Quality Control System of SMLSCO Polished Tube
SMLSCO are well aware of the strict quality requirements for clean pipelines, and therefore implement a comprehensive quality control process. From purchasing raw materials without certification, to precise control of dimensional tolerances and surface roughness during production, to 100% eddy current testing and visual inspection before shipment of finished products, every step is strictly monitored. We ensure that every pipe delivered has no surface defects and precise dimensions. All inspection records are archived for future reference, providing customers with a completely transparent and trustworthy quality commitment.

Precision Polishing and Bright Annealed Process

SMLSCO seamless tubes undergo precision multi pass inner and outer wall polishing treatment to ensure high surface smoothness, no scratches, effectively reducing fluid resistance and preventing scaling, which is crucial for heat exchange efficiency. Subsequently, a bright annealing process was employed to perform heat treatment under controlled atmosphere, eliminating cold working stress and restoring the excellent mechanical properties of the material. This process can form a bright oxide free surface, ensuring the highest cleanliness and corrosion resistance of the pipe, providing reliable guarantee for high-end applications.

This highly smooth surface also ensures the thoroughness of online cleaning (CIP) and online sterilization (SIP), without any hygiene blind spots. With its excellent corrosion resistance and outstanding cost-effectiveness, 304 polished tubes are widely used in purified water systems in the pharmaceutical industry, material transportation pipelines in the food and beverage industry, and ultra pure water (UPW) pipelines in the semiconductor and electronics industries.

Choosing high-quality 304 polishing tubes is a crucial step in ensuring the purity of the fluid medium, compliance with industry hygiene standards, and guaranteeing the quality of the final product.
