How to choose stainless flange

Pinpointing the perfect stainless flange for your project starts with assessing the key components. First is the diameter, which must correspond to the size of the flange. Next is its thickness, a measure of its dependable structural capacity. Last is the material, determining just how resistant it will be to corrosion. With these three characteristics defined, you can proceed to choose your ideal flange.

Offering up a variety of sizes and material grades, weld neck flanges are the go-to flange when designing for welding to a pipe or fitting. The most used option is the ANSI 150# which comfortably accommodates pipes up to 24 inches in diameter, while the heavier duty ANSI 300# is implemented for those larger than that. Popular material grades include 304, 316, and 317.

For large-diameter pipe connections, the slip-on flange is ideal. This type of stainless steel flange slides over the outside of the tube or joint it is joining. Available in numerous sizes, most often used are the ANSI 150# slip-on flange for pipes up to 24 inches in diameter and the ANSI 300# for diameters exceeding 24 inches. The commonly used material grades are 304, 316, and 317.

To enable installation onto various pipe or fittings, the threaded flange is crafted in a selection of sizes and material grades. Frequently employed for pipe diameters up to 24 inches, the ANSI 150# threaded flange is particularly popular. On the other hand, models of ANSI 300# are necessary for diameters beyond 24 inches. Provided in stainless steel varieties of 304, 316, and 317, it offers considerable scope for customisation.

A blind flange is the fourth type of stainless flange offered and is used to cap off the tail end of a piping system. Available in a variety of sizes and material grades, the ANSI 150# blind flange is typically used for piping that has a diameter of 24 inches or less; while piping with a diameter greater than 24 inches would require the ANSI 300# blind flange. As far as material grades go, these can range from 304, 316, and 317.

Stocking sizes and material grades, the fifth kind of stainless steel flange is the lap joint flange, which is meant to be used together with a lap joint stub end. Commonly, ANSI 150# lap joint flanges are employed for a pipe diameter under 24 inches. If the pipe size is beyond that, it takes an ANSI 300# lap joint flange. With 304, 316, and 317 forming the material grades, the lap joint flange can accommodate pipes of various sizes.

The orifice flange is one of the six varieties of stainless steel flanges which is employed to assess the flow of liquid in an interconnected piping network. This type of flange is offered in various sizes and manufactured from premium quality 304, 316, and 317 metals. ANSI 150# orifice flange is used for network pipelines up to 24 inches in circumference, whereas the ANSI 300# variety is necessary for pipings exceeding 24 inches in diameter.

An ANSI 150# reducing flange of diverse sizes and material grades is the seventh stainless flange type and is used to bridge two pipes of different diameters. The most popular size accommodates tubing up to 24 inches wide, whereas the ANSI 300# variation is designed for larger pipe sizes. The three material grades offered are 304, 316, and 317.

For those in need of temporarily blocking off one section of pipe while providing access to the other, the Spectacle Flange is the answer. Varied sizes and material grades are available to accommodate any project. Amongst the top-requested offerings are ANSI 150# and 300# spectacle flanges for pipes of 24 inches and over; while 304, 316, and 317 materials are commonly chosen for their superior grades.

The ninth category of stainless flanges is the Socket Welding variety. These flanges are designed to securely join two parts via an internal socket – ensuring a tight and durable link. While the Socket Welding flange does not require gaskets, their careful installation is necessary for proper fit and performance.
