Kobs Pipe is one of the best supplier and manufacturer of Duplex Steel Buttweld Elbow. The function of Duplex Steel Buttweld Elbow is to change direction of flow in a piping system. Elbows are split into three groups, which define the distance over which they change direction, which is expressed as a function of the distance from the centre line of one end to the opposite face.
Kobs India offers a wide range of Duplex Steel Buttweld Elbow, which is manufactured at par with the international quality standards making use of high-grade steel. Duplex Steel Elbow Butt Weld Pipe Fittings is stainless steel is a stainless steel whose design enables combining improved resistance to pitting, high strength, stress corrosion, crevice corrosion and cracking. Duplex Steel S31803 Tee Butt Weld Pipe Fittings is often used in Chemical Process Industry: such as in Sulphuric Acid Production, Nitric Acid Processes, Phosphoric Acid Processes, Ethylene oxide, Polypropylene Production, PVC, Equipment Handling Organic and Fatty Acids, Chemical Storage and Tankers, Heat Exchangers, etc. Duplex Steel S31803 Reducer Pipe Fittings resists chloride environments and sulphide stress corrosion.

The principal methods of hot working are extrusion, drawing, forging and rolling. Rolling is the most extensive employed forming process, though some limitations may apply to the process. Rolling mainly consists of three major sub-categories: flat rolling, shape rolling (with specifically designed roll grooves) and pipe rolling (including piercing). Forging may be sub-categorized as hamming, pressing, etc. .
Forging may be performed under hammers, in mechanical presses and upsetters or by a method known as roll forging. Pressing generally includes the manufacture of forged articles in hydraulic presses. Extrusion usually is performed in hydraulic presses which force the hot steel through a die. Rolling is performed in rolling mills of a variety of types. .
The two principal reasons for perform metal forming at elevated temperatures (hot working) are to reduce the forming loads through the reduction of the resistance of the steel to deformation, and to develop preferred metallurgical structures for strength and ductility of the finish products.
The most appropriate manufacturing method of a product will be decided with consideration of its material, sizes, shape, use, standards and other properties.
