Tiub Titanium U Bend

Tiub Titanium U Bend dijalankan dengan kaedah kerja sejuk dan sedang dilakukan ke jejari selekoh yang diperlukan mengikut lukisan pelanggan. Tube / paip U-bengkok boleh dihasilkan dari pelbagai bahan paip yang mengandungi keluli tahan karat hasil tinggi dan rendah, keluli aloi, keluli karbon,Monel , Inconel, Hastelloy,Dupleks , Super Dupleks,titanium,aloi tembaga dan aloi Cr-Ni. Biasanya selekoh U dihasilkan daripada tiub lancar, boleh disesuaikan dari segi ketebalan dan saiz mengikut keperluan khusus pelanggan kami. Mereka mudah untuk memasang lagi himpunan tiub.

Grand menyediakan paip U bengkok Tubes dalam pelbagai industri untuk pelbagai aplikasi seperti dalam Dandang, Pemeluwapan,Penyejat,pakej tiub untuk penukar haba, Penyejuk / Inter-penyejuk, Penyejuk, dan sebagainya. Ini juga digunakan dalam industri yang berbeza seperti dalam Loji Baja, Industri Gula, Loji Keluli,Minyak & Loji gas, Kimia & Loji petrokimia, Kilang penapis, Loji kuasa, Loji tenaga boleh diperbaharui dan lain-lain.

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

Packing:

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