Títan U Beygja rör

Títan U Bend rör er framkvæmt með kaldri vinnuaðferð og er gert í nauðsynlegum beygjuradíus samkvæmt teikningum viðskiptavinar. U-beygja rör / pípa er hægt að framleiða úr miklu úrvali af pípuefnum sem innihalda ryðfríu stáli með mikilli og lítilli ávöxtun, stálblendi, kolefnisstál,Monel , Inconel, Hastelloy,Tvíhliða , super duplex,títan,Koparblendi og Cr-Ni málmblendi. Venjulega U-beygjur framleiddar úr óaðfinnanlegu röri, er hægt að aðlaga frekar hvað varðar þykkt og stærðir samkvæmt sérstökum kröfum viðskiptavina okkar. Þeir eru auðvelt fyrir frekari setja saman rör knippi.

Grand veitir U beygja rör pípu í fjölbreyttum atvinnugreinum fyrir margs konar forrit eins og í Boiler, Gufuþéttar,Uppgufunartæki,Pípubúnt fyrir varmaskipta, Kælir/millikælir, Svalaskápur, og svo framvegis. Þetta er eins vel notað í ólíkum iðnaði eins og í Áburðarverksmiðjum, Sykuriðnaður, Stálver,Olía & Gasver, Efnafræðilegur & Verksmiðjur sem eru unnar úr jarðolíu eða jarðgasi, Hreinsunarstöðvar, Orkuver, Endurnýjanleg orkuver o.s.frv..

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.

1. Staðall:ASTM B338/SB861, ASTM SB338/SB861, EN10204

2.Material Grade: GR1，GR2，Gr3，GR5，Gr7，Gr9，GR12，Gr16

3.Certification: ISO9001

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
