Product Description
Forged fitting SW Socket welding 90D elbow
Imagine a pipe system where critical, high-temperature fluids or steam flow through a small-bore network, and the slightest leak or weak joint could cost thousands or shut down operations. That’s where our Forged A182 F11 Socket Elbow shines: a rugged, ergonomically designed fitting crafted from chromium-moly alloy steel, built to endure extreme pressures and temperatures, yet precise enough to ensure leak-free joints at every turn.
Forged through high-pressure shaping and then normalized and tempered, this elbow is not only strong — it's resilient. When you touch it, the smooth, slightly warm surface betrays its heat-treated heritage. Its socket weld geometry allows the pipe to seat deeply, offering strong structural integrity with fillet welds that deliver high-pressure sealing without compromising toughness.

Special design available as the requirement of customer | ||
Our socket elbows are forged under rigorous conditions, producing a densely structured, high-strength component. After forging:
Normalizing (heating to specified temperature, controlled cooling) to relieve internal stresses and refine grain structure.
Tempering to balance hardness and toughness, ensuring the fitting won’t crack under repeated thermal cycles.
This process yields a robust elbow with excellent microstructural stability, delivering reliability in demanding environments.
We ensure product integrity through a comprehensive quality control program:
Chemical composition analysis (spectro analysis / PMI) to verify the F11 alloy chemistry
Mechanical testing: tensile, yield, elongation
Hardness testing to ensure the right balance of strength and ductility
Macro & microstructure inspection to verify grain flow and detect any forging defects
Non-destructive testing: radiographic (RT) or ultrasonic (UT) testing, depending on customer requirement
Third-party inspection available upon request
Certifications / Mill Test Certificate (e.g., EN 10204 3.1 or other as required)
These rigorous checks help ensure durability, safety, and traceability, aligning with B2B buyers’ expectations for critical applications.
The Forged A182 F11 Socket Elbow is ideal for:
High-pressure steam lines in power generation plants
Petrochemical and refinery piping systems
Oil & gas operations (onshore / offshore)
High-temperature service (e.g., heat exchangers, boilers)
Chemical processing units with elevated temperature and cyclic loads
Maintenance-intensive systems where reliable joints reduce downtime
Its combination of strength, corrosion resistance, and fatigue tolerance make it especially valuable in sectors where failure is not an option.
High strength & toughness: Thanks to Cr-Mo alloy and heat treatment, this fitting can sustain high tensile and yield demands.
Leak-tight joints: Socket-weld design provides deep insertion and strong fillet welds, minimizing leak risk.
Thermal resilience: Stable in high-temperature and cyclic environments; resists creep and deformation.
Corrosion resistance: Chromium and molybdenum content provide increased resistance to oxidation and pitting compared to plain carbon steel.
Dimensional precision: Forged manufacturing ensures accurate, consistent dimensions for proper alignment and reduced rework.
Customizable pressure rating: Available in various classes (2000–9000#) to match your system requirements.
Expertise & Authority: With deep experience in alloy steel fittings and strict adherence to ASTM/ASME standards, we deliver products you can trust.
Reliability: Each elbow undergoes full traceability, from raw material heat number to final inspection.
Quality-first mindset: We perform rigorous testing (chemical, mechanical, NDT) and accept third-party inspection.
Flexible supply: Supporting small to large volume orders, with fast turnaround and packaging optimized for export.
Technical support: We offer engineering support, cross-referencing, and assistance to help you choose the right part for your system.
Q1: What is the advantage of F11 alloy versus regular carbon steel?
A1: F11 (1.25Cr–0.5Mo) alloy provides significantly better high-temperature strength, creep resistance, and corrosion resistance than plain carbon steel. It’s ideal for high-pressure, high-temperature systems where longevity and safety are critical.
Q2: Can this elbow be welded with standard welding procedures?
A2: Yes. The socket-weld design is well-suited for fillet welding, and the alloy’s weldability is good when proper preheat and post-weld heat treatment practices are followed.
Q3: What inspection certificates do you provide?
A3: We typically provide Mill Test Certificates (e.g., EN 10204 3.1) and can arrange third-party inspection (e.g., radiography, PMI) based on your project requirements.
Q4: Do you offer custom pressure classes or sizes?
A4: Yes, we can produce elbows in various classes (2000–9000#) and sizes (within standard ranges), and we also accommodate custom orders per your engineering specs.
Q5: How is the product packaged and shipped?
A5: We pack fittings in export-grade wooden crates or pallets, ensuring protection during transit. Marking includes grade, standard, class, size, and heat number for traceability.
