ASME B16.4 Gray Iron Threaded Fittings Grade 125 and 250

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of ASME B16.4 testing. This Standard for gray iron threaded fittings, Classes 125 and 250, covers:

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

Class 125: This class represents fittings suitable for applications with relatively low pressure requirements. Class 125 fittings are commonly used in plumbing and industrial systems where pressure is relatively low.

Class 250: Class 250 fittings are designed for applications with higher pressure requirements and provide a higher pressure rating than Class 125 components. They are used in systems where high pressure conditions pose a problem.

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

Gray iron threaded fittings are commonly used in plumbing systems, fire protection systems, industrial piping, and a variety of other applications. ASME B16.4 is important to manufacturers, engineers, and users of these fittings because it provides necessary guidelines for the design, manufacture, and use of these components.
