ASTM Standards for Material Composition of Needle Valves | Perfect Engineers

What is ASME B16.34?

Assured Quality. Global Compliance. Traceable Materials.

At Perfect Engineers, every needle valve is manufactured from raw materials that fully comply with the relevant ASTM (American Society for Testing and Materials) standards. These standards define the chemical composition, mechanical properties, and manufacturing criteria for metals used in pressure-retaining components.

Our valves meet global procurement requirements for industries such as oil & gas, chemical, petrochemical, pharmaceuticals, and power generation.

What Are ASTM Material Standards?

ASTM standards specify:

Chemical composition limits (C, Cr, Ni, Mo, etc.)
Mechanical properties (tensile strength, hardness, elongation)
Manufacturing conditions (heat treatment, forging, etc.)
Marking, testing, and certification guidelines

These are essential for:

Pressure-retaining valve bodies and bonnets
Corrosion resistance in aggressive media

Compatibility with ASME B16.34, API 598, and CE/IBR projects

FAQs – ASTM Material Standards for Needle Valves

Do all Perfect Engineers valves follow ASTM material standards

Yes. All our valves are manufactured from ASTM-compliant forged or barstock raw materials with heat number traceability.

Do you supply EN/ASTM dual-compliant materials?

Yes. Many grades like SS 316, Monel, Duplex are supplied with dual EN + ASTM compliance.

Are your valves compatible with CE/IBR/API requirements?

Absolutely. ASTM-grade valves are accepted globally under CE/IBR/API certifications.

Can we request custom material tests (spectro, PMI)?

Yes. We offer spectro analysis, PMI testing, and TPI witnessing on request.
