The core advantages of SCH XS carbon steel pipe is reflected in their structural strength and pressure bearing capacity: compared to standard wall thickness (STD) steel pipes, their wall thickness increases by 30% -50%. According to the formula (OD-T) x T x 0.02466, carbon steel pipe with the same outer diameter have a higher weight, which means they can withstand higher working pressures.
High Voltage and High Strength
Pressure bearing capacity: Due to the increase in wall thickness, SCH XS carbon steel pipe is suitable for high-pressure conditions (such as petroleum, chemical, and power station pipelines), and its resistance to internal pressure is significantly higher than SCH 40.
Resistance to mechanical stress: more resistant to external impacts, bending, and vibration.
Corrosion Resistance
Thickened walls can extend the service life in corrosive environments, such as chemical pipelines, especially in designs that require corrosion allowance (C.A).
High Temperature Applicability
The creep resistance at high temperatures is superior to that of thin-walled pipes, making it suitable for steam pipelines and thermal systems.
Stability
High uniformity of wall thickness reduces the risk of deformation caused by processing or welding.
ASTM A106B, as an important material standard for American standard seamless steel pipes, is widely used in the field of industrial pipelines. Its chemical composition is mainly composed of carbon and manganese as alloying elements, with sulfur and phosphorus content strictly controlled below 0.035%, ensuring that the material has good welding and cold working properties.
Chemical Composition
| CHEMICAL | LIMITS | C | Mn | P | S | Si | Cr | Mo | Ni | Cu | V |
| ASTM A106B | MIN | 0.29 | 0.10 | ||||||||
| MAX | 0.30 | 1.06 | 0.035 | 0.035 | 0.40 | 0.15 | 0.40 | 0.40 | 0.08 |
In terms of mechanical properties, ASTM A106B has a tensile strength of not less than 415MPa, a yield strength of ≥ 240MPa, an elongation rate of over 20%, and can maintain structural stability in high temperature and high pressure environments.
Mechanical Properties

The significant advantage of this material lies in its balance between high temperature tolerance and economy, exhibiting stability within the conventional operating temperature range and suitable for working conditions such as steam pipelines and heat medium transport pipelines; Compared to alloy steel pipes, it has lower production costs and obvious cost-effectiveness advantages, making it the preferred material for conventional high-pressure pipeline projects.
With excellent high pressure resistance, SCH XS carbon steel pipes play a key role in multiple industrial fields:
Oil and Gas Industry: used for high-pressure gathering and transmission pipelines, wellhead casings, etc., capable of withstanding the formation pressure and medium erosion during oil and gas extraction
Chemical Production: as a connecting pipeline for high-pressure reactors and catalyst transportation pipelines, it is suitable for high-pressure transportation conditions of acid-base media
Power System: applied to boiler steam pipelines and high-pressure feedwater pipelines, meeting the operating environment requirements of high temperature and high pressure in thermal power plants
Municipal Engineering: providing stable structural support in high-pressure water transmission and sewage treatment pressurized pipelines to reduce leakage risks
From order confirmation to efficient response to finished product delivery, from material control to strict management of dimensional accuracy, Shanghai Zhucheng always protects customer trust with professional capabilities. In the future, the company will continue to deeply cultivate the field of American standard seamless pipes and provide better products and services to global customers.
