SolidWall Pressure Pipes

KAI Pressure Pipes are produced with pressure ratings ranging from PN4 to PN25. KAI Pressure Pipes PN4 can be used for drainage while the higher pressure classes are used for pressured fluid systems

Advantages and Applications

Advantages

Jointing Techniques

As a thermoplastic material, HDPE is highly suited to welding techniques, providing a 100% leak free joint with no interface material.

KAI Pressure Pipes can be jointed by butt welding and electrofusion welding.

BUTT FUSION

Butt welding (or butt fusion) is a simple and quick jointing method to connect pipes and fittings of PE. The process starts by cutting the pipe ends straight and cleaning them carefully. A heater plate, the temperature of which is 210-230degree Celsius, is then placed in between, and the ends are heated for a certain time, initially under pressure and then without pressure. The polyethylene becomes soft and a so-called bead is formed at the pipe ends. The heater plate in then removed and the pipe ends are pressed together and allowed to cool under pressure. This will form a welded joint that is water tight and homogeneous.

ELECTRO FUSION

This jointing method is utilized for jointing pipes as ell as fittings of PE. This is an easy system where preinstalled resistance wires on the inside of the fittings are slightly coated with PE. When these wires are connected to a welding unit , they become warm and the polyethylene consequently melts. Having the ends of the pipes in the connection of fitting (socket,bend etc.), the polyethylene then melt into each other and form a rigid and durable joint. This jointing method is very common for gas pipes and potable water pipes. A welding unit is available for this procedure and makes the whole operation very easy and practical.

Laying of Pipes

LAYING OF PIPES

KAI Pressure pipes offer a distinct weight advantage compared with other piping products:

  • Polyethylene pipe is produced in straight lengths up to more than 12m long and coiled in diameters up through 110cm. Coiled lengths up to 300m are available
  • The combination of flexibility and leak free joints allow for unique and cost effective types of installation methods that the rigid PVC and Ductile Iron pipes can’t use with bell and spigot connections. These alternate installation methods (Horizontal Directional Drilling, Pipe Bursting, Slip-lining, Plow and Plant, Submerged or Floating Pipe etc.) can save considerable time and money in most potable water and sewage applications.
  • Polyethylene is about one-eighth the density of steel pipe, it does not require the use of heavy lifting equipment for installation.
  • Natural snaking property reduces use of fittings for direction changes.

The following specifications apply to the laying of KAI Pressure Pipes:

  • The trench foundation should be smooth, stable and free from roots, rocks and other sharp objects.
  • The height of bedding should be 150mm ad should consist of soil classification as ASTM D 2321 type II SP compacted to 90% DPr (Degree of Proctor).
  • Haunching and back filling soil type is the same as used for bedding and soil should be placed to successive lift of 150mm and compacted to 90% DPr.
  • Height for final back fill – 300mm

Connection to Other Pipes

HDPE Pipes can be joined with various types of pipe materials including steel, grey cast iron, ductile iron, asbestos cement, uPVC, GRP, concrete, polythene and ABS.

Fittings like couplings, stepped couplings and flange adaptors are used to join pipes of same/different materials and having same/different outside diameters.

This eliminates the need to replace the old existing piping system with HDPE piping system at a go, distributing the cost of replacement over a period.

HDPE pipes have replaced galvanized & polybutelene pipes as the preferred material for house connections.

Water is tapped from the mainline using a tapping saddle clamp and connected to a HDPE pipe servicing the house. A typical house connection is illustrated below:
