钛U型弯管

钛U型弯管通过冷加工方法进行，并根据客户图纸完成必要的弯曲半径. U型弯管/管可以由含有高产量和低产量不锈钢的各种管材制成, 合金钢, 碳钢,蒙乃尔 , 镍 铁合金, 哈氏合金,双工 , 超级双工,钛,铜合金和铬镍合金. 通常由无缝管制成的 U 型弯管, 可以根据客户的具体要求进一步定制厚度和尺寸. 它们易于进一步组装管束.

格兰德为各种行业提供U型弯管管，用于锅炉等一系列应用, 冷凝 器,蒸发器,用于热交换器的管束, 冷却器/中间冷却器, 式 制冷机, 等等. 这些也用于不同的行业，如化肥厂, 制糖业, 钢铁厂,油 & 天然气厂, 化学的 & 石化厂, 炼油 厂, 电厂, 可再生能源工厂等.

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 毫米
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(最小) ≥ (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 毫米 +/- 3 毫米
2. for R ≥ 100 毫米 +/- 5 毫米
4)Straightness tolerance max. 1,5 mm per 1 m
U-Tube ends:

plain, vertically cut to the tube axis

包装:

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