Welding or brazing for any purpose in any respect is prohibited except that welding is licensed with the attachment of neckrings and footrings that happen to be nonpressure parts, and only towards the tops and bottoms of cylinders.
All spun cylinders and plugged cylinders has to be analyzed for leakage by fuel or air strain right after the bottom has long been cleaned and is also free of charge from all humidity, issue to the following disorders and restrictions:
suggest the packaging identification markings essential by this element including, in which relevant, the name and tackle or symbol of your packaging company or approval company.
(iv) Further more supplied that wall stress for cylinders acquiring copper brazed longitudinal seams may well not exceed ninety five per cent of any of the above values. Measured wall thickness may not include things like galvanizing or other protecting coating.
Cylinders have to be made by finest appliances and procedures. No defect is permitted that is probably going to weaken the completed cylinder appreciably. A fairly clean and uniform area end is required. The thickness of your spun bottom is, beneath no situation, to generally be lower than two situations the minimum wall thickness on the cylindrical shell; this sort of base thickness needs to be calculated click here within just an area bounded by a line representing the points of Call among the cylinder and floor in the event the cylinder is within a vertical placement.
(one) Each opening in the container should be presented using a fitting, boss or pad of weldable chrome steel securely attached to your container by fusion welding.

Product need to be discovered by any appropriate process besides that plates and billets for hot-drawn cylinders need to be marked with the warmth variety.
Inspection need to be executed on The within of every container right before closing and externally on Each and every finished container after heat procedure.
(iv) Lasting volumetric growth may well not exceed ten % of the overall volumetric growth at exam strain.
(i) The porous product may well not disintegrate or sag when moist with solvent or when subjected to normal company;
(6) Other markings are approved offered They may be produced in small strain places other than the aspect wall and are not of a dimensions and depth which will generate hazardous stress concentrations. These types of marks might not conflict with any DOT demanded markings.
