In the chemical processing sector, corrugated packing is a vital component for separation processes, and compliance with international standards is essential for ensuring its reliability, safety, and performance. These standards set benchmarks for material quality, structural design, and operational efficiency, making them non-negotiable for manufacturers and end-users aiming to meet industry requirements.

Key International Standards and Their Significance in Corrugated Packing
International standards like ISO 9001 (quality management), ASME B31 (pressure equipment safety), and TEMA (Tower Equipment Manufacturers Association) specifications govern corrugated packing production. These standards ensure that the packing meets strict criteria for corrosion resistance, temperature tolerance, and mechanical strength. For instance, metal corrugated packing, often crafted from 316L stainless steel or titanium, complies with ASME B31.3 for high-pressure service, while plastic variants like PVDF or PTFE adhere to ISO 11116 for chemical resistance. Structurally, the corrugated design—typically with angles of 30°/60° or 125°/150°—maximizes specific surface area (up to 500 m²/m³) and minimizes pressure drop, enhancing mass transfer efficiency in distillation, absorption, and extraction columns. This design is widely applied in petrochemical refineries (for crude oil separation), pharmaceutical plants (for active ingredient purification), and environmental treatment facilities (for waste gas absorption).
FAQ:
Q1: Which key international standards does chemical industry corrugated packing comply with?
A1: ISO 9001 (quality), ASME B31 (pressure safety), and TEMA (tower equipment design) are primary standards, ensuring product reliability and operational safety.
Q2: How does material choice affect compliance with international standards for corrugated packing?
A2: Materials like 316L stainless steel or PVDF meet high-purity and corrosion resistance requirements, critical for compliance with standards in harsh chemical environments.
Q3: What metrics define if a corrugated packing meets international efficiency standards?
A3: Metrics include HTU (height equivalent to a theoretical plate) ≤0.5 m and F-factor (pressure drop) ≤0.15 Pa·(kg/m³)^0.5, ensuring optimal mass transfer efficiency.
