304 Stainless Steel Seamless Pipe Usage:
Milk and food industry, pharmaceutical industry, special inner surface requirements of the industry.
Process characteristics: inner bead leveling treatment, solution treatment, inner surface electropolishing
Performance characteristics: the internal surface roughness Ra is more than 0.2, the wall hanging residue is small, easy to clean, prevent bacterial growth, electrolytic polishing has a passivation effect, and the inner wall has good defense performance.
Testing methods: lateral, longitudinal flattening, reverse flattening, hydrostatic testing or eddy current testing, mechanical properties testing, internal surface roughness testing.
