Rho CO2 Argon Tanks Nitrogen Helium N2O Air O2 Cylinder
Several types of defects that may occur during the manufacture of seamless cylinders.
The defect may be mechanical or material. That is, basic materials used, processing technology, heat treatment control, bottle finishing, or stamping and other processing factors.
The purpose of this appendix is to identify the most common manufacturing defects and to provide rejection guidelines to inspectors performing visual inspections.
However, inspectors must have extensive experience and good judgment to detect, assess and judge a defect during visual inspection.
1、Minimum de commande : 100 seulement
2、Utilisation des cylindres : nos cylindres en acier sans soudure sont largement utilisés dans l'industrie, les appareils médicaux, la lutte contre les incendies et la recherche scientifique.
3、We are China’s gas cylinder production factory,
product sales:China, Southeast Asia, Middle East, Asia, Africa, Europe, Oceania, America
4、Points de non-conformité courants dans la production de bouteilles de gaz
a/Internal cracks in base:Splits in the metal of the bottom of the cylinder in star form
⎯ Lorsqu'il n'est pas possible de l'enlever dans les limites de la tolérance d'épaisseur
⎯ Lorsqu'il est possible de l'enlever dans les limites de la tolérance d'épaisseur
b/”Orange peel” surface:Orange peel appearance due to discontinuous metal flow
⎯ If sharp cracks are visible in the orange peel surface
5、Visual inspection of cylinders both inside and outside must be complete.
Metal surfaces, especially inside cylinders, should be completely clean and dry and free of oxides, corrosion and rust, which could cause serious defects. Where necessary, clean surfaces in an appropriate manner prior to further testing.
Suitable lighting sources of sufficient intensity should be used.
After cylinder threading is complete, check the inside of the bottleneck for defects using an inner hole viewer, dental profile, or other appropriate tool
