A flange is often shaped like a disc and is used to link two tubes or a pipe to a tee, valve, or other component that connects them. For stability and strength, most pipe ends have two flanges with a gasket between them.
Flanges are used to connect two pipe joints. Metal Yard is a well-known flanges manufacturer and supplier, supplying carbon steel, stainless steel, and alloys.
Metal yard flanges are necessary for almost every pipe installation and come in widths ranging from 1/2″ (15 NB) to 48″ (1200 NB).
Materials for Flanges
Pipe flanges can be made from stainless steel, alloy steel, carbon steel, Monel, Inconel, and other metals in different grades, but the most common material is forged carbon steel with machined surfaces.
The material of the pipe largely determines the material of the flange; frequently, they are both made of the same material.
Flanges of Many Types
The blind flange is used to cover the end of pipe systems and halt the flow, making pressure testing straightforward. A blind flange is a plate that is used to cover or close the end of a pipe.
A flange junction is a pipe connection where the connecting parts have flanges that hold the portions together.
While the term flange normally refers to a fitting’s raised rim or lip, certain flanged plumbing fittings are also called flanges.
Threaded flanges are used in unusual situations, and their main benefit is that they can be attached to the pipe without welding.
Threaded flanges are readily removed. In addition to the threaded flange connection, a seal weld is sometimes used.
The name for this sort of flange gives away the fact that it has a diameter that is slightly bigger than the pipe in order to allow it to slip over the pipe while maintaining a secure fit.
They are strong, durable, and cost-efficient, despite the fact that they are thinner than the majority of other flanges.
Lap Joint Flange
Lap joint flanges are usually combined with a stub end or splice that is butt-welded to the pipe, and the lap joint flange is left unfastened behind it.
The stub end is always making the face. Lap joint flanges are utilized in systems that must be cleaned often.
Lap joint flanges are popular in low-pressure applications because they are simple to build and align.
These flanges resemble slip-ons, but they are identified by the rounded internal edge of the flange face. Lap joint flanges may be provided without a hub or in treated, coated carbon steel to save money.
Welding Neck Flange
This kind of flange is often used in high-pressure applications to lessen the concentration of stress. It has a neck that is welded to the bottom of the pipes. Inconel 600 flanges are a popular option for high-pressure systems because they provide strength and flexibility.
