Select steel plates conforming to CC65 grade and test their chemical and mechanical properties.
Cut, trim, and roll the steel plates into cylindrical shapes.
Weld straight seams using EFW/HFW technology and monitor weld quality in real time.
Normalize or anneal as needed to improve toughness and uniformity.
Straighten the pipes and ensure accurate outer diameter and wall thickness.
Perform nondestructive testing on the welds using UT/RT or other methods.
Verify the safety of the pipeline under operating pressure through hydraulic testing.
Apply rust prevention treatment and install end caps for protection.(black varnish, FBE, 3LPE, etc.).
Perform final inspection of dimensional performance and provide standard MTC and test reports.
Use rust- and corrosion-resistant packaging and provide comprehensive transportation services.
Local Spanish Support
Our Madrid office has a professional Spanish-speaking service team, creating a smooth and seamless import process for our Central and South American clients, delivering a high-quality customer experience.
Ample Inventory Guarantee
A large stock of steel pipes ensures rapid response to your order needs, providing solid support for on-time project progress.
Safe Packaging Protection
Each steel pipe is individually sealed with multiple layers of bubble wrap, and then further protected with an outer plastic bag. This double protection ensures that the product will not be deformed or damaged during transportation, safeguarding its integrity.
Fast and Efficient Delivery
We offer international delivery services tailored to your project schedule, relying on a robust logistics system to ensure timely and reliable delivery.
Robust Packaging Meeting Standards
The steel pipes are packaged on IPPC fumigated wooden pallets, fully complying with Central American export regulations. Each package is equipped with a three-layer waterproof membrane to effectively protect against the local tropical and humid climate; plastic end caps ensure a tight seal against dust and foreign objects entering the pipe. Single-piece loading is controlled at 2-3 tons, precisely meeting the operational needs of small cranes commonly used on construction sites in the region.
Flexible Customizable Length Specifications
The standard length is 12 meters, perfectly suited for container shipping. For land transport restrictions in tropical countries such as Guatemala and Honduras, additional 10-meter and 8-meter lengths are available to solve transportation compatibility issues.
Complete Documentation and Efficient Service
We provide a one-stop service for all necessary import documents, including the Spanish Certificate of Origin (Form B), MTC Material Certificate, SGS report, packing list, and commercial invoice. If any documents are incorrect, they will be corrected and resent within 24 hours to ensure smooth customs clearance in Ajana.
Reliable Transportation and Logistics Guarantee
After production is completed, goods will be handed over to a neutral freight forwarder and delivered via a combined land and sea transport model. Transit times at key ports are as follows:
China → Panama (Cologne): 30 days
China → Mexico (Manzanillo): 28 days
China → Costa Rica (Limon): 35 days
We also provide short-distance delivery services from ports to oil fields and construction sites, efficiently completing the last-mile transportation connection.
1. Are your ASTM A671 CC65 CL 12 EFW steel pipes compliant with the latest standards for the Americas market?
Surely, our ASTM A671 CC65 CL 12 EFW carbon steel pipes are fully compliant with the latest ASTM A671 specification, which is widely accepted across the Americas—including the United States, Canada, and Latin America—for low- to medium-pressure applications in oil, gas, water, and structural service. They also meet dimensional standards such as ASME B36.10M, and can be supplied in conformity with local regulations including NOM standards in Mexico and Panama Free Trade Zone requirements. All certifications—ISO 9001, EN 10204 3.1/3.2 MTC, Hydrostatic Test Report, NDT Report—are verifiable and traceable.
2. How to Select the Proper Class/Grade of ASTM A671 Pipe for My Project (for example: CC60 vs CC65 vs CC70)?
Select your pipe class according to your pressure, temperature, and service conditions:
For general low-pressure water or structural applications (≤3MPa), CC60 or CC65 Class 12 offers excellent cost-effectiveness.
For medium-pressure pipelines (3–5MPa) carrying steam, oil, or gas in refinery or power plant environments, CC65 CL 12 is the most commonly used and versatile option.
For higher-pressure or higher-temperature service, CC70 (CL 22 or CL 32) is recommended due to its higher yield strength and enhanced weld integrity.
Our engineering team can provide a free technical selection guide based on your project’s design pressure, medium, temperature, and welding requirements.
