Titanium U Bend tube

Titanium U Bend 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,Evaporators,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.

Pure titanium grades have high corrosion resistance, excellent biocompatibility and good formability. They are classified based on their level of non-titanium elements and the resultant differences in mechanical properties. GR1 /GR2  have the lowest strength and best ductility of the four primary ASTM grades due to its higher level of purity. While grade 5 and gr9 are called titanium alloy, which are harder than gr1 and gr2 titanium.    Titanium alloy U tube bundles, Titanium tube for Heat Exchangers,Titanium Condensers tube,Titanium Evaporators tube,Titanium for Coolers/Inter-coolers.

Production process:

straight pipe – bending before 100% flaw detection – reliable bending machine and precision bending mould – bending after the U-shaped part of the electric heating stress relief annealing – bending after 100% water pressure

U TUBE TOLERANCES
Dimensional tolerances U tubes acc. to TEMA R.C.B.
1) Length of straight part -0/+5 mm
Flattening (also called “ovality”) at the bend shall not exceed 10% of the nominal tube outside diameter.
Wall thickness in bending part acc. to TEMA R.C.B 2.31
2) Minimum tube wall thickness in the bend part (T min)T(min) ≥ (SW × (2×R + D))/( 2× (R+D)
where: SW is smallest wall thickness
D Nominal outside diameter
R radius
3)Radius tolerance
1. for R 100 mm +/- 3 mm
2. for R ≥ 100 mm +/- 5 mm
4)Straightness tolerance max. 1,5 mm per 1 m
U-Tube ends: 

plain, vertically cut to the tube axis
