ASTM A179/ASME SA179 Cold Drawn Seamless Carbon Steel Tube

ASTM A179/ASME SA179: Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser Tubes Standard: ASTM A179/ASME SA179
We are able to offer different grades of cold drawn seamless steel tubes, such as A179.
Manufacture: Seamless carbon steel pipes are made by cold drawing.

Introduction ASTM A179 or ASME SA179 cold drawn seamless carbon steel tube is applicable to tubular heat exchanger, condenser and other similar heat transfer equipment with the minimum wall thickness. This type of cold drawn seamless steel tube is widely used in chemical engineering, carbon treatment, oil refining, nuclear electric power generation, aviation, and so forth. STM A179 or ASME SA179 seamless carbon steel pipe is also used for manufacturing boiler water cold wall, economizer, reheater and steam pipe.

• ASTMA179/ASME SA179 standard is applicable for steel pipes with the outside diameter of 1/8in-3in. (32 mm to 76.2 mm). Our rolling technology has reached the international advanced level. JST is able to manufacture cold drawn seamless steel tubes with uniform wall thickness. Their tolerance is relatively smaller than the standard ones.
• When seamless carbon steel pipes are in the last cold drawing procedure, they will enter micro oxidization and non-oxidation heat treatment furnace for thermal treatment (Temperature is 1200℉ (650℃) or higher.). This makes the surface of cold drawn seamless steel tubes meet the no oxide scale standards, and guarantees smooth surface and stable performance.
• JST adopts professional hardness testing equipment to test the hardness of seamless carbon steel pipes. The Rockwell hardness value can not exceed 72 HRB.
• According to customers' requirements, we can analyze the cold drawn seamless steel tube and make its chemical composition meet standards. We choose one from 250 pipes or select one in a furnace to analyze. If the product analysis fails, then choose another two seamless carbon steel pipes. All elements of two steel pipes are in accordance with standards, and then these pipes can be delivered.
