Hemaokang Steel (Shandong) Co., Ltd. proudly presents our premium 304 Stainless Steel Pipe 2 Inch Schedule 40 Seamless 6 Meter Length – a reliable solution for demanding industrial piping applications. Manufactured in our state-of-the-art facility in Liaocheng, Shandong, China, this pipe combines superior corrosion resistance, high strength, and precision dimensions to ensure long-lasting performance in chemical, petrochemical, oil & gas, and construction environments. With ISO9001 certification and an annual export value exceeding US$50 million, we deliver consistent quality and global logistics support.
Our seamless 304 stainless steel pipe is produced using advanced hot-rolled and cold-drawn processes, ensuring a uniform wall thickness and smooth internal surface that minimizes pressure drop and reduces maintenance. The 2-inch nominal size (DN50) with Schedule 40 wall thickness (3.91 mm) offers an excellent balance of pressure rating and flow capacity, suitable for both low and high-pressure systems up to 1000 psi (depending on temperature). Each 6-meter length is cut precisely, with ends prepared for butt welding or threading as per your requirements.
Product Highlights
- Material Grade: 304 Stainless Steel (UNS S30400) – excellent corrosion resistance in oxidizing environments, suitable for water, chemicals, and food processing.
- Seamless Construction: No welded seams, reducing risk of leaks and improving mechanical integrity under cyclic loads.
- Schedule 40 Wall: Standard thickness for 2-inch pipe, delivering robust strength while maintaining cost efficiency.
- Standard Length: 6 meters (20 feet) – ideal for industrial piping layouts; custom lengths available upon request.
- Certification: ISO9001:2015 quality management system ensures consistent product performance.
- Finish: Annealed and pickled surface for clean, scale-free appearance and improved weldability.
- Compliance: Meets ASTM A312 / ASME SA312 specifications for seamless austenitic stainless steel pipe.

The seamless manufacturing process eliminates the risk of weld defects, providing a homogeneous structure that withstands thermal expansion and mechanical stress. Compared to welded pipes, our seamless 304 schedule 40 pipe offers superior burst pressure resistance and longer service life in corrosive environments. The 304 alloy contains 18-20% chromium and 8-10.5% nickel, forming a passive oxide layer that resists oxidation and scaling up to 870°C (1600°F) in intermittent service.
For industrial applications such as steam lines, gas distribution, chemical transfer, and structural supports, this pipe delivers consistent performance. Its smooth interior reduces friction losses, improving flow efficiency and energy savings. The 6-meter length minimizes the number of joints required, lowering installation costs and potential leak points.
Hemaokang Steel maintains a dedicated quality control team that conducts 100% dimensional inspection, hydrostatic pressure testing, and chemical composition analysis on every batch. Our ISO9001-certified processes ensure traceability from raw material to final product. We also offer custom beveling, threading, and cutting services to meet your exact project specifications.
With over 51-100 experienced employees and an annual export value ranging from US$50 million to US$100 million, we have the capacity to handle large-scale orders efficiently.

Frequently Asked Questions
-
What is the maximum operating temperature for this pipe?
304 stainless steel can be used continuously up to 870°C (1600°F) in oxidizing environments, but for pressurized applications, derating factors apply. For specific temperature limits, consult our engineering team. -
Can I get custom lengths shorter than 6 meters?
Yes, we can cut the pipe to any length between 1 and 6 meters at no extra charge for standard orders. Longer lengths (up to 12 meters) are also available upon request. -
What are the available end connections?
Standard ends are plain (beveled for butt welding). We can also supply threaded ends (NPT or BSPT) or grooved ends for mechanical couplings. Please specify your requirements. -
Is this pipe suitable for potable water systems?
Yes, 304 stainless steel is NSF/ANSI 61 certified for drinking water when properly processed. Our pipe meets the appropriate chemical composition standards, but we recommend verifying local regulations. -
How do you ensure the pipe is free from defects?
Every pipe undergoes hydrostatic testing at 1000 psi, eddy current inspection, and visual examination. We also provide a mill test certificate (MTC) with each shipment. -
What is the typical lead time for this product?
For standard 6-meter lengths, we maintain a stock of 500 tons. Delivery can be within 7-15 days after order confirmation, depending on quantity and destination. -
Can you provide samples before bulk order?
Yes, we offer free samples (up to 30 cm length) for quality evaluation. The buyer only needs to bear the shipping cost. Contact our sales team for details. -
What is the difference between Schedule 40 and Schedule 80?
Schedule 80 has a thicker wall (5.54 mm for 2-inch) and higher pressure rating, but is heavier and more expensive. Schedule 40 is sufficient for most industrial applications up to 1000 psi.
