TOP REMINDER OF ASTM A213 TP316 Stainless Steel Tube Pipe Wall Thickness Tolerance
General Tolerance
The wall thickness tolerance for ASTM A213 tp 316 seamless stainless steel tubing / tube is defined as -0% (minimum) to +20% (maximum) of the nominal thickness. This ensures the actual wall thickness never falls below the specified value but may exceed it by up to 20%.
TP316 Stainless Steel tube Key Specifications
Nominal Thickness Compliance:
The tube must meet the standard’s minimum wall thickness requirement without deviation below the nominal value.
Excess material (up to +20%) is permitted to accommodate manufacturing variability.
Critical Applications:
Strict adherence to the tolerance range ensures reliability in high-pressure and high-temperature environments, such as boilers and heat exchangers.
TP316 Stainless Steel Tube Example Calculation
| Nominal Thickness (mm) | Minimum Allowed (mm) | Maximum Allowed (mm) |
| 2.0 | 2.0 | 2.4 (+20%) |
| 5.0 | 5.0 | 6.0 (+20%) |
Summary
ASTM A213 TP 316 stainless steel tube / tubing mandates a -0/+20% tolerance for seamless tubing wall thickness. This balances manufacturing feasibility with performance integrity in critical industrial applications.
FAQ
Q1: Why is there no negative tolerance for wall thickness?
A: A minimum thickness guarantee ensures structural safety under pressure.
Q2: Does the +20% tolerance apply to all tubing sizes?
A: Yes, unless otherwise specified in supplementary standards (e.g., ASME).
Q3: How is compliance verified?
A: Manufacturers use ultrasonic or eddy-current testing to validate thickness

TP316L STAINLESS STEEL SEAMLESS PIPE is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids.
It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.
TP316L SMLS pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable.
Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.
