Aesteiron Steels LLP is a leading Alloy Steel Pipe Fittings Manufacturer In India. We are specialized in manufacturing pipe fittings such as reducers, caps, elbow, tee, bend, coupling, union, nipple etc.
Alloy Steel Buttweld Fittings is a weldable pipe fitting that allows for change of direction of flow, to branch off, reduce pipe size or attach auxiliary equipment. It has many inherent advantages such as it provides permanent leak proof to the fittings. The continuous metal structure formed between fitting and pipe gives strength to the system. Smooth inner surface and gradual directional changes minimize the action of corrosion and erosion and reduce pressure losses and turbulence. It doesn't make it any less vulnerable to rust when exposed to the elements since it is ferrous
Alloy Steel Weld Fittings is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange. It is mainly used small pipe diameters generally for piping whose nominal diameter is NPS 2 or smaller. Its tensile strength of is between 758-1882 MPa which is higher than the tensile strength of stainless steel.
Low Alloy Steel Fittings is generally defined as having a 1.5% to 5% total alloy content. Its common alloying elements are chromium, manganese, silicon, molybdenum, nickel and vanadium. It is used for manufacturing of heating elements.
Alloy Steel Elbow is a key parts in a piping system for changing the fluid flow direction. It is useful to connect two pipes with different or same nominal diameters, and to make the pipe turn to a certain direction of 45 deg or 90 deg.
Alloy Steel Tee has three branches that can change fluid direction. It is widely used in pipe networks for convey liquids and gases. It is in T-shaped having two outlets, at 90° to the connection to the main line. It is a pipe short piece with a lateral outlet. It is widely used as pipe fittings.
