Flange Adaptor

Ductile Iron Flange Adaptor

More

A Flange Adaptor is a versatile pipeline component designed to bridge connections between flanged pipes, valves, or fittings with differing specifications, ensuring compatibility in diverse fluid systems. Its structure features two flanged ends—one matching the dimensions of the existing pipeline Flange and the other adapting to the target component’s flange size, pressure class, or bolt pattern—creating a secure, leak-tight transition.​

Constructed from durable materials tailored to application needs, common options include carbon steel for industrial pipelines, stainless steel (304 or 316) for corrosive environments, and ductile iron for water or sewage systems. The material selection ensures resistance to media such as oils, chemicals, water, and gases, while withstanding operational temperatures and pressures specific to the system.​

Key design features include precision-machined flange faces, proper bolt hole alignment, and gasket seating surfaces that prevent leakage. Available in reducing (connecting different diameters) or same-size (matching different pressure classes) configurations, it eliminates the need for custom fabrication when integrating components from different manufacturers or standards (e.g., ANSI to DIN flanges).​

In system integration, it works synergistically with critical components: paired with Steel Tees or Reducer Pipes, it resolves flange mismatches in branch connections. It enables compatibility between Butterfly Valves and pipeline flanges, simplifies installation of Bellow Expansion Joints with non-standard flanges, and facilitates connections between Dismantling Joints and varying pipeline specs.​

Key advantages include flexibility, cost savings, and reduced installation time. By eliminating the need to replace entire pipeline sections, it streamlines system upgrades or repairs. Its robust design ensures long-term reliability, making it indispensable in industrial, commercial, and municipal fluid systems where diverse flange standards or component mismatches are common.
Flange Adaptor
A flange adaptor is a connecting element primarily used to join two different types of flanges when they cannot be directly fitted together. When two different flanges are connected through the adaptor, bolts are tightened, and a sealing gasket serves to fill and seal the gap, preventing the leakage of liquids or gases. Additionally, it transmits pressure and torque, ensuring the strength and reliability of the connection.

FAQ
Important things you should know
1
why should you buy from us not from other suppliers?
Quality assurance! The price is the lowest in the industry!professional customer service, and extensive industry experience.
2
What is the difference between a flange adapter and a dismantling joint?
Flange adapters are primarily made of cast iron, while dismantling joints are mainly composed of materials such as carbon steel and stainless steel. Flange adapters do not have flanges on them, whereas dismantling joints are equipped with multiple flanges.
3
When to use a flange adapter?
Connecting Different Materials，Connecting Different Specifications，Special Applications and Maintenance and Retrofitting.
