ASTM A213 TP304 Stainless Steel Seamless U Bend Tube | Bright Annealed Heat Exchanger Tube

ASTM A213 / ASME SA213 TP304 Stainless Steel Seamless U Bend Tube

Product Overview

ASTM A213 / ASME SA213 TP304 Stainless Steel Seamless U Bend Tube is designed for heat exchangers, condensers, boilers and other industrial thermal equipment requiring stainless steel tubing with a U-bend configuration.

TP304 stainless steel provides good corrosion resistance and mechanical properties for a wide range of industrial heat-transfer applications. The seamless tube construction offers a uniform tubular structure, while the U-bend design allows the tube bundle to accommodate thermal expansion without requiring additional expansion joints.

YUHONG supplies TP304 seamless U bend tubes with customized tube dimensions, bend radius and leg length according to customer drawings, heat exchanger designs and project specifications.

U Bend Tube Design

The U-bend section is formed according to the required bend radius and heat exchanger configuration. Tube OD, wall thickness, center-to-center dimension, straight leg length and overall U-tube dimensions can be supplied according to customer drawings.

Proper control of the bending process helps maintain tube geometry and minimize deformation in the bend area. Post-bending heat treatment can also be arranged according to the applicable specification and project requirements.

Surface Finish Options

Bright Annealed
Bright annealing provides a clean and smooth metallic surface after controlled heat treatment. It is available when the project specification requires a bright surface condition and controlled oxidation during heat treatment.

Annealed & Pickled
Annealing followed by pickling can be supplied where a conventional stainless steel surface condition is acceptable.

Polished Surface
Mechanical polishing can be considered for applications requiring a smoother external surface, subject to tube dimensions and project requirements.

Applications

Heat Exchangers - TP304 seamless U-bend tubes are commonly used in shell-and-tube heat exchanger bundles. The U-tube configuration allows thermal expansion within the tube bundle and provides a compact heat-transfer arrangement.
Condensers - The tubes can be used in condenser equipment for industrial process systems where TP304 stainless steel is suitable for the operating medium and temperature.
Boilers and Heating Equipment - U-bend stainless steel tubes can be supplied for selected boiler, heater and thermal-processing equipment according to the required design conditions.
Chemical and Process Equipment - TP304 U-tubes are also suitable for selected chemical and industrial process equipment where corrosion resistance and heat-transfer performance are required.

Custom U Bend Tube Supply

U-bend dimensions can be manufactured according to customer drawings or heat exchanger specifications, including:

Tube outside diameter
Wall thickness
U-bend radius
Straight leg length
Center-to-center distance
Overall tube length
U-bend orientation
Tube end preparation

For large heat exchanger projects, dimensional requirements can be reviewed based on the customer's tube bundle drawings and technical specifications.

Inspection and Testing

Depending on the applicable standard and purchase specification, TP304 seamless U bend tubes can be supplied with:

Chemical composition testing
Mechanical property testing
Hardness testing where applicable
Hydrostatic or pneumatic testing
Eddy current testing
Ultrasonic testing where specified
Dimensional inspection
Visual and surface inspection
