ASTM A671 specification nominally covers pipe 16 in. (405 mm) in outside diameter or larger and of 1/4 in. (6.4 mm) wall thickness or greater.

ASTM A335 is often called as chrome moly pipe because of the chemical contain of Molybdenum (Mo) and Chromium (Cr). Molybdenum increases the strength of steel and Chromium (or chrome) is the essential constituent of stainless steel.

Precision seamless pipe is a pipe material producing by a cold drawn process with high precision and high-quality finish.

20G and 2727SiMn alloy pipe is a pipe material with high strength and corrosion resistance, which is widely used in petroleum, chemical, electric power, aerospace and other industries.
