Product Level

PSL 1 (Product Specification Level 1): A basic standard quality level intended for pipelines.
PSL 2 (Product Specification Level 2): Higher mechanical properties, stricter chemical control and NDT, more severe specification.

Performance and Applications

API 5L Grade	Key Mechanical Properties (Yield Strength)	Applicable Scenarios in the Americas
Grade B	≥245 MPa	Low-pressure gas pipelines in North America, small oilfield gathering 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	Shale oil pipelines in Texas, onshore oil & gas gathering in Brazil, 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.

api 5l Sizing & Straightening royal group_

Sizing & Straightening – Adjust pipe diameter and ensure dimensional accuracy.

api 5l Non-Destructive Testing royal group_

Non-Destructive Testing (NDT) – Check for internal and surface defects.

api 5l Hydrostatic Test Testing royal group_

Hydrostatic Test – Test each pipe for pressure resistance and leaks.

Royal Steel Group Advantage（Why Royal Group Stands Out for Americas Clients?）

Local Branch and Spanish Support:Our local branches provide help in Spanish; take care of your customs clearance and guarantee the best way of importation.

Dependable Stock Availability:We have sufficient stock to fulfill your order promptly.

Safe packaging: Pipes are wrapped tightly in multiple layers of bubble packs and are sealed airtight to prevent deformation and damage, which maintains the integrity of the product during transportation.

Fast & Efficient Delivery:To anywhere in the world to meet your project deadlines.

Packing And Delivery

Packaging Details: Wood pallets IPPC fumigated (Standard dunnage for Central America), 3-layer waterproof membrane (to protect against moisture of the rain forest), plastic protective caps on both ends of pipe (makes it difficult for dust or debris to get in), single bundle weight 2 – 3 tons (central American construction sites have small cranes, that's why this weight is good for them).

Customization: Standard 12m (container suitable), 8m/10m small length versions available (suitable for transport restrictions of tropical land route in Guatemala, Honduras, etc.).

All-In: Provision at no additional cost of Spanish language version of Certificate of Origin (Form B), MTC material certificate, SGS test report, packing list and commercial invoice; the assurance to “ reissue wrong documentation within 24 hours”.

Transport: Once goods are shipped, they are delivered by land and sea to neutral carriers. For standing transit times "China → Colon Port, Panama (30 days), Manzanillo Port, Mexico (28 days), Limon Port, Costa Rica (35 days)," we also share short-distance delivery partners (e.g., TMM, a local logistic company in Panama) for "port to oil field/construction site".

FAQ

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), X65/X70/X80 are also recommended for high yield strength(448–552MPa).
