Product Advantages & Customer Benefits
- Seamless Construction: No welded seams means higher pressure tolerance and reduced risk of failure – ideal for high-temperature and high-pressure applications.
- Consistent Dimensions: Precise outer diameter and wall thickness ensure compatibility with standard fittings and easy installation.
- Excellent Weldability: Low carbon content and controlled chemistry allow for smooth welding without preheating in most cases.
- Long Service Life: Durable material resists corrosion, scaling, and wear, reducing maintenance costs over time.
- Fixed 6m Length: Standardized length simplifies cutting and reduces waste on job sites, saving labor and material costs.
- Customizable Options: Available with various surface treatments (black, galvanized, anti-corrosion coating) and end finishes (plain, beveled, threaded) upon request.

Frequently Asked Questions
Q1: What does ASTM A106 Gr.B mean?
A: ASTM A106 is a standard specification for seamless carbon steel pipe for high-temperature service. Grade B indicates a specific chemical composition and mechanical properties – it is the most common grade for industrial applications with good strength and weldability.
Q2: Is Schedule 40 suitable for high-pressure applications?
A: Yes, Schedule 40 provides a wall thickness that meets the pressure rating requirements for many industrial systems. For specific operating pressure, please consult our technical team – we can also supply Schedule 80 or other schedules if needed.
Q3: Can you provide custom lengths other than 6 meters?
A: Absolutely. While 6m is our standard fixed length, we offer custom cut lengths (e.g., 12m, or random lengths) per your project requirements. Please specify your needs when placing an order.
Q4: What certifications do you have for this product?
A: Our pipes are manufactured under ISO9001 quality management system. Additionally, we can provide mill test certificates (MTC) as per ASTM A106 requirements, including chemical and mechanical test reports.
Q5: How is the pipe surface treated?
A: By default, pipes come with a black (mill) finish. We can also offer galvanizing, anti-corrosion coating (FBE, 3LPE), or oiled surface based on your application and environmental conditions.
Q6: What is the minimum order quantity (MOQ)?
A: For standard sizes like 2-inch Schedule 40, our MOQ is typically 1 ton. For smaller quantities, please contact our sales team – we may accommodate sample orders.
Q7: Can this pipe be used for underground piping?
A: Yes, with proper external coating (such as FBE or 3LPE) for corrosion protection. Without coating, it is suitable for above-ground or indoor industrial piping. We can recommend the best coating option for your soil conditions.
Q8: What is the typical lead time?
A: For standard sizes and quantities, lead time is around 15–25 days after order confirmation. For large orders or special coatings, please allow additional time. We will confirm the exact schedule upon inquiry.
