Safety Guidelines

When it comes to the design and evaluation of instrumentation and control systems installed for safety purposes, no easy answers exist. A methodical, team-oriented life-cycle approach is required. Chaowei Valves provide systematic safety guidelines for valve selection,storage ,installation,commissioning, operations, maintenance and replacement.

Installation and commissioning. This step ensures the system is installed per the design and performs per the safety requirements specification. Before a system is shipped from the factory, it must be thoroughly tested for proper operation. If any changes are required, they should be made at the factory, not at the installation site.

Operations and maintenance. Every system requires periodic maintenance to function properly. Not all faults are self-revealing, so every safety system must be periodically tested to make sure it will respond properly to an actual demand. The frequency of inspection and testing should have been determined earlier in the life cycle. All testing must be documented.
