GB5099 Emergency Oxygen Bottles Made In China Gas Cylinders
Repeated heat treatment shall meet the following requirements:
1) Normalizing bottle should be tempered or secondary normalizing; ;
2) normalizing and tempering bottles should be re-tempering or secondary normalizing and tempering;
3) Tempering and tempering bottles should be re-tempered or re-tempered.
Tips for safe use of gas cylinders:
(1) The storage period of gas cylinders containing easy polymerization reaction should be specified.
(2) Do not place gas cylinders in places where electricity may be conductive.
(3) Why should the cylinder be lightly loaded and unloaded? Throwing, rolling or collision is strictly prohibited?
Due to violent collision or impact of gas cylinders, there will be an explosion accident, the consequences will be very serious
Shandong Hongsheng is willing to be your long-term partner and chief cylinder safety officer, and jointly escort your cylinder safety.
Whenever repeated heat treatment is carried out, the minimum design wall thickness of the finished product should be guaranteed (e.g., after shot peening or surface treatment). .
1、Minimum order quantity: 100 only
2、Use cylinders:Our seamless steel cylinders are widely used in industry, medical devices, fire fighting and scientific research
3、We are China’s gas cylinder production factory, product sales:China, Southeast Asia, Middle East, Asia, Africa, Europe, Oceania, America
4、Common nonconformance points in gas bottles production
a/Pitting:Severe surface corrosion
b/Non-conformity with design drawing:
c/Neck ring not secure:Neck ring turns under application of low torque or pulls off under low axial load
d/Arc or torch burns:Partial burning of the cylinder metal, the addition of weld metal or the removal of metal by scarfing or cratering
5、Manufacturing defect
The defects and definitions that occur most of the time are listed in Table B.1. The table includes limits on repair or rejection. These rejection limits contain considerable experience and apply to all sizes and types of cylinders and service situations. But some user-specified cylinder specifications, types, or specific service situations require stricter guidelines.
Rejected cylinders
All rejected cylinders are not fit for their original purpose.
Gas cylinders used for other purposes may be manufactured using rejectionist cylinders.
