In high-risk industries like oil & gas, petrochemicals, and power generation, safety is never negotiable. The smallest failure—especially in critical bolting—can lead to major operational downtime, costly repairs, environmental harm, or even danger to human life. This is why adherence to the API 20E standard is not just a requirement—it’s a responsibility.
At NP Energy, we don’t just meet the API 20E standard—we embed it into every layer of our bolting distribution process. From sourcing and testing to traceability and documentation, our commitment to safety, quality, and reliability is evident in everything we deliver.
The American Petroleum Institute (API) developed the API 20E standard to define stringent requirements for carbon and alloy steel bolting used in critical oil & gas equipment. It applies to flanged joints, pressure-containing systems, subsea components, and any application where failure is not an option.
API 20E governs:
Bolts manufactured and distributed under API 20E are classified into three Bolting Specification Levels—BSL-1, BSL-2, and BSL-3—each representing increasing levels of scrutiny based on the criticality of the application.
At NP Energy, API 20E is more than a box to check—it’s the foundation of how we operate. We understand that our clients rely on us for fasteners that perform flawlessly in the most demanding environments. That’s why we’ve built our entire distribution model around the principles of compliance, consistency, and confidence.
Here’s how NP Energy ensures API 20E compliance every step of the way:
We work exclusively with API 20E/20F-compliant manufacturers who meet or exceed all technical and procedural requirements, including:
This guarantees that every bolt, stud, or nut supplied by NP Energy has a clear, verifiable chain of quality from raw material to finished product.
Traceability is a core requirement of API 20E—and a top priority for NP Energy. Each fastener we deliver includes:
Whether for a standard project or a high-pressure sour gas installation, our traceability systems ensure our customers know exactly what they’re getting—and where it came from.
Our quality assurance process goes far beyond visual checks. Every fastener we supply undergoes a multi-level inspection process to ensure total compliance with API 20E and related standards.
We coordinate and review:
Each order is backed by a Certificate of Conformance (CoC) and inspection data, providing our customers with clear proof of compliance.
NP Energy supplies fasteners across all three BSL levels, depending on the criticality of the application:
From B7 and L7 bolts to 718 Inconel and B8M stainless studs, we provide a wide range of materials and coatings—with API 20E/20F-compliant documentation to match.
We understand the pressure of meeting project timelines. NP Energy maintains a robust inventory of API 20E-compliant bolts, studs, and nuts, ready to ship quickly and backed by all required testing and traceability documents.
For urgent jobs, shutdowns, or specialized orders, we offer:
We see ourselves as a trusted partner, not just a vendor. Our experienced team supports every customer with:
Your goals are our goals—whether it’s passing a site audit, completing an offshore project, or sourcing compliant fasteners under tight deadlines.
NP Energy’s API 20E-compliant bolting supports critical projects across a wide range of sectors:
Wherever failure isn’t an option, NP Energy delivers fasteners that meet the highest industry standards
