in the maintenance of a site which involves a U-bend or hairpin exchanger will acknowledge that traditional cleaning techniques struggle to clean the hidden areas of these exchangers without immense mechanical intervention.
As the gurus of invention in the industrial cleaning field, Tube Tech has spent the past twenty years successfully creating better and faster ways to improve on traditional cleaning methods. Cleaning hairpin bends back to bare metal was a challenge the company met some time ago and has since perfected its technique within different industrial settings across the world.
Using a variety of unique cleaning systems including the miniature, high speed, rotating darTT and the intelligen metal Softdrill lance, Tube Tech can simultaneously clean and then video probe inspect hairpin shell and tube exchangers anywhere in the world. Please review the following case studies which demonstrate Tube Tech’s hairpin exchanger cleaning expertise.
Tube Tech is believed to be the only contractor to offer a full in house 3D animation and virtual reality mock up service of a client’s application to clearly demonstrate in real time and in a virtual world the effectiveness of their cleaning systems to clients.
