Guangzhou Flowtera Pipe Co., Ltd. is a specialized manufacturer of alloy steel pipes and stainless steel tubes. As a lead contributor to the global piping infrastructure since 2011, we have mastered the complexities of Grade 904L (UNS N08904)—a non-stabilized low carbon high alloy austenitic stainless steel.
Unlike standard 316L, 904L stainless steel contains high amounts of chromium (19-23%) and nickel (23-28%), with the crucial addition of copper. This makes it exceptionally resistant to strong reducing acids, such as sulfuric acid. Our factory utilizes precision cold-rolling and advanced annealing processes to ensure that every pipe exceeds ASTM A312 and EN 10216-5 standards.
The strategic importance of 904L Stainless Steel in modern engineering.
Across North America and Europe, the demand for Custom OEM 904L Stainless Steel Pipes is surging due to the aging chemical processing infrastructure. As industries transition to more aggressive chemical environments to increase efficiency, standard stainless steels are no longer sufficient.
In the Middle East and Southeast Asia, 904L is the gold standard for desalination plants and offshore oil rigs. Its resistance to chloride stress corrosion cracking (SCC) makes it the most reliable choice for warm seawater applications.
The burgeoning green hydrogen and lithium extraction industries require piping that can handle highly corrosive electrolytes. 904L pipes are now pivotal in the global shift toward sustainable energy solutions.
Bridging Chinese manufacturing efficiency with International Quality Standards.
Located in Guangzhou, we have direct access to the world's largest metal markets. This allows us to source the highest quality raw billets at competitive prices, a cost advantage we pass directly to our global clients.
Our engineering team can customize wall thickness (SCH 10S to SCH XXS), length, and surface finish (Mirror, Satin, Hairline) according to specific project drawings, ensuring a 1:1 fit for your local installation needs.
Every shipment undergoes Non-Destructive Testing (NDT), including Eddy Current and Ultrasonic testing. We provide full MTC (Material Test Certificate) according to EN 10204 3.1 or 3.2.
Guangzhou’s port infrastructure ensures that we can ship 904L pipes to any major port in the world (Dubai, Rotterdam, Singapore, Houston) within record timeframes, reducing your project downtime.
"Quality is not just a standard; it serves as the backbone of global safety."
Established in 2011, Flowtera began as a regional supplier of standard steel pipes for construction and mechanical applications. By 2015, the company expanded into high-performance alloy steel and stainless steel piping, investing in modern production lines for seamless and welded tubes. In 2019, Flowtera further strengthened its capabilities by introducing precision testing equipment and automated inspection systems, enabling compliance with international standards and demanding project requirements.
Our product range includes seamless alloy steel pipes, welded stainless steel tubes, duplex and super duplex pipes, as well as customized solutions for high-pressure, high-temperature, and corrosive environments. These products are widely used in industries such as oil and gas, petrochemical, power generation, shipbuilding, and construction.
The global steel industry is moving toward "High Performance & Low Maintenance." 904L stainless steel pipes embody this trend. While the initial investment is higher than 304 or 316, the lifecycle cost is significantly lower due to the extended service life in corrosive environments.
At Guangzhou Flowtera Pipe Co., Ltd., we are committed to sustainable manufacturing. By holding ISO 9001 certifications and meeting stringent ASTM, EN, and DIN standards, we ensure that our 904L pipes contribute to the safety and longevity of your global engineering and infrastructure projects.
