Taking advantage of most advanced bolting equipment, PSA provides controlled loosening and tightening bolts from small jobs to large turnarounds. Disassembling, assembling and preloading verification of bolted joints are the services in this category. Realizing the importance of the bolting role in safety and proper operation of the joints, we pay special attention to critical elements of overall joint integrity, including flange surface quality, joint alignment, gasket selection, bolt preparation and uniform bolt loading using the most appropriate torquing/tensioning methods. PSA technicians and engineers always focus on the followings:

• Controlling all critical elements associated with bolted joint integrity
• Inspection of flanged joints in accordance to ANSI/API specifications
• Approval written procedures are used to bolt joints
• Assembling of the joints properly aligned using the appropriate gaskets
• Cleaning and lubricating of the bolts and nuts
• Bolts tightening using best practices to achieve uniform bolt loading
