High Strength Forged Steel Flanges for Petrochemical Pipeline Connection and Pressure Control are manufactured through advanced open die and closed die forging techniques to ensure excellent toughness, durability, and leak-proof performance under high-pressure conditions. The flanges are available in carbon steel and alloy steel grades, offering superior resistance to corrosion, stress, and fatigue in demanding environments. With precise machining and strict dimensional inspection, each flange guarantees reliable sealing performance and long service life.
Key Features
Robust forged structure providing high tensile strength and impact resistance
Excellent pressure-bearing capacity and leak-proof connection design
Heat-treated for uniform mechanical properties and improved fatigue life
Available in multiple sizes and specifications tailored to project requirements
Applications
These forged steel flanges are widely used in petrochemical pipeline systems, refineries, power plants, and marine engineering projects. They are particularly suited for critical pressure control points, offshore platforms, and high-temperature fluid transmission, ensuring safety and efficiency in industrial operations.

| Product Name | High Strength Forged Steel Flanges for Petrochemical Pipeline Connection and Pressure Control |
| Material Grades | - Alloy steels (42CrMo4, 20CrMnMo, 18CrNiMo7-6) with superior strength and fatigue resistance - Carbon steels (Q235, 35#, 45#) for general-purpose flange connections - Stainless and duplex steels for enhanced corrosion resistance in aggressive media - Tailored material options available upon customer request |
| Forging Equipment | - Hydraulic Hammers: 5T, 8T, 12T - Open die forging presses up to 4,500T for large-diameter and heavy-duty flanges - Advanced heat treatment furnaces to ensure uniform hardness and toughness across the flange body |
| Manufacturing Process | Raw Material Verification → Cutting & Preheating → Open Die Forging & Shaping → Controlled Heat Treatment → Rough Machining & Beveling → Non-Destructive Testing (UT/MPI) → Finish Machining of sealing faces & bolt holes → Dimensional Inspection → Anti-corrosion Coating & Marking → Packaging → Delivery |
| Forging Ratio | ≥ 3.5 — Ensures refined grain structure, reliable pressure resistance, and extended service life under cyclic stress |
| Applications | - High-pressure pipeline flanges in petrochemical plants - Offshore oil and gas platforms for pipeline connection and sealing - Marine engineering systems handling corrosive seawater and high loads - Pressure control flanges in refineries and power generation facilities |
| Delivery Conditions | - Quenched and Tempered for high pressure and temperature resistance - Normalized, rough-machined, or fully finished condition available - Anti-rust oil coating or custom surface treatment based on customer needs |
| Testing & Inspection | - Spectrometry for chemical composition accuracy - Mechanical Tests: Tensile, Yield, Impact, Hardness - Non-Destructive Testing: Ultrasonic (UT), Magnetic Particle (MPI) to ensure defect-free performance - Dimensional and sealing face inspection with high-precision instruments |
Process Overview:
Raw material confirmation → Receiving and storage → Initial quality inspection → Preheating under controlled conditions → Forging and shaping → Thermal treatment for property enhancement → In-process inspection → Rough machining to specified dimensions → Non-destructive evaluation (UT/MT) → Comprehensive final quality check → Surface protection and marking → Packing and dispatch.
