| Product Name | Custom Machined Forged Steel Flanges for Marine Engineering Equipment and Offshore Platforms |
| Material Grades | - Alloy steels (42CrMo4, F51 duplex stainless steel, Inconel alloys) for high strength and corrosion resistance in seawater environments - Carbon steels (A105, 20#, 45#) for standard pressure piping systems - Tailored material options based on offshore engineering project specifications |
| Forging Equipment | - Hydraulic Hammers: 5T, 8T, 12T for flange preforms - Heavy-duty forging presses up to 4,500T ensuring precise fiber flow in large-diameter flanges - Specialized heat treatment furnaces designed to achieve optimal hardness and corrosion resistance |
| Manufacturing Process | Material Inspection → Cutting & Preheating → Open Die Forging → Heat Treatment → CNC Machining for Flange Faces & Bolt Holes → Non-Destructive Testing (UT/MT/PT) → Dimensional & Surface Accuracy Checks → Final Coating/Protection → Packing & Delivery |
| Forging Ratio | ≥ 3.0 — Provides improved structural density, crack resistance, and long-term durability under fluctuating offshore loads |
| Applications | - Subsea and offshore oil & gas pipeline connections - Flange systems for drilling rigs and FPSO units - Marine engineering equipment exposed to seawater pressure and vibration - Shipbuilding pipeline networks and high-load pressure vessels |
| Delivery Conditions | - Quenched and Tempered to ensure high tensile strength, impact resistance, and pressure retention - Delivered in CNC-machined, semi-finished, or rough-machined state depending on project needs |
| Testing & Inspection | - Spectrometry for chemical composition verification - Mechanical Testing: Tensile, Yield, Impact, Hardness - Non-Destructive Testing: UT, MT, PT for flaw detection - Precision measurement of sealing faces, bolt circle diameter, and surface finish to guarantee leak-proof performance |
Process Overview:
Material verification → Organized storage and handling → Preliminary inspection of dimensions and quality → Uniform heating with controlled parameters → Forging operation and forming → Heat treatment to achieve desired mechanical properties → Intermediate quality verification → Rough machining for structural accuracy → Non-destructive testing (UT/MT) → Final inspection and approval → Surface finishing with protective coating and identification marking → Secure packaging and shipment to customer.
