Detailed Product Description
ASME SA269,ASME SA213, A1016, TP347 / TP347H Exchanger
YUHONG GROUP deal with Austenitic Stainless Steel, Nickel Alloy Steel (Hastelloy , Monel, Inconel, Incoloy ) seamless and welded pipe and tube already more than 25 years, every year sell more than 80000 tons of steel pipe and tube. Our client already cover more than 45 countries, Like Italy, UK, Gernmany, USA, Canada, Chile, Colombia, Saudi Arabia, Russia, Korea, Singapore, Austrial, Poland, France , ....And our group branch company and factory have been already approved by :ABS, DNV, GL, BV, PED 97/23/EC, AD2000-WO, GOST9941-81, CCS, TS, CNNC, ISO9001-2008, ISO 14001-2004.
Applications The common application fields are:
- heat exchangers (condensers, evaporators, sea water desalinators)
- chemical and petrochemical industries
- food processing and refrigeration industries
U-bent tubes are manufactured according to the technical specifications requested by customers:
- Outside diameter of the tube: 6 ÷ 90 mm.
- Maximum overall length: > 26 m.
- Bending radius (min.): 1,5 × tube diameter.
- Bending radius (max.): 1200 mm.
- Heat treatment (by Joule effect on bent area) in inner and outer inert atmosphere.
- Anti oxidation surface treatment (with protective oils).
- Trimming and deburring of the ends.
- Internal cleaning and caps insertion.
- Packing in custom racks.
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.
YUHONG Group Start to Produce U Bending Tube Since 2006,Up to now already supply more than
30000 tons Stainless Steel U Bend Tube to 35 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
Tube Of Other Alloys And Steel Grades Can Be Produced Upon Agreement.
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.
-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.
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.
Some of the quality tests carried out by us includes:
|Corrosion Test||Conducted only when specially requested by the client|
|Chemical Analysis||Test done as per required quality standards|
|Destructive / Mechanical Testing||Tensile | Hardness | Flattening | Flare | Flange|
|Reverse-bend and Re. flat tests||Carried out in full compliance with relevant standards & ASTM A-450 and A-530 norms, which ensures trouble-free expansion, welding & use at customers end|
|Eddy Current Testing||Done to detect homogeneities in subsurface by using Digital Flaw-mark Testing System|
|Hydrostatic Testing||100% Hydrostatic Testing carried out according to ASTM-A 450 norms for checking tube leakage, and biggest pressure we can support 20Mpa/7s .|
|Air Under Pressure Test||To check any evidence of air leakage|
|Visual Inspection||After passivation, every single length of tubes & pipes is subjected to thorough visual inspection by trained staff for detecting surface flaws & other imperfections|
Supplementary Testing : Apart from the above mentioned tests, we also carry out on the manufactured products supplementary testing. The tests conducted under this include:
"All we do is usually connected with our tenet "" Client very first, Belief first, devoting about the food stuff packaging and environmental security for ASME SA213 TP347 Heat Exchanger U Bend Tube. The product will supply to all over the world, such as: Jordan,Brunei Darussalam,Venezuela. to have a bright future together.
