Flanges and Gaskets Supplied to Singapore for High-Pressure Piping Systems

Haihao Group has successfully completed the delivery of a batch of flanges and industrial gaskets for a customer in Singapore. The shipment includes ring joint gaskets (RTJ), spiral wound gaskets, RTJ blind flanges, and RF blind flanges, designed for both standard ASME flange connections and high-pressure API 6A applications.

All products were manufactured in strict accordance with international standards and customer-specified pressure ratings, ensuring safe and reliable sealing performance in demanding operating conditions.

ASME B16.20 SS316 Spiral Wound Gaskets

Ring Joint Gaskets for API 6A and ASME Applications

The supplied octagonal ring joint gaskets were produced from SS304 annealed stainless steel, suitable for high-pressure oil & gas service.

Key specifications include:

• Sizes: 1 13/16″, 1 1/2″, 3″, 4″
• Pressure ratings:
  • API 6A BX-151: 10,000 psi and 15,000 psi
  • ASME B16.20: Class 900 and Class 1500
• Profile: Octagonal
• Material: SS304 annealed

These API 6A ring joint gaskets BX-151 are commonly used with RTJ grooves to provide metal-to-metal sealing in high-pressure environments.

Spiral Wound Gaskets with SS316 and Graphite Filler

The order also includes a wide range of spiral wound gaskets manufactured to ASME B16.20, designed for RF flange connections.

Typical configurations:

• Sizes: 1/2″ to 6″
• Pressure classes: 150#, 300#, 600#
• Winding material: SS316
• Filler: Graphite
• Construction: Inner and outer rings

These SS316 spiral wound gaskets with graphite filler offer excellent sealing performance under fluctuating temperature and pressure, making them suitable for petrochemical, pipeline, and process industries.

RTJ Blind Flanges for High-Pressure Service

Haihao Group supplied RTJ blind flanges for both API 6A and ASME systems:

• API 6A BX-151 RTJ blind flanges
  • Size: 1-13/16″
  • Pressure ratings: 10,000 psi and 15,000 psi
  • Material: ASTM A182 F304
• ASME B16.5 RTJ blind flange
  • Size: 3″
  • Pressure class: 1500#
  • Material: ASTM A182 F304

These RTJ blind flanges for high-pressure pipelines are used to securely terminate piping systems while maintaining full pressure integrity.

RF Blind Flanges in Carbon Steel A105N

For standard pressure applications, RF blind flanges were supplied in carbon steel A105N:

• Size: 1 1/2″
• Pressure classes: 300# and 600#
• Standard: ASME B16.5
• Surface finish: Black painting

These A105N RF blind flanges are widely used in industrial piping systems for isolation and maintenance purposes.

Quality Control and Export Delivery

All flanges and gaskets underwent dimensional inspection, material verification, and visual checks prior to shipment. Haihao Group ensures that every product delivered to Singapore meets project requirements and international standards, supporting long-term operational safety.
