Standard metal test sheet suspended in the test vessel, on-site
inspection heat exchanger or test pipeline for corrosion
determination. It is used to detect or evaluate the corrosion
condition of cooling water system. Generally, the pre processed
and weighed metal test pieces are placed in the test system for a
period of time, and then taken out to observe the corrosion, clean
and weigh. Determine the weight loss degree of metal corrosion,
type of corrosion and pitting depth, etc. In addition to the
influence of corrosive media, the data of metal hanging pieces are
also related to the surface treatment, placement position, exposure
time and metallurgical method of samples.
