PSL1 (Product Specification Level 1) is the standard grade. PSL2 has more stringent requirements for chemical composition, mechanical properties, and mandatory non-destructive testing. For most general pipeline applications, api 5l b psl1 is the most cost-effective choice.
We maintain a low Carbon Equivalent (CE) value, typically below 0.43%, ensuring a smooth welding process without the need for expensive pre-heating in most field conditions.
Our standard length is 6m or 12m (Random Length), but we can provide custom cuts to reduce waste at the project site.
Yes, we offer epoxy internal lining and 3LPE external coating to protect against corrosive soils and internal fluid erosion.
We provide standard 30°, 37.5°, and custom composite bevels based on the specific welding procedure (WPS) of the project.
We utilize reinforced sea-worthy packaging and specialized logistics partners to ensure the pipes arrive without surface damage or deformation.
Secure your project with API certified carbon steel solutions engineered for a century of service.
