Depending on the materials being welded, brittleness, cracking, porosity and residual stress are all factors equipment manufacturers have to contend with, unless they apply the right pre-heating and right post weld heat treatment (PWHT).
Getting this right greatly helps enhance equipment longevity and thereby avoid unplanned & unsafe shutdowns.
Reliable Cooperheat products
As Stork Cooperheat, we supply a range of innovative and versatile heat treatment solutions specifically designed with the needs of the operator and industry in mind.
Our products are recognized around the world for their quality, durability, reliability and the highest standards of safety. Our sales engineers are ready to listen to your needs and recommend the optimal solution for you.
The full range
Cooperheat was the company which introduced heat resistive ceramic pads to the industry in 1958 and has continued to innovate forward. Apart from the wide array of pads, they manufacture power transfer units (incl. the compact, quick intervention K9 model), programmers, controllers, recorders, thermocouples, and insulation blankets. Apart from state-of-the-art hardware, Cooper8 software allows remote monitoring of multiple heat treatments.
For preheating and expansion
When rapid heating is required, then induction can be the best option for you. Typically, this is the case during pre-heating, but it can also be applied to rapidly expand objects.
Examples of the latter include loosening seized nuts, removing old paint layers on metal surfaces, and dewaxing of pipeline segments.
High velocity burners
When you need to heat a piece of equipment from the inside, then high velocity fired burners could be the solution. Cooperheat was one of the pioneers of this technique, where rapidly recirculating gases break down layers of still air and increase the heat transferred by convection. Shorter heat-up times and improved temperature uniformity are the result.
Versatile & robust
Building on over 50 years of experience, Cooperheat can build the furnace that is right for your pieces of equipment. Bogie hearth, top hat, split roller cover, split top hat, guillotine door, … we have designs ready to go or be modified to suite your needs.
Cooperheat's designs are characterized by low heat-loss, achieving impressive energy savings. Apart from the hardware, you receive Cooper8 software to control the furnace heat and CCTV cameras can be installed if required.
Optimal equipment design
Extremely large / temporary furnaces can be designed if required. One example was a 70 meter long x 9m x 9m furnace to PWHT six bullet vessels. Twelve high velocity oil burners were installed, achieving +/- 7ºC at soak temperature.
This solution could be just what you need to give you optimal design freedom for your equipment, while still being able to heat treat it.
Temperature Control Software
Close temperature uniformity can be achieved using Cooper8, Cooperheat’s advanced programmable temperature control systems with multi-zone controls.
This software allows you to remotely control multiple heat treatments from one location (which can also be shared live with an expert, hundreds of kilometres away). It is key to note that Cooper8 can be applied, irrespective of the brand of the heat transfer units used.
