Industry-standard SS 304 Sch 40 Pipes and Specialized Tubing
The global demand for SS 304 Sch 40 pipe thickness has reached unprecedented levels as industries prioritize longevity and corrosion resistance. "Schedule 40" is not just a measurement; it is the universal benchmark for medium-pressure applications, offering the perfect balance between wall thickness, weight, and structural integrity. From the petrochemical corridors of the Middle East to the high-tech pharmaceutical labs in Europe and North America, Stainless Steel 304 remains the "gold standard."
As a leading China SS 304 Sch 40 Pipe Manufacturer, we observe that "Schedule 40" thickness is the most sought-after specification for fluid transport. It provides sufficient wall thickness to handle significant internal pressures while remaining cost-effective for large-scale infrastructure projects. In Russia and the CIS regions (under the designation Компания), the demand is driven by extreme temperature variations where the austenitic structure of 304 stainless steel ensures zero brittleness even in sub-zero climates.
304 alloy contains 18% chromium and 8% nickel, providing an invisible oxide layer that prevents oxidation in diverse atmospheric conditions.
Sch 40 thickness offers a robust wall that resists physical deformation and maintains integrity during high-flow fluid transport.
Our pipes meet ASTM A312, ASME B36.19M, and EN 10217-7 standards, ensuring seamless integration into international projects.
OES Metal, established in 2014, is a famous professional steel company specialized in producing. Our factory is located in Wuxi, Jiangsu, with more than 100 employees and a 5000 square meter factory, capable of running platform processing equipment every day for manufacturing, cutting, packaging, and other work.
You will be impressed by our superior quality control services in technology, packaging, and delivery. Oes Steel has exported thousands of tons of high-quality STEEL to North America, South America, Gulf countries, Africa, CIS, and Southeast Asia. The products have been exported to more than 50 countries and regions.
The modern procurement officer is no longer satisfied with just a paper MTC (Material Test Report). Global buyers are now demanding real-time tracking of pipe thickness, chemical composition via XRF analysis, and ultrasonic testing (UT). At OES Metal, we leverage AI-driven inspection tools to ensure that every Sch 40 304 pipe leaves our Wuxi factory with zero defects.
Stainless steel is 100% recyclable. We are seeing a massive shift in procurement from "lowest price" to "lowest carbon footprint." Our manufacturing processes in China are evolving to reduce energy consumption, making our 304 pipes more attractive to ESG-compliant contractors in Europe and Asia.
In the Russian-speaking markets, the term "Компания" (Company) represents a partnership based on trust and technical expertise. We have customized our Sch 40 pipe thickness production to meet GOST equivalents (like 08X18H10), ensuring that our Chinese-manufactured steel fits perfectly into CIS-designed infrastructure.
When calculating "Schedule 40" thickness, remember that wall thickness varies with the Nominal Pipe Size (NPS). For example, a 2-inch Sch 40 pipe has a thickness of 0.154 inches, while a 10-inch Sch 40 pipe has 0.365 inches.
Standard Wall Thickness (ASME B36.10M / B36.19M)
| Nominal Pipe Size (NPS) | Outside Diameter (inch) | Sch 40 Wall Thickness (inch) | Weight (lb/ft) |
|---|---|---|---|
| 1/2" | 0.840 | 0.109 | 0.85 |
| 1" | 1.315 | 0.133 | 1.68 |
| 2" | 2.375 | 0.154 | 3.66 |
| 4" | 4.500 | 0.237 | 10.80 |
| 8" | 8.625 | 0.322 | 28.58 |
| 12" | 12.750 | 0.406 | 53.57 |
In Australia and the USA, SS 304 Sch 40 pipes are the primary choice for dairy and brewery lines due to their "food-grade" safety and easy-to-clean surfaces.
In Southeast Asia (Vietnam, Philippines), these pipes are used in municipal water systems where humidity and salt air would corrode carbon steel within years.
Used for cooling water lines in power plants across the CIS and Middle East, where durability and high thermal conductivity are essential.
