Applications
Blank Flange Plates are used in various industries, primarily for
sealing and connecting pipelines. Below are the common application
areas:
Oil and Gas Industry: In oil and gas pipeline systems, Blank Flange Plates are used to
seal pipeline ports, withstanding corrosive environments and high
operational pressures. They are particularly suitable for offshore
platforms and deep-sea pipeline systems.
Chemical Industry: Due to the excellent corrosion resistance of titanium alloys,
Blank Flange Plates are widely used in chemical pipelines to
prevent corrosion from acidic and corrosive chemicals, extending
the lifespan of equipment.
Marine Engineering: Titanium alloys offer outstanding resistance to corrosion, making
Blank Flange Plates suitable for marine pipeline systems, such as
seawater desalination plants, offshore platforms, and subsea
pipelines.
Water Treatment and Desalination: In water treatment and desalination plants, Blank Flange Plates
are used to seal pipeline ports, preventing seawater corrosion of
the pipeline system and ensuring long-term stable operation.
Aerospace: Blank Flange Plates are used in spacecraft piping systems,
capable of withstanding extreme temperatures and pressures,
suitable for spacecraft and satellite piping systems.
Shipbuilding: In ship pipeline systems, titanium alloy Blank Flange Plates
provide excellent resistance to seawater corrosion, widely used in
ship equipment and marine engineering pipelines.
Advantages of Blank Flange Plate
Excellent Corrosion Resistance: Titanium alloys have outstanding resistance to acids, bases,
salts, and seawater, making them suitable for extreme environments.
High Strength and Low Weight: Compared to steel, titanium alloys offer higher strength and
lower weight, making them ideal for applications where weight is a
strict consideration.
High-Temperature Performance: Especially Gr5 alloy, which maintains excellent strength at high
temperatures, is suitable for high-temperature pipeline systems.
Long-Term Reliability: The unique physical properties of titanium alloys ensure that
Blank Flange Plates can operate reliably in extreme conditions,
reducing maintenance and replacement frequency.
Low Maintenance Requirements: The corrosion resistance of titanium alloys significantly reduces
the need for maintenance and replacement, providing a
cost-effective long-term solution.
Quality Control and Manufacturing
Material Certification: All Blank Flange Plates are provided with complete material
certificates, ensuring compliance with DIN 2501 standards and
meeting the performance requirements of the selected alloy.
Dimensional Accuracy: Strict dimensional checks are conducted during the manufacturing
process to ensure that the flange plates' tolerances and sizes meet
the standard requirements.
Non-Destructive Testing (NDT): During batch production, non-destructive testing methods such as
ultrasonic, X-ray, or magnetic particle inspection are used to
ensure that the products are defect-free.
Surface Treatment: Each Blank Flange Plate undergoes surface treatment during
production to ensure a smooth surface free of impurities, enhancing
its sealing performance and corrosion resistance.
