304L ASTM A269 Seamless Tube Polished Finish 1" for Clean Fluid System

SMLSCO implements a comprehensive quality control process to meet strict requirements for clean pipelines. From raw material procurement to final inspection, every step is strictly monitored:

• Raw materials verified with certification
• Precise control of dimensional tolerances and surface roughness
• 100% eddy current testing and visual inspection
• Archived inspection records for full transparency

SMLSCO seamless tubes undergo:

• Multi-pass inner and outer wall polishing for high surface smoothness
• Bright annealing process under controlled atmosphere
• Elimination of cold working stress
• Formation of bright oxide-free surfaces

This ensures the highest cleanliness and corrosion resistance for high-end applications.

304L stainless steel features:

• Excellent universal corrosion resistance
• Good formability and outstanding welding performance
• Low-carbon version resists intergranular corrosion after welding
• No post-weld heat treatment required

For most non-strong acid-base clean fluid environments, 304L provides a highly cost-effective and reliable solution.

304 stainless steel polishing tube is essential for modern clean fluid systems requiring high hygiene and purity. Key benefits include:

• Precision polished inner/outer surfaces prevent bacterial adhesion
• Mirror-like smoothness reduces biofilm formation
• Ensures thorough cleaning (CIP) and sterilization (SIP)
• Widely used in pharmaceutical, food & beverage, and semiconductor industries
