ASME B16.3 Malleable Iron Threaded Fittings: Class 150 and 300

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of ASME B16.3 testing. This Standard covers Class 150 and 300 malleable iron threaded fittings. It also includes provisions for the use of steel for covers and couplings in NPS 3/8 and smaller Class 150.

ASME B16.3 Malleable Iron Threaded Fittings: Class 150 and 300

This standard includes:

  • Pressure-temperature values;
  • Size and method of determining clearances of reducing fittings;
  • Marking;
  • Material;
  • Dimensions and tolerances;
  • Threading and veneers.

Class 150: This class represents fittings suitable for applications with relatively low pressure requirements. Class 150 fittings are commonly used in a variety of plumbing and industrial systems where pressure is relatively low.

Class 300: Class 300 fittings are designed for applications with higher pressure requirements and provide a higher pressure rating than Class 150 components. They are used in systems where high pressure conditions pose a problem.

The standard outlines the materials to be used for malleable iron threaded fittings and ensures that they meet the necessary material and chemical composition requirements to provide appropriate strength and performance.

Malleable iron threaded fittings are commonly used in plumbing systems, fire protection systems, industrial piping, and a variety of other applications. ASME B16.3 is important to manufacturers, engineers, and users of these fittings because it provides the necessary guidelines for the design, manufacture, and use of these components.
