ASTM A213 TP304L Austenitic Stainless Steel Seamless U Bend Tube
YUHONG Group deals with Austenitic Stainless Steel, Nickel Alloy Steel(Hastelloy , Monel, Inconel, Incoloy)seamless and welded pipe and tube already more than 32 years, every year sell more than 80000 tons of steel pipe and tube.
A213 TP304L seamless U-bend tubes are specialized components used
primarily in heat exchangers, pressure vessels, and other
applications requiring high corrosion resistance and good
mechanical properties at elevated temperatures.
Characteristics
1. Corrosion Resistance: TP304L exhibits excellent resistance to a
wide range of corrosive environments, including many organic and
inorganic chemicals.
2. Temperature Resistance: This material maintains its strength and
mechanical properties at elevated temperatures, making it suitable
for high-temperature applications.
3. Weldability: The low carbon content enhances the weldability of
TP304L, making it a preferred choice for fabrication processes that
involve welding.
4. Mechanical Properties: TP304L has good tensile strength and
ductility, which allows it to withstand various mechanical stresses
in operational environments.
U-Bend Configuration
Shape: The U-bend design allows for efficient heat transfer in
applications such as heat exchangers, where space is limited, and
effective fluid flow is crucial.
Manufacturing: The seamless U-bend tubes are manufactured without
any welded seams, which enhances their structural integrity and
reduces the risk of leaks or failures under pressure.
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.
