Sanitary Tubing

Our polished stainless steel Sanitary Tubing is manufactured in accordance with ASTM A270 and 3-A sanitary standards. All Sanitary Tubing is made from cold rolled stainless steel strip with chemical elements specially controlled to enhance weldability. The weld bead is cold-worked to a full finished condition, resulting in a virtually undetectable longitudinal weld. Bright annealing to 1,900°F minimum follows in a controlled atmosphere to preserve maximum structural integrity. The tubes are then mechanically polished to a 180 grit (20 μ-in. Ra maximum) interior and 150 grit (32 μ-in. Ra maximum) exterior finish. Tubes are then line-stenciled with OD, wall, ASTM specifications, grade, and heat number.

Sanitary Tubing is required in the food and beverage industry for hygienic processing. Unlike standard ASTM A269 welded and seamless tubing, which comes in mill finish with a courser inside diameter (ID), the ID of Sanitary Tubing is polished to prevent impurities from settling and causing corruption.

James Duva, Inc. stocks Sanitary Tubing in 304L and 316L, from ½” to 12” OD. Our tubing is available in single lengths or in box quantities, and is manufactured by mills with the highest quality standards.
