ASME / ANSI flanges (ASME - American Society of Mechanical Engineers, American National Standards Institute) large diameters from 26 to 60 inches are manufactured according to ASME / ANSI B16.47 "Large Diameter Steel Flange ".
These standards describe the modes of temperature and pressure, materials, dimensions, tolerances, markings, etc. In accordance with the specified standards, according to the nominal pressure, the flanges are divided into classes (Class, allowable nominal pressure in psi): 150, 300, 400, 600, 900, 1500, and 2500. To convert from units of "class" to kgf / cm², it is necessary to divide the value of "class" by 6. Also, this standard includes recommendations and requirements for flange connections, namely, flange fasteners, and gaskets for flanges.
The ring billet factory produces steel butt weld flanges according to ASME B16.47 with Welding Neck execution.
To adapt the use of imported pipeline fittings to Russian pipes made according to GOST, in the face of increased demand, the Ring Billet Plant develops and manufactures steel flanges, in which the sealing surface is made according to ASME, DIN or EN standards (like ASME flanges, DIN flanges or flanges EN, respectively), and the welded part - for a domestic pipe (like a butt-welded collar flange in accordance with GOST 33259-2015).
Flanges are tested for tensile strength, yield strength and impact strength, and mechanical properties are determined. The products comply with the requirements of the technical regulations of the Customs Union of the EAEU TR CU 032/2013, supplied with quality certificates.
The warranty period for flanges is 24 months.
It is possible to buy or find out the price for inch and metric ASME / ANSI B16.47 flanges at the Ring Billet Plant.
