Kobs India is a leading manufacturer, exporter and supplier of Hastelloy Tee in a variety of shapes and dimensions. Also known as 3 way pipe fittings, tee fittings resemble the alphabet ‘T’, where in two horizontal pipes and one vertical pipe can be attached, to manage the direction and mixture of fluids. Pipe tees are widely used in piping systems to transport two phase fluid mixtures and are mainly of two types – Equal Tee and Unequal Tee (Reducing Tee).
Kobs India is a leading ISO 9001:2000 certified Company, has an exhaustive quality control and assessment procedure which takes care that only products that are defect-free and conforms to the set guidelines by respected international agencies. We are a manufacturer, supplier and exporter of Hastelloy Buttweld Equal Tee. Being corrosion resistant and give a quick disconnection in case of emergency. We export large quantities of ANSI B16.9 Equal Tee to industries like power plants, breweries, sugar, etc.

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.
