Hemaokang Steel (Shandong) Co., Ltd. is proud to present our high-quality Carbon Steel Seamless Pipe ASTM A53 Gr.B Schedule 40 20 ft Length, specifically designed for rigorous construction applications. With over US$50 million in annual export value and a dedicated team of 51–100 professionals, we ensure every pipe meets the highest standards of durability and performance. Our seamless pipe offers superior strength and uniformity, making it a reliable choice for structural, mechanical, and pressure-related projects across North America, South America, Europe, Asia, and beyond.
This product is manufactured in strict compliance with ASTM A53 Gr.B specifications, ensuring consistent chemical composition and mechanical properties. The Schedule 40 wall thickness provides an optimal balance of strength and weight, while the 20-foot length minimizes weld joints and reduces installation time. Whether you need black plain-end pipes for welding or galvanized options for corrosion resistance, our flexible production capabilities can meet your exact requirements.
Backed by our ISO9001-certified quality management system, each pipe undergoes rigorous testing including hydrostatic, bend, and flattening tests. Our commitment to quality and timely delivery has earned us trust from clients in over 15 countries. Choose Hemaokang Steel for pipes that combine performance, consistency, and value.
Product Features & Technical Specifications
- Seamless Manufacturing: No welded seams ensure uniform strength and eliminate weak points, ideal for high-pressure and structural applications.
- ASTM A53 Gr.B Compliance: Meets the standard for carbon steel pipes used in mechanical and pressure applications, with minimum yield strength of 35,000 psi (240 MPa) and tensile strength of 60,000 psi (415 MPa).
- Schedule 40 Wall Thickness: Provides a strong, durable wall suitable for a wide range of construction loads, with standard dimensions per ANSI B36.10.
- 20 ft Length (6.1 m): Reduces the number of joints and fittings, speeding up installation and lowering overall project costs.
- Versatile Surface Options: Available in black (plain, varnished, or oiled) or hot-dip galvanized for enhanced corrosion resistance in outdoor or humid environments.
- Wide Size Range: Outer diameters from 1/2" to 24" (DN15 to DN600) are available, with custom lengths and end finishes (plain, beveled, threaded) upon request.
- ISO9001 Certified Quality: Every pipe is produced under strict quality control, including chemical analysis, mechanical testing, and non-destructive inspection.

Frequently Asked Questions (FAQ)
Q1: What is the difference between seamless and welded pipe for construction?
A: Seamless pipe is manufactured without a longitudinal weld seam, providing uniform strength and better pressure resistance. It is preferred for structural applications where weld integrity is critical, while welded pipe is more economical for non-critical uses.
Q2: Can this pipe be used for underground water lines?
A: Yes, the ASTM A53 Gr.B Schedule 40 pipe is suitable for underground water lines when properly coated or galvanized. We recommend galvanized finish for enhanced corrosion resistance in soil environments.
Q3: What end finishes are available?
A: Standard ends are plain (square cut). Beveled ends for welding and threaded ends for fittings are available upon request. Custom end preparations can be made to match your project specifications.
Q4: Do you provide third-party inspection reports?
A: Yes, we can arrange third-party inspection by SGS, BV, or other accredited agencies at your request. Our own mill test certificates are included with every shipment.
Q5: What is the minimum order quantity (MOQ) for this pipe?
A: The MOQ for standard sizes is typically 1 ton (approx. 10–20 pieces depending on diameter). For non-standard sizes or special coatings, MOQ may be higher. Please contact our sales team for details.
Q6: How do you ensure the pipe meets ASTM A53 Gr.B requirements?
A: Our production process is strictly controlled under ISO9001. We perform chemical analysis, tensile tests, flattening tests, hydrostatic tests, and dimensional checks on each batch. Certificates of compliance are issued with every order.
Q7: Can you supply pipes longer than 20 ft?
A: Yes, we can produce random lengths (17–24 ft) or custom lengths upon request. However, standard 20 ft length is the most popular for construction due to ease of handling and transportation.
Q8: What is the typical lead time for shipment?
A: For standard sizes in stock, lead time is 7–15 days. For custom orders, it may take 15–30 days depending on quantity and complexity. We maintain a large inventory to ensure fast delivery.
