Haihao Group Supplies SA-516-70N Paddle Blind Flanges to Indonesia
Haihao Group recently completed the production and shipment of a batch of paddle blind flanges for a pipeline project in Indonesia. These pipeline components were manufactured using SA-516-70N carbon steel and produced in accordance with ASME B16.48 standards to ensure reliable performance in industrial piping systems.
The delivered paddle blind flanges feature raised face (RF) sealing surfaces and are designed for 2-inch pipelines with pressure classes of 150# and 300#. These fittings are widely used in oil, gas, and chemical pipeline systems where safe and efficient pipeline isolation is required.

Advantages of Paddle Blind Flanges
Using paddle blind flanges provides several practical benefits in industrial piping systems.
Reliable Pipeline Isolation
A paddle blind flange allows operators to block or allow pipeline flow by simply rotating the paddle plate between the flanges.
High Strength Material
The SA-516-70N material offers excellent mechanical strength and good pressure resistance, making it suitable for demanding pipeline applications.
Compliance with International Standards
Manufactured according to ASME B16.48, these paddle blind flanges meet global engineering requirements for line blanking devices.
Easy Installation and Maintenance
Because of their simple structure, paddle blind flanges are widely used in pipelines that require frequent inspection or system shutdown.
Applications of Paddle Blind Flanges
The paddle blind flanges supplied to the Indonesian customer are suitable for various industrial sectors where pipeline isolation is critical.
Typical applications include:
- Oil and gas pipeline systems
- Petrochemical plants
- Refinery processing units
