The steel shall conform to the chemical composition requirements.

The minimum wall thickness at any point shall not be more than SS Seamless Tube can be produced with heavier wall thicknesses for mechanical applications. Tensile Strength min ksi MPa. Different mechanical test requirements that includes, flaring test, flange test, hardness test, and reverse flattening test are presented.

The ASTM A specification covers nominal-wall-thickness, seamless and welded austenitic steel tubing for general corrosion-resisting and low- or high-temperature service.

ASTM A269 / A269M Stainless Steel Seamless Tubes

A Stainless Steel Tubes Coating. 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. 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.

Ovality 2 x Tol.

Specification Tolerances for ASTM A

The above tolerances on outside diameter include ovality except for thin-wall pipe. Thin-wall pipe tolreance defined as having a wall thickness of 3 percent or less of the outside diameter.

Thin-wall pipe usually develops significant ovality out-of-roundness during final annealing, straightening, or both. The above diameter tolerances are tolerahce 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.

ASTM Specification & Tolerance For Tubing & Piping

To compute safe working pressures, above burst pressures should be divided by your desired safety factor. It tolerznce less expensive than seamless or welded-and-drawn tubing.

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