At MPS, we recognize the importance of standardization in maintaining safety, reliability, and performance in the oil and gas sector. In January 2025, the American Petroleum Institute (API)—the recognized authority in global oil and gas standards— released the API STD 5MIF: 2025, the first official standard dedicated to Mechanical Interference Fit (MIF) connections. The standard offers foundational guidance on the design and application of MIF technology, especially for the assembly of API 5L pipe.
MIF connections form robust mechanical joints through precision-fit components—eliminating the need for welding while ensuring pipeline integrity. By defining the key elements of MIF and aligning expectations across engineers, manufacturers, and suppliers, API 5MIF sets the stage for greater consistency and innovation in pipeline construction.
API has a long-standing reputation for creating standards that uphold the quality and safety of critical process equipment, and this standard continues that legacy. API 5MIF is intended as a technical reference for project engineers, end-users, connection manufacturers, and suppliers involved in pipeline design. As the industry continues to evolve, this standard provides a common framework for adopting MIF technology, paving the way for broader acceptance and safer, more efficient pipeline assembly practices worldwide.
MPS Global has been a trusted provider of MIF solutions for over 50 years. Our Connexus technology delivers strong, safe, and cost-effective connections—accelerating construction speed by more than 10X compared to traditional welding methods.
We remain committed to advancing pipeline safety, reliability, and performance through standardized, cutting-edge solutions.
