Installation Procedure

1. Ensure the pipe ends are clean, free of debris, and properly chamfered according to applicable welding procedures. 2. Align the pipe sections precisely using appropriate alignment tools and tack weld securely at multiple points. 3. Proceed with full welding in accordance with established industry codes (e.g., ASME B31.3) and qualified welding procedures, utilizing suitable filler materials for carbon steel. 4. Perform post-weld heat treatment (PWHT) if required by the service conditions or applicable codes. 5. Conduct thorough non-destructive examination (NDE) of all welds, followed by hydrostatic testing to verify system integrity.
