![]() ![]() Note also that there is often a 5 to 10 year lag between the approved ASTM edition and the approved ASME edition. Note that there may be minor exceptions in the SA version of ASTM standards, and the engineers, end users, purchasers and Manufacturer must comply. The details of this can be found in ASME Boiler and Pressure Vessel Code (BPVC) Section IIA, and is identified as SA106. Rather than “re-invent the wheel”, ASME has recognized the widespread use of this product, and has adopted the A106 standard for use in pressure vessel (BPVC) and pressure piping (B31.X) applications. In contrast with national codes (like API, ASME or CSA), ASTM A106 is rarely stipulated by national or state-level legal requirements. This ASTM specification is written so that the end user and the manufacturer can agree upon, and clearly understand, the properties and capabilities of the piping product being supplied. This means that you will never see ERW/HFIW or DSAW A106 pipes. Note that A106 allows only seamless pipe manufacturing techniques. It can be used upwards of 800F (427C), though the SA106 allowable stresses drop significantly above 400F (200C). ![]() Though the product is described as for “high temperatures”, ASME allows for use as low as -20F (-29C). ![]() When the steel pipes are to be joined together, it is presupposed that a welding procedure suitable to the grade of steel and intended use or service will be utilized.Ĭommon uses include pressure piping at high temperatures (piping for water, air or steam, etc.). Pipe ordered under this specification shall be suitable for bending, flanging, and similar forming operations, and for welding. It shall be permissible to furnish pipe having other dimensions provided such pipe complies with all other requirements of this specification. This specification covers seamless carbon steel pipe for high-temperature service in NPS 1/8 to NPS 48 inclusive, with nominal (average) wall thickness as given in ASME B 36.10M.
