ASME SA213 Alloy Seamless Steel T9 Bend U Boiler Tubes
YuHong Group can offer SA213/A213 alloy stainless steel bend U
tubes and we sell these products with best quality in more than 70
countries.
ASME SA213 / ASTM A213 This specification covers seamless ferritic and austenitic steel
boiler, superheater, and heat-exchanger tubes, designated Grades
T9, TP304L, TP316L,etc.
U tubes are manufactured by bending straight tubes. Bending is done
cold on an automatic U-bend. For ensuring tube wall thinning and
diameter ovality are controlled, tube bending is accomplished with
a mandrel inserted into the tube. Besides, the U-bend of the U-tube
is stress relieved under controlled conditions and cycles for
extended life.
Specifications
| Sizes / Thickness | Usually furnished to this specifification are 1 ⁄ 8 in. [3.2 mm] in inside diameter to 5 in. [127 mm] in outside diameter and 0.015 to 0.500 in. [0.4 to 12.7 mm], inclusive, in minimum wall thickness or, if specifified in the order, average wall thickness. | ||||
| Manufacture | seamless process; hot finished or cold finished, as specified. | ||||
| Heat Treatment | seamless tubing immediately following hot forming may be
individually quenched in water or rapidly cooled by other means,
provided that the temperature of the tubes after hot forming is not
less than the minimum specifified solution temperature (direct quenched). | ||||
| Length | As required by clients | ||||
| Surface Condition | *Cold-fifinished steel tubes shall be free of scale and suitable
for inspection. A slight amount of oxidation is not considered
scale. *Hot-fifinished steel tubes shall be free of loose scale and
suitable for inspection. *Stainless steel tubes shall be pickled free of scale.When bright
annealing is used, pickling is not necessary. | ||||
| Bending Radius | From 1.5*OD(Outside Diameter) To 1500mm, ≤1.5*OD,necessary To agree precision of geometrics | ||||
| Straight Tubes | max length 35000mm | ||||
Alloy Steel T9 EFW Tubes created in ostensible or least divider thickness for high temperature administration.SA213 T9 seamless tube with long length are accessible in hot moved condition up to 22.5m. Consistent ferritic combination steel T9 tube can be provided to meet unique surface prerequisites and additionally close measurement and divider thickness resilience.
ASME SA213 T9 alloy steel seamless tube is emphatically prescribed to utilized in an assortment of plants and procedures over the globe including refineries, control plants, petrol-synthetic plants, high and very high temperature lines, refining, oil field administrations, and so on.
