ASTM A213/ASME SA213 TP444 SEAMLESS STAINLESS STEEL U BEND HEAT EXCHANGER TUBE

 

 

Overview

 

Features U' bending is done by cold working process.
U' bending is done to the required radius as per customer drawings.
The bend portion and six inch leg is stress relieved by resistance heating.
Inert gas (Argon) is passed through it at the required flow rate to avoid oxidation in ID.
The radius is checked for its OD and wall thinning with the recommended specification.
The physical properties and micro-structure is checked at three different position.
Visual inspection for waviness and cracks is done with Dye Penetrant Test.
Each tube is then hydro tested at the recommended pressure to check for leakage.
Cotton ball test is done to check the ID cleanliness of the tube.
Thereafter pickled, dried, marked and packed.

 

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.
