Dexin's SCH 60 & SCH 60S seamless pipes bridge the gap between standard and extra-heavy wall schedules, engineered for applications requiring greater pressure integrity than SCH 40 but where the cost and weight of SCH 80 are excessive. Available in certified carbon, alloy, and stainless steels, they comply with ASTM A106, A335, A312, and API 5L standards. These pipes are the optimal choice for intermediate-pressure process lines, industrial utility headers, and structural columns where reliability, dimensional accuracy, and cost-efficiency are paramount.

SCH 60 seamless pipes represent an intermediate wall thickness schedule, offering a critical balance between pressure capacity and material economy. The S suffix in SCH 60S denotes pipes manufactured to stainless steel dimensional standards (ASME B36.19M). Constructed from certified materials including ASTM A106 Gr. B/C, A335 P-series alloys, and A312 stainless steels, these pipes are engineered for intermediate-pressure process systems, industrial utility mains, and demanding structural applications. Their optimized wall thickness provides enhanced safety margins over SCH 40 while avoiding the premium cost and weight of SCH 80, delivering superior value for performance-critical projects.
Thinnest wall in the common series. Best for low to moderate pressure, general service, and cost-sensitive applications where weight savings are desired.
The balanced choice. Approximately 50% thicker wall than SCH 40. Offers significantly higher pressure rating and corrosion allowance without the full cost/weight penalty of SCH 80.
Thickest common wall. Provides the highest pressure and mechanical strength. Used for high-pressure, high-temperature, or severe service but comes with higher material cost and weight.

Key questions and answers about SCH 60 seamless pipes, focusing on wall thickness, pressure performance, materials, and industrial applications.
SCH 60 refers to a pipe schedule with a thicker wall than SCH 40, providing higher pressure resistance and improved mechanical strength. It is commonly used in medium to high-pressure industrial piping systems.
SCH 60 seamless pipes are typically manufactured from carbon steel or stainless steel, in accordance with standards such as ASTM, EN, and API, depending on pressure, temperature, and corrosion requirements.
They are widely used in oil and gas pipelines, chemical processing systems, steam lines, power plants, and industrial fluid transmission where higher pressure capacity is required.
SCH 60 offers a balance between SCH 40 and SCH 80. It provides greater pressure resistance than SCH 40 while being lighter and more cost-effective than SCH 80 for certain medium-pressure applications.
Yes, SCH 60 seamless pipes are typically supplied with material test certificates (EN 10204 3.1), dimensional inspection reports, and optional third-party inspection documentation to meet international project requirements.
