Post Weld Heat Treatment refers to the heating treatment applied to an area post welding – this aims to get the steel back to its prefabrication strength. The welding process places stress on the steel, often due to high carbon content. This forces manufacturers to apply certain treatment techniques quickly after the welding has taken place to ensure the maximum return of durability and strength. Even though welding has enabled many advances in manufacturing, it does unavoidably, cause damage. Can this process be completed on-site? We have the answer!
Gulf Coast Combustion and On-Site PWHT
If PWHT is not performed correctly, or not done at all, residual stresses can exceed a material’s limitations. What happens when design limitations have been exceeded?
Due to the nature of the industry that mostly uses PWHT – the petroleum and chemical processing industry – the designs are usually very large in stature. The manufacturing, welding, and PWHT need to happen at one site to ensure the safety of the product and the manufacturing site. Transportation of such large items can pose a dangerous hazard – one that can be avoided by mobilizing units to apply PWHT on site. Gulf Coast Combustion has successfully combined its industry expertise, leading engineers, and equipment to create mobilized teams that can assist manufacturers on site.
The techniques, control, and monitoring of the heat and cool-down phases are possible on site. This allows the client to also monitor the process from beginning to end – ensuring quality and goals are met. A time-lapse video of on-site PWHT can be viewed here. The on-site treatment lacks no quality in application or control – all safety and manufacturing codes are strictly adhered to. Using our industry-leading techniques on-site ensures a quick turnaround time – creating a smooth project timeline for our clients.
GCC customized thermal solutions, for a variety of industrial applications, reduce costs and assure quality control for our customers. By applying PWHT on-site, the cost is cut down drastically. The products do not need to be hauled to and fro – which can hike costs drastically for such large items. Employees are also not put in dangerous situations to move the items unnecessarily – they can be manufactured, welded, and treated in one area.
Gulf Coast Combustion has teams ready to mobilize across the US to assist with PWHT on-site, ensuring maximum client satisfaction and project success. We deliver time and time again by strictly adhering to safety standards – Think Safe Work Safe – and we proudly apply this to our daily operations. We use powerful equipment that will get the job done on time – to standard and specification. Our trained and expert technicians are industry leaders and will handle each project with care.
