What material is used for Alsafe's aluminum cylinders?
Alsafe’s aluminum cylinders are constructed with aluminium alloy 6061 T-6.
What are the guidelines for filling and refilling Alsafe aluminum cylinders?
When filling and refilling Alsafe cylinders, the pressure should not exceed the nominal working pressure and should be done at a temperature between -40℃ to 60℃. The threads and interior of the cylinder should be kept dry and free from any contamination.
What are the design and construction standards for Alsafe gas cylinders?
Alsafe gas cylinders are designed and constructed in accordance with International and China domestic Standards as applicable. These Standards define the cylinders’ material, method of manufacture, test pressure, maximum permissible filled pressure, and method of periodic inspection.
What are the guidelines for handling cylinders?
Cylinders should be handled carefully to avoid impact damage. They should not be dropped or have heavy objects fall on them. Impact damage can potentially reduce the cylinder wall thickness, leading to premature cylinder rupture.
What are the markings on the cylinders?
For seamless cylinders, permanent identification markings are usually found on the shoulder of the cylinders.
The stamp markings generally include the following information: Cylinder Serial Number, Manufacturer’s Identification, Hydraulic Test Pressure (in bar), Working Pressure (in bar), Empty Cylinder Weight (in kg), Actual Water Capacity (in L), Design Wall Thickness (in mm), Year and Month of Manufacture, and the Manufacturing Standard.
What are the special care instructions for diving cylinders?
After each use, wash the cylinder and its accessories in freshwater and dry them, especially after use in seawater. If seawater accidentally contacts the cylinder interior, rinse it with clean freshwater immediately for 2-3 times, then blow dry the interior with clean, dry air.
What are the guidelines for maintaining frequently used scuba cylinders?
For frequently used scuba cylinders, remove all components, clean and dry thoroughly at least once a month. It is recommended to remove the cylinder valve and inspect the cylinder at least every 3 months. If the cylinder shows signs of damage or corrosion, it should not be used.
