SS Seamless Tube can be produced with heavier wall thicknesses for mechanical applications. Permissible Variations in Wall Thickness Seamless and welded no filler metal added.

We stocks a wide range of industry standard sizes of both welded and seamless stainless steel tubes in astm a Tubes not heat-treated to be stencilled: ASTM A Seamless Tubes are manufactured 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- toledance high-temperature service.

ASTM A & ASTM A – Chicago Tube & Iron

Thin-wall pipe is defined as having a wall thickness of 3 percent or less of the outside diameter. Tensile Strength min ksi MPa. 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 less expensive than seamless or welded-and-drawn tubing.

It is extremely ductile, with excellent strength at elevated temperatures. Also, each astm a tube shall be subjected to the non-destructive electric test or the hydrostatic test.

Ovality 2 x Tol. To compute safe working pressures, above burst pressures should be divided by your desired safety factor. Finally the hardness requirements for different grades of astm a tubes are highlighted.

Cut Length bIn. Yield Strength min ksi MPa.

ASTM A269 & ASTM A312

Thin-wall pipe usually develops significant ovality out-of-roundness during final annealing, straightening, or both. It is ideal for hydraulic and instrumentation tubing in chemical, textile, and pulp and paper industries, and in marine environments. However, for thin-wall pipe the difference in extreme outside diameter readings ovality tllerance any one cross-section shall not exceed 1. ASTM A Stainless steel tubes are finished in accordance with customer needs regarding dimensional and toperance thickness specifications as well as heat treatment for more demanding applications.

ASTM Specification & Tolerance For Tubing & Piping

The above tolerances on outside diameter include ovality except for thin-wall pipe. Upon completion, all material shall:. The steel shall conform to the chemical composition requirements.

The minimum wall thickness at any point shall not be more than It is extremely ductile, with excellent strength at elevated temperatures. Different mechanical test requirements that includes, flaring test, flange test, hardness test, and reverse tplerance test are presented.

ASTM Specification & Tolerance For Tubing & Piping

Ksi MPaMin. 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.
