Advantages

• It prevents the line stop or interruption of service
• Without emissions or product loss
• It avoids redesigning the pipe line sections and it reduces planning costs

Method of Implementing

• Prior to Hot Tap, welding of Fitting, that includes a full-bore valve.
• Installing the Hot Tap machine.
• Carrying out the Pressure Test.
• Opening the Hot Tap valve.
• Forward speed of the drill and performing the perforation.
• Recovering the cut off coupon (disc).
• Closing the valve.
• Depressurising the casing.
• Removing the machine.
• The new line is already operational through the valve.

Advantages

• The system remains running reducing downtime
• Highly stable method due to its mechanical functioning
• State-of-art equipment

Method of Implementing

• Installing fitting Line Stop.
• Installing recoverable valve.
• Installing Hot-Tap machine.
• A Hot-Tap is carried out through the valve.
• Connection of the line stop machine to the valve.
• Carrying out Line Stop (line sealing).
• After repair / replacement, the Line Stop is removed.
• Installation of the completion disc.
• Installing blind flange.

Advantages

• Sealing can be carried out under pressure and very high temperature conditions
• The operation is a safe and reliable way of sealing pipes

Method of Implementing

• Welding of HI-stop fitting and pressure test.
• Line perforation, passing through it completely in a sole operation.
• Installing a through shut-off element.
• Once the operation is ended, a completion disc and a blind flange are placed, and the new line is in service again.

Advantages

• Non-invasive, quick, simple and economic method
• No permanent change is needed in the piping
• Lines can be disconnected with no need of putting the line out of service
• The piping does not need mechanical preparation nor welding
• Applying the cryogenic plug does not permanently alter the piping’s mechanical properties.

Applications

• Enclosure Method -> Pipes of all diameters
• Method of Pads -> Pipes Up to 4″

Advantages

• Reduction in weight and cost in equipment compared to other techniques
• Large range of sizes
• It adapts well to irregular surfaces inside the piping.

Applications

Industry:
• Solar Thermal Power Plants with HTF
• Steam and Water Generation Power Plants
• Valid for other types of fluids, once the manufacturing material has been analysed

Construction:
• Refrigerating circuits and air-conditioners at Hospitals, Shopping Centres, Hotels, Sport Centres, etc.
• Leak containment in manholes
