A standard for the standardization of welded and seamless forged steel pipes covering high temperature or low pressure and high pressure.

ASTM A106 seamless pipes (also known as ASME SA106 pipes) are commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers and ships.

ASTM A500 is a standard specification published by ASTM International for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes.

ASTM A53 is a carbon steel alloy, which can be used as structural steel or for low-pressure pipelines.

Hot rolled seamless steel tube: hot rolling is related to the cold drawn, hot rolling is performed above the recrystallization temperature of the rolling.
