Langfields have unrivalled experience and expertise with the use of orbital welding on reformer pigtails. Having carried out numerous shutdowns across the globe we have been able to refine and improve the process and procedure so that a best possible weld profile is achieved.

Due to the quality of the weld profile we are able to achieve and the refinement of the process significant time and cost savings are made with longer times between shutdowns and improved speed and efficiency of shutdowns.
