Description (English):

This document specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes, examination and testing at time of manufacture for refillable seamless steel gas cylinders and tubes with water capacities up to and including 450 l. It is applicable to cylinders and tubes for compressed, liquefied and dissolved gases and for quenched and tempered steel cylinders and tubes with a maximum actual tensile strength Rma of less than 1 100 MPa.

Abstract

Overview

ISO 9809-1:2019 - “Gas cylinders - Design, construction and testing of refillable seamless steel gas cylinders and tubes - Part 1” specifies minimum requirements for quenched and tempered seamless steel cylinders and tubes with a maximum actual tensile strength (Rma) of less than 1 100 MPa and water capacities up to and including 450 L. This third-edition (2019) international standard covers material selection, design, manufacturing, inspection and testing at the time of manufacture for cylinders used for compressed, liquefied and dissolved gases.

Key topics and requirements

Materials and metallurgy: minimum material controls, chemical composition checks, typical steel types and heat-treatment guidance for quenched and tempered steels.
Design rules: requirements for shell thickness, convex and concave end designs, neck, foot and neck rings, limitations on tensile strength, and required design drawings.
Manufacturing and workmanship: wall thickness tolerances, surface imperfection criteria, straightness, out-of-roundness and diameter controls.
Inspection & nondestructive testing: ultrasonic examination procedures and acceptance criteria (Annex B), evaluation of manufacturing imperfections (Annex A).
Type approval & batch testing: prototype testing, pressure cycling, bend/flattening tests (prototype), batch sampling, tensile, impact and hydraulic burst tests, proof pressure, volumetric expansion, hardness, leak and capacity checks.
Thread and mechanical checks: new thread test requirements and informative shear strength/torque guidance (Annex G).
Certification & marking: type approval certificates, batch/acceptance certificates and mandatory marking information for traceability.

Applications and who uses it

ISO 9809-1:2019 is used by:

Cylinder manufacturers for design, process control and production acceptance.
Design and engineering teams specifying safe cylinder geometry and materials.
Testing and inspection laboratories performing batch and proof tests (hydraulic, tensile, impact, ultrasonic).
Certification bodies and regulatory authorities issuing type approvals and conformity assessments.
Gas suppliers, transporters and end-users who require cylinders compliant with international safety and transport regulations (including reference to UN Model Regulations).

Related standards

Other parts of the ISO 9809 series (other materials and strength classes).
UN Model Regulations on the transport of dangerous goods (standard is written to be referenceable).
ISO/TC 58 technical committee publications for gas cylinder standardization.

Keywords: ISO 9809-1:2019, gas cylinders, seamless steel, quenched and tempered, design, construction, testing, refillable cylinders, tensile strength
