PSL 1 (Product Specification Level 1) : For pipelines built to a basic standard quality level.
PSL 2 (Product Specification Level 2) : Using higher mechanical properties, tighter chemical controls and NDT, more aggressive specification.
| Item | PSL1 | PSL2 | Notes |
| Chemical Composition Control | Standard limits on C, Mn, P, S | Stricter limits, lower P and S; additional microalloy element control allowed | PSL2 is more suitable for low-temperature and corrosive environments |
| Yield Strength (MPa) | According to grade specification | Same as PSL1; slightly higher for some high-grade steels | Basic mechanical requirements are similar |
| Tensile Strength (MPa) | According to grade specification | Same as PSL1 | |
| Elongation (%) | According to grade specification | Same as PSL1 | |
| Low-Temperature Impact (Charpy V-Notch) | Optional or per end-use requirement | Mandatory; typically tested at -20°C or -50°C | Enhances toughness at low temperature |
| Weldability | Meets standard requirements | Stricter, weldability tests often required | PSL2 demands higher weld performance |
| Dimensional Tolerance | Standard range | Stricter | PSL2 has tighter control on diameter and wall thickness |
| Defect Control / NDT | Standard inspection; UT/RT optional | Mandatory UT/RT/MPI | Ensures higher pipeline safety |
| Application Environment | General pipeline transportation | High-pressure, low-temperature, corrosive pipelines | PSL2 is preferred for projects with high safety requirements |
| Cost | Relatively lower | Slightly higher | Due to stricter inspection and manufacturing requirements |
| API 5L Grade | Key Mechanical Properties (Yield Strength) | Applicable Scenarios in the Americas |
| Grade B | ≥245 MPa | North American low pressure natural gas pipelines; Small oil field gathering pipelines in Central America |
| X42/X46 | >290/317 MPa | US Midwestern agricultural irrigation pipelines; South American urban energy grids |
| X52 (Main) | >359 MPa | Texas shale oil pipelines; Brazil onshore oil and gas gathering pipelines; Panama trans-boundary natural gas pipelines |

| X70/X80 | >483/552 MPa | US long-haul oil pipelines; Brazil deepwater oil and gas platforms |
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 Guarantee
Our API 5L steel pipes are palletized (wooden pallets fumigated with IPPC which is the standard for Central America and meets all the phytosanitary requirements for export), then wrapped in six layers of plastic. Your pipe is individually packaged with three layers of waterproof membranes which due to the high humidity in the tropical rain forest are designed in such a way that moisture cannot get in. A high-strength plastic protective flag and plug are installed on the two ends of the pipe to prevent dust, impurities and foreign matter entering on transportation and storage in site, so as to keep the product clean and intact. Each pipe section weighs 2-3 tons, an ideal size and weight for the small cranes typically found on Central American job sites, this enables safer handling and more efficient construction.
Tailored Specifications
ISO dimensions: standard length is 12 meters, suitable for container loading and international logistics transportation.
Short Length Options: 8’ and 10’ for projects located in the tropics in Guatemala and Honduras where overland transportation is constrained.
Several options - we adapt to your needs! The multiple specifications can flexibly satisfy the demands of the project and guarantee the convenience of transportation and construction efficiency.
One-Stop Document Service
In an effort to facilitate successful customs clearance and project construction for our clients in the Central American market, we offer total export and material documentation certification at no cost, such as:
Certificate of Origin (Form B)
MTC Material Testing Certificate
SGS Test Report
Packing List
Commercial Invoice
In addition, we guarantee that any erroneous or misplaced document will be reissued within 24 hours, ensuring the project will not suffer further delays.
Professional Transport Arrangements
Once the shipment has been dispatched, the merchandise will be delivered to a neutral carrier by land and sea transportation combination mode, the transportation will be safe and reliable. The following are the primary routes of transportation and ETA:
China → Colon, Panama: ~30 days
China → Manzanillo, Mexico: Around 28 Days
China → Limon, Costa Rica: ~35days
In case of project requirements, we offer short-haul transportation services from ports to oil fields or job sites. For instance, with local logistics partner in Panama TMM, we provide end-to-end logistic solutions, delivering project material in a timely and safe manner.
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). Our engineering team will offer you a free grade recommendation according to your project details.
