Full-Scale Testing Confirms MIF Connections Exceed Code Requirements for Carbon Steel Flowlines

MPS Global recently completed a comprehensive destructive testing program on 16-inch mechanical interference fit (MIF) connections, demonstrating that this weld-free technology significantly surpasses industry design standards for carbon steel flowlines. The testing program evaluated four full-scale joints fabricated from API 5L carbon steel against ASME B31.4/B31.8 criteria through bending tests, internal pressure tests, cyclic pressure-fatigue […]
Understanding API STD 5MIF:2025 – A New Era for Mechanical Interference Fit Connections

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 […]
