Description
U bending tube is carried out by cold working method and is being done to the necessary bend radius as per client drawings. U-bend tube/pipe can be manufactured from an extensive range of pipe materials that contain high and low yield stainless steels, alloy steels, carbon steels,Monel , Inconel, hastelloy,duplex , super duplex,titanium,copper alloy and Cr-Ni alloys. Usually U-bends manufactured from seamless tube, can further be customized in terms of thicknesses and sizes as per the specific requirements of our clients. They are easy for further assemble tube bundles.
Grand provides U bend Tubes pipe in diverse industries for a range of applications such as in Boiler, Condensers, Super Heaters,tube bundles for Heat Exchangers, Coolers/Inter-coolers, Chiller, and so on. These are as well being used in dissimilar industries such as in Fertilizer Plants, Sugar Industry, Steel Plants,Oil & Gas plants, Chemical & Petrochemical plants, Refineries, Power plants, Renewable energy plants etc.

boiler tube,High pressure boiler tubes are used in high temperature and high pressure conditions. Steel tubes are subject to oxidation and corrosion under the action of high temperature flue gas and water vapor. The steel tube is required to have high lasting strength, high oxidation resistance corrosion performance and good stability.
