ASTM A333 Low Temperature Pipe

EO Flanges is a well-known factory of ASTM A333 Low Temperature Pipe, which has soaring tensile potency. ASTM A333 Low Temperature Pipes are quality accepted on distinct industry standards by the capable quality specialists.

  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. In contrast with national codes (like API, ASME or CSA), ASTM A333 is rarely stipulated by national or state-level legal requirements.

There are several grades in A333, each with different steelmaking approach to improve the steel’s impact properties at lower temperatures. Several grades have nickel (Ni) additions, and are capable of high toughness at cryogenic temperatures as low as -320F (-195C). Many of these grades would be considered rare, and in the experience of Bri-Steel, they are expensive to procure and may be difficult to find a capable fabricator with an proven weld procedure. The exception to this is Gr6, which is quite common and is regularly stocked in colder regions of North America. A333 Gr6 has proven impact toughness at -50F (-45C), and is commonly used in applications where the piping is exposed directly to cold environments during construction and/or in operation.

A333 Gr6 is also commonly used for pressure piping of compressed gas, where a crack would be expected to have catastrophic consequences.

Rather than “re-invent the wheel”, ASME has recognized the widespread use of this product, and has adopted the A333 standard for use in pressure vessel (BPVC) and pressure piping (B31.X) applications. The details of this can be found in ASME Boiler and Pressure Vessel Code (BPVC) Section IIA, and is identified as SA333. Note that there may be minor exceptions in the SA version of ASTM standards, and the engineers, end users, purchasers and Manufacturer must comply. Note also that there is often a 5 to 10 year lag between the approved ASTM edition and the approved ASME edition. This means that there can be minor differences between the two specifications. Most engineers who spec SA333 product will also prefer to follow the requirements of the more recent ASTM version (which is usually also more strict), resulting in the common notation ASTM/ASME A/SA106 on the product documentation.

There is a lower limit on manganese (Mn) in ASTM A333 Gr6 of around 0.30% Mn, though you will typically see around three times this much (around 0.90% Mn). For products that are hot rolled, it will be more common to see values of above 1.20% Mn, as the increased alloying is necessary to attain the impact toughness requirements of the standard. Because of these considerations, this product will commonly have a Mn/C ratio of 4 to 8 depending on the production method. Therefore, ASME B31.3 limits the low temp application of SA333 Grade 6 products to above -50F (-45C).
