Hemaokang Steel (Shandong) Co., Ltd., established in 2025 with an annual export value of US$50-100 million, proudly presents our 316 Stainless Steel Pipe, 2 Inch Sch 80, 6m, Seamless, ASTM A182, Passivated Surface. As a professional manufacturer located in Liaocheng, Shandong, China, we combine advanced production technology with rigorous quality control to deliver pipes that meet the highest industry standards. Our product offers exceptional corrosion resistance, high strength, and a smooth, clean surface, making it the ideal choice for demanding environments such as chemical processing, marine engineering, and oil & gas applications. With ISO9001 certification and a global presence across North America, Europe, Asia, and beyond, we ensure reliable supply and consistent quality for every order.
Key Product Features & Benefits
- Superior Corrosion Resistance – Grade 316 stainless steel contains molybdenum, providing enhanced resistance to chlorides, acids, and harsh chemicals. Ideal for coastal, marine, and industrial environments.
- Seamless Construction – No welded seams means higher pressure capacity, uniform wall thickness, and reduced risk of leakage. Perfect for high-pressure applications.
- Schedule 80 Wall Thickness – Thicker walls (approx. 5.49mm for 2" Sch 80) offer greater mechanical strength and durability, suitable for heavy-duty piping systems.
- ASTM A182 Compliance – Manufactured to the strict ASTM A182 specification for forged or rolled alloy and stainless steel pipe flanges, fittings, and other components. Ensures dimensional accuracy and material traceability.
- Passivated Surface – A controlled chemical treatment removes free iron and contaminants, forming a passive oxide layer that maximizes corrosion resistance and extends service life.
- 6-Meter Standard Length – Convenient length for most industrial installations, reducing the need for joints and welding. Custom lengths available upon request.
- Versatile Applications – Suitable for use in chemical processing, oil & gas refineries, pharmaceutical equipment, food & beverage, pulp & paper, desalination plants, and structural components.
- Excellent Weldability & Formability – Despite being seamless, the pipe can be easily welded, bent, and fabricated using standard techniques.

Frequently Asked Questions
1. What is the difference between seamless and welded stainless steel pipe?
Seamless pipe is manufactured without a weld seam, offering higher pressure ratings and uniformity. Welded pipe has a longitudinal seam and is generally more economical for lower-pressure applications. Our 316 seamless pipe is ideal for critical service where integrity is paramount.
2. Why is passivation important for stainless steel pipes?
Passivation removes free iron and surface contaminants, enhancing the natural chromium oxide layer. This improves corrosion resistance, especially in chloride-rich environments, and extends the pipe's lifespan.
3. Does this pipe meet NACE MR0175 / ISO 15156 for sour gas service?
While our standard 316 stainless steel pipe is not specifically certified for NACE MR0175, it can be supplied with additional testing or material selection as per your requirements. Please contact us for customized solutions.
4. What are the typical tolerances for outside diameter and wall thickness?
Per ASTM A182, the tolerances are: OD ±1% (max 0.5 mm), wall thickness ±12.5% for Sch 80. Our production aims for tighter tolerances upon request.
5. Can you provide mill test certificates (MTC / EN 10204 3.1)?
Yes, we supply full mill test certificates with traceability to the heat number. This is standard for our ISO9001 quality system.
6. What is the minimum order quantity (MOQ)?
Our standard MOQ is 1 ton (approx. 40 pieces of 6m 2" Sch 80 pipe). Smaller quantities are negotiable for sample orders or repeat customers.
7. How is the pipe packaged for export?
We pack pipes in bundles with steel straps, waterproof wrapping, and protective end caps. Wooden crates or seaworthy plywood cases are available at extra cost.
8. What is the lead time for delivery?
For stock sizes, lead time is 7-10 days after order confirmation. For special lengths or large quantities, please allow 20-30 days depending on production schedule.
