API-certified machine shop operations specializing in geothermal safety valve repair, recertification, and custom manufacturing in Indonesia.
Geothermal steam environments subject wellhead valves and blowout preventers (BOPs) to harsh scale, hydrogen sulfide (H2S), and severe thermal cycling.
PT TNG operates a specialized facility equipped to remanufacture, re-seat, overlay, and pressure-test severe-service valves to original API standards.
Strategically located in Bekasi, West Java to serve geothermal operators across Java, Sumatra, and North Sulawesi.
Indonesia holds one of the world's largest geothermal resources, and operators across Java, Sumatra, and North Sulawesi rely on wellhead safety valves and blowout preventers that must survive hydrogen sulfide (H2S), silica scale, and aggressive thermal cycling. Replacing this equipment is costly and slow; refurbishing it to original API standards is faster, cheaper, and keeps rigs running.
PT TNG's Cikarang machine shop remanufactures severe-service valves from the ground up — full disassembly, chemical cleaning, non-destructive testing (NDT), hardfacing with Inconel and Stellite corrosion-resistant cladding, precision CNC machining and lapping to micro-inch tolerances, and high-pressure hydrostatic and gas shell/seat testing up to 15,000 PSI. Every job carries full certification traceability for regulatory compliance.
Operating to API 6A, API 16A, and ISO 9001 standards, our facility gives Indonesian and regional geothermal operators a local, responsive alternative to overseas repair — cutting lead times and replacement costs while extending the service life of critical wellhead equipment.
