Hemaokang Steel (Shandong) Co., Ltd., established in 2025, has rapidly grown into a reliable supplier of high-quality stainless steel products. With an annual export value of US$50 Million to US$100 Million, we serve clients across North America, South America, Europe, Asia, Africa, and Oceania. Our ISO9001 certified factory in Liaocheng, Shandong, ensures every product meets rigorous quality standards. Introducing our 316L Stainless Steel Seamless Pipe 6 Inch Schedule 10S 180 Grit Polish — a premium solution for demanding industrial applications requiring superior corrosion resistance and a smooth, hygienic finish.
This pipe is manufactured from low-carbon 316L stainless steel, providing excellent resistance to chlorides, acids, and harsh environments. The seamless construction eliminates weld seams, offering higher pressure integrity and uniformity. The 180 grit polished surface ensures a mirror-like finish, reducing particle adhesion and making it ideal for clean rooms, food processing, and pharmaceutical lines. Each pipe is produced in accordance with ASTM A312 / ASME SA312 standards, guaranteeing dimensional accuracy and mechanical properties.

The 180 grit polish is achieved through a multi-stage mechanical buffing process, resulting in a smooth, non-porous surface that minimizes contamination. This makes our pipe an excellent choice for sanitary applications such as dairy, beverage, and pharmaceutical industries. The seamless structure also ensures no weak points, reducing the risk of leaks under pressure or thermal cycling.
