Characteristic of Forged Elbow
Forged 90 ° elbow is a high-strength pipe fitting used to achieve a standard right angle turn in pipeline systems. Produced through integral forging technology, it ensures a dense material structure and excellent pressure bearing capacity, which can effectively withstand high-pressure fluids and pipeline stresses. Compared to other manufacturing methods, forged elbows provide a higher level of safety and reliability, and are essential core components for changing fluid direction in industrial pipelines, especially high-pressure and critical process pipelines.
Introduction to Fitting Pressure Ratings
The ASME B16.11 standard defines clear pressure ratings for forged fittings, with commonly used ratings for socket welded fittings being Class 3000, 6000, and 9000. Class 3000 belongs to the high-pressure category and is designed specifically for harsh industrial environments. It can be used in conjunction with thick walled pipelines to ensure the strength and sealing of connection points. Choosing Class 3000 fittings means choosing a reliable connection solution with high safety margins for your piping system.

304L Forged Fitting Application
Class 3000 F304L forged elbow is a widely used piping component. With its high pressure bearing capacity and excellent universal corrosion resistance of F304L material, it is widely used in process auxiliary pipelines and instrument pipelines in fields such as chemical, oil and gas, power, papermaking, and food industries. Whether transporting water, steam, compressed air, or various chemical media, it can provide an economical, reliable, and durable pipeline turning solution.
SMLSCO Factory Advantages
SMLSCO's forged pipe fittings are all produced in our own factory certified by NORSOK M650. The factory is equipped with 38 precision CNC lathes to ensure that the size, angle, and socket (or thread) of each elbow meet the strict tolerance requirements of ASME B16.11 standard. From raw material inspection, forging to final product testing, our control over the entire production process ensures that even commonly used materials such as F304L can maintain consistent high quality and reliability.
