Detailed Product Description
ASME SA790, S32205, S31803, S32750, S32760 Stainless Steel U Bend Tube U-Bend Tube are widely used in Heat Exchanger Systems. Heat-Exchanger Equipment on the basis of Seamless Stainless U-Tubes and Welded Stainless U bend Tube is essential in strategically important and critical felds---Nuclear And Petrochemical Machine Building. Zhejiang Yuhong Steel Company Start to Produce U Bending Tube Since 2006,Up to now already supply more than 10000 tons Stainless Steel U Bend Tube to 30 countries. The U-Bend Tube Comply With The Following Standards: 1. ASTM A688/ASME SA688 2. ASTM A803/ASME SA803 3. ASTM A556/ASME SA556 Steel Grade: Ferrite Austenite Duplex Super Duplex Ni-Alloys Titanium TP410 TP405 S44400 S44660 TP430 TP304/304L TP316/316L TP316Ti TP317/317L TP321 TP347 S31803 S32205 S32304 S32750 S32760 N06600 N08020 N00880 N08825 N08904 Gr.2 Tube Of Other Alloys And Steel Grades Can Be Produced Upon Agreement. Technical Requirements: Straight Tubes Standard Specification For Bending: ASME SA 213; ASME SB 163; ASME A789, ASME SA268, ASME SA269, etc. Marking: Before Bending By Marking Machine All Over The Tube Length (Bent Section After Heat Treatment Without Marking) Note: Marking is also possible After Bending On The Straight Parts Of U-Bending Tube. U-Bend Tubes: -TEMA RCB 2.31 Standard Of The Tubular Exchanger Manufacturers Association (9th Edition). -ASTM A688/ASME SA688 Standard Specification For Welded Tubes Of Austenitic Corrosion Resistant Steel Grade Designed For Feed Water Boilers. -ASTM B163/ASME SA163 Standard Techinical Requirements For Tubes Of Nickel And Nickel Alloy For Condensers And Heat Exchangers. -Customer Specifications. Bending Radius: From 1.5*OD(Outside Diameter) To 1500mm When Ordering Tubes With Radius less or equal to 1.5*OD, It Is Necessary To Agree Precision Of Geometrics. Straight Tubes Maximum Length:(Before Bending): 35000 mm. Leg Length: Min 1 Meter, Max. 16500 mm (For Max R=1500mm) Note: Other Size Are Available Upon Agreement. Heat Treatment: Stress Relieved After U-Bending (Bending Area Plus 300MM For Each Leg). Hydrostatic Test After U Bending: Maximum Test Pressure 600 Bar, Soaking 10 Sec. With Dematerialized Water. Compressed Air Cleaning After Hydro-Test. Packaging: In Strong Transport-Worthy Pre-fumigated wooden boxes of corresponding dimensions for each tube Length, Radius, Diameter, According To PO requirements as well as wrapped In polyethylene films With soft plastic caps on both end of Tube.
