Frequently Asked Questions
What is an SS 316 thin-wall tube?
It is a cold-drawn stainless steel tube made to ASTM A269 in grade UNS S31600, built with a wall thickness-to-outer-diameter ratio of under about six percent. The thin wall keeps weight low while the molybdenum in grade 316 gives strong resistance to chlorides and pitting.
What is the wall thickness range of SS 316 thin-walled tubes?
Our standard range runs from about 0.15 mm up to 3.00 mm wall thickness, across outer diameters from around 1 mm up to 168 mm. Smaller and larger combinations are available on request.
What is the difference between a thin-wall and a standard-wall SS 316 tube?
The thin-wall tube has a wall-to-outer-diameter ratio of about six percent, giving lower weight but a lower pressure rating for the same size. A standard wall tube carries a heavier wall for the same outer diameter, giving higher pressure capability and more tolerance for rough handling during fabrication.
What sizes are available for SS 316 thin-wall tubing?
We stock outer diameters from around 1 mm up to 168 mm, with wall thicknesses from about 0.15 mm to 3.00 mm, in precision-cut lengths from 1 mm up to 6000 mm depending on requirement.
Can SS 316 thin-wall tubes be used in marine and offshore environments?
Yes. The molybdenum content in grade 316 gives it strong resistance to chlorides from seawater and salt-laden air, which is exactly the duty most marine and offshore instrumentation and process tubing is asked to handle.
Which industries commonly use SS 316 thin-wall tubes?
Instrumentation and control systems, heat exchanger tubing, medical and surgical equipment, pharmaceutical processing, food and beverage processing, chemical processing and transfer lines, marine and offshore installations, and laboratory and analytical instruments all rely on SS 316 thin-wall tubes.
