Overview
ISO 21172-1:2015/Amd 1:2018 is an amendment to the international standard governing the design and construction of welded steel pressure drums for gas transport, specifically for cylinders with capacities up to 1,000 litres. This amendment updates several normative references and technical requirements to enhance the safety, quality, and reliability of gas cylinders used worldwide. Developed by ISO Technical Committee ISO/TC 58, Subcommittee SC 3, the standard ensures compliance with global best practices in pressure vessel manufacturing, focusing on welded steel gas cylinders designed for transport purposes.
Key aspects include:
- Applicability to welded steel pressure drums up to 1,000 litres capacity
- Enhanced safety protocols for potentially corrosive environments
- Updated testing and inspection methods referencing cutting-edge standards
- Alignment with international manufacturing and quality assurance requirements
Key Topics
Design and Construction Requirements
- The amendment clarifies design considerations for welded steel drums to withstand pressure safely.
- Special attention is given to the use of dished ends convex to pressure, with warnings about corrosive service environments to prevent premature failures.
Normative Reference Updates
ISO 21172-1:2015/Amd 1:2018 revises critical normative references impacting testing and quality assessment procedures, including:
- ISO 148-1: Charpy pendulum impact test methods for metallic materials ensure material toughness.
- ISO 17636-1: Radiographic testing for weld inspections enhances detection of internal defects.
- ISO 11363-1: Specifications for taper threads in valve connections improve compatibility and safety.
- ISO 19232-3: Standards for radiographic image quality classes support precise non-destructive testing.
- ASTM A285/ASTM A285M-12: Carbon steel pressure vessel plate specifications for durability and strength.
- ISO 3452-1: Principles for penetrant testing in non-destructive evaluations.
- ISO 15614-1: Welding procedure tests for arc and gas welding of steels ensure reliable weld quality.
Safety and Maintenance Guidance
- A critical warning about the use of dished ends in corrosive service environments highlights the importance of selecting appropriate drum designs to avoid corrosion risks.
- Quality assurance procedures are aligned with updated standards to maintain integrity throughout the service life of gas cylinders.
Applications
ISO 21172-1:2015/Amd 1:2018 applies primarily to manufacturers, designers, and quality controllers responsible for welded steel gas cylinders used in:
- Industrial gas transport: Secure transport of inert, flammable, and toxic gases in capacities up to 1,000 litres.
- Medical gas supply: Ensuring compliance with safety standards for cylinders used in healthcare environments.
- Chemical and petrochemical sectors: Safe storage and delivery of gases under pressure in processes requiring reliable containment.
- Compressed gas distribution networks: Design and implementation of cylinders for bulk gas transport.
- Safety-critical environments: Adherence to updated testing and material standards reduces risks in operational gas containment.
By following this standard, industries benefit from:
- Enhanced safety margins
- Improved product reliability and traceability
- Compliance with international regulatory frameworks
- Reduced risk of failures due to corrosion or weld defects
Related Standards
Implementing ISO 21172-1:2015/Amd 1:2018 also involves familiarity with related and referenced standards to ensure comprehensive compliance:
- ISO 21172 series: Covers welded steel pressure drums up to 3,000 litres, including parts for higher capacity cylinders.
- ISO 148-1: Charpy impact testing to assess material toughness.
- ISO 17636-1: Radiographic weld testing for quality assurance.
- ISO 11363-1: Valve connection taper thread specifications for gas cylinders.
- ISO 19232-3: Defines radiographic image quality in non-destructive testing.
- ISO 3452-1: Penetrant testing principles for surface defect detection.
- ISO 15614-1: Welding procedure qualification for steel materials.
- ASTM A285/ASTM A285M-12: Specification for pressure vessel carbon steel plates.
Adherence to ISO 21172-1:2015/Amd 1:2018 facilitates the production of welded steel gas cylinders that meet rigorous international safety, durability, and performance requirements. This amendment underscores ISO's commitment to continuous improvements in gas cylinder technology and manufacturing standards, benefiting manufacturers, regulators, and end users worldwide.
