Leak Sealing

SERVICE DESCRIPTION

Leak Sealing is an online leak repair service performed on operating pipelines, without shutting down the operation, so that the system can continue to operate avoiding expensive shutdown or losses. Alstern Technologies Singapore can help you prevent expensive shutdowns by providing safe, controlled onsite and online leak repairs for any leaking process.

Leaks are often associated with the following problems :
  • Leaks are expensive
  • High pressure & temperature leaks are associated with machines that cannot shut down
  • High pressure and temperature leaks are dangerous to the safety of workers
  • High pressure and temperature leaks are threatening to properties and environment
  • Leak repairs are expensive and most methods require system to be shut down
  • Leak repairs are temporary and sometimes ineffective
  • Current methods of leak repair are not able to withstand high temperature & pressure
