Methods such as radiographic testing (X-ray) or ultrasonic testing are used to verify weld integrity, especially on critical high-pressure lines.

cause excessive pressure drops. This increases compressor work, lowers system capacity, and raises energy costs.

Most local jurisdictions in the US, Canada, and Europe adopt IIAR 2 alongside ASME B31.5 (Refrigeration Piping). If you are a contractor, engineer, or plant owner, failure to comply with the latest edition of IIAR 2 is a violation of occupational safety (OSHA General Duty Clause). Having the PDF allows you to pull up specific clauses during an audit or incident investigation.

Low-temperature carbon steel (A333 Gr 6) for loops < -20°F. Prevents brittle metal fracturing. Butt-welding or socket-welding; minimal threading. Eliminates high-risk leak paths. Oil Return

The small internal passages found in expansion valves and other control valves are particularly sensitive to fouling and plugging with relatively small amounts of dirt and debris. Particular care must be taken during installation to ensure cleanliness and minimize the introduction of weld scale, dust, and other types of debris.
