HORIZONTAL DIRECTIONAL DRILLING SERVICES

 
  • Horizontal Directional Drilling

  • Horizontal Boring

  • Rock Drilling

  • Pipe Bursting / Cracking

  • Site Visit and Survey

  • Diameters of 63mm to 900mm

  • Distances from 10m to 300m

Horizontal Directional Drilling (HDD) is an innovative technique that can be used to install underground utility pipes, ducts or cables in straight or curved line without damaging surface layers. Services may vary due to different soil conditions where solutions can be provided such as rock drilling. HDD can be considered as an alternative to Pipe Jacking.

Unlike traditional trenching methods that is most of the time far more costly and not practical, HDD is a trenchless form of drilling that is faster, cleaner and less disruptive. Open trench can result in damage to the infrastructure that costs millions of Rands.  In contrast, HDD is far less invasive, has a much quicker turnaround time and is eco-friendly to the environment.

Benefits of horizontal Directional Drilling

Saves time and labour of digging for open trenching

Reduces costs of labour and traffic control expenses.

Limits the risk of damaging existing underground services. 

BUTT FUSION WELDING SERVICES

 
  • Butt Fusion Welding

  • Site Visit and Survey

  • Welded to Various FIttings

Butt fusion jointing is a thermo fusion process which involves the simultaneous heating of the ends of two components which are to be joined until a melt state is attained on each contact surface.  The two surfaces are then brought together under controlled hydraulic pressure for a specific cooling time and homogeneous fusion is formed upon cooling.  The resultant joint is resistant to end thrust and has comparable performance under pressure to the pipe.

This method of jointing requires an electrically heated plate to raise the temperature of the pipe ends to the required fusion temperature and is used for PE63, PE80 and PE100 grades of material for pipe of size 32mm and above of the same Standard Dimension Ration (SDR).  When joining pipes using butt-fusion techniques, the heater plate temperatures are the same for PE63, PE80 and PE100, raising to the degrees of 195°C to 220°C.
