Following the successful launch of the Rapid Window Cutter for Ductile Iron, SVI has worked with Wales & West Utilities again to develop a cutter which allows the removal of a window from a steel main.

Previously, like all GDNs, WWU had not been able to plan the replacement of its 200km steel networks other than by inefficient ‘open cut’ methods.

The design of this tool builds on the successful engineering of the Rapid Window Cutter for Ductile Iron with modifications to the air powered motor and blade system.

The cutter makes both semi-circumferential and longitudinal cuts, the latter using a light weight, easy to fit guide frame that allows free linear movement.

The Rapid Window Cutter for Steel is suitable for tier 1 mains with a maximum cutting depth of 13mm and comes with depth control discs which allow it to cut inserted mains safely without damaging the PE. The motor is air driven and is powered from a typical site compressor. The machine is quick to set up and easily operated by one person.

Typical cutting speed – a typical ‘top tee’ size window in less than 30 minutes; this is dramatically faster compared with existing approved tooling.

Benefits

  • Ideal for cutting windows in dead or live inserted mains without damaging PE
    Suitable for all sizes of steel mains up to 13mm depth
  • Extremely quick cutting time compared with existing equipment
  • Depth control discs prevents damage to inserted PE
  • Quick assembly time
  • One person operation – simple to use & lightweight
  • Keep trench size to a minimum – no need to excavate under the main
  • Safe to use – cutting blade mounted safely away from the operator’s hand
  • Water feed line to prevent sparking and prolong blade life
  • Powered from standard site compressor – no extra power source needed

Ductile iron mains are notoriously problematical because they cannot be broken out like cast iron; now there is a solution with The Rapid Window Cutter.

The machine was developed in collaboration with Wales & West Utilities, who identified the need for a faster window cutting technique to allow them to extend their use of Live Mains Insertion onto their ductile network.

The new design introduces a revolutionary alternative to established methods, typically cutting a window on a 100mm/4” ductile iron main in under 12 minutes. Customers report that this is 50% faster than traditional equipment.

The hand-held tool is designed for precise, fast cutting of windows in abandoned or inserted ductile mains, without damaging the previously inserted PE. Easy to operate, the cutter connects to an onsite compressor. The operative simply engages the trigger, lowers the blade and glides the unit along or around the main. The chassis pivots easily to change from circumferential to longitudinal cuts.

The Rapid Window Cutter won first place in the Best Gas Improvement Category at The UK Energy Innovation Awards 2015.

Benefits:

  • Fast: A typical size window is cut in less than 15 minutes – 50% faster than traditional equipment
  • Safe: The cutting disc is mounted well away from the operator’s hand; automatic emergency cut-off on trigger handle
  • Cost effective: Available to hire, purchase or carried out as a Contract service
  • Easy to use: Compact, lightweight and simple to operate – one man operation
  • Precise: Depth control discs prevent damage to inserted PE; Ideal for use in Live Mains Insertion and dead insertion projects
  • Clean: No water is needed resulting in a cleaner trench
  • Adaptable: Designed to be compact, no need to dig under main
  • Air powered: Uses on-site compressor, avoiding need for extra power source

The Rapid Rotary Cutter

The Rapid Rotary Cutter offers a solution to the problems associated with making circumferential cuts on ductile iron pipes.

The Rapid Rotary Cutter is an air powered tool designed to cut around a ductile iron main. It is extremely fast, cutting a 4″ main in approximately 2 minutes. Incorporating depth gauges, the cutter is safe to use on inserted host pipes and allows immediate access.

The Rapid Rotary Cutter comprises two aluminium shells, with an air motor on the top shell, that interlink around the perimeter of the main. Using minimum effort the operator rotates the unit 360° by hand, to give a very precise circumferential cut.

Benefits:

  • Fast: Extremely quick cutting time – approximately 2 minutes to cut a 4” ductile iron main
  • Versatile: Ideal for use in Live Mains Insertion and dead insertion projects
  • Quick assembly: The two shells are connected over the main in seconds
  • Adaptable: One unit for all three sizes using different frames; 75mm/100mm, 150mm and 200mm (3”/4”, 6” and 8”)
  • Easy to use: Compact, lightweight and simple to use – one man operation
  • Convenient: Needs smaller trench than traditional cutters – less than 10cm clearance needed around the main
  • Safe: The cutting blade is mounted away from operator’s hand
  • Precise: Depth control discs prevent damage to inserted PE
  • Clean: No need for water when cutting ductile resulting in cleaner trench

In the Gas industry, Keel Cutters are an essential tool when carrying out alterations and diversions – any instance where a circumferential cut is required on a main whether or not it has already been inserted with PE.

When fitted on the main, minimum clearance is required to allow the blade to track around the pipe delivering a clean circumferential cut in minutes. The Keel Cutters can cut steel, cast iron, ductile iron, plastic, cement and other types of pipe up to 1500mm diameter.

The Keel Cutter can also be used in preparation when welding by using a specialised bevelled angle blade.

Available for hire or purchase. Pipe cutting is also offered as a contract service.

Benefits:

  • Cutter automatically tracks around the pipe
  • Cuts steel, cast iron, ductile iron, asbestos*, cement and plastic pipe
  • Fast cutting time – typicaly 8 minutes to cut a 300mm diameter cast iron pipe

NEW – CRACKERJACK™

CRACKERJACK™

CRACKERJACK™

Breaking out redundant or inserted cast iron mains has always been risky as operators use a variety of hand-held tools, which are labour intensive and associated with hazards to the workforce and even to passers-by.

The alternatives – though effective and well designed – have been expensive; but Steve Vick believe that they have the answer to this longstanding problem with the CRACKERJACK™, a manually operated mains cracker that combines performance and easy handling with low cost.

The major difference between the  CRACKERJACK™ and other mechanised crackers on the market is its’ power source. Instead of being battery operated, the Crackerjack™ is operated from a standard site compressor via an air over hydraulic pump which delivers 700 bar of hydraulic pressure, plenty of power to crack cast and spun iron mains up to 6” in diameter in a couple of minutes.

The operator uses a foot pedal on the pump to open and close the jaw of the CRACKERJACK™ and is thus able to control the pressure applied so that just sufficient force is used to crack the metal.

By rotating and moving the CRACKERJACK™ along the main, the pipe can be broken out in several places to facilitate the removal of the redundant section or to gain access to an inserted PE pipe, making it the ideal system for live mains insertion.

Benefits:

  • Fits all diameters from 3” to 6” with a simple adjustment
  • 20 tonnes of break-out force cracks a 6” main in minutes
  • Low cost compared with existing mechanical tools
  • Safe for use on inserted mains – controlled break out avoids damaging internal PE
  • Lightweight (15kg) and easy to handle
  • Set up takes moments – no need to enter the trench
  • Avoids the safety risks of using podger bars or sledge hammers
  • Minimum excavation required – needs only 75mm either side of the main
  • Ideal for Live Mains Insertion

MACAW Pipe Crackers

Breaking out cast iron mains has been a long standing health and safety concern in the gas industry. This is due to the labour intensive tooling available, such as a sledge hammer or ‘podger’ bar, both of which have been associated with causing injury to operatives.

Steve Vick International offers the solution with the ‘MACAW’ Pipe Cracker range, so called because its pipe cracking arms resemble the powerful beak of the South American bird!

The MACAW attaches to the quick-hitch or bucket pins of a mini excavator. Controlled from the cab, and using the excavator’s hydraulic power, the operative manoeuvres the arms around the pipe and then applies sufficient pressure to crack the pipe. The MACAW may be used on cast iron pipes inserted with PE if required.

Benefits of using a Steve Vick International MACAW Cracker

  • Safer and faster than using a ‘podger bar’ or sledge hammer
  • Does not require access around the whole circumference of the pipe
  • Controlled pressure applied – suitable on abandoned and inserted mains, without damaging internal PE
  • Easy to operate—highly manoeuvrable
  • Various power source options available to accommodate site conditions
  • Quick set up
  • Ideal for use with Live Mains Insertion
