As a trusted manufacturer based in Liaocheng, Shandong, China, Hemaokang Steel (Shandong) Co., Ltd. is proud to offer the ASTM A53 Grade A Sch40 Galvanized Steel Pipe 1.5 Inch Nominal 2.0mm Wall Thickness ERW. This product combines the strength of ERW manufacturing with the corrosion resistance of hot-dip galvanizing, making it a reliable choice for various industrial applications. With our ISO9001 certification and annual export value exceeding US$50 million, we ensure consistent quality and timely delivery to global markets.
Our galvanized steel pipe is specifically designed to meet the rigorous demands of fluid transportation, structural support, and underground piping systems. The 1.5-inch nominal size and Schedule 40 wall thickness (2.0mm) provide a balance of strength and flexibility, while the ERW process ensures uniform wall thickness and smooth finish. Below we detail the key features, technical specifications, and benefits of this product.
Key Features & Technical Specifications
- Standard Compliance: Manufactured in accordance with ASTM A53 Grade A, ensuring consistent mechanical properties and dimensional accuracy.
- Galvanized Coating: Hot-dip galvanized inside and out, providing excellent protection against rust and corrosion, extending service life in harsh environments.
- ERW Manufacturing: Electric Resistance Welding process creates a strong, uniform weld seam without filler metal, resulting in high strength and pressure containment.
- Nominal Size & Wall Thickness: 1.5 inch nominal (outside diameter 1.9 inch / 48.3 mm) with 2.0 mm wall thickness (Schedule 40), suitable for medium-pressure applications.
- Versatile Application: Ideal for water supply, gas lines, oil pipelines, structural scaffolding, fence posts, and electrical conduit.
- Customizable Lengths: Available in standard random lengths (20 ft / 6 m) or custom lengths upon request.
- End Finish: Plain ends, beveled ends, or threaded ends as per customer requirement.

Frequently Asked Questions (FAQ)
-
What is the difference between ASTM A53 Grade A and Grade B?
Grade A has lower tensile and yield strength (min 330 MPa tensile, 205 MPa yield) compared to Grade B (min 415 MPa tensile, 240 MPa yield). Grade A is suitable for lower-pressure applications where ductility is preferred, while Grade B is for higher strength requirements. -
Can this pipe be used for underground water lines?
Yes, the hot-dip galvanized coating provides excellent corrosion resistance for underground installations. However, for aggressive soil conditions, additional wrapping or cathodic protection may be recommended. -
What lengths are available?
Standard lengths are 20 ft (6.0 m) or random lengths between 16–22 ft. Custom lengths are available upon request with a minimum order quantity. -
Is the pipe threaded or plain end?
We offer plain ends, beveled ends, or threaded ends with couplings. Please specify your requirement when ordering. Threaded ends are available for NPT standards. -
How is the galvanized coating applied?
Our pipe is hot-dip galvanized after manufacturing. The pipe is cleaned, fluxed, and dipped in molten zinc, resulting in a metallurgical bond that provides long-lasting protection. -
Do you provide test certificates?
Yes, we supply mill test certificates (MTC) that comply with EN 10204 Type 3.1, including chemical composition, mechanical properties, and hydrostatic test results. -
What is the minimum order quantity (MOQ)?
For standard sizes, MOQ is typically 1 ton (approximately 20 pieces). For custom lengths or special finishes, MOQ may be higher. Contact our sales team for details. -
Can I get a sample before placing a bulk order?
Yes, sample requests are welcome. We can provide a 1-meter sample with freight collect. Please contact us to arrange.
