When your project operates at very high temperatures and under extreme pressure, material selection becomes critical. Stainless Steel 310 Flanges are specially designed for such demanding conditions. Known for excellent heat resistance, oxidation resistance, and mechanical strength, these flanges are widely used in refineries, power plants, petrochemical industries, and furnace systems.
As a trusted Stainless Steel 310 Flanges - Manufacturer, Supplier, we provide high-quality forged and machined flanges manufactured in compliance with international standards. Our range includes everything from ANSI B16.5 Stainless Steel 310 Flanges to custom-made flanges tailored to specific industrial requirements.
What is Stainless Steel 310?
Stainless Steel 310 is an austenitic stainless steel grade with high chromium (around 25%) and nickel (around 20%) content. This composition gives it outstanding resistance to oxidation and corrosion at temperatures up to 1100°C in continuous service.
It is also available in a low carbon version known as 310S, which offers improved weldability and reduced risk of carbide precipitation during welding.
Common international equivalents include:
- SS DIN 1.4841 Forged Flanges
- SS UNS S31000 Blind Flanges
- SUS 310 (Japanese designation)
Because of its high temperature performance, 310 stainless steel is widely used in heat exchangers, kilns, radiant tubes, and thermal processing equipment.
Stainless Steel 310 Pipe Flanges – Types We Supply
We manufacture and supply a complete range of Stainless Steel 310 Pipe Flanges suitable for various piping systems and pressure classes.
➤ ASTM A182 310 SS Weld Neck Flanges
ASTM A182 310 SS Weld Neck Flanges are designed with a long tapered hub that provides excellent stress distribution. They are ideal for high-pressure and high-temperature services. These flanges are commonly used in:
- Oil & gas pipelines
- Thermal power plants
- Chemical processing units
Their butt-weld connection ensures strong and leak-proof joints.
➤ 310 SS Slip On Flanges
310 SS Slip on Flanges are easy to install and cost-effective. The pipe is inserted into the flange and welded both inside and outside for added strength. They are commonly used in:
- Low to medium pressure applications
- Cooling water lines
- Fire protection systems
➤ SS 310 Lap Joint Flange
The SS 310 Lap Joint Flange is used with stub ends and is suitable for systems requiring frequent dismantling. It allows easy alignment of bolt holes. Benefits include:
- Easy installation and removal
- Cost savings when using expensive alloy materials
- Ideal for low-pressure systems
➤ SS Grade F310 Blind Flanges
SS Grade F310 Blind Flanges are used to close the ends of piping systems. They help in pressure testing and system expansion. We also supply:
- SS UNS S31000 Blind Flanges
- 310 Stainless Steel Spectacle Blind Flanges
Spectacle blinds are commonly used in oil & gas plants where line isolation is required for maintenance.
➤ A182 F310 Threaded Flange
The A182 F310 Threaded Flange is internally threaded and used where welding is not preferred. These are suitable for smaller diameter, high-pressure pipes. We also offer:
- SS 310 Threaded Flanges
- 310S Stainless Steel Screwed Flanges
They are commonly used in hazardous environments where welding sparks must be avoided.
➤ SS 1.4841 Socket Weld Flanges
SS 1.4841 Socket weld Flanges are designed for small bore, high-pressure piping systems. The pipe is inserted into a socket and welded around the hub. These flanges are widely used in:
- Hydraulic systems
- Steam lines
- Chemical processing plants
