Heat Exchanger Tube ASTM A179 Seamless Carbon Steel U Bend Tube Black Painting Surface
Seamless cold-drawn tube is usually used for tubular heat exchangers, condensers, and similar heat transfer apparatus. This tube shall be made by the cold drawn process. ASTM A179 black carbon steel U bend tube's minimum carbon content is 0.06%. This seamless carbon steel U bend tube's minimum tensile strength of 325 MPa, yield strength of 180 MPa.The minimum elongation of ASTM A179 seamless tube is 20%.
ASTM A179 Carbon Steel U Bend Tubes Applications:
A179 seamless steel pipe is widely used in industries such as petroleum, chemical, medical, food, light industry, machinery, instrument, include industrial pipeline and mechanical structure parts, etc.

ASTM A179 (ASME SA179) cold drawn steel tube:
This is an effective way of metal corrosion, the use of the main features are the following:
1. ASTM A179 cold drawn seamless pipe manufacturers with thick dense dense zinc layer covered in the cold drawn seamless tube surface, it can avoid cold drawn seamless tube matrix and any contact with the corrosion solution to protect the steel matrix from corrosion. In the general atmosphere, the surface of the zinc layer to form a layer of thin and dense zinc oxide surface, it is difficult to dissolve in water, so the steel matrix plays a protective role. If zinc oxide and other components of the atmosphere produce insoluble zinc salt, the anti-corrosion effect is more desirable.
2. With iron - zinc alloy layer, combined with dense, and with the unique anti-corrosion in the marine atmosphere and atmospheric atmosphere.
3. ASTM A179 cold drawn seamless pipe with a strong wear resistance due to the combination of solid, zinc - iron miscible.
4. Since zinc has good ductility, its alloy layer and steel base attached to a solid, so hot-rolled parts can be cold, rolling, drawing, bending and other molding without damage to the coating.
5. Hot-dip galvanized structural steel pipe, the equivalent of an annealing treatment, can effectively improve the mechanical properties of steel matrix to eliminate the steel forming welding stress, is conducive to the steel structure for turning.
6. The surface of cold drawn seamless pipe after hot galvanized is bright and beautiful.
7. Pure zinc layer is the most hot galvanized layer of galvanized layer, its nature is basically close to pure zinc, with ductility, so it is full of flexibility.
