S30403 1.4306 Large Diameter Seamless Stainless Steel Pipe Annealed Pickled

Meet Your Strategic Metal Supply Partner

Established in 2006, MTSCO has specialized in stainless steel and nickel alloy pipe products for nearly two decades. We operate under a “Factory Complexes” model, collaborating closely with HUXIN PIPE, a major seamless pipe manufacturer. The factory possesses stable production capabilities for large-diameter seamless pipes. Our products hold certifications including ISO and PED, serving industrial projects worldwide. Leveraging a mature supply chain and engineering team, MTSCO delivers products with reliable delivery schedules.

Surface Condition

This product features an Annealed & Pickled surface finish. Annealing eliminates internal stresses, resulting in a more uniform and stable microstructure. This enhances the long-term operational safety of large-diameter seamless pipes. Pickling removes scale and surface impurities, improving corrosion resistance. This also facilitates subsequent welding and installation.

 Product Advantages

• Seamless pipe delivers high overall strength, ideal for large diameters

• Annealed and pickled condition ensures clean surface for easy installation and welding

• Strict adherence to ASTM A312 standards with traceable quality

• Custom lengths and specifications available to match project requirements
