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

   

• Cuts tanks and vessels

Features

JST HACCS uses the latest water abrasive cold cutting techniques with direct injection of garnet into the water stream.

   
• Operating at 4,000 psi (280 bar)

   

• Remote operation up to 50 metres (no hand held cutting)

   

• Cutting head is controlled at the desired speed and angle

   

• Cutting action is shock free, leaves no heat-affected zones and is completely inert

   

• Integrated package with water and diesel fuel supply

   

• Linear manipulator — ideal for plate, tank bottoms or entry cuts

   

• Cylindrical manipulator — for any cylindrical objects up to 48 diameter including pipe, flare lines, down line pipe & vessels

Key benefits

   
• Safe, non-toxic and silica-free — no risk of silicosis
