 Inspection And Test
Raw Material Inspection:
1. Check the material supplier's mill test certificates
2. Check the material's quantity, size, surface condition
3. Conduct chemical analysis and mechanical property test

ASME SA789 S32205 S31803 A269 SA213 Stainless Steel Seamless Pipe


Process Inspection:
1. Inspect single work-piece's dimension, levelness, bend
degree, hole size, hole location, etc.
2. Inspect the work-piece's welding result 

Cleaning Result Inspection:
After the work piece pass the process inspection, then go to cleaning to wipe out its oil&grease, dust, and other contaminants. Inspection method:
1. Visual inspection 
2. Wipe test 
3. Black light test
4. Mirror test (if need)
Assembly Inspection:
After cleaning inspection is good, then assemble on set to inspect its overall levelness, dimension, etc.Water Test:
Water test is a good way to check the distributor's working performance. The test items includes:
1. Liquid height in trough
2. Used time of one hole to fill the container
3. Calculate the coefficient variance(CV)
Package Inspection:
1. Check the small parts quantity according to packing list
2. Check the protect method of the internals
