PRODUCT LEVEL
PSL 1: It is equivalent to the pipeline quality for normal use.
PSL 2: It is a superior quality pipe with higher mechanical properties and tighter chemical controls, It also allows NDT testing.
PERFORMANCE AND APPLICATION

| Grade B | ≥245 MPa | North American low-pressure gas pipelines and small-scale oilfield gathering networks in Central America. |
| X42/X46 | >290/317 MPa | Agricultural irrigation in the U.S. Midwest, municipal energy networks in South America |
| X52 (Main) | >359 MPa | Texas shale oil pipelines, onshore oil and gas gathering in Brazil, and cross-border gas transmission in Panama. |
| X60/X65 | >414/448 MPa | Oil sands transportation in Canada, medium-to-high pressure pipelines in the Gulf of Mexico |
| X70/X80 | >483/552 MPa | Long-distance oil pipelines in the U.S., deepwater oil & gas platforms in Brazil |
Technological Process
-
Raw Material Inspection – Select and inspect high-quality steel billets or coils.
-
Forming – Roll or pierce the material into pipe shape (Seamless / ERW / SAW).
-
Welding – Join pipe edges by electric resistance or submerged arc welding.
-
Heat Treatment – Improve strength and toughness through controlled heating.
-
Sizing & Straightening – Adjust pipe diameter and ensure dimensional accuracy.
-
Non-Destructive Testing (NDT) – Check for internal and surface defects.
-
Hydrostatic Test – Test each pipe for pressure resistance and leaks.
-
Surface Coating – Apply anti-corrosion coating (Black varnish, FBE, 3LPE, etc.).
-
Marking & Inspection – Mark specifications and perform final quality checks.
-
Packaging & Delivery – Bundle, cap, and ship with Mill Test Certificates.
Our Advantages
Local Branch & Support in Spanish: Our local offices offer assistance in Spanish, take care of customs clearance and supervise the import process to its finalization.
Dependable Stock Situation: We hold so much stock that your orders will be dispatched to you in no time.
Safe Packaging: We take special care to wrap the Pipes with multiple layers of bubble wrap and it is sealed airtight to keep the Pipes from deforming or getting damaged, on top of that the Pipes are placed inside a strong cardboard box to make sure the product survives the trip.
Quick and professional dispatching and delivery: We ship worldwide to enable you to meet your project deadline.
Packing and Transportation
Packaging:
Packaging Pipes are packed on IPPC fumigated wooden pallets (compliant with Central American quarantine) from API 5L pipe factory, a 3 layers waterproof membrane for protection against moisture from rain forest and plastic caps to avoid any enter of dirt.
Single bundle weight：2-3tons, can be handled by small cranes on construction site in central America.
Available options Standard 12m lengths (container-friendly) and 8m and 10m short versions for inland transport over the mountains in countries such as Guatemala and Honduras.
Our Offer Spanish versions of the CoO (FORM B), MTC material certificate, SGS test report, packing list and commercial invoice. Errors in documentation are amended and reissued within 24hours.
Transportation:
For transit times of “China → Colon Port, Panama (30 days), Manzanillo Port, Mexico (28 days), Limon Port, Costa Rica (35 days),” we provide information on short-distance delivery partners (such as TMM, a local logistics company in Panama) for “port to oil field/construction site”.
FAQ
1. Do your API 5L pipes meet Americas standards?
Yes. Fully compliant with API 5L 45th Revision, ASME B36.10M, and local regulations (e.g., Mexico NOM, Panama FTZ). Certifications like API, NACE MR0175, ISO 9001 are verifiable online.
2. How to choose the right steel grade?
-
Low-pressure (≤3 MPa): Grade B or X42, cost-effective for municipal gas/irrigation.
-
Medium-pressure (3–7 MPa): X52, ideal for onshore oil/gas (e.g., Texas shale).
-
High-pressure (≥7 MPa) / Offshore: X65–X80, for deepwater or high-stress pipelines.
