ASTM A179/ASME SA179 Cold Drawn Seamless Carbon Steel Tube

ASTM A179/ASME SA179: Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser TubesStandard: ASTM A179/ASME SA179

We can easily offer different grades of cold drawn seamless steel tubes, such as A179.
Manufacture: Seamless carbon steel pipes are written by cold drawing.

Introduction ASTM A179 or ASME SA179 cold drawn seamless carbon steel tube is applicable to tubular heat exchanger, condenser different similar heat transfer equipment with the minimum wall depth. 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 cylinder.


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