Metal Kingdom, a leading provider of valve and pipeline testing and repair equipment since 1994, today announced the successful deployment of its MJ-400 Portable Valve Grinding System at a major onshore oilfield operated by a national energy company in the Middle East.

Facing recurring leaks in critical gate valves, the operator was constrained by traditional methods that required removing valves for off-site repair—a process causing up to 5 days of production downtime per incident. The need for a faster, on-site solution was urgent.

Metal Kingdom’s technical team proposed and executed a field trial using the MJ-400 system. Within the first deployment, field maintenance crews were able to:

Complete valve reseating on-site in under 2 hours, compared to the previous 5-day cycle.

Achieve a perfect seal pressure test post-repair, eliminating repeat leakage issues.

Avoid an estimated $250,000 in potential lost production for a single valve event.

This case underscores Metal Kingdom’s commitment to moving beyond equipment sales to delivering actionable field solutions. The MJ-400 system is part of a comprehensive product line designed to empower maintenance teams in the oil & gas, power generation, and maritime industries to tackle valve and pipeline integrity issues swiftly and safely.
