forging flangeGrain refinement after repeated forging, The internal structure is uniform and dense, withstand voltage, anti-deformation, Improved fatigue resistance, Suitable for high pressure, continuous operation, Critical process piping.
cast flangePrecision investment casting process, complete molding, pore-free, No sand holes, Suitable for large caliber, special-shaped structure, Low pressure normal condition, It is an optimal scheme for engineering cost reduction.
Third, Gr2 / Gr5 material selection instructions
Grade 2 commercially pure titanium (UNS R50400)
Industrial general main titanium material, Excellent welding performance, high toughness, corrosion stability, seawater, salt mist, chloride, Weak acid-base medium has strong resistance, is the chemical, sea water desalination, Preferred material for low pressure piping in offshore engineering.
Grade 5 titanium alloy (UNS R56400 / Ti-6Al-4V)
high strength titanium alloy, Very high specific intensity, wear-resisting, shock resistance, Outstanding deformation resistance, High requirements for lightweight adaptation, load is large, Harsh durability offshore underwater equipment, aerospace, High-end equipment piping system.
4. Core product advantages
1. High installation fault tolerance and efficient construction
SO flat welding flange adopts sleeve structure, No need for butt welding flange high precision alignment, Direct casing can be positioned, Significantly reduce the difficulty of field installation, Suitable for high altitude, pipe gallery, Dense pipeline construction, Later disassembly and maintenance is more convenient.
2. Inside and outside welding, sealed firmly
Use in pipe, Double-sided welding technology of pipe exterior, Uniform joint stress, High weld strength, good sealing, Effectively eliminate medium microleakage, Ensure long-term stable operation.
3. Double process free selection, accurate control
The same specification supports forging, Double casting process selection, Forging for key parts of high pressure, Casting for low pressure general piping, No wasted performance, No additional costs, Adapt to various project budgets.
4. Full coverage of multiple sealing surfaces, strong versatility
Support RF salient, FF Full Plane, RTJ ring connection surface three mainstream sealing forms, Perfect for all types of valves, device interface, companion flange, Compatible with multinational standard piping systems.
