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.

Material Properties of 304L
304L stainless steel is one of the most widely used sanitary grade pipeline materials, known for its excellent universal corrosion resistance, good formability, and outstanding welding performance. As a low-carbon (L-grade) version, it can effectively resist intergranular corrosion after welding without the need for post weld heat treatment, ensuring the integrity and cleanliness of pipeline connections. For most non strong acid-base clean fluid environments, 304L provides a highly cost-effective and reliable solution.
304L Polished Tube in Clean Fluid System
304 stainless steel polishing tube is the basic material for building modern clean fluid systems, especially in fields that require high hygiene and purity. Its core value lies in the precision polished inner and outer surfaces. This mirror like smooth pipe wall can effectively prevent bacterial adhesion and biofilm formation, greatly reducing the risk of cross contamination.
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.
Core Advantages of SMLSCO
We have become your reliable partner with three core advantages.
Professional Packaging Solutions
To ensure that sanitary grade tubes remain in a highly clean state during transportation and storage, we adopt the highest standard packaging solution. Each seamless tube that has passed inspection will be individually placed in a sealed plastic bag to isolate external dust and moisture. Both ends of the tube are equipped with sturdy plastic protective caps to prevent deformation or damage to the ports. Finally, all tubes will be neatly packed into sturdy plywood wooden boxes to ensure safe and clean delivery to the customer's site.
