ASME BPE Stainless Steel Sanitary Tube is a critical fluid conveyance component due to its extremely high hygienic standards and stringent surface treatment requirements. This tubing is produced with advanced mechanical and electropolishing processes, achieving an internal surface roughness of Ra ≤ 0.4 μm, effectively preventing microbial adhesion and biofilm formation, thereby ensuring a sterile production environment compliant with GMP and FDA regulations.
The ASME BPE standard comprehensively regulates the material composition, welding processes, surface roughness, and system design of tubing, emphasizing that piping should support steam-in-place (SIP) sterilization and clean-in-place (CIP) cleaning to maintain a highly clean and stable system. Tubing that meets the ASME BPE standard is key to ensuring the quality and safety of biopharmaceutical products.
The 3-A SSI standard is also widely referenced in the biopharmaceutical industry to assist in designing equipment and piping systems that meet industrial hygiene and cleanliness requirements. Rigorous material selection and precise surface finishing ensure tubing maintains corrosion resistance and surface integrity throughout multiple CIP/SIP cycles.
Core Hygienic Standards：
·ASME BPE(Comprehensive biopharmaceutical equipment standard covering materials, welding, surface finish, and system design)
·3-A SSI(Widely used reference standard for high hygienic requirements in biopharma)
Surface Treatment Requirements：
·Typical internal surface roughness requirement of Ra ≤ 0.4 μm or better
·Electropolishing enhances corrosion resistance and reduces microbial adhesion
·Orbital welded with polished welds to ensure crevice-free, seamless tubing suitable for sterile manufacturing
Material：
·Primarily use low-carbon, high-purity 316L stainless steel
Cleaning and Sterilization Compatibility：
·Designed to support SIP (steam-in-place) sterilization and CIP (clean-in-place) cleaning processes
·Tubes undergo pickling, passivation, and sterile packaging to maintain cleanliness
Dimensions and Connections：
·Precision control of tube dimensions and tolerances to ensure fluid dynamics and sealing requirements
·Common hygienic connections include Tri-Clamp and ISO Clamp, meeting aseptic connection demands
Quality Inspection and Traceability：
·Comprehensive checks including dimensional accuracy, surface finish, weld quality, and material properties
·Provides detailed validation and traceability documentation to satisfy regulatory inspections
