When it comes to stainless steel tube sizes, Arham Alloys offers one of the widest selections in India. From precise stainless steel tubing dimensions to compatible stainless steel tube fittings dimensions, and a comprehensive stainless steel tubing size chart, this guide covers everything you need.
Expect to see stainless steel tube sizes referenced throughout—ensuring clarity for your procurement and design teams.
What are Stainless Steel Tube Sizes?
Stainless steel tube sizes refer to the actual outer diameter (OD), wall thickness (WT), and length of the tubing. Unlike piping, which follows nominal sizing (NPS), tubing is defined by precise OD × WT specifications. These are critical for high-precision applications in industries like pharmaceuticals, food & beverage, petrochemicals, and instrumentation systems.
Stainless Steel Tube Dimensions at Arham Alloys
Arham Alloys provides stainless steel tubing with the following actual size dimensions:
- Outer Diameters (OD): From 3.18 mm (1/8″) to 304.8 mm (12″)
- Wall Thicknesses (WT): From 0.5 mm to 12.7 mm (depending on OD)
- Lengths: Standard 6 meters, with custom cut-to-size options available
These stainless steel tube sizes are standardized and easy to reference using the OD × WT stainless steel tubing size chart below.
Stainless Steel Tube Fittings Dimensions
To ensure leak-free and pressure-stable connections, the stainless steel tube fittings dimensions must match the tubing specifications:
- OD Tolerances: Typically +0.15 mm / −0.08 mm
- Fittings Compatibility: Elbows, tees, reducers, and couplings fabricated to match OD × WT dimensions
- Welding and Threading: Supported for seamless integration
All fittings are certified per ASTM and ASME standards and designed for full dimensional compatibility.
