HASTELLOY FLANGE

Hastelloy steel flanges come in various types, each with its unique features and specifications. Understanding the different types of flanges available is the first step in choosing the right flange for your project.

The most common types of Hastelloy steel flanges include Weld Neck, Slip-On, Blind, Socket Weld, Lap Joint, and Threaded flanges.

Weld Neck flanges are designed to provide a long-lasting and leak-free connection. They're commonly used in high-pressure piping systems and have a neck that's welded to the pipe, creating a smooth transition between the pipe and flange.

Slip-On flanges are easy to install and remove and are ideal for low-pressure systems. They're slipped over the pipe and then welded in place.

Blind flanges are used to close the end of a pipe or vessel and are commonly used in systems that require periodic inspection or cleaning.

Socket Weld flanges are similar to slip-on flanges but have a socket in the bore to allow the pipe to be inserted. They're commonly used in small-bore piping systems and have a high-pressure rating.

Lap Joint flanges are designed to be used with a stub end and are ideal for systems that require frequent dismantling. They're commonly used in low-pressure systems.

Threaded flanges have internal threads and are screwed onto the pipe. They're commonly used in low-pressure systems and are easy to install and remove.

Hastelloy is a nickel and molybdenum alloy used to manufacture various products including flanges. They are divided into various grades. One type of pipe flange manufactured using C276 grades is the Hastelloy C276 Flanges. They can be used in welded conditions due to the suppression of carbide precipitation in the HAZ. Alloy C276 Weld Neck Flanges has carbon and silicon in it the content of it when reduced improves the corrosion resistance of these fittings. Nickel C276 Slip On Flanges displays resistance to wet chlorine gas, aggressive chemicals, and hypochlorite.
