Duplex Slip-On Flanges

Duplex stainless steel slip on flanges are characterized by their high yield strength, which is twice that of the annealed yield strength of typical austenitic stainless steels, like 304 and 316 stainless steel slip on flanges.

As a leading supplier and manufacturer in China, GNEE Steel provides cost-effective nickel-based alloy products.

Product Introduction

Duplex Slip-on flanges are ideal for low-pressure applications. These flanges are very easy to install and weld onto different pipes. Furthermore, welding process reduces manufacturing costs. These Slip-On flanges do not require a large longitudinal space in the line to be fitted.

Features of Duplex Slip-On Flanges:

Duplex Slip-On are extremely corrosion resistant. Flanges possess high resistance to intergranular corrosion. Even in chloride and sulphide environments, duplex slip-on flanges show very high resistance to stress corrosion cracking. The duplex grades are even more resistant to corrosion.

Mechanical Properties of Duplex Slip-On Flanges:

• Density
• Melting Point
• Elongation
• Hardness

Advantages of our Duplex Slip-On Flanges:

• Typically lower in price than weld-neck flange, yet welding costs can be more.
• There is a reduced need to cut the pipe length accurately, making it easier to install.
• The slip-on flange is free to spin on the pipe for easy bolt alignment.
Applications of Duplex Slip-On Flanges:

Our company provide these flanges are used in various industries:

• Textile Industry
• Food Industry
• Transportation pipeline
• Energy Sector Industry
