NXF UNS NO7718/2.4668/NiCr19NbMo/alloy 718 DN15-1200 Class150-2500 Nickel Alloy Forged Fitting Lap Joint Flanges
Alloy 718 Introduction.
Lap Joint Flanges Introduction
4. Application Scenarios and Applicable Working Conditions：
This type of flange is mainly applicable to low-pressure and normal-temperature piping systems with corrosive media. It is widely used in chemical industry, food and pharmaceutical, water treatment, seawater desalination and light industry fields. It is especially suitable for precious metal pipelines such as stainless steel, titanium alloy and Monel alloy, as well as pipeline nodes that require frequent disassembly, inspection and maintenance. However, it is not suitable for working conditions with high temperature, high pressure, strong impact load and severe pipeline vibration.

718 Lap Joint Flanges Produce Processing
1. Raw Material Cutting and Inspection：Select qualified raw steel materials and cut them into blank pieces according to standard sizes. Conduct incoming inspection to check material composition, hardness and surface quality to ensure compliance with flange manufacturing standards.
2. Hot Forging Forming：Heat the flange blanks to the required temperature and complete hot forging and ring rolling. This process improves metal density, enhances mechanical strength, and forms the basic outer shape of lap joint flanges.
3. Heat Treatment：Perform annealing or normalizing treatment on forged flanges. It removes internal forging stress, improves material toughness, and prevents deformation and cracking during subsequent processing and usage.
4. Precision Machining：Use CNC machines to precisely machine the inner hole, outer diameter, thickness, lap surface and bolt holes. All dimensions are strictly controlled within standard tolerance to ensure accurate assembly.
5. Deburring and Surface Finishing:Remove all burrs, sharp edges and machining residues. Polish the lap sealing surface to keep it smooth and flat, ensuring good sealing performance during pipeline connection.
6. Final Inspection and Packaging:Inspect the finished flanges for dimension accuracy, surface defects and flatness. Qualified products are marked, cleaned and packaged ready for delivery.
