Stainless Steel 304 Welded Pipes are designed for rigorous applications, emphasizing strength, anti-corrosion properties, and the malleable nature of welding. Created from high-quality Austenitic Stainless Steel, the Stainless Steel 304 Welded Pipes are highly effective for mild as well as more severe applications. Containing approximately 18% Chromium and 8% Nickel, this particular grade has successfully resisted oxidation and chemicals while retaining excellent welding properties. Due to these distinctive characteristics, Stainless Steel 304 Welded Pipes is mostly recommended to be made use of in the chemical industry, the oil and gas industry, the food industry, the pharmaceutical industry, the drinking water industry, as well as the structural application to some extent. They are manufactured to the following specifications, ASTM A312 TP304, ASTM A358, and ASME SA312 as well as a range of size requirements in terms of diameter, wall thickness, and finish.
At Metinox Overseas, Stainless Steel 304 Welded Pipes are manufactured with innovative welding processes and quality checks to cater to global standards and demands for projects. The pipes undergo rigorous checks and verification for reliability and long-lasting performance as per their PMI test, size verification, and surface finish checks.

The Stainless Steel 304 Welded Pipes are made following an effective plan, which guarantees strength, precision, and conforms to international regulations. This is how it is done:
Stainless Steel 304 Welded Pipes are very effective in various industries since it offers high resistance to corrosion, high strength and flexibility. They are favored in a number of applications because of their capacity to endure in the seemingly tough conditions:
Best used in ferrying corrosive chemicals, acids and alkalis in chemical processing plants due to their ability to withstand chemical attack and high temperatures.
Applied in pipelines, refineries and processing facilities where they are needed to take high durability and sour gas and mild corrosive conditions.
They are commonly used in sanitary piping systems, food processing systems and breweries because of their sanitary qualities and carelessness to clean.
Applied in the production and cleanroom piping systems where purity, anticorrosion, and transport without contamination are of great importance.
Used in water and wastewater treatment of piping systems that need corrosion resistance and durability.
Applied in architectural buildings, handrails, decorative pipes, etc., where corrosion resistance are needed as well as aesthetic finishing.
Applicable in exhaust, fuel lines and structural parts that need to be lightweight and corrosion resistant.
It has been used in heat exchangers, condensers, and cooling systems where it is needed to have high temperature and be resistant to corrosion.
Choose Metinox Overseas � Your Reliable SS 304 Welded Pipe Supplier & Exporter.
Let us support your projects with quality, precision, and performance.
The SS 304 welded pipe is a corrosion-resistant stainless steel pipe made by welding high-quality SS 304 strips or plates, commonly used in industrial and sanitary applications.
Welded pipes are made by joining steel strips, while seamless pipes are made by extrusion; welded pipes are more cost-effective, while seamless pipes handle higher pressure.
If you want to choose between SS 304 and SS 316 welded pipes, choose SS 304 for general corrosion resistance and cost-effectiveness on the other hand select SS 316 for stronger resistance to chlorides, acids, and harsh marine environments.
Yes, SS 304 welded pipes resist rust, oxidation, and most chemicals, making them suitable for many industrial applications.
Yes, their hygienic surface, corrosion resistance, and easy cleaning make them ideal for food, beverage, and pharmaceutical piping systems.
