Welding in a live plant means permits, fire watch and downtime. With professional LOKRING installation, you skip all three.
PT Saka Nusa Persada installs LOKRING® cold-swage fittings, a mechanical connection that replaces welding on small-bore piping. As a result, there are no sparks, no hot-work permits and no post-weld NDT.

Why Choose LOKRING Installation
- Zero hot work: a cold-swage process, so there is no fire risk.
- Fast: connections take minutes, therefore shutdown windows shrink.
- Reliable, because the seal resists vibration, corrosion and temperature swings.
- Ideal for repair, especially where welding is restricted or unsafe.
Our LOKRING Installation Services
- Fitting installation for 1/4″ to 3″ NPS in carbon steel, stainless steel, copper nickel and tubing.
- Pipe and spool replacement, including tie-ins without extended shutdowns.
- Site survey: our engineers check conditions and compatibility first.
- Genuine material supply with full batch traceability.
- Trained technicians who follow the manufacturer’s procedures.
Because each joint is visually inspected, quality control is simple and fast. In addition, the connection holds the pipe under elastic preload for its whole life, so it stays tight under vibration. As a result, LOKRING installation suits both permanent upgrades and urgent repairs where a welder cannot work safely. It also keeps permits simple, since no hot work takes place on site.
Installation Workflow
- Site survey and evaluation
