Hemaokang Steel (Shandong) Co., Ltd. is proud to present our premium Stainless Steel Pipe 304, designed to meet the rigorous demands of global industrial applications. As a trusted manufacturer with ISO9001 certification and annual export value exceeding US$50 million, we ensure every pipe delivers exceptional corrosion resistance, dimensional accuracy, and long-term reliability. This 2" Sch 40 pipe complies fully with ASTM A312 standards, comes with a comprehensive 1-year warranty, and is accompanied by a Material Test Certificate (MTC) for full traceability.
Our 304 stainless steel pipe offers excellent weldability, formability, and resistance to oxidation, making it ideal for use in chemical processing, oil and gas, water treatment, and construction industries. The Schedule 40 thickness provides a robust balance between strength and weight, suitable for moderate to high-pressure systems. With strict quality control at every production stage, we guarantee consistent performance and compliance with international standards.
Key Features & Benefits
- Material: Grade 304 stainless steel (0Cr18Ni9) – excellent corrosion resistance in most environments, easy to clean and maintain.
- Standard Compliance: Manufactured in accordance with ASTM A312 – ensures mechanical properties, chemical composition, and dimensional tolerances meet strict industry requirements.
- Dimensional Accuracy: 2" nominal diameter with Sch 40 wall thickness (3.91 mm) – precise tolerances for seamless installation and leak-free joints.
- Traceability: Each pipe is supplied with a Material Test Certificate (MTC) detailing chemical analysis, mechanical properties, and heat number.
- Warranty: 1-year warranty against manufacturing defects – gives you peace of mind and reduces replacement costs.
- Surface Finish: Annealed and pickled – smooth, clean surface free of scale and impurities, ready for welding or further processing.
- Versatility: Suitable for both high-temperature and low-temperature applications, as well as corrosive fluid handling.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between Schedule 40 and Schedule 80 pipe?
A: Schedule 40 has a thinner wall (3.91 mm) while Schedule 80 is thicker (5.54 mm) for the same 2" nominal size. Sch 40 is lighter and more cost-effective for moderate pressure applications. -
Q: Is the MTC (Material Test Certificate) provided for each pipe bundle?
A: Yes, a full MTC is issued per production lot, including chemical composition, mechanical properties, and heat treatment details. You can request a copy for each batch. -
Q: Can you supply pipes in random lengths or custom cuts?
A: Yes, we offer standard 6m lengths and can cut to specific lengths (e.g., 3m, 4m, 5.8m) upon request. Custom cutting is available with additional charges. -
Q: What is the expected lead time for a 20-foot container?
A: Typically 15–25 days after order confirmation, depending on quantity and production schedule. Rush orders can be accommodated for an expedited fee. -
Q: Does the 1-year warranty cover all defects?
A: The warranty covers manufacturing defects such as pinholes, cracks, or dimensional deviations. It does not cover damage caused by improper installation, misuse, or corrosive environments beyond the material's specification. -
Q: Are these pipes suitable for underground water supply lines?
A: Yes, 304 stainless steel is resistant to corrosion from soil and water, but for highly aggressive soil conditions, we recommend wrapping or using a heavier grade like 316. Our technical team can advise based on your project details. -
Q: What payment terms do you accept?
A: We accept T/T, L/C, and other negotiable terms for confirmed orders. A 30% deposit is usually required, with the balance before shipment. -
Q: Do you provide samples for testing?
A: Yes, sample pipes (short lengths) are available for freight cost only. We can also provide sample certificates before bulk production.
