Welcome to Hemaokang Steel (Shandong) Co., Ltd. – a professional manufacturer and exporter of high-quality seamless steel pipes. With an annual export value exceeding US$50 million and a dedicated team of 51–100 employees, we are proud to offer our ASTM A106 Gr.B Carbon Steel Seamless Pipe SCH40 6m Length, specifically designed for demanding oil and gas pipeline applications. Our products are manufactured under strict ISO9001 quality management systems, ensuring consistent performance and reliability. With global market presence across North America, South America, Europe, Asia, Africa, and Oceania, we are your trusted partner for critical infrastructure projects.
This pipe is produced using advanced seamless manufacturing techniques, which eliminate welded seams that can become weak points under pressure. The ASTM A106 Gr.B grade offers excellent strength and toughness, while the SCH40 wall thickness provides a balanced combination of durability and cost-effectiveness. Each pipe is cut to a standard 6-meter length for convenience in transportation and installation, but custom lengths are available upon request.
Key Features & Benefits
- Seamless Construction: No longitudinal or spiral welds; reduces risk of leakage and failure under high pressure.
- High Strength & Toughness: ASTM A106 Gr.B ensures minimum yield strength of 240 MPa and tensile strength of 415 MPa, suitable for elevated temperature services.
- SCH40 Wall Thickness: Optimized for standard pressure ratings; reduces material cost while maintaining structural integrity.
- 6m Standard Length: Facilitates handling, storage, and installation; compatible with common project requirements.
- Versatile Surface Finish: Available in black, varnished, or galvanized; anti-rust oil coating protects during transit.
- Customizable Options: Lengths, end preparations (plain, beveled, threaded), and packaging can be tailored to your specifications.
- Wide Application: Ideal for oil and gas pipelines, water injection, steam lines, and structural components in refineries, power plants, and chemical facilities.
- ISO9001 Certified: Rigorous quality control from raw material inspection to final testing ensures compliance with international standards.

Is this pipe suitable for high-temperature applications?
Yes, ASTM A106 Gr.B is specifically designed for high-temperature service, such as in boilers, superheaters, and refineries. It can withstand temperatures up to approximately 800°F (427°C) under proper conditions. -
Do you provide certificates of compliance or mill test reports?
Absolutely. We supply full mill test reports (MTRs) with each shipment, including chemical composition and mechanical properties, traceable to the heat number. Third-party inspection is also available. -
What surface finishes are available?
Standard finish is black (bare) with anti-rust oil coating. We also offer varnished, galvanized, or painted finishes depending on your project requirements. -
Can I order a small quantity for testing?
Yes, we accept trial orders. Minimum order quantity is flexible for sample requests. Please contact our sales team for details. -
How long does delivery take?
