What are the difficulties in quality control during the processing of stainless steel bright tubes?
1. Surface defect control:
Cold processing can easily produce black spots and scratches, so it is necessary to strictly clean the rollers and molds;
Impure annealing atmosphere may lead to oxidation color difference, and real-time monitoring of gas purity is required.
2. Dimensional accuracy guarantee:
The wall thickness tolerance after cold rolling needs to be controlled within ± 0.05mm, relying on high-precision rolling mills;
Thin walled tubes (such as capillary tubes) are prone to deformation and require customized support fixtures.
3. Cleanliness management:
After welding, water cooling is required to prevent overheating and deformation, and a dedicated dust removal system is needed for polishing dust;
Medical grade pipe fittings require production in clean workshops to avoid microbial contamination.
