Trusted Exporter of ASTM A694 F52/F60/F65/F70 Flanges & Forged Fittings – Sizes from ½” to 48” – ANSI/ASME B16.5, B16.47 & MSS SP-44 – Pressure Ratings 150# to 2500# – Supplied with EN 10204 3.1 / 3.2 Certification.
ASTM A694 F42/F46/F52/F60/F65/F70 are high-strength carbon steel grades specifically developed for high-pressure transmission service. These grades are widely used in the oil, gas, petrochemical, and power generation industries where durability and resistance to mechanical stress are critical. Manufactured using controlled forging and heat treatment processes, ASTM A694 flanges ensure structural reliability and performance under extreme service conditions. These flanges are ideal for use in systems that demand superior strength, toughness, and resistance to sour gas environments.
We offer a comprehensive range of ASTM A694 high-yield carbon steel flanges including Weld Neck (WNRF), Slip-On (SORF), Blind (BLRF), Socket Weld (SWRF), Threaded, Lap Joint, and Ring Type Joint (RTJ) flanges. These flanges are manufactured in accordance with ASME B16.5, ASME B16.47 Series A/B, and MSS SP-44 standards, available in pressure classes from 150# to 2500#, and sizes ranging from ½” to 48” NB. They undergo strict quality checks including ultrasonic testing, radiographic inspection, PMI, and hydrostatic tests, with material traceability provided as per EN 10204 3.1 / 3.2 certifications.
ASTM A694 F42 to F70 flanges are engineered for high-pressure systems such as cross-country pipelines, refineries, offshore drilling rigs, and process piping. Their high tensile and yield strength make them suitable for critical applications involving elevated temperatures and pressures. The F65 and F70 variants, in particular, are favored for their exceptional yield strength in sour gas service, conforming to NACE MR0175/ISO 15156 standards. These flanges offer long service life, dimensional stability, and leak-proof performance, making them a reliable solution for demanding environments.
As an ISO 9001:2015 certified supplier, we ensure consistent quality and traceability across all ASTM A694 flanges. Our stock includes products compliant with NACE, PED, IBR, and customer-specific quality plans. With manufacturing and sourcing capabilities across India, South Korea, Japan, Germany, and the USA, we support bulk and project-based deliveries worldwide. Whether you need urgent stock supply or custom-made flanges, our global logistics network ensures on-time delivery to the USA, UAE, Saudi Arabia, Qatar, Europe, South Africa, and Southeast Asia.
