Precision Metal Tubing
Custom Tubing Solutions for Advanced Medical Devices
At Viant, we go beyond dimensions and alloys. Our precision tubing solutions are designed to meet your device’s unique performance requirements through a collaborative approach that integrates specification, precision processes, and rigorous characterization.
Engineered for Reliability: Our Integrated Approach
Our tubing solutions are designed to meet your device’s unique performance requirements through a collaborative approach that integrates specification, precision processes, and rigorous characterization—empowering MedTech OEMs and emerging innovators to bring life-changing devices to market with confidence.
Collaborative Engineer-to-Engineer Development
Working from your application requirements, we develop comprehensive specifications including engineering blueprints, CAD drawings, and customer specifications. We ensure compliance with industry standards (ISO, ASTM) while defining precise tolerance requirements, surface finish specifications, and mechanical property targets.
Welded, Seamless & Surface-Treated Solutions
Our advanced manufacturing capabilities include both welded and seamless drawn tubing, with specialized surface treatments and robust cleaning protocols. Advanced tube sinking and drawing over mandrel techniques ensure consistency and precision at every stage.
Dimensional, Metallurgical & Performance Testing
Every tube undergoes comprehensive testing including dimensional inspection (OD, ID, wall thickness), metallurgical analysis, and mechanical testing (tensile, fatigue). We conduct microscopic evaluation, surface roughness measurement, and corrosion resistance testing, providing complete certification and documentation to meet regulatory validation requirements (ISO 13485, FDA).
medical tubing Expertise drawn from decades of experience
Dating back to our founding as Uniform Tubes in 1940, we have over 80 years of precision tube manufacturing. In 1999, we extended our tube-drawing skills to include nitinol. We now produce nitinol tubes at commercial scale for medical device manufacturers worldwide.
ENGINEERED NITINOL TUBING FOR MEDICAL APPLICATIONS
Drawn for Durability. Delivered with Confidence.
Nitinol can be a challenging material to work with—especially when fatigue life, tight tolerances and consistent properties are critical. At Viant, we support OEMs with reliable nitinol tubing drawn to meet the mechanical, dimensional, and performance standards required in regulated medical devices.
With decades of experience in precision tube drawing, we manufacture nitinol tubing for diverse clinical applications, from stent delivery systems to orthopedic devices. Our team works closely with yours to define requirements, troubleshoot constraints, and deliver tubing that aligns with your design intent—whether for prototyping or high-volume production.
