Hemaokang Steel (Shandong) Co., Ltd. proudly presents our Carbon Seamless Steel Pipe ASTM A106 Gr.B Sch40 6m Length, specifically engineered for demanding oil and gas pipeline applications. As a company with an annual export value of US$50 million to US$100 million and a dedicated team of 51–100 professionals, we ensure every pipe meets rigorous quality standards. Our product combines strength, durability, and precise dimensions to deliver reliable performance in high-pressure environments.
Key features include:
- Material Excellence: Manufactured from premium carbon steel per ASTM A106 Grade B, offering excellent tensile strength and yield strength for high-temperature and high-pressure services.
- Precision Sizing: Scheduled 40 (Sch40) wall thickness provides balanced pressure rating and weight, ideal for oil and gas transmission lines.
- Standard Length: 6 meters (customizable lengths available upon request) to facilitate easy transportation and installation.
- End Finishing: Beveled ends for efficient welding, with optional threading or coupling as per project specifications.
- Surface Protection: Coated with black paint or varnished to prevent corrosion during storage and transit.

Advantages for Oil & Gas Pipeline Projects:
- High Pressure Resistance: Sch40 wall thickness ensures safe operation under typical oil and gas pressure ratings.
- Seamless Construction: No welded seams eliminate weak points, reducing risk of leaks and failures.
- Corrosion Resistance: Optional external coatings (FBE, 3LPE) available for buried or subsea pipelines.
- Easy Weldability: Carbon steel composition allows smooth field welding, saving installation time.
- Compliance: Manufactured under ISO9001 quality management system, with full traceability.
Our production process includes ultrasonic testing, hydrostatic testing, and dimensional inspection to guarantee compliance with ASTM A106 requirements. Each pipe is marked with grade, heat number, and dimensions for full traceability. We supply to major markets including North America, South America, Europe, Middle East, Africa, and Southeast Asia, with custom packaging and marking available.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between ASTM A106 Gr.B and API 5L Gr.B?
A: ASTM A106 Gr.B is a carbon steel pipe for high-temperature service, with tighter chemical and mechanical requirements. API 5L Gr.B is for line pipe in oil and gas. Our product meets both standards when required, but we primarily supply ASTM A106 Gr.B. -
Q: Can you supply other wall thicknesses besides Sch40?
A: Yes, we can produce Sch10, Sch80, Sch160, and custom schedules based on customer specifications. Please provide your requirements. -
Q: What lengths are available beyond 6m?
A: Standard random lengths are 6m, but we can supply 12m or custom lengths subject to order quantity. For shorter lengths, cutting service is available. -
Q: Do you offer third-party inspection?
A: Yes, we welcome inspection by SGS, BV, Lloyds, or other accredited agencies at the buyer's cost. Our factory supports on-site witness testing. -
Q: What is the minimum order quantity (MOQ)?
A: For stock sizes, MOQ is 1 ton per size. For non-standard sizes, please contact our sales team for MOQ details. -
Q: How is the pipe packed for export?
A: Pipes are bundled in steel straps, with plastic end caps and protective wrapping. Wooden cases are available for fragile coatings. Each bundle includes packing list and marks. -
Q: Can you provide material test certificates (MTC)?
A: Absolutely. Each shipment comes with MTC as per EN 10204 3.1 or 3.2, showing chemical and mechanical properties, heat treatment, and tests. -
Q: What is the lead time for a typical order?
A: For stock sizes, 7–15 days after deposit. For production orders, typically 20–30 days depending on quantity and specification.
