Forged Flange is a high-strength pipeline connecting component manufactured by hot forging process. Compared with ordinary cast flanges, forged flanges feature dense internal structure, uniform grain distribution, no internal porosity or shrinkage defects. With excellent pressure resistance, impact resistance and sealing stability, forged flanges are widely used for high-pressure, high-temperature and heavy-duty pipeline connection in petroleum, chemical, power, pressure vessel and engineering machinery industries.
Core Advantages
Integral forging forming, continuous metal fiber structure, high fatigue resistance.
Dense internal texture, zero slag inclusion and zero porosity, high safety under high pressure.
High tensile strength and hardness, not easy to deform under heavy load.
Smooth machined sealing surface, excellent sealing performance.
Strict standard compliance: ANSI, DIN, JIS, GB standards available.
Custom size, material and heat treatment for special working conditions.
We supply full series of forged flanges, including Weld Neck Flange, Slip On Flange, Blind Flange, Threaded Flange, Socket Weld Flange, Lap Joint Flange, and large-diameter custom forged flange rings.
Carbon steel (A105, Q235, Q355, 45#), Alloy steel (4140, 42CrMo, 4340), Stainless steel (304, 316, 316L, 321). Special alloy materials can be customized.
Hot forging forming, rough machining, finish turning, drilling, tapping, shot blasting, rust prevention. Heat treatment such as normalizing, quenching and tempering is optional.
Forged flanges are widely used in oil & gas transmission, chemical pipeline systems, power plant equipment, high-pressure vessels, marine engineering, fire protection systems and industrial fluid piping systems.
All forged flanges are inspected by chemical composition analysis, mechanical property test, hardness test, dimensional inspection and ultrasonic nondestructive testing. Complete MTC certificates are provided, and third-party inspection such as SGS and BV is acceptable.
We provide OEM & ODM custom services for non-standard forged flanges. According to customer drawings, samples and working conditions, we can customize special sizes, materials, hardness and machining requirements.
High-quality standard and custom forged flanges with stable performance and competitive price. Welcome to send your drawings and requirements for free quotation.
