What is a Flange?
A flange is a method used to connect pipes, valves, pumps, and other materials of equipment to form a piping system. It also allows for simple washing, inspection, and alteration. Flanges are generally welded or screwed together. Flanged joints are created by bolting two flanges together with a gasket between them to provide a seal.
Materials for Pipe flanges
Pipe flanges are typically made of various materials and grades. There are several materials that can be used in the manufacture of flanges. Carbon steel, high yield carbon steel, alloy steel, stainless steel, duplex and super duplex, and various nickel alloy grades such as Inconel, Incoloy, Hastelloy, and Monel are the most commonly used materials for pipe flange manufacture.
Types of flange
The type of flanges used in a piping application is chosen mainly by the required strength of the flanged joint. To ease maintenance operations, flanges are used instead of welded connections. A flange joint can be easily and quickly dismantled.
- Socket-Weld Flanges
- Threaded Flanges
- Blind Flanges
- Lap Joint Flanges
- Weld Neck Flanges
- Slip-on Flanges
- Ring Joint Face
- Tongue and Groove
Stainless Steel 316L Pipe Flanges
Stainless steel 316L Pipe Flanges has excellent corrosion resistance against sulfuric hydrochloric, acetic, formic, and tartaric acids, as well as acid sulphates and alkaline chlorides. They are commonly used in exhaust manifolds, heat exchangers, cryogenic piping, valve and pump trims in chemical and petrochemical processes, pulp and paper industry, and food industry, among other applications.
316L Stainless Steel Flanges, which are a low carbon version of 316 Stainless Steel Flanges. These flanges have responsibility of limiting the disastrous impacts of carbide precipitation. ASME SA182 316L Socket Weld Stainless Steel Flanges have greater creep resistance, can run in corrosive environments, and have good welded joints characteristics.
Intergranular corrosion resistance Stainless Steel 316L Threaded Pipe Flanges are as tough as nails in sub-zero temperatures, allowing them to be used in the petroleum industry. These flanges have a high creep rupture strength.
Stainless Steel 316L Blind flanges have good resistance to corrosive materials and are accessible in a variety of designs. The purpose of SS Lap joint Flanges is to connect a pipe to a recessed area of values, fittings, and flanges.
As a projection of a wedding effect on the pipes, Stainless Steel 316L Lap joint Flange is used to connect small bore pipes. These flanges are available in a variety of sizes, thicknesses, and pressure ratings, among other options.
Stainless steel 316L Weld Neck flanges are primarily used to lessen the curve from a larger size of pipe to a small size, resulting in higher pressure than before of the run.
Stainless Steel 316L Slip-on flanges are widely known due to their low material cost and ease of installation. There are several different diameters and low-pressure models to choose from. This flange, unlike welding neck flanges, lacks a neck to rest on the pipe, necessitating double welding.
Stainless steel Grade 316L Tongue and Groove Pipe Flanges are resistant to carbide precipitation, and are resistant to a wide range of corrosive fluids, and are used to attach pipes carrying chemical and corrosive materials.
316L Ring Joint Type (RT J) Stainless steel Pipe Flange is very ductile and quickly forms, but it is susceptible to work hardening during deformation and chip breaking.
