pressure control forged steel flanges

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.

Item Details
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
