What is the pressure at which chlorine cylinders should be tested?

The correct pressure at which chlorine cylinders should be tested is 800 psi. Testing at this pressure is crucial because it is a standard requirement to ensure the integrity and safety of the cylinder under pressure. Chlorine, being a hazardous material, necessitates strict compliance with safety protocols to prevent leaks or failures that could lead to dangerous situations.

A testing pressure of 800 psi allows for the detection of any potential weaknesses or defects in the cylinder walls, threads, or other critical points. This ensures that the cylinder can safely contain the chlorine gas during its storage and use. Such testing is typically specified by industry regulations and standards to safeguard against accidents in environments where chlorine is utilized, such as water treatment facilities or chemical manufacturing plants.

The other values mentioned, such as 600 psi, 1000 psi, and 1200 psi, do not align with standard testing protocols for chlorine cylinders and may not provide the necessary assurance of the cylinder's safety and effectiveness. Therefore, adherence to the 800 psi standard is essential for maintaining safety in utilities maintenance operations that involve the handling of chlorine.
