Hemaokang Steel (Shandong) Co., Ltd. is a reliable manufacturer and supplier of high-quality steel pipes, established in 2025 with an annual export value of US$50 Million – US$100 Million. Our ERW Carbon Steel Pipe ASTM A53 Grade B SCH40 6m Length is specifically designed for demanding oil and gas pipeline applications, ensuring superior strength, durability, and corrosion resistance. With a team of 51–100 experienced professionals and ISO9001 certification, we deliver products that meet international standards and customer expectations.
This ERW (Electric Resistance Welded) pipe is manufactured from high-quality carbon steel, following the strict specifications of ASTM A53 Grade B. The SCH40 wall thickness provides an optimal balance between pressure-bearing capacity and weight, making it suitable for both above-ground and buried pipelines. Each pipe is cut to a standard length of 6 meters, with options for custom lengths available upon request. The pipe ends can be supplied as plain end, beveled end, or threaded, depending on your installation requirements.
Key Features & Technical Specifications
- Material: Premium carbon steel, fully compliant with ASTM A53 Grade B chemical and mechanical properties.
- Manufacturing Process: Electric Resistance Welding (ERW) ensures uniform wall thickness, smooth inner surface, and high weld integrity.
- Schedule: SCH40 – commonly used for moderate to high-pressure applications in oil and gas, water, and structural systems.
- Length: Standard 6 meters (20 ft) – reduces the number of joints and simplifies logistics.
- Surface Treatment: Available in black (as-rolled), galvanized, or coated with anti-rust oil for enhanced corrosion protection.
- Testing: Each pipe undergoes hydrostatic testing, flattening test, and bend test to ensure leak-proof performance.
- Certifications: ISO9001 quality management system; additional third-party inspections (e.g., SGS, BV) are available upon request.

Why Choose Our ERW Carbon Steel Pipe?
- Excellent Weld Quality: Our advanced ERW technology ensures a narrow, consistent weld seam that meets or exceeds API 5L requirements for oil and gas service.
- Cost-Effective: Compared to seamless pipes, ERW pipes offer similar strength at a lower cost, making them ideal for large-scale projects.
- Versatile Applications: Suitable for transporting crude oil, natural gas, petroleum products, and water under moderate pressure.
- Easy Installation: Standard 6-meter lengths reduce welding and coupling points, speeding up installation and lowering labor costs.
- Global Shipping: We ship from Qingdao Port to major markets worldwide, including North America, South America, Europe, Africa, and Asia, with reliable logistics partners.
Our quality control process covers every stage from raw material inspection to final product testing. Each pipe is marked with grade, size, heat number, and manufacturer's identity for full traceability. We also provide mill test certificates (MTC) as per ASTM A53 requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between ERW and seamless pipe for oil and gas?
A: ERW pipes are made by welding a strip of steel, offering cost savings and good dimensional accuracy. Seamless pipes have no weld seam, providing higher strength for extreme pressure, but are more expensive. For many oil and gas pipeline applications, ERW pipes are a reliable and economical choice. -
Q: Does this pipe meet API 5L standard?
A: Our ASTM A53 Grade B pipe is primarily designed to ASTM A53, but it also complies with similar mechanical properties of API 5L Grade B. If you require API 5L PSL1 or PSL2 certification, please contact us for specialized products. -
Q: What is the maximum working pressure for SCH40 pipe?
A: The working pressure depends on the pipe outer diameter, wall thickness, and material grade. For example, a 2" SCH40 pipe (3.91mm wall) has a theoretical working pressure of about 4000 psi (275 bar) under normal conditions. Always consult a qualified engineer for your specific application. -
Q: Can you provide custom lengths other than 6 meters?
A: Yes, we can supply pipes in lengths from 3m to 12m, depending on your project requirements. Custom lengths may have slightly different pricing and lead time. -
Q: What kind of surface treatment is recommended for underground pipelines?
A: For buried pipelines, we recommend FBE (Fusion Bonded Epoxy) coating or 3LPE (3-layer Polyethylene) coating for corrosion protection. We can arrange these coatings through our partner facilities. -
Q: How do you pack the pipes for export?
A: Standard export packing includes steel-bundled pipes with protective caps, or seaworthy wooden crates for small diameters. We also offer plastic wrapping and waterproof paper as needed. -
Q: Do you provide third-party inspection?
A: Yes, we can arrange inspection by SGS, BV, or other recognized agencies at the buyer's cost. Our factory also welcomes customer inspections. -
Q: What is your minimum order quantity (MOQ)?
A: Our MOQ is typically 10 tons for standard sizes and materials. For first-time customers or sample orders, we may adjust the MOQ after discussion.
