ASTM A179 Heat Exchanger Tubes Features:

ASTM A179 Heat Exchanger Tubes 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.

Top rated program customers’ requirements, we can analyze the ASTM A179 Heat Exchanger Tubes 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.
