API is an acronym for the American Petroleum Institute and is considered the most authoritative and comprehensive principle in the oil and gas industry. API 5B and API 5CT are mainly used for oil casing. API 5CT oil casing can be divided into seamless steel pipe and welded steel pipe, welded steel pipe mainly refers to the straight seam steel pipe, large diameter oil casing is generally submerged arc welding straight seam steel pipe.
301 grade stainless steel is a common austenitic stainless steel with good corrosion resistance and high carbon content, and can be cold worked to various temperatures. Among stainless steels, 301 is the most easily strengthened steel by cold deformation. Cold deformation processing can improve the strength and hardness of steel, and retain sufficient plasticity and toughness. In addition, this steel has good rust resistance under atmospheric conditions, but its corrosion resistance in reducing media is poor, and its corrosion resistance in chemical media such as acid, alkali and salt is poor. Therefore, it is not recommended for corrosive environments.
316L stainless steel is an austenitic stainless steel metal alloy that contains nickel and molybdenum, making it corrosion resistant. 316L is a 316 low carbon grade. This grade is not affected by sensitization (grain boundary carbide precipitation). It is often used for large-gauge welded parts (approximately over 6mm). 316L stainless steel has higher creep, fracture stress and tensile strength than chromium nickel austenitic stainless steel at high temperature.
Galvanized pipe Galvanized steel pipe, also known as galvanized pipe, is divided into two kinds of hot dip galvanized and electro galvanized. The hot-dip galvanized layer is thick, the coating is uniform, the adhesion is strong, and the service life is long. Zinc is commonly used to galvanize or coat these metal tubes. The galvanizing process for steel pipes involves immersing the metal pipe in a bath containing 450 degrees Fahrenheit molten zinc. After a few minutes, the hot-dip galvanizing process is complete.
