The circulating water system should control the pH value between 7.0 and 8.5, with chloride ions ≤ 200 ppm.
5.6 Regular testing
The refrigeration system undergoes an annual nitrogen pressure test and records pressure changes.
Medical gas pipelines should be wiped and sampled with white silk cloth every six months to check their cleanliness.
Regularly measure the flow rate, pressure, and water quality of the water pipe system.
Suggestions for on-site emergency response
Small aperture leakage: A compression type repair joint can be used (pressure rating needs to be confirmed), but it is best to replace the entire section.
Internal blockage: If the blockage is soft (grease, moisture), high-pressure blowing or specialized cleaning agents can be used; If it is hard oxide skin, the pipe section must be replaced.
Corrosion perforation: Replace the corrosion section while inspecting and eliminating the corrosion source (such as grounding current, chemical medium).
Bending crack: Cut off the crack segment, connect it with a direct joint, and increase the radius or use a soft tube when re bending.
