13CrMo4-5 steel pipes are usually used as structural materials in high temperature and high pressure environments such as pressure vessels, boilers, and petrochemical equipment.

4130 is a common composite steel pipe with a very wide range of applications. It is mainly composed of iron, carbon and the addition of other alloying elements such as chromium, molybdenum and silicon to improve its mechanical properties and corrosion resistance.

ST37 carbon steel pipes are low carbon steel pipes that are commonly used in various industrial applications, including construction, engineering, and manufacturing.

ASTM A403 WP304 seamless elbow is often used in pipeline systems that require high corrosion resistance and pressure-bearing capacity, such as chemical, petroleum, natural gas, food processing and other industries.
