Forged Fittings
What are Forged Fittings?
Forged fittings are pipe connectors manufactured through the hot forging process, where metal is shaped under high pressure to achieve exceptional strength, uniformity, and resistance to high-pressure applications. These fittings are designed for use in small-diameter, high-pressure piping systems and are commonly found in industries like oil & gas, petrochemical, power generation, and shipbuilding.
Available in various types such as elbows, tees, couplings, and unions, forged fittings are typically produced from carbon steel, stainless steel, and alloy steel, and conform to international pressure classes like Class 2000, 3000, and 6000.
Key Features
- High Pressure Performance – Ideal for critical fluid systems in harsh operating environments.
- Compact & Strong – Forged under extreme pressure for dense, grain-aligned structure and reduced risk of failure.
- Leak-Proof Connections – Available in threaded or socket weld configurations for robust sealing.
- Wide Material Options – Manufactured in carbon steel, stainless steel, alloy steel, and more.
- Standards Compliance – Produced to meet ASME, ASTM, MSS-SP, and other global quality benchmarks.

Do you have questions?
What is the advantage of forged fittings over cast fittings?
Forged fittings have a denser grain structure, making them stronger and more impact-resistant than cast fittings—especially under pressure.
Can I use forged fittings for underground or high-vibration applications?
Yes. Their compact structure and secure connections make them ideal for underground lines, vibration-prone systems, and mobile units.
What’s the difference between socket weld and threaded forged fittings?
Socket welds offer better sealing and strength, while threaded fittings are easier to install and dismantle. Choice depends on pressure class and maintenance access.
Are third-party inspections and certifications provided?
Absolutely. We provide Mill Test Certificates (MTCs) and TPI approvals (SGS, BV, TUV) as per customer requirements.
