SS Seamless Tube can be produced with heavier wall thicknesses for mechanical applications. Permissible Variations in Outside Diameter.

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 readings in any one cross-section. It is less expensive than seamless or welded-and-drawn tubing.

Tensile Strength min ksi MPa. Ksi MPaMin.

The above tolerances on outside diameter include ovality except for thin-wall pipe. The steel shall conform to the chemical composition requirements. It is extremely ductile, with excellent strength at elevated temperatures.

Different mechanical test requirements that includes, flaring test, flange test, hardness test, and reverse toleracne test are presented. Tubes not heat-treated to be stencilled: It is extremely ductile, with excellent strength at elevated temperatures.

Upon completion, all material shall:. ASTM A Seamless Tubes are manufactured using supreme grade alloying elements, thus ensuring hardness and chemical resistance.

Thin-wall pipe is defined as having a wall thickness of 3 percent or less of the outside diameter. Also, each astm a tube shall be subjected to the non-destructive electric test or the hydrostatic test.

Yield Strength min ksi MPa. Thin-wall pipe atsm develops significant ovality out-of-roundness during final annealing, straightening, or both.

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 demanding applications. However, for thin-wall pipe the difference in extreme outside diameter readings ovality in any one cross-section shall not exceed 1.

Permissible Variations in Wall Thickness Tplerance and welded no filler metal added. Cut Length bIn. The 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 ideal for hydraulic and instrumentation tubing in chemical, textile, and pulp and paper industries, and in marine environments.

Finally the hardness requirements for different grades of astm a tubes are highlighted. We stocks a wide range of industry standard sizes of both welded and seamless stainless steel tubes in astm a The minimum wall thickness at any point shall not be more than To compute safe working pressures, above burst pressures should be divided by your desired safety factor.
