Product Description

27SiMn alloy steel pipe 27simn seamless steel pipe=27 silicon manganese seamless steel pipe, is one of the materials of seamless steel pipe, the carbon content is between 0.24-0.32%, simn is listed separately because of the five elements (carbon C, silicon Si , manganese Mn, phosphorus P, sulfur S), the highest content of silicon manganese is about 1.10-1.40%.


27SiMn seamless steel pipe is a high-strength, low-alloy structural steel with good weldability, plasticity and toughness. It is usually used in high-pressure boilers, petrochemical equipment, shipbuilding, oil and gas pipelines, machining and other high-strength, low-alloy structural engineering and other fields.

1. Oil drilling: In the oil drilling industry, 27SiMn seamless steel pipes are used to transport oil and natural gas in oil wells, and can still maintain their strength and toughness under difficult working conditions.

2. Chemical industry: 27SiMn seamless steel pipe material is widely used in the chemical industry as a pipeline for transporting liquid chemical reagents.

3. Ship construction: High-strength and corrosion-resistant materials are required in ship construction. 27SiMn seamless steel pipes meet these requirements and can be used to manufacture various fittings and pipes for ships.

4. Infrastructure construction: Due to the high strength and toughness of 27SiMn seamless steel pipe, it is widely used in the construction of large infrastructure such as highways and bridges.
