Precision Stainless Steel Tubing for Medical Device
In the medical device sector, stainless steel tubing is commonly used in applications such as hypodermic needles, catheter systems, surgical instruments, minimally invasive equipment, diagnostic devices, and laboratory instruments.
TORICH supplies high-precision stainless steel tubing for medical equipment-including seamless tubing, welded tubing, and precision capillary tubing-designed to meet stringent requirements for precision, cleanliness, and corrosion resistance.
Each pipe undergoes advanced processes, including cold drawing, cold rolling, bright annealing, precision straightening, and rigorous testing.
TORICH supplies precision stainless steel tubing for the medical device industry, featuring outer diameters ranging from 0.3 mm to 50 mm and wall thicknesses from 0.05 mm to 5 mm; lengths can be customized to meet specific requirements (standard lengths range from 2000 mm to 13000 mm).
We offer medical-grade stainless steel materials-such as 304/304L, 316/316L, 17-4PH, and Duplex 2205/2507-characterized by excellent corrosion resistance and biocompatibility.
TORICH's medical-grade stainless steel tubing is manufactured in compliance with major international standards, including ASTM A269, ASTM A213, ASTM A632, EN 10305, DIN, and JIS, and supports custom production based on client drawings and technical specifications.
