The steel shall conform to the chemical composition requirements. Cut Length bIn.

Different mechanical test requirements that includes, flaring test, flange test, hardness test, and reverse flattening test are presented. SS Seamless Tube can be produced with heavier wall thicknesses for mechanical applications.

The minimum wall thickness at any point shall not be more than Tensile Awtm min ksi MPa. ASTM A Stainless steel tubes are finished in accordance with customer needs regarding dimensional and wall thickness specifications as well as heat treatment for more tolerahce applications. We stocks a wide range of industry standard sizes of both welded and seamless stainless steel tubes in astm a Also, each astm a tube shall be subjected to the non-destructive electric test or the hydrostatic test.


Permissible Variations in Outside Diameter. It is less expensive than seamless or welded-and-drawn tubing.

Thin-wall pipe is defined as having a wall thickness of 3 percent or less of the outside diameter. However, for thin-wall pipe the difference in extreme outside diameter readings ovality in any one cross-section shall not exceed 1. It is ideal for hydraulic and instrumentation tubing in chemical, textile, and pulp and paper industries, and in marine environments.

Tubes not heat-treated to be stencilled: Upon completion, all material shall:. ASTM A Seamless Tubes are a2269 using supreme grade alloying elements, thus ensuring hardness and chemical resistance. A Stainless Steel Tubes Coating. Our offered ASTM A Specification covers nominal-wall-thickness, seamless and welded austenitic steel tubing for general corrosion-resisting and low- or high-temperature service.

It is extremely ductile, with excellent strength at elevated temperatures.

ASTM A269 & ASTM A312

To compute safe working pressures, above burst pressures should be divided by your desired safety factor. Ovality 2 x Tol. It is extremely ductile, with excellent strength at elevated temperatures.


The above diameter tolerances are not sufficient to provide for additional ovality except in thin-wall pipe and are applicable only to the mean of the extreme maximum and minimum outside diameter toleraance in any one cross-section.

ASTM Specification & Tolerance For Tubing & Piping

Permissible Variations in Wall Thickness Seamless and welded no filler metal added. Thin-wall pipe usually develops significant ovality out-of-roundness during final annealing, straightening, or both. Ksi MPaMin. Tlerance the hardness requirements for different grades of astm a tubes are highlighted.

The above tolerances on outside diameter include ovality except for thin-wall pipe.
