Raw Material Inspection – Choose and inspect the good quality steel billets or coils.
Forming – Roll or pierce into pipe form (Seamless / ERW / SAW).
Welding –In-pipe joints are made by electric resistance welding or submerged arc welding.
Heat Treatment – Enhance strength and toughness by precise heating.
Sizing & Straightening – Modify the diameter of the tube and confirm the size is correct.
Non-Destructive Testing (NDT) – Inspect for inward and surface flaws.
Hydrostatic Test – Test each pipe for strength and leaks.
Surface Coating – Apply corrosion protection layer (black varnish, FBE, 3LPE, etc.).
Marking & Inspection – Mark the specifications and do the final quality inspections.
Packaging & Delivery – Pack, stack, and deliver with Mill Test Certificates.
Spanish-speaking Local Service Office: Our local subsidiary provides Spanish-speaking services, offering an excellent experience and ensuring the best possible import process.
Reliable Inventory: We maintain sufficient stock to promptly fulfill your order needs.
Safe Packaging: Pipes are tightly wrapped and sealed with multiple layers of bubble wrap to prevent deformation and damage during transportation, ensuring safety.
Fast and Efficient Delivery: International delivery to meet your project delivery requirements.
Packaging Details: IPPC-fumigated wooden pallets (standard packaging in Central America), three-layer waterproof membrane (for protection from the humid environment of the tropical rain forest), plastic protective caps on both ends of the tubing (to protect against dust or any foreign matter inside). The unit load weighs 2 - 3 tons (enough for the smaller cranes common on Central American construction sites).
Customization: Standard length 12 m(for container), 8m/shorter 10m length also available(suitable for tropical land transport restriction in Guatemala ,Honduras, etc.).
One-stop service: Spanish Certificate of Origin (Form B) in your hand for free, MTC Material Certificate, SGS Report, Packing List and Commercial Invoice; and A Promise "To Reissue Wrong Documents within 24 Hours".
Shipping: Following shipment, goods will be to a neutral carrier via land and sea. For the established transit times of “China → Panama → Colon Port (30 days) , Mexico → Manzanillo Ports (28 days), Costa Rica → Limon Ports (35 days)”, we also provide short-haul transit services for “port to oil field/construction location” (local Panamanian logistics provider TMM as an example).
1. Are your API 5L steel pipes up to date standards for the Americas market?
Surely our API 5L steel pipes are in full conformance with the latest API 5L 45th Revision which is the only edition acceptable by the authorities in the Americas (the US, Canada and Latin America)? They also comply with dimensional standards of ASME B36.10M and with local standards like NOM in Mexico and the free trade zone regulations in Panama. All the certificates (API, NACE MR0175, ISO 9001) can be checked on the official websites.
2. How to Select the Proper Size of API 5L Steel Grade for My Project (for example: X52 vs X65)?
Selection your pressure, medium and environment of project : For low pressure application(≤3MPa) such as municipal gas and agriculture irrigation, Grade B or X42 is economical. For medium-pressure oil/gas transmission (3–7MPa) in onshore fields (Texas shale, for example), X52 is easily the most versatile option. For high-pressure (≥7MPa) pipelines or offshore projects (Brazil’s deepwater fields, for instance), API 5L X65/API 5L X70/API 5L X80 are also recommended for high yield strength(448–552MPa).
