Foreword
GB/T 5099 "steel seamless gas cylinder" is divided into the following four sections.
--- Part 1. After quenching and tempering the tensile strength of less than 1100MPa cylinder;
--- Part 2. Tempered steel after quenching tempering greater than or equal to 1100MPa;
--- Part 3. Normalized steel cylinder;
--- Part 4. Stainless steel seamless gas cylinder.
This section GB/T 5099 Part 3.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 5099-1994 "seamless steel cylinder" section.
This section compared with GB/T 5099-1994 main changes are as follows.
--- Adjust the scope of the standard.
a) Nominal work pressure from the original 8MPa ~ 30MPa changed to not more than 15MPa;
b) the nominal water volume from the original 0.4L ~ 80L changed to 0.5L ~ 150L;
c) the use of ambient temperature is set at -20 ℃ ~ 60 ℃;
d) By deleting "not applicable for fire extinguishing cylinders".
--- Expand the scope of cylinder specifications.
a) the deletion of the requirement for diameter subdivision;
b) Delete the list of filling media and the requirements for pressure binning.
--- Change the wall thickness calculation formula.
--- Remove the bottom of the bottle finite element calculation requirements.
--- A number of provisions for the "no more than 500 plus the number of destructive test cylinders."
--- After the bulk heat treatment of the bulk metallographic examination changed to type test requirements.
--- Increased the seamless steel pipe made of the bottom of the sealing test requirements.
--- Hydraulic test requires the use of external measurement of volume deformation rate test.
--- Remove the bottle after heat treatment hardness test requirements.
--- Cylinder stamp marks the measured water volume changes to the nominal water volume.
--- Increased bottle valve assembly torque appendix.
--- Added ultrasonic testing methods and assessment of the appendix.
--- Added magnetic particle testing methods and assessment of the appendix.
--- Increased flattening test method appendix.
--- Added the description of the inner and outer surface defects and assessment appendix.
This section uses the redrafted law reference ISO 9809-3.2010 "cylinder refillable seamless steel cylinder design, manufacture and test
Inspection Part 3. Normalized steel cylinders ", the degree of agreement with ISO 9809-3.2010 is not equivalent.
