GB/T 5099.1-2017Seamless steel gas cylinders -- Part 1: Quenched and tempered steel cylinders with tensile strengthless than 1 100 MPa (English PDF)

Foreword

GB/T 5099 "seamless steel gas cylinder" is divided into the following 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 1.

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 content changes as follows.

--- Adjust the scope of the standard.

a) Nominal working pressure from the original 8MPa ~ 30MPa changed to not more than 30MPa;

b) the nominal water volume from the original 0.4L ~ 80L changed to 0.5L ~ 150L;

c) Dressing media increase can be used for mixed gas;

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.

--- The number of each batch is specified as "no more than.200 plus destructive test cylinder number."

--- 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.

--- 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.
