Products Description
The ASTM A179 / ASME SA179 Seamless Tubes has similar grades and standards like ASTM A179/ A179M. It is viable in types like seamless / cold drawn / hot drawn etc. This tube product is available in custom-made size, diameter, and thickness. The Carbon Steel A179 Heat-Exchanger Tube is strictly subjected to various tests in order to ensure the quality of the product. This grade of the tube is packed in wooden box or case in order to avoid external damage during the last stage of production. What's more, these tubes are used in various industrial applications and are available in market leading prices.
These Seamless Tube mainly find applications in Pressure Vessels, Cryogenic Pressure Vessels, High pressure Equipments, Tube Sheets of Heat Exchangers, Boilers, Air Pre Heater, Finned Tubes, Air Cooler Tubes, etc. They are used in Industries like Refineries, Power Plants, Steel Plants, Chemical Factories, Fertilizer plants, and Ship Building etc.
U Tubes are manufactured after the Straight Tubes are manufactured. The Bending is done in Cold State on an Automatic U Bending Machine. To ensure that wall thinning and diameter ovality are kept in control, bending of tubes Is done with a mandrel inserted in the tubes. Furthermore the U - Bend portion of the U-Tube is Stress Relieved in controlled conditions and cycle to give longer life.
The U bent tubes are finally 100% Tested for Hydrostatic Leak Test and then finally DP tested. These tubes are vulnerable to getting damaged in transit and hence are required to be handled with care. We ensure this by packing tubes in specially designed steel frames. These frames are fit into the wooden box o further ensure ety of the tubes.

A179/SA179 U Bend Tube Principle
U-tubes are usually used to exchange heat in process fluids with large radiators. The fluid is pumped out through a pipe, through a U-Junction, and then flows back along a pipe parallel to the inflow line.
Heat is transferred to the wrapping material through the wall of the tube. This design is used in industrial applications where many U-tubes can be poured into oil containers with high heat capacity.
A179/SA179 U Bend Tube Advantages
