JST cold cutting services

JST has been providing cold cutting services to both on- and off-shore clients for over 10 years.

HACCS

HACCS is Hydro-Abrasive Cold Cutting of large diameter pipe (up to 36"), plate and tanks for modification, apertures or demolition of facilities under safe conditions.

       

  • Cuts steel and reinforced concrete
  •    

  • Safe operation in hazardous offshore and onshore areas without requirement to clean or de-gas where hydrocarbons are present
  •    

  • No sparks, heat, grinding, vibration, material tension or deformation
  •    

  • Secured by tensioning chains, crawls around the pipe
  •    

  • Remote operation, allowing operator safety and extended reach control
  •    

  • Mobility — our equipment, trailer mounted, can be transported without problems to all offshore and onshore sites
