Detailed Product Description

ASME SA249 A688 ASME SA213 Stainless Steel U Bends TP304 / TP304L / TP304H / TP321

Quick Detail:
Stainless Steel U Bend Tube ASME B163 B677 TP904 / 904L Pickled and Annealed

Dimensions:

OD:12.7mm---38.1mm
WT: 0.89~2.77mm
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).
"U" Stainless Steel Tubes are manufactured in our plant as per the customer requirements. Bend can be Heat Treated in accordance with Client's Requirements followed by hydrostatic testing and dye penetrant testing if required.
U-bend stainless steel tubes are widely used in heat-exchanger systems.Heat exchanger equipment on the basis of seamless stainless U-tubes is essential in strategically important and critical fields-nuclear and petro-chemical machine building.
Utube heat exchangers Designed for high temperature applications,especially for steam condensing or hot oil systems.This model is selected when differential expansion makes a fixed tube sheet exchanger unsuitable and when conditions preclude a floating head type(HPF) selection.
Standard: ASTM A312,ASTM A269, ASME SA213, ASTM A249 ,ASME SA249, ASTM A789, EN10216-5 A106/A1016M

Initial Length: Maximum Lengths of 27000mm can be supplied on request.
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).


The basic Testing and processing:

1.High Pressure hydrostatic Test:Minimum:10 Mpa--25Mpa
2.Air Under Water Test After Bending
3.U Tube wall thickness Test
4.Eddy Current Test Before U bend Formed
5.Ultrasonic test before U bend Formed
6.Heat Treatment to stress relieved
7.Ball passing Test


The below sizes are those most frequently used,other sizes can be produced upon request.

Specialty and Advantages

1. Our company has been dedicated to producing stainless steel seamless pipe since 2003, owning complete producing technology and abundant managing experience.
2. The raw material such as mother tube, round bar we use is from Chinese biggest and well-known steel mill: Bao Steel and Yongxing Steel.
3. We have advanced NDT equipments for the tests such as Eddy Current test, Ultrasonic test, Hydraulic test and so on.
4. We have ISO 9001 certificate, and the Third Party Inspection Certificates such as TUV, BV, Lloyd’s, SGS, etc, also can be provided according to customers’ requirements,
5. Wooden case package which is strong and suitable for sea transportation is our main method to pack the pipes. And the economical packing method such as packed in bundles is also welcomed by some customers.
6. The tolerance control we use is +/-0.1mm on both inside and outside Diameter and Wall Thickness, which is much higher than international standard ASTM, DIN.
7. The surface condition is one of our main advantages: in order to meet different requirements for surface condition, we have annealing and pickling surface, bright annealing surface, OD polished surface, OD & ID polished surface etc.
8. In order to keep the inside surface of pipe clean and make it free from deburring, our company develops the unique and special technology --- Sponge Washing with high pressure.
9. We have complete after-sale service to deal with the problems in time.
