ASTM A199/A199M standard specifies the minimum wall thickness, composition such as chromium-molybdenum and chromium-molybdenum-silicon, and production process requirements such as seamless and cold drawing.
The manufacturing process of A199 seamless steel pipe includes precision processes such as cold drawing, which ensures the accuracy and performance of the steel pipe.
GNEE is a professional exporter of ASTM A199 alloy pipes, supplying different grades of ASTM A199 pipes. For example, T4, T1, T2, T5, T11, T22 pipes. Its specifications range from a wide range of outer diameters from φ16 to φ159 mm, wall thickness from 0.6 to 18 mm, and length up to 12 meters1.
Before leaving the factory, A199 carbon steel pipes must undergo flattening test, expansion test, hardness test, flange test and hydrostatic test.
