PRODUCT LEVEL
PSL 1 (Product Specification Level 1):
PSL 1 is the basic quality level for API 5L pipes, suitable for general-purpose applications. It has standard requirements for chemical composition and mechanical properties and is commonly used in low to medium pressure pipeline systems.
PSL 2 (Product Specification Level 2):
PSL 2 is a higher specification grade with stricter requirements on chemical composition, mechanical properties, and testing. It includes mandatory impact testing and full non-destructive testing (NDT), making it suitable for high-pressure, high-performance, and critical pipeline applications.
PERFORMANCE AND APPLICATION
Grade B
Yield Strength: ≥245 MPa
Applied in low-pressure natural gas pipeline systems in North America, as well as small-scale oilfield gathering projects in Central America.
X42 / X46
Yield Strength: ≥290 / 317 MPa
Used in water transmission and pumping systems in the U.S. Midwest, and municipal or regional energy distribution networks in South American cities.
X52 (Main Grade)
Yield Strength: ≥359 MPa
One of the most widely used grades, applied in shale oil and gas pipelines in Texas, onshore gathering systems in Brazil, and cross-border gas transmission projects in Panama.
X60 / X65
Yield Strength: ≥414 / 448 MPa
Suitable for high-pressure applications such as oil sands transportation in Canada and medium-to-high pressure oil and gas pipelines in the Gulf of Mexico region.
X70 / X80
Yield Strength: ≥483 / 552 MPa
Used in long-distance transmission pipelines in the United States and deepwater offshore oil and gas projects in Brazil, where high strength and reliability are required.
Technological Process
-
Raw Material Inspection – Select and inspect high-quality steel billets or coils
-
Forming – The material is rolled into a tubular or perforated shape (seamless/ERW/SAW).
-
Welding – The edges of the pipes are connected by resistance welding or submerged arc welding.
-
Heat Treatment – Increase strength and toughness through controlled heating.
-
Sizing & Straightening – Adjust the pipe diameter and ensure dimensional accuracy.
-
Non-Destructive Testing (NDT) – Inspect for internal and surface defects.
-
Hydrostatic Test – Each pipe was subjected to pressure resistance and leakage tests.
-
Surface Coating – Apply an anti-corrosion coating (black varnish, FBE, 3LPE, etc.).
-
Marking & Inspection – Label the specifications and conduct a final quality inspection.
-
Packaging & Delivery – Pack, seal, and attach a factory test certificate.

Each pipe is securely wrapped and sealed to safeguard against damage, corrosion, and environmental exposure during transport.
Fast, Global Delivery:
We provide efficient worldwide shipping to keep your project timelines on track.
Packing and Transportation
Packaging:
Packaging detail: We deliver the API tubes on IPPC fumigated wooden pallets meeting the quarantine requirements of Central America. Triple-layered waterproof membrane, with plastic end caps - every bundle is fully covered. Bundles: 2–3 tons is typical and small cranes at local construction sites can usually handle the load.
Customization Options: The normal size is 12 m for containerized shipping. Suitable for transport overland in the mountainous regions of Guatemala, Honduras, and nearby locations are the short-length versions of 8 m and 10 m.
Full Documentation Set: The shipments are accompanied by the following consignment briefing documents: Spanish certificate of origin (form B); material certificate MTC; inspection report SGS; packing list and invoice commercial. Documentation mistakes can be corrected and reissued in 24 hours.
Transportation:
We offer standard transit estimates—China → Colón, Panama (30 days); Manzanillo, Mexico (28 days); Limón, Costa Rica (35 days)—and provide contacts for trusted local carriers (e.g., TMM in Panama) to handle last-mile delivery from the port to oil fields or construction sites.
FAQ
Q1: Do your API 5L pipes meet the standards in Americas?
A: Yes They are 100% compliant with API 5L 45th Edition, ASME B36.10M and local like Mexico NOM and Panama Free Trade Zone etc. All certifications (API, NACE MR0175, ISO 9001) can be verified online.
Q2: What steel grade should I select?
Low pressure (≤3 MPa): Grade B / X42 — city gas, irrigation.
Medium pressure (3–7 MPa): X52 — land oil and gas.
High pressure (≥7 MPa) / offshore: X65 / X70 / X80 — deepwater, high strength.
Tip: Our engineers are able to advise on the most suitable grade for your project needs.
