- About Us
VIPA Australia is a trusted manufacturer specializing in the production of high-quality flanges. With a commitment to precision engineering and top-tier materials, VIPA delivers flanges that meet the highest industry standards. Whether for industrial, oil and gas, or infrastructure projects, VIPA flanges are designed for durability, reliability, and performance. Their product range includes a variety of flange types, including welded, slip-on, and blind flanges, all manufactured with the utmost attention to detail and quality control.
The added strength of an ANSI certified flange contributes to high performance mechanical systems, structures, and assemblies across the United States and around the world. Tested and certified to meet the specifications of the American National Standards Institute, ANSI Class Flanges carry the organization’s seal of approval for the toughest jobs.
ANSI (American National Standards Institute) is a private, non-profit organization that oversees and sets voluntary standards for products, services, processes, and systems in the United States. It ensures that industries follow consistent safety, quality, and performance guidelines.
The stamp of ASME certification denotes high performance capabilities for engineered components around the world. Tested and certified according to the research and standards of the American Society of Mechanical Engineers, these mechanical assemblies, systems, and structures bear the weight of the toughest jobs and highest expectations.
ASME (American Society of Mechanical Engineers) is a professional organization that sets internationally recognized codes and standards for engineering, particularly in mechanical systems.
AWWA (American Water Works Association) flange standards define the design, dimensions, drilling, materials, and pressure ratings for flanges used in waterworks applications. These flanges are commonly used in municipal water supply systems, wastewater treatment plants, and industrial applications.
The most widely recognized standard for AWWA flanges is:
1. AWWA C207 – Steel Pipe Flanges for Waterworks Service
This standard covers steel-ring and blind flanges used in waterworks applications. It is different from ASME/ANSI standards, as AWWA flanges are designed for lower pressures and larger pipe sizes.
2. AWWA C228 – Stainless-Steel Pipe Flanges
This standard provides specifications for stainless-steel flanges used in water systems.

- Our Solution
STEP
Identify the type of flange required (Weld Neck, Slip-On, Blind, etc.).
Choose the appropriate material (carbon steel, stainless steel, alloy steel) based on pressure, temperature, and application.
Ensure compliance with industry standards (ASME, ANSI, DIN, etc.).
STEP
Cutting & Shaping: Raw material is cut and shaped using CNC machines or forging.
Machining: Drilling bolt holes, threading (if required), and surface finishing.
Testing: Non-destructive testing (NDT), pressure tests, and dimensional checks to ensure quality.
STEP
Preparation: Clean and inspect flange surfaces before assembly.
Assembly: Align flanges properly, use the correct gaskets, and tighten bolts as per torque guidelines.
Final Check: Conduct leak testing and ensure proper alignment before operation.
- Frequently asked questions
What are the main types of flanges used in industrial applications?
The most common flange types include Weld Neck, Slip-On, Blind, Socket Weld, Threaded, Lap Joint, and Orifice Flanges, each designed for specific pressure and application requirements.How do I select the right flange material?
Material selection depends on factors like temperature, pressure, corrosion resistance, and industry standards. Common materials include carbon steel, stainless steel, alloy steel, and duplex steel.What are the key quality tests performed on flanges?
Flanges undergo various quality tests, including:
- Non-Destructive Testing (NDT) – Ultrasonic or radiographic testing.
- Dimensional Checks – Ensuring bolt hole alignment and face flatness.
- Pressure Testing – Verifying the flange's strength under working conditions.
How should flanges be installed to ensure a leak-proof connection?
- Ensure the flange faces are clean and smooth.
- Use the correct gasket based on the application.
- Align the bolt holes properly before tightening bolts in a crisscross pattern.
- Follow proper torque specifications to prevent leaks.
