Stainless Steel Welded Pipes & Tubes – 304/316 Grade Manufacturer

Stainless steel welded pipes and tubes are essential components across various industries due to their strength, precision, and corrosion resistance. Though often mentioned together, stainless steel welded pipes and tubes serve slightly different applications, and understanding their structure helps in selecting the right product for your project.
Welded stainless steel pipes are manufactured by rolling stainless steel plates or strips into a cylindrical shape and then welding the seam longitudinally. They are typically used for conveying fluids and gases, and are measured by their internal diameter (ID). On the other hand, welded stainless steel tubes are fabricated in a similar manner but are measured by their outside diameter (OD) and are favored for structural, mechanical, and precision engineering applications where tighter tolerances are needed.
Both products are made from high-quality austenitic stainless steel grades such as 304, 304L, 316, and 316L, which offer exceptional durability, excellent weldability, and resistance to corrosion, heat, and chemical attack. These characteristics make them ideal for demanding environments like food processing, chemical plants, marine systems, and heat exchangers.
At USA Piping Solution, our ss welded pipes are produced using premium raw materials, ensuring dimensional accuracy and compliance with global ASTM/ASME standards. Whether you're sourcing for construction, pharmaceutical systems, or offshore projects, our stainless steel welded pipes and tubes provide a reliable, long-lasting solution.
