Key Features
Corrosion Resistance
The high chromium content in stainless steel creates a protective passive layer, making the flanges highly resistant to rust, staining, and chemical attacks.
High Strength and Durability
Stainless steel flanges possess high tensile strength and durability, making them suitable for demanding industrial conditions.
High-Temperature Resistance
They are designed to withstand extreme temperatures without degrading, a critical feature for power generation and chemical processing.
Hygiene and Cleanliness
The non-porous surface of stainless steel prevents the harboring of bacteria and pathogens, making these flanges ideal for the food, beverage, and pharmaceutical sectors.
Types of Stainless Steel Flangess Available
Integral steel pipe flange:
Directly integrated with the pipe.
01
Threaded steel pipe flange with neck:
A neck with threaded connection.
02
Welded steel pipe flange:
Suitable for high-pressure systems, connected to pipelines through welding
03
Flat welded steel pipe flange with neck:
Having a neck that can be connected to a pipeline by welding,
04
Neck socket welded steel pipe flange:
Used for inserting pipe ends and fixing them by welding.
05
Applications
Chemical Industry
Essential for transporting corrosive, hazardous, and delicate chemical fluids safely.
Food & Beverage and Pharmaceutical Manufacturing
Preferred for sanitary connections in processing and manufacturing, owing to their corrosion resistance and ability to prevent contamination.
Water Treatment
Utilized to construct pipelines for transporting treated water and other fluids under various pressure conditions.
Power Generation
Employed to convey high-temperature and high-pressure fluids in power plants.
