Titanium U bøjningsrør

Titanium U bøjningsrør udføres ved koldbearbejdningsmetode og udføres til den nødvendige bøjningsradius i henhold til klienttegninger. U-bøjningsrør / rør kan fremstilles af et omfattende udvalg af rørmaterialer, der indeholder rustfrit stål med højt og lavt udbytte, legeret stål, kulstofstål,Monel , Inconel, Hastelloy,Duplex , super dupleks,titan,kobberlegering og Cr-Ni legeringer. Normalt U-bøjninger fremstillet af sømløse rør, kan yderligere tilpasses med hensyn til tykkelser og størrelser i henhold til vores kunders specifikke krav. De er nemme at samle rørbundter yderligere.

Grand leverer U bend Tubes rør i forskellige brancher til en række applikationer såsom i kedel, Kondensatorer,Fordampere,rørbundter til varmevekslere, Kølere/Inter-kølere, Chiller, og så videre. Disse bruges også i forskellige industrier som i gødningsanlæg, Sukkerindustrien, Stålværker,Olie & Gasanlæg, Kemisk & Petrokemiske anlæg, Raffinaderier, Kraftværker, Vedvarende energianlæg mv.

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

Pakning:

Packed in ply wooden box wrapped in plastic, and suitably protected for sea-worthily delivery or as requested.
