Alloy Steel Pipe Fittings

Alloy Steel Pipe Fittings

The pipe fittings made with alloy steel has more than one element in its alloy, which helps to enhance its properties like strength, hardness, etc. The Alloy Steel Pipe Fittings are perfect for applications that require moderate corrosion resistance and good durability.

The Alloy Steel Fittings are available at a very economical cost, and they are mostly found in services where carbon steel would fail. There are two variants of alloy steel available, namely high and low alloy.

The AS Fittings are widely used in nuclear plants and power plants. This is because they are much stronger and harder than regular steel. But, it is to be noted that they do not have high corrosion resisting properties like that of stainless steel.

The alloy equal tee fitting is used as a branch that comes with the same diameter as that of the run pipe. The reducing Alloy Steel Tee is also used as a branch, but it has a smaller diameter compared to the run pipe. The Alloy Steel Reducer is more abundantly used than the equal tees as they have greater functionalities and can be used for more environments.

The ends of the Alloy Steel Buttweld Fittings are beveled, which means they have an angle forming between the edge of the end of the given pipe fitting. This beveled end is an essential part of the welding preparation process of joining the AS Pipe Fittings with the pipe.
