Custom Flanges
Custom flanges are the interconnected parts between the shafts, which are used for the connection between the pipe ends.
Seather provides custom flange templates for you to modify to your liking to get a better understanding of your project application.
Additionally, drawings for approval can be requested prior to actual manufacturing, provided an order already stands.
From raw materials forgings to finished custom flanges, Seather here is sure to help it!

Custom Flanges: The Ultimate Guide
Regardless of custom sizing or specifications, the fundamental design of most custom flanges falls under six common styles created to close, connect, cover, or support pipes and pipe systems.
When you choose to buy custom made flanges, there have some important points we need to know before we get started.
What are Custom Flanges?
Custom flanges are made of custom alloy forgings and round plates.
As the name implies, do not have standards, they are non-standard parts and require buyers to provide detailed drawings.
Custom Flanges Applications
Custom stainless steel and nickel alloy flanges are used in many fields, such as:
- Oil&Gas industry
- Chemical processing
- Pollution & Waste
- Marine
- Power plants and nuclear power
- Food and beverage processing
- Piping system manufacturing
- Valves & Actuators
- Heating systems
- Welding products
Features of Custom Flanges
- Corrosion resistant
- High tensile strength
- Very durable
- Temperature resistant
- Easy formability and fabrication
- Low-maintenance
- Attractive appearance
- Environmentally friendly (recyclable)
What Are Custom Flanges Surface Treatment?
Surface treatment is one of the major part in whole production.
Different surface finish will be used for different custom flanges.
With methods including anodizing, passivation, brushing, polishing, blackened, plating, painting, powder coating, heat treatment, surface phosphating, hot dip galvanizing, surface treatment dacromet, etc.
Key Considerations When Buying Custom Flanges
When purchase the custom flanges from China manufacturer, you should know the standards, size, materials grades, production process, drawings details, etc.
Below Is One Sample Purchasing Tips For Your Reference
- Standards: ASTM A240
- Material Grade: 904L stainless steel
- Size: As your drawing request
- Usage: Pressure vessel
- Production Process: CNC machined
- Tolerance: -1mm/+1mm
- Requirement On Properties: As your request
- Order Quantity, Delivery Time, Shipping Method, Place Of Delivery, Packaging Requirement, etc. should be considered.
