Question 1

Do you supply valves or related accessories with the cylinders?

Accepted Answer

According to the customer's needs, we can provide customized valves or assist in the assembly of customer-supplied parts.

Question 2

Are your cylinders suitable for medical, scuba, or industrial applications?

Accepted Answer

It is important to confirm whether the local regulations at the sales origin are in compliance.

Question 3

Are your cylinders corrosion-resistant? What types of gases are they compatible with?

Accepted Answer

Cylinders are primarily compatible with high-purity, non-corrosive, or low-corrosive gases, such as:

Oxygen (O₂)
Nitrogen (N₂)
Carbon Dioxide (CO₂)
Argon (Ar)
Compressed Air
Medical Gases
Specialty inert gases, etc.

Question 4

What is the service life of your cylinders? How many refill cycles are they rated for?

Accepted Answer

In Taiwan, cylinders do not have a fixed expiration period. They can be reused and refilled as long as they successfully pass the required hydrostatic test every three years. The suitability for continued use also depends on the condition of the valve.

Question 5

What sizes or capacities are available? Do you offer customized capacities?

Accepted Answer

We offer cylinders with water capacities ranging from 130cc to 3000cc, and we also accept custom orders and assist with certification applications.

Question 6

What is the pressure range of your aluminum cylinders? What is the maximum working pressure?
