The requirements for stainless steel materials of medical purified water equipment are very strict 

The surface roughness of coagulating sedimentation equipment for pharmaceutical purified water is an important part of the stainless steel material certificate, and is also one of the main inspection items of raw materials when they are put into storage. For pharmaceutical pure water equipment, its surface roughness should meet the actual requirements of pharmaceutical water production, cleaning and sterilization.

The rougher the inner surface of the pipeline of the coagulating sedimentation equipment for pharmaceutical purified water, the easier it is to provide favorable conditions for the propagation of microorganisms, form biofilms that are difficult to remove, and cause high microbial content in the system. At the same time, the rougher the system surface is, it will also affect the cleaning and sterilization of equipment. Therefore, the surface roughness of medical purified water equipment and pipes should be strictly controlled.

Generally, the internal surface finish of pipeline Ra ≤ 0.6; External surface finish Ra ≤ 0.8.

Then, how to detect the roughness of the pipeline of the coagulating sedimentation equipment for pharmaceutical purified water? During testing, place the roughness tester on the part to be measured first, and let the contact touch the object to be measured. Adjust the height of the adjustable bracket on the right side of the instrument so that the cursor of the contact position on the left side of the display screen points to zero. Press the "START" measurement button, and take photos after the instrument test is completed. Note: Do not shake or move the detector during the test, otherwise it needs to be re tested.

The requirements for stainless steel materials of coagulating sedimentation equipment for pharmaceutical purified water are very strict

In the coagulant sedimentation equipment for pharmaceutical purified water, roughness inspection shall be carried out on the inner and outer walls of raw water tank, multi-media filter, softener, activated carbon filter, purified water tank, pretreatment pipeline, reverse osmosis pipeline, EDI pipeline and purified water return pipeline, and related pictures The position and value shall be compiled into the Inspection Record of the Roughness of the Outer and Inner Walls of Pipes and Tanks, which shall be provided to the customer as an attachment of FAT and SAT to ensure that the materials are traceable and verifiable.
