Pipe, Tube, & Fittings
Atlantic Stainless supplies an extensive inventory of stainless steel pipe, tube, and fittings for structural, sanitary, and industrial applications. With a variety of grades, wall thicknesses, and finishes available, we can meet the demands of your project whether it requires strength, precision, or corrosion resistance.
We carry both welded and seamless stainless steel pipe and tubing, along with a complete line of butt-weld, threaded, and sanitary fittings. Our products are stocked in standard sizes and lengths, but we also offer custom cutting, polishing, and fabrication services to meet your exact requirements.
Stainless Steel Pipe vs. Tube: What’s the Difference?
Understanding the distinction between pipe and tube helps ensure you select the right material for your application:
Pipe is measured by nominal inside diameter (ID) and is typically used for conveying fluids or gases. It is often specified by schedule (wall thickness).
Tube is measured by outside diameter (OD) and wall thickness. It’s commonly used in structural, mechanical, or aesthetic applications where appearance and precision matter.
Common Applications
Our stainless steel pipe, tube, and fittings serve a wide range of industries and environments:
- Food & Beverage Processing
