Inconel Buttweld Fittings Manufacturer, Supplier & Exporter:

STAINLESS INDIA is a prominent manufacturer and worldwide exporter of Inconel Buttweld Fittings, providing high-performance pipe fittings in grades Inconel 600, 625, 601, 718, and Incoloy 800/800H/800HT.

We produce Inconel buttweld fittings in accordance with ASME B16.9, MSS-SP-43, ASTM B366, ANSI, DIN, and EN standards.

Our Inconel fittings offer outstanding performance in high-temperature, high-pressure, and highly corrosive environments, making them suitable for oil and gas, petrochemical, aerospace, chemical processing, and marine applications.

Inconel Buttweld Fittings are constructed from a nickel-chromium superalloy recognized for its unparalleled resistance to oxidation, carburization, pitting, crevice corrosion, and thermal fatigue. They provide leak-proof connections and long-lasting durability in extreme temperature conditions up to 1100°C.

These fittings require minimal maintenance, rendering them the preferred option for critical industrial pipelines.

All fittings are manufactured in compliance with ASME B16.9, MSS-SP-43, ASTM B366, and are supplied with EN 10204 3.1 / 3.2 test certificates and optional NACE MR0175 compliance.

Frequently Asked Questions – Inconel Buttweld Fittings

Inconel 625 exhibits superior resistance to corrosion and fatigue, particularly in seawater and harsh chemical environments, when compared to Inconel 600. While both are high-performance alloys, 625 is often the preferred choice for extreme marine and acid-processing applications.

These fittings are utilized in piping systems that operate under high temperatures and corrosive conditions, such as those found in refineries, gas turbines, chemical processing plants, boilers, and offshore oil & gas equipment.

Indeed, our Inconel buttweld fittings can be provided in full compliance with NACE MR0175 / ISO 15156 standards for sour service, ensuring safety and durability in environments containing hydrogen sulfide (H2S).

Inconel 600 and Inconel 625 are the most commonly used grades globally due to their versatile mechanical properties and high-temperature oxidation resistance.

Yes, we provide seamless Inconel fittings up to 24” NPS. For requirements beyond this size, we offer high-quality fabrication and welding options tailored to your specific project needs.

We provide EN 10204 3.1 / 3.2 certificates. Additionally, we offer comprehensive chemical analysis, mechanical property testing, radiography, and other NDT (Non-Destructive Testing) reports upon request.
