1 Scope
1.1 This standard specifies the materials, design, manufacturing, test methods,
inspection rules, marking, exit-factory documents, storage and transportation
requirements for tube skid containers.
1.2 This standard applies to tube skid containers, which are composed of the following
large-volume steel seamless gas cylinders (hereinafter referred to as gas cylinders)
connected to frames:
a) The operating ambient temperature is -40 °C ~ 60 °C;
b) The nominal working pressure of the gas cylinder is 10 MPa ~ 30 MPa; the
nominal working pressure of the gas cylinder used for filling oxygen shall not be
greater than 20 MPa;
c) The nominal water volume of the gas cylinder is 150 L ~ 4200 L;
d) The filling medium is natural gas, hydrogen, oxygen, air, nitrogen, argon, helium,
neon, krypton and other compressed gases.
1.3 This standard applies to road, railway, water transport and to tube skid containers
used for multimodal transport in these modes.
1.4 Gas cylinder containers, which have a nominal water volume of 150 L ~ 1000 L and
a sum of nominal water volumes of each group of gas cylinders not exceeding 3000 L,
shall also comply with the provisions of Appendix A.
1.5 This standard does not apply to the following tube skid containers:
a) Filled with liquefied gas, dissolved gas, extremely toxic medium;
b) The gas cylinder is a filament-wound gas cylinder.
2 Normative references
The following documents are essential to the application of this document. For the dated
documents, only the versions with the dates indicated are applicable to this document;
for the undated documents, only the latest version (including all the amendments) is
applicable to this standard.
5.1.5 The material manufacturer shall provide the material quality certificate to the tube
skid container manufacturer. The content of the material quality certificate shall be
complete and clear; it shall be printed with a traceable information marking or label; it
shall have the quality inspection seal of the material manufacturer.
5.1.6 When the tube skid container manufacturer obtains materials from non-material
manufacturers, it shall obtain the original material quality certificate provided by the
material manufacturer OR a copy stamped with the official seal of the material business
organization and the signature (seal) of the responsible person.
5.1.7 The tube skid container manufacturer shall be responsible for the authenticity and
consistency of the materials and material quality certificates obtained.
5.1.8 When imported pressure piping components are used, they shall comply with the
requirements of corresponding safety technical specifications and standards. Pressure
piping components imported for the first time shall be type tested by a pressure piping
component type testing agency, which is approved by the State Administration for
Market Regulation.
5.2 Gas cylinder
5.2.1 Cylinder body
5.2.1.1 Seamless steel pipes for cylinders shall not only comply with the requirements
of TSG R0006 and GB/T 33145, but also comply with the requirements of this standard.
5.2.1.2 The cylinder body shall be made of a single seamless steel pipe; splicing is not
allowed.
5.2.1.3 For seamless steel pipes used to fill hydrogen or natural gas and other medium
that are prone to brittleness and stress corrosion, the chemical composition of the
material shall meet the following requirements: the content of carbon (C) is not more
than 0.350%, phosphorus (P) is not more than 0.020%, sulfur (S) is not more than
0.010%, the total content of sulfur and phosphorus (S + P) is not more than 0.025%.
5.2.1.4 Except for seamless steel pipes filled with medium other than those specified in
5.2.1.3, the chemical composition of the material shall meet the following requirements:
