ASTM A179/A179M-21 Al1060 FIn tube Embeded Type with Strong Protection Package

Yuhong Group has rich experience on the all kinds of fin tube. We are proundly to say our products are already exported to more than 55

countries. All types of fin tube for heat exchanger or other application is availble for us. We can also provide custom made size according to your

plan and provide the drawing for you before production.

ASTM A179 Finned Tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added to the surface of t

he ASTM A179 seamless heat exchange tube to increase the outer surface area (or inner surface area) of the heat exchange tube, so as to

achieve the purpose of improving the heat exchange efficiency.

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.
