Preheating involves heating the base metal, either in its entirety or just the region surrounding the joint, to a specific desired temperature, called the preheat temperature, prior to welding.
Post Weld Heat Treatment (PWHT)
Post Weld Heat Treatment, or stress relief as it is sometimes known, is a method for reducing and redistributing the residual stresses in the material that have been introduced by welding.
Shrink fitting refers to pre-heating the metal components between 100°C and 350°C thereby causing them to expand and allow for the insertion or removal of another component.
Curing & Coating
Curing uses heat to initiate a chemical and molecular structural change in a polymeric material. These materials are applied to various products for sealing, protective coating, insulation and other uses.
Hot tapping strictly refers to the installation of connections to pipelines while they remain in service. This means that a pipe or tank can continue to be in operation whilst maintenance or modifications are carried out.
Our patented Bolt Heating System utilises specifically designed induction tools to thermally 'elongate' bolts in a fraction of the time of conventional methods.
Our Induction powered Coatings Remover provides a fast, clean method of removing paint and Intumescent coating from metal surfaces.
We have designed and manufactured a Patent Protected Rotational Heating Clamp to be used with our Rapid Heat 35kw Liquid Cooled Unit.
Rapid Heat Systems designs and constructs coils of various sizes on request. These can either be openable, shell-type coils; fastened
from the inside or from the outside.
