Key Advantages
Bespoke Design Flexibility
Adapt to non-standard bolt patterns and irregular shapes without costly molds, ideal for retrofit or legacy systems. 3D modeling support (STEP/IGES files) for seamless integration.
High-Pressure Integrity
ASTM A105's forged structure ensures uniform grain flow, critical for high burst strength in oilfield operations.
Rapid Turnaround
Prototype to bulk production in 15-30 days (Small batches accepted).
Compliance & Safety
NACE MR0175 certification available for sour gas (H₂S) environments. 100% PT (Penetrant Testing) or UT (Ultrasonic Testing) to detect subsurface defects.
Applications
- Oil & Gas: Pipeline connectors, wellhead flanges, subsea equipment
- Refineries: High-temperature reactor flanges, valve manifolds
- Petrochemical: Acid-resistant flange joints, compressor systems
- Energy: Hydraulic power units, geothermal piping
Manufacturing Process
- Forging & Shaping: Hot forging ASTM A105 billets into near-net shapes
- Heat Treatment: Normalizing (900-950°C) to refine microstructure
- CNC Machining: 5-axis CNC milling for custom profiles and bolt holes
- Surface Finishing: Shot blasting + anti-corrosion coatings (optional)
- Quality Control: Dye penetrant (PT) / ultrasonic (UT) testing + 3D CMM
