ASTM A179 Carbon Steel Seamless U Bend Tube For Boilers And Heat Exchangers
Leave a message
What is ASTM A179 U Bend Tube material?
ASTM A179 specification covers seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and other heat transfer applications. ASTM A179 seamless carbon steel tube is supplied and produced by cold drawning method. It contains carbon, manganese, phosphorus, and sulfur. ASTM A179 Carbin Steel Seamless U Bend Tubes are widely used in boilers and heat exchangers. Heat Exchanger U Bend Tubes are usually applied in oil and gas plants, chemical and petrochemical industries, refineries, power generation plants and renewable energy plants.
Advantages of ASTM A179 seamless U Bend Tube
ASTM A179 Carbon Steel Seamless U Bend Tubes, also known as U Tubes, are widely used in heat exchanger applications. The key features of ASTM A179 U bend tubes are as belows:
High Ductility and Weldability: With a low carbon content (≤0.06%), ASTM A179 tubes offer excellent ductility and weldability. This facilitates precise U-bend forming and reliable joining in piping systems, especially for welded connections without compromising structural integrity.
Hydraulic Efficiency: Strict dimensional tolerances (outer diameter ±0.05mm, wall thickness ±0.03mm),The U-bend design enables smooth flow direction changes without additional welded elbows, reducing pressure loss and enhancing hydraulic efficiency.
High heat transfer efficiency: ASTM A179 U bend tubes allow fluid redirection in confined spaces without multiple fittings, making them ideal for compact industrial installations or modular equipment where space is limited.

Hydrostatictest
All U-tubes are subjected to a hydrostatic test after heat treatment.
The test time is not less than 5 seconds at the set pressure.
All tubes were blown dry and carefully cleaned after the test.
Measuring, cutting, deburring, cleaning
Accurately measure U-tubes according to relevant standards or customer requirements.
All pipes should be cut to length, deburred, and air dried to the inner wall.
Seal the ends with a plastic cap before packing.
Package
Use a strong, and depending on the distance to the destination, choose an open or sealed wooden case with a maximum weight of 8,000kg.
Both ends of the pipe are sealed with a plastic cap
Each elbow radius specification is vertically separated
Each row is separated by a chlorine-free plastic sheet every two meters
Each bundle of tubes is wrapped in plastic sheet
Customers can provide packaging drawings or Sandvik ready to package
The packing list should be packed in a plastic bag and placed in a wooden box for detailed review at the time of arrival - including all bend radii and pipe lengths.
