Inspection of Raw Materials –select and check the quality of steel billets or coils.
Forming – Roll or punch into a tubular shape (Seamless / ERW / SAW).
Welding – Electric resistance welding (ERW) or submerged arc welding (SAW) is used to form in-pipe joints.
Heat Treatment – Build strength and toughness through heating with precision.
Sizing & Straightening – Change the diameter of the tube and check the size is right.
Non-Destructive Testing (NDT) - Check for internal and surface defects.
Hydrostatic Test - Test each pipe for strength and leak tightness.
Surface Coating – Apply corrosion protection layer (Black Varnish, FBE, 3LPE, etc.).
Marking & Inspection – Mark the specifications and make the final inspection.
Packaging & Delivery - with mill test certificate pack,stack,delivery.

Each package has a three-layer waterproof membrane to resist the humid tropical climate, while the plastic end caps prevent dust and foreign matter reach inside the tubes. Unit loads are 2 to 3 tons that fit smaller cranes like those are widely utilized on construction jobsites in the area.
Custom Length Options: The standard length is 12 meters, which can be easily transported by container. You can also find the shorter lengths of 10 meters or 8 meters due to tropical land transport limitations in countries such as Guatemala and Honduras.
Complete documentation & Service: We will provide all the documentation required for easy import such as Spanish Certificate of Origin (form B), MTC Material Certificate, SGS Report, Packing List and Commercial Invoice. Wrong documentation will be corrected and re-sent within 24 hours to ensureajana smooth custom clearance.
Dependable Shipping & Logistics: Upon production, good are handed to a neutral shipper who carries them by land and sea. Usual transit times are:
China → Panama (Colon Port): 30 days
China →Mexico( Manzanillo Port): 28 days
China → Costa RicaCosta Rica (Limon Port): 35 days
We also offer short-haul delivery from port to oil field or construction site, working with local logistics partners such as TMM in Panama to best handle last-mile transport.
1. Are your API 5L steel pipes suitable for the Americas market?
Absolutely. Our API 5L steel pipes conform to the latest API 5L 45th edition standard, the only officially recognized version in the Americas (USA, Canada, and Latin America). They also meet ASME B36.10M dimensional requirements, as well as local standards such as Mexico's NOM standard and the Panama Free Trade Zone standard. All certifications (API, NACE MR0175, ISO 9001) can be found on our official website.
2. How do I choose the appropriate API 5L steel pipe grade (e.g., X 52 or X 65) for my project?
Pressure, medium, and project environment selection: For atmospheric environments, grade selection is as follows: For low-pressure (≤3 MPa) applications such as city gas and agricultural irrigation, grade B or X 42 is the most economical choice. In onshore applications, X 52 is undoubtedly the most versatile choice for transporting medium-pressure oil and gas (3-7 MPa). Our engineering team will provide you with free grade recommendations based on your project details.
