| High Light | Cold-Drawn Seamless U Bend Tube ，Low Carbon Steel U-Tube ，Heat Exchanger U-Shaped Tube | ||
ASTM A179 U-bend tubes are seamless, cold-drawn low-carbon steel tubes that are formed into a U-shape for shell-and-tube heat exchangers, condensers, coolers, and similar heat-transfer equipment. The base tube is produced by the seamless process and cold drawing, then bent to the required radius/leg length with strict control of dimensional stability and surface condition.
Product type: U-bend (U-tube) for heat exchangers
Base material / standard: ASTM A179 / A179M (often referenced as SA179 for similar procurement language)
Manufacturing route: Seamless → cold drawn → U-bending (per drawing)
Typical base tube OD range (ASTM A179 scope): 1/8" to 3" (3.2–76.2 mm)
Key U-bend parameters (customized):
Bend radius (CLR), leg length, tangent length, straight length, end finish
Controlled ovality and wall thinning at the bend (measured and reportable)
Excellent heat-transfer suitability: smooth OD/ID, consistent wall, stable geometry from cold-drawn tubing
Reliable forming performance: low-carbon chemistry supports bending, expanding, and rolling operations commonly required for tube-to-tubesheet assembly
Quality verification: chemistry control + mechanical testing + typical tube tests (e.g., hardness/flattening/flaring/hydrostatic or NDT options per order)
How do you control wall thinning and ovality at the U-bend?
We control bending tooling, lubrication, and forming parameters, and can provide bend-area measurements (ovality and wall-thinning). Many buyers specify limits (e.g., ovality and thinning caps) for U-tubes; we can manufacture and inspect to your project criteria and supply inspection records.
What inspections and documentation will I receive?
We provide full traceability by heat/lot and Mill Test Certificate (EN 10204 3.1 available upon request), plus compliance with required tests under ASTM tube requirements (chemical/product analysis and mechanical verification; hydrostatic or nondestructive testing when specified).
How do you prevent contamination and shipping damage (critical for heat exchangers)?
We follow controlled finishing and packing practices (cutting/deburring/cleaning, end caps/sealing, and export packing) to protect tube ends and internal cleanliness during transport and storage.
