  Digester Gas Piping Replacement

  From Existing Carbon Steel to a Complete Stainless Steel SystemRMIF was contracted to prefabricate, demolish, and replace an existing carbon steel digester gas piping system with new stainless steel piping. The project required careful planning from the fabrication shop through final field installation, with work taking place in an active industrial environment where hydrogen sulfide (H₂S) exposure was a critical safety concern. The project began with shop fabrication of the new stainless steel piping, allowing much of the system to be prepared before field work began. Once on site, the existing carbon steel piping was carefully removed and the new stainless system was fitted, welded, and installed. Working Around H₂S Hazards Digester gas can contain hazardous concentrations of hydrogen sulfide, making atmospheric safety a major part of the project. Work was performed under the facility’s required safety procedures, including H₂S awareness, atmospheric monitoring, and supplied fresh-air respiratory protection where required. These controls allowed our crew to safely perform demolition, fit-up, welding, and installation in areas where hazardous gas exposure had to be carefully managed. Shop Fabrication to Field Installation RMIF handled the piping scope from beginning to end: Stainless steel pipe and spool fabrication Existing carbon steel piping demolition Field fit-up and modifications Stainless steel welding Installation of the new piping system Coordination with existing equipment and piping Required site-specific safety procedures and training The completed project replaced the aging carbon steel system with a new stainless steel digester gas piping system, demonstrating RMIF’s ability to manage demanding industrial piping projects from initial shop fabrication through demolition and final field installation. Built in the shop. Installed in the field. Completed with safety and quality at the forefront.

  Heat Exchanger Replacement & Process Piping Upgrade

  Processing FacilityRMIF was brought in to replace an existing heat exchanger and rework the surrounding process piping at a processing facility. The existing configuration was inefficient and required modifications to improve the operation and flexibility of the system. Heat Exchanger Replacement The project began with removal of the existing heat exchanger and preparation of the system for the replacement unit. Existing piping had to be evaluated and modified to properly integrate the new equipment into the plant’s process. Rather than simply replacing the exchanger and reconnecting the existing piping, the system was reconfigured and repiped to provide a more functional installation. New Steam Line & Bypass As part of the upgrade, RMIF installed a new steam line and bypass piping arrangement around the heat exchanger. The additional piping provided the facility with greater flexibility in how the system could be operated and allowed the new exchanger to be properly incorporated into the existing process. The work required careful field layout, fit-up, welding, and integration with existing plant piping and equipment. Complete Field Modification RMIF's scope included: Existing heat exchanger removal and replacement Process piping modifications New piping fabrication and fit-up New steam line installation Heat exchanger bypass installation Tie-ins to existing plant piping Field welding and installation Final system modifications and completion This project demonstrates RMIF's ability to take an existing industrial process that needs improvement and develop the field-fabricated piping modifications necessary to make the new equipment work within the existing facility. From equipment replacement to process piping modifications, RMIF provides practical field solutions for industrial plant upgrades.
