Pre-heating, post-heating and welding services
Electrical Pre-heating is provided by applying an electrical heat element on the outside body of casing and wellhead as per approved WPSs & PQRs based on API & ASME standards to ensure uniformly and steady distribution of heating for the base metal before& during welding to prevent cracking and maintain the mechanical prosperities for casing & flange material. Welding service is provided by approved WPSs & PQRs as per ASME standards with experienced 6gr welders, calibrated SMAW machines.
Post-heating is provided by applying an electrical heat element on the outside body of casing and wellhead as per approved WPSs & PQRs based on API & ASME standards for critical grades to prevent cracking and making stress relief by digitally controlling the heating, cooling rates and holding time.
