10L 150bar CO2 Bottle Argon Nitrogen Helium N2O Air Cylinder

 Leak test of gas cylinders:

The manufacturer shall employ such manufacturing techniques and apply such tests as will demonstrate to the satisfaction of the inspector that the cylinders do not leak.

Size inspection: (1) wall thickness: the wall thickness of any point shall not be less than the minimum wall thickness specified;  (2) roundness of cylinder ≤ 2% of average outer diameter (3) straightness of cylinder ≤ 3‰ of bottle length;  (4) The perpendicularity of the bottle is less than or equal to 10‰ of the bottle length;  (5) Average diameter ≤ ±1% of nominal design diameter;  

Surface defects: internal and external surface defects that may negatively affect the safe use of cylinders, see ISO9809-1 

1、Minimum order quantity: 100 only

2、we are the manufacturer：Products can be exported to countries or regions:China, Southeast Asia, Middle East, Asia, Africa, Europe, Oceania, America

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

4、For cylinders with base ends formed by spinning, the following are three examples of typical testing procedures:

⎯ a pneumatic leakage test where the bottom end shall be clean and free from all moisture on the test pressure side. The inside area of the cylinder bottom surrounding the closure shall be subjected to a pressure equal to at least two thirds of the test pressure of the cylinder for a minimum of 1 min; this area shall be not less than 20 mm in diameter around the closure and at least 6 % of the total bottom area. The opposite side shall be covered with water or another suitable medium and closely examined for indication of leakage; cylinders that leak shall be rejected; 

⎯ a low pressure pneumatic test; 

⎯ a helium leak test.

5、Specialty gases: 40 billion market, fast growth;  High barriers correspond to high profitability

Specialty gases, as opposed to bulk gases, are usually sold in bottled form to downstream customers

Characteristics of special gases: 

1) the production process is difficult; 

2) More categories, less single product consumption; 

3) Customers are mainly concentrated in emerging growth areas with fast demand growth; 

4) The unit price of the product is high, and the customer price sensitivity is not as good as Puqi; 

5) The profitability is much higher than Puqi.
