Our company is located in Cangzhou city, Hebei province, China. It's near Beijing and Tianjin. The transportation is convenient and the geographical location is superior. Welcome to our seamless steel pipe workshop.

Seamless steel pipes are an essential component in the construction industry, used for transportation and distribution of fluids and gases. They are manufactured through a process that involves piercing a solid steel billet to produce a hollow tube. Seamless steel pipes are known for their durability, strength, and resistance to high pressure and temperature. They are widely used in various applications such as oil and gas exploration, refineries, chemical processing plants, and power plants.

Thick-Walled Seamless Steel Pipes

Thick-walled seamless steel pipes are characterized by a large diameter and high wall thickness. They are used in applications that require high strength, such as oil and gas pipelines, pressure vessels, and hydraulic cylinders. They are also used in applications that involve high temperatures and pressure, such as boilers and heat exchangers.

The manufacturing process of thick-walled seamless steel pipes involves piercing a solid steel billet repeatedly until the desired diameter and wall thickness are achieved. They are then subjected to heat treatment to enhance their strength and durability. Thick-walled seamless steel pipes are available in various grades such as ASTM A106, ASTM A53, and API 5L.

Thin-Walled Seamless Steel Pipes

Thin-walled seamless steel pipes, on the other hand, have a smaller diameter and thinner walls. They are used in applications that require high precision, such as automotive parts, hydraulic systems, and precision instruments. Thin-walled seamless steel pipes are known for their excellent mechanical properties, high precision, and good surface finish.

The manufacturing process of thin-walled seamless steel pipes involves piercing a solid steel billet repeatedly until the desired diameter and wall thickness are achieved. They are then subjected to cold drawing or cold rolling to achieve their final dimensions and surface finish. Thin-walled seamless steel pipes are available in various grades such as ASTM A519 and EN 10305-1.

In conclusion, seamless steel pipes are an essential component in the construction industry, used for transportation and distribution of fluids and gases. They can be divided into thick-walled seamless steel pipes and thin-walled seamless steel pipes according to their different purposes. The choice of seamless steel pipes depends on the specific requirements of the application and the environment in which they will be used.
