Product Overview and Technical Details

The shipment includes three main categories of pipeline components:

1️⃣ ASTM A105 Weld Neck Flanges (RF)

  • 6″ – Class 150, SCH40
  • 2″ – Class 150, SCH XS
  • Standard Sealing Face: Raised Face (RF)
  • Material: ASTM A105

These Class 150 RF weld neck flanges are designed for strength, pressure stability, and smooth stress distribution in critical piping connections.

2️⃣ SS316 Spiral Wound Gaskets (With Inner & Outer Ring)

  • 6″ – 4.5mm Thickness, Class 150
  • 2″ – 4.5mm Thickness, Class 150
  • Material: Stainless Steel 316 (Inner Ring & Outer Ring)
  • Sealing Type: RF

The SS316 spiral wound gasket with inner and outer ring provides enhanced sealing reliability, especially for raised face flange connections operating under fluctuating pressure and temperature conditions.

3️⃣ ASTM A516 Gr.70 Spectacle Blind Flange (RF)

  • 6″ – Class 150
  • Sealing Face: RF
  • Material: ASTM A516 Grade 70

The 6 inch Class 150 spectacle blind flange allows safe line isolation and quick switching between open and closed positions, widely used in oil, gas, and industrial facilities.

Why This Combination Matters

For pipeline systems, compatibility between flanges, gaskets, and isolation components is essential. This project combines:

  • ASTM A105 weld neck flange Class 150 RF
  • SS316 spiral wound gasket 4.5mm with inner outer ring
  • ASTM A516 Gr.70 spectacle blind RF flange

Together, they ensure:

  • Secure sealing performance
  • Reliable mechanical strength
  • Safe pipeline isolation capability
  • Long service life in industrial environments

This type of integrated supply simplifies procurement and ensures dimensional compatibility across components.

Quality Control and Inspection

All products supplied by Haihao Group undergo:

  • Dimensional inspection
  • Material verification
  • Surface finish inspection
  • Gasket structure examination
  • Marking and traceability confirmation

The flanges and spectacle blind are manufactured according to international standards, ensuring compatibility with Class 150 RF flange systems.
