Tips for safe use of gas cylinders:
(1) During the transportation and loading and unloading of gas cylinders, tighten the bottle cap and lightly load and unload them. Throwing, sliding or bumping are strictly prohibited.

(2) Gas bottles should be properly fixed in the car. Automobile loading cylinders should generally be placed horizontally with the head facing one side. The loading height should not exceed the height of the carriage; Upright discharge, carriage height should not be less than 2/3 of bottle height.

Portable gas cylinders

1、Our seamless steel cylinders are widely used in industry, medical devices, fire fighting and scientific research

2、Minimum order quantity: 100 only

3、Impact test of gas tanks:

1)、This  part  of  ISO 9809  provides  a  specification  for  the  design,  manufacture,  inspection  and  testing  of  a seamless steel cylinder for worldwide  usage. The objective  is to  balance design and economic efficiency against international acceptance and universal utility.

2)、ISO 9809 (all parts) aims to eliminate existing concerns about climate, duplicate inspections and restrictions because of a lack of definitive  International Standards. This part of ISO 9809 should not be construed as reflecting on the suitability of the practice of any nation or region.

3)、This part of ISO 9809 addresses the general requirements on design, construction and initial inspection and testing  of  pressure  receptacles  of the  United  Nations  Recommendations  on  the  Transport of Dangerous Goods: Model Regulations.

4)、For longitudinal tests, the test piece shall be machined all over (on six faces). If the wall thickness does not permit a final test piece width of 10 mm, the width shall be as near as practicable to the nominal thickness of the cylinder wall. The test pieces taken in the transverse direction shall be machined on four faces only, the outer face of the cylinder wall unmachined and the inner face optionally machined as shown in Figure 8.

7In GB 5099-85, elongation after fracture is a relative requirement for strength, and D5 requires no less than 14% ~ 18%.

Notch toughness and impact test notch toughness refers to its plastic yield capacity when there is a large stress concentration at the bottom of the notch, and impact toughness value is generally used for comparison.

The influencing factors of impact toughness are carbon content, alloying element content, gas content, impurity content, hardness, microstructure, test temperature and specimen size. Maximum notch toughness can be obtained by completely quenching and tempering fine grain, low carbon, completely deoxidized alloy steel.

The United States believes that the impact values obtained from different sizes of specimens may not reflect the real situation. Therefore, it is not required to do this test, as long as the tensile test and flattening test to meet the requirements of the United States.

The impact test method varies from country to country. Currently, the national standard of gas cylinders in our factory has specific provisions on the specimen size and slot orientation. U-shaped notch is used at -20℃, and V-shaped notch is used at -50℃, and there is no corresponding relationship between the impact toughness values of the two.
