ASTM A179 / A179M – 90a(2012) Standard Specification for Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser Tubes There are probably hundreds of different methods for packing a abrasion resistant pipe and Elbows, and most of them have merit, but there are two principles that are vital for any method to work prevent rusting and Sea transportation security.

ASTM A179 Tubes shall be made by the seamless process and shall be cold drawn. Heat and product analysis shall be performed wherein steel materials shall conform to required chemical compositions of carbon, manganese, phosphorus, and sulfur. The steel materials shall also undergo hardness test, flattening test, flaring test, flange test, and hydrostatic test.

Because of ASTM A179 grade’s temperature withstanding capabilities, it is applied to steel pipe of tubular heat exchanger, condensers and similar heat transfer equipment. Our ASTM A179 seamless tubes are used in sugar mills & distilleries, pumps and petrochemicals, cement and construction industries and steel plants. Sunny Steel can supply ASTM A179 steel tube from stock or from reputed steel mills. We also offer steel fabrication service where steel plates can go through processings like cutting, welding, bending, machining, pre-coating, pre-lined, beveling, or as you require.

This specification covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. Tubes shall be made by the seamless process and shall be cold drawn. Heat and product analysis shall be performed wherein steel materials shall conform to required chemical compositions of carbon, manganese, phosphorus, and sulfur. The steel materials shall also undergo hardness test, flattening test, flaring test, flange test, and hydrostatic test.

Features:

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.

Note:

  • Mill test certificates will be issued according to EN10204.3
  • All tubes shall be supplied as per applicable ASTM Specification.
  • The tubes Shall be Seamless and the testing shall be as per A 450 / A450M.
