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.
Some of the quality tests carried out by us includes:

Corrosion Test
Conducted only when specially requested by the client
Chemical AnalysisTest done as per required quality standards
Destructive / Mechanical TestingTensile | Hardness | Flattening | Flare | Flange
Reverse-bend and Re. flat testsCarried 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 TestingDone to detect homogeneities in subsurface by using Digital Flaw-mark Testing System
Hydrostatic Testing100% 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 TestTo check any evidence of air leakage
Visual InspectionAfter 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:
