Common models of seamless carbon steel pipes

Seamless carbon steel pipes are widely used in industries such as petroleum, chemicals, electricity, and metallurgy due to their excellent properties, including high-temperature resistance, corrosion resistance, and pressure endurance. These pipes are essential components in pipeline systems, offering strength and durability in various demanding environments.

Common Seamless Carbon Steel Pipe Model Classification

Types of Materials for Seamless Carbon Steel Pipes

Carbon Structural Steel

10#, 20#, 35#, 45#:

10# and 20#: Low-carbon steels with good plasticity and toughness, primarily used for fluid transport pipelines.

35# and 45#: Medium-carbon steels with high strength and hardness, commonly used for manufacturing mechanical and structural components.

Low-Alloy Steel

16Mn: This steel incorporates small amounts of alloy elements to enhance mechanical properties and corrosion resistance. It is widely used in high-pressure vessels, boilers, pipelines, and other critical applications.

Application Areas for Various Seamless Carbon Steel Pipes

10#, 20# Seamless Pipe
These pipes are commonly found in oil, natural gas, and similar industries, and they are also used as structural pipes in mechanical manufacturing fields.

35# Seamless Pipe
Ideal for high-pressure and ultra-high-pressure environments, such as high-pressure boilers and oil pipelines.

45# Seamless Pipe
