ASTM A312 is a standard specification for seamless, welded, and heavily cold-worked austenitic stainless steel pipes. This norm covers several grades of stainless steel pipes for high-temperature and general corrosive service. It is widely used in the chemical processing, petrochemical, food processing, and pharmaceutical industries, as well as in construction and other applications.

The ASTM A312 standard covers pipes with diameters ranging from 1/8″ to 30″ and thicknesses from SCH 5S to SCH XXS. The pipes can be either seamless or welded and can be produced using several manufacturing processes, such as hot finished, cold finished, or hot rolled.

The standard requires that the pipes be made of austenitic stainless steel, which is a type of steel that contains high levels of nickel and chromium. This gives the steel excellent corrosion resistance and makes it suitable for use in harsh environments, such as those found in the chemical and petrochemical industries.

The ASTM A312 norm specifies several different grades of austenitic stainless steel, including TP304, TP304L, TP316, TP316L, TP321, TP347, and TP348. Each of these grades has specific chemical and mechanical properties that make it suitable for different applications.

In addition to the basic requirements for the manufacturing process and the materials used, the ASTM A312 norm also specifies requirements for dimensions, tolerances, and testing. For example, the norm requires that the pipes be inspected visually and that they be subjected to several types of non-destructive testing, such as ultrasonic testing and eddy current testing.

Overall, the ASTM A312 norm is an important standard in the stainless steel industry, providing guidelines for the manufacture and testing of austenitic stainless steel pipes. By ensuring that these pipes meet specific requirements for materials, manufacturing, and testing, the standard helps to ensure that they are safe and reliable for use in a wide range of applications.

Cold-rolled steel pipe.
Cold-rolled steel is a more finished product that not only looks nicer, having a more finished surface but is also more durable than is hot-rolled steel. This steel is created by further processing hot-rolled steel. Cold-rolled steel is superior in performance compared to hot-rolled steel but may be harder to manipulate than hot-rolled steel due to a higher carbon content.

Hot-rolled steel pipe.
A hot-rolled steel coil is formed almost exactly as its name implies: the steel is rolled at a high temperature, which makes the steel easier to manipulate, resulting in a product that is easier to work with. Because there is less processing involved in the manufacturing of hot-rolled steel, it is typically much less expensive than cold-rolled steel coils.

Stainless steel pipe is widely used in industry, construction, home, medical and other fields, such as bridges, high-speed railways, kitchen utensils, medical equipment and so on. It not only has excellent corrosion resistance, wear resistance, high strength and other characteristics, but also has a beautiful and generous appearance, which is the ideal choice for many high-end products.
