Large 2000mm OD Flange Manufacturer

As an important part of the connection system, large outer diameter flanges must have excellent mechanical properties, corrosion resistance and sealing performance. Baoji Fuqi Titanium-Nickel Pipe Fitting Co., LTD focuses on the research and development and manufacturing of ultra-large diameter, high-performance alloy material flanges, providing solid solutions for harsh working conditions.

 

1. Wide range of product sizes, suitable for a variety of engineering needs

The large outer diameter flanges we produce include:

NPS (imperial size): 56", 60"

DN (nominal diameter): DN1400, DN1500

Outer diameter size: 1400mm, 1500mm

Applicable to ultra-large pipe connection systems, meeting the special size requirements of large engineering pipe network systems.

 

2. Preferred high-performance metal materials

To meet the performance requirements under different working conditions, we provide a variety of material options, including but not limited to:

Titanium alloy: Gr.1, Gr.2, Gr.5, Gr.7, Gr.9, Gr.12

Nickel alloy: Ni-200, Ni-201

Zirconium alloy: Zr702, Zr705

These materials have significant advantages in corrosion resistance, strength, temperature resistance, etc., and are ideal for high-corrosion, high-temperature, and high-pressure environments.

3. Comply with international standards and have various pressure levels

The products are manufactured strictly in accordance with ASME B16.5 standards, covering:

Pressure levels: 150LB, 300LB, 600LB, 900LB, 1500LB, 2500LB

Can be applied to various pipe connection requirements from normal pressure systems to high pressure systems.

 

4. Precision machining to ensure sealing and matching accuracy

Processing method: Forging is used to ensure dense and defect-free organization

CNC precision machining to ensure the surface accuracy, tolerance, thread and sealing surface quality of each flange

Strictly implement multiple non-destructive testing processes to ensure that products are 100% qualified before leaving the factory

 

5. Wide application, serving global customers

Our products have been widely used in the following fields:

Corrosive media delivery system in chemical plants

Large fluid connection pipelines in ship systems

High-strength, temperature-resistant connectors in aerospace equipment

 

We not only provide customers with standard flanges, but also customize special-shaped structural parts according to drawings to meet the needs of various complex projects.
