Improved topside thermal insulationTrelleborg has launched Flexspacer, a product developed to effectively create an air gap between topside pipelines and thermal insulation, thereby avoiding the corrosion that can occur when using traditional insulation systems such as mineral wool. By stopping direct contact between the insulation material and the pipe, Flexspacer prevents any damage to the corrosion protection on the pipe, helping to guarantee thermal performance.
Historically engineers have made air gaps between the pipe and thermal insulation using an additional sheet of metal applied in a wave pattern. However, this method can cause undesirable side effects including corrosion of the metal sheet and injury to engineers during work due to its sharp edges. Compared to these traditional methods, Flexspacer provides quick and easy installation, without the need for hot work or special tools, in turn reducing downtime and improving safety.
Trelleborg has undertaken extensive testing on Flexspacer, and it has been qualified for use up to 150°C continuous service temperature, for more than 30 years.
