316L 304 Stainless Steel Sheet Metal Fabrication Medical Reactor Equipment Shell Custom Processing

Before we dive into the details, here’s a quick overview: This stainless steel medical reactor uses advanced sheet metal manufacturing processes—CNC laser cutting, bending, TIG welding, and sanitary surface treatment—to create a corrosion-resistant, pressure-resistant vessel that is ideal for pharmaceutical and biotech processes. Its precision structure (±0.1 mm tolerance), seamless welds, and in-place cleaning compatibility meet the stringent hygiene and regulatory requirements of medical applications around the world.
This stainless steel medical reactor is designed for bioprocessing, including microbial fermentation and cell culture in pharmaceutical, biotech, and research institutions.
Made of high-grade SUS 316L or SUS 304 stainless steel, it can withstand corrosive media and repeated sterilization cycles.
Seamless TIG welded structure ensures leak-free operation under vacuum or positive pressure.
Key Features
1. Material grade: Made of 316L/304 stainless steel, it has excellent chemical resistance and biocompatibility.

2. Precision manufacturing: CNC laser cutting and bending, dimensional accuracy can reach ±0.1 mm.
Alloy Manufacturer in the U.S.

3. Weld Quality: Full penetration TIG welding by ASME certified welders eliminates cold laps and minimizes crevices.

4. Surface Finish: Internal electropolished to Ra ≤ 0.4 µm for Clean-in-Place (CIP) compliance; external No. 4 brushed finish for corrosion resistance.

5. Pressure Rating: Designed and tested to ASME Section VIII, Division 1 for maximum working pressure up to 2 bar (29 psi).

6. Hygienic Design: Internal welds ground flat; all ports and flanges meet 3A/BPE sanitary specifications.

7. Instrument Ready: Equipped with temperature probe, pressure gauge, sampling port, and CIP spray ball.
