Product Spotlights
Hemaokang Steel (Shandong) Co., Ltd. is proud to offer premium 316L Stainless Steel Seamless Pipes specifically engineered for the demanding chemical industry. With an annual export value exceeding US$50 million and a dedicated team of 51-100 professionals, we ensure every pipe meets the highest standards of corrosion resistance and dimensional accuracy. Our ISO9001-certified facility in Liaocheng, Shandong, combines advanced manufacturing with rigorous quality control, delivering pipes that withstand aggressive chemicals, high temperatures, and pressure—making them the reliable choice for your critical pipelines.
Available in sizes 1/2", 3/4", 1", 2", and 3", these seamless pipes provide a smooth, uniform structure that eliminates weld seams, reducing the risk of leakage and corrosion. The 316L grade features low carbon content (≤0.03%), which enhances its resistance to intergranular corrosion after welding. Below are the key specifications and benefits:

- Exceptional Corrosion Resistance – The addition of 2-3% molybdenum in 316L provides superior resistance to chlorides, sulfuric acid, phosphoric acid, and other aggressive chemicals commonly found in chemical plants. This ensures long service life even in harsh environments.
- Seamless Construction – Unlike welded pipes, seamless pipes have no weld seam, eliminating weak points that can lead to stress corrosion cracking or leaks. The uniform grain structure guarantees consistent mechanical properties throughout the pipe.
- Low Carbon Content – The “L” grade (≤0.03% carbon) prevents carbide precipitation during welding, making these pipes ideal for chemical processing equipment that requires extensive welding without post-weld heat treatment.
- Excellent Mechanical Strength – With a minimum tensile strength of 485 MPa and yield strength of 170 MPa, these pipes handle high-pressure applications safely. They also maintain good toughness at cryogenic temperatures.
- Versatile Sizing Options – From 1/2-inch instrument lines to 3-inch main process lines, our range covers the most common diameters used in chemical plants. Custom schedules and lengths can be produced to meet specific project requirements.
- ISO9001 Quality Assurance – Every batch is tested for chemical composition, mechanical properties, dimensional accuracy, and hydrostatic pressure. Our in-house lab ensures compliance with ASTM A312 / ASME SA312 standards.
- Reliable Supply Chain – Based in the steel hub of Liaocheng, Shandong, we maintain ample inventory for quick shipment. Our export to over 10 regions (including North America, Europe, and Southeast Asia) demonstrates our global logistics capability.

Frequently Asked Questions (FAQ)
1. What is the difference between 316 and 316L stainless steel pipe?
316L has a lower carbon content (≤0.03%) compared to 316 (≤0.08%). This makes 316L more resistant to intergranular corrosion after welding, making it the preferred choice for chemical industry applications where welding is common.
2. Can these pipes be used for high-temperature applications?
Yes, 316L maintains good strength up to approximately 800°F (427°C). For higher temperatures, consider other grades like 310S. Always consult our technical team for specific temperature and pressure conditions.
3. Do you offer custom lengths or wall thicknesses?
Absolutely. We can customize lengths from 1 meter to 12 meters, and wall thicknesses can be adjusted based on schedule requirements (e.g., Sch 10S, 40S, 80S, or custom). Please specify your needs when ordering.
4. What is the typical lead time for an order?
For standard sizes (1/2" to 3") in Schedule 40S, lead time is approximately 7–15 days after order confirmation. Custom orders may require 20–30 days depending on quantity and specifications.
5. Do you provide third-party inspection?
Yes, we can arrange independent inspection by SGS, BV, or other agencies at your request. Our ISO9001 certification also ensures internal quality control procedures are followed.
6. How do you pack the pipes for export?
Pipes are bundled with steel straps, protected with plastic caps on ends, wrapped in waterproof material, and packed in sea-worthy wooden crates or steel frames suitable for container shipping. Custom packaging is available upon request.
7. Are these pipes suitable for food-grade or pharmaceutical applications?
316L is commonly used in food processing and pharmaceutical equipment due to its corrosion resistance and ease of cleaning. However, for specific hygienic standards (e.g., 3A, EHEDG), we recommend specifying a polished surface finish (e.g., 320 grit or finer) and proper passivation.
8. What is your minimum order quantity (MOQ)?
For most sizes, the MOQ is 100 meters. For smaller quantities, we recommend checking our stock availability or contacting our sales team for flexible solutions.
