In Malaysia’s diverse industrial sectors—ranging from oil & gas and palm oil refining to municipal water systems—selecting the proper flange type is essential for ensuring system safety and longevity. Two of the most common options are the raised face flange and the flat faced flange, each designed for specific pressure and sealing needs.
As a trusted supplier of pipe fittings and flanges, Jizhong is proud to support Malaysian engineering and construction projects with high-quality flange products that meet global standards.
Raised Face Flanges (RF) by Jizhong
The raised face flange is the industry’s standard for pipelines under varying pressure and temperature conditions. The term “raised face” comes from the slightly elevated sealing area above the bolt circle where the gasket is positioned. This design allows for better gasket compression, improving the integrity of the seal.
In Malaysia, Jizhong’s raised face flanges are commonly used in:
- Oil & gas transmission pipelines in Sabah and Terengganu
- Offshore platforms and refineries
- Petrochemical and industrial processing systems
These flanges are manufactured according to ASME B16.5 and ASME B16.47, with surface finishes between 125 to 250 RMS. Higher pressure classes demand a thicker flange body, more bolts, and a larger raised face area for optimal sealing performance.
Flat Faced Flanges (FF) by Jizhong
The flat faced flange is designed for applications where the flange face must be perfectly flush with the bolt circle. This reduces bending stress during installation—especially important when connecting to cast iron or fiberglass flanged equipment.
In Malaysia, Jizhong flat faced flanges are widely used in:
- Low-pressure water pipelines in municipal and rural areas
- Palm oil factory piping systems
- Water treatment and irrigation infrastructure
These flanges are also manufactured with 125-250 RMS surface finishes per ASME B16.47 standards, ensuring reliable sealing in systems where flat contact is preferred.
Choosing the Right Flange for Malaysian Applications
Not sure whether a raised face flange or flat faced flange is best for your project? Here’s a general guide:
| Application Environment | Recommended Flange Type |
|---|---|
| High pressure / temperature | Raised Face Flange |
| Low pressure / static systems | Flat Faced Flange |
| Cast iron or brittle flange connections | Flat Faced Flange |
| Industrial / petrochemical pipelines | Raised Face Flange |
Jizhong provides technical support and custom flange solutions for clients throughout Malaysia. Whether your project is in Johor, Penang, Sarawak, or Kuala Lumpur, we help you choose the best flange type based on pressure rating, equipment materials, and installation environment.
