2.25M3 15 litre ISO9809 150bar 37MN Oxygen tank gas cylinder 

The company adheres to the business purpose of honoring contract, keeping promise, quality first and customer first, to create a high, precise and sophisticated global manufacturer of gas storage containers.

Pressure cycling test:The cylinder shall actually experience the maximum and minimum cyclic pressures during the test. 

The frequency of reversals of pressure shall not exceed 0,25 Hz (15 cycles/min). The temperature measured on the outside surface of the cylinder shall not exceed 50 °C during the test. 

In order to improve the company's market competitiveness and serve the seamless cylinder industry innovation solutions, the company set up seamless cylinder research and development, testing in one of the experimental center.

2、Oxygen cylinder body height 932mm; Oxygen cylinder body weight 16.8KG; Maximum oxygen tank capacity is 2.25m3 (2250 litres); Oxygen cylinder mouth thread PZ27.8; 25E; 3/4-14 NGT, etc.; The minimum design wall thickness of oxygen cylinder is 4.3mm;

3、Alias: 15 litre gas cylinders; 2.25 m3 Oxygen tanks. 15 litre Oxygen cylinders; 15L litre Oxygen tanks; 150bar 37mn Oxygen tanks

4、Heat treatment：If the failure is considered to be due to the heat treatment applied, the manufacturer may subject all 

the cylinders representing the nature of the failure to a further heat treatment, e.g. if the failure is in a 

test representing the prototype or batch cylinders, test failure shall require reheat treatment of all the 

represented cylinders prior to retesting. 

This heat treatment shall consist of re-normalizing or re-normalizing and tempering or re-tempering.

Shandong Hongsheng Pressure Vessel Co., Ltd. is willing to be your long-term partner and chief cylinder safety officer, and jointly escort your cylinder safety.

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、Cylinder water pressure testing process: under the Ph of the hydraulic pressure test, the cylinder pressure holding time is not less than 30s, the pressure gauge pointer shall not fall back, and the cylinder body shall not leak or obvious deformation.  Residual deformation rate of cylinder volume is not more than 5%. 

5、Tempering toughening heat treatment which follows normalizing, in which the cylinder is heated to a uniform temperature below the lower critical point, Ac1, of the steel

6、Pressure cycling test ：After the test, the cylinder bases shall be sectioned to measure the thickness and to ensure that this thickness is sufficiently close to the minimum thickness prescribed in the design and shall be within the usual production tolerances. In no case shall the actual base thickness exceed the minimum value(s) specified on the drawing by more than 15 %. The test shall be considered satisfactory if the cylinders attain the required number of cycles without developing a leak.
