Alloy Steel Flanges is a forged or cast ring of steel designed to connect mechanically sections of pipe or join pipe to a pressure vessel, valve, pump any other piece of equipment.
These alloys typically comprise of about 1 % to 5% of the steel’s content and are usually added based on their ability to provide a very specific attribute for their end use.
For instance, the addition of molybdenum in the alloy steel plate flanges, offers an improved material strength.
Adding nickel adds toughness to the alloy. Similarly adding chromium to chrome moly flanges aids in enhancing other mechanical properties such as temperature strength, hardness, as well as corrosion resistance.
Besides these elements the addition of trace amounts of both Manganese and silicon, other set of common alloying elements, provides the alloy steel threaded flanges with excellent deoxidizing capabilities.
Despite adding these elements, low alloy steel flanges aren’t necessarily difficult to weld. The key to achieve a successful performance of the welding operation is by knowing exactly what type of low-alloy steel you have.
Which means that one has to know if the alloy steel flange material is critical to achieving good weld integrity and the need for proper filler metal selection.High heat resistance steel grades are generally known as Chromium Molybdenum Steel.
A low alloy steel flanges series mostly consists of approximately 0.5% to 9% of Chromium. And the content of Molybdenum in the alloy steel flanges ranges anywhere between 0.5% to 1% .
Alloy Steel Flange Material can differ according to its chemical composition. Low Alloy Steel Flanges are widely used for automotive and aerospace bodies, offshore and onshore structural engineering plates and railway lines.
The Chromium content in the alloy aids in improving its anti-oxidization and anti-corrosion properties. This steel is usually supplied by the alloy steel flanges manufacturers in India in an annealed or normalized and tempered condition.
Chromium-Molybdenum alloy steel flanges dimensions has been widely used in the many areas. Their utilization can be seen in areas such as steam power equipment, petrol chemical industry, and high temperature services.
It has chemical composition, such as nickel, nickel-chromium, molybdenum, chromium-molybdenum steels etc.
Chrome moly flanges provide improved levels of chromium and molybdenum. The addition of chromium helps to increase itshardenability and corrosion resistance,
Flange is usually used for connecting pipes or valves, so it can solve the above problems easily.
These Alloy F5 Flange are used for transferring liquid and other fluids to several industries. We are manufactured by a team of nimble-fingered professionals using high quality raw material, modern tools and advance technology.
The flange connection type usually comes with double units, with a gasket and some bolts & nuts to connect each other. (Firstly pipes are welded on the flanges, then valves and other equipment could be installed on flanges.)
When connecting these parts, put gasket in the middle of two flanges, then tightening the flange screws, so the two will be connected together tightly.
In case pipeline maintenance, we can remove screws on the flange, take away corresponding pipes or valves. Meanwhile to replace new pipes and valves.
Flange connection has good strength and sealing, simple structure and low cost. It can be repeatedly disassembled.
The flange connection mainly have leakage problem, and the leakage quantity should be controlled within the allowable range of process and environment.
Alloy Steel Flanges are made in different steel alloys. The flanges vary in dimensions and types. There are ? inches through 48 inches of nominal diameter sizes of flanges.
ASTM A182 Low Alloy Steel flanges as well as the other types of alloys. The ASTM A 182 specification specifies flanges for high pressure services.
The flanges also come in B16.5, B16.47 and other standards and dimensions. The Alloy Steel Flange Material can vary according to the chemical composition.
The ANSI B16.5 Alloy Steel Slip On Flange is a flange type that allows the pipes to slip onto the flange and makes the connection in a precise locations.
The Alloy Steel Blind Flanges are used to close a pipe connection. There are different types and grades of the blind flanges as well.
There are other different types of ASME SA 182 AS Pipe Flanges such as the weld neck flanges and socket weld flanges each specified for a particular role.
The flanges can be threaded, ring type joint, lap joint, weld neck or socket welded.
The Alloy Steel Weld Neck Flange has a welded neck onto it that holds larger pipes in place for easy welding and installation.
We feel proud to introduce ourselves as the well-known manufacturers, exporters and suppliers of Alloy Steel F21 Flanges.
The connection between two pipes can be directly welded together, but it is difficult to connect together without welding. When the connection part have problems, it will be hard to repair. The same problem also happened between pipe and valve connection.
