5. Detailed Description
Production Process:
- Forging: Close-die forging for seamless equal crosses (up to 48").
- Hot Bending: Induction bending for large-diameter welded equal crosses.
- Finishing: Automatic polishing machines (Ra ≤ 0.8μm for sanitary grades).
- Inspection: 3D coordinate measuring machine (CMM) for branch angle/offset accuracy.
Advantages:
- Low Friction Loss: Smooth internal bore reduces turbulence (Roughness ≤ 3.2μm).
- Anti-Corrosion Coating: Optional epoxy/FBE lining for harsh media (pH 0-14).
- Interchangeability: 100% compatible with global pipe standards (ANSI/ASME/DIN).
6. Customization & Packaging
- Custom Services:
- Special angles (lateral equal crosses, custom branch offsets).
- Cladded materials (e.g., stainless steel + carbon steel).
