ASTM A213 TP304 1.4301 Stainless Steel SMLS U Bend Tube Boilers

 

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.
