KRAH Manholes and Chambers

Thermoplastic Manholes and Chambers have been successfully used for decades around the globe, and as well as in the Sultanate of Oman. United Gulf Pipe Manufacturing Co. LLC (UGPM), located in Rusayl Industrial Estate was established in the year 2009 in Sultanate of Oman with a vision of becoming one of the solution providers and the market leader in GCC by producing and supply of thermoplastic pipes and other associated products using KRAH Technology. Advantage of this technology is, the profile or the structure section can be optimized to give an increased load bearing capacity and a lower weight compared to solid wall pipe of similar load bearing capacity.

With the KRAH production line either a solid wall or profiled structural shafts are helically extruded cylinders can be produced in all diameters up to DN/ID 3000 mm and a length of up to 6000 mm. Being robust in design and light in weight, easy handling, makes the installation possible in very short time. UGPM tanks are always a smart solution to complete the projects in time.

General Design

Manholes or Chambers are tailormade for the network. The shafts for the manholes or chambers are designed to withstand hydrostatic pressure due to ground water, and the radial loads due to soil and live loads considering and other conditions. The static design of the vertical shafts is mainly according to the international accepted standards ASTM F1759 and ATV 127.

To facilitate the calculation, KEPM uses a special software program “Easy Schacht”, where all conditions like ground water, traffic loads are considered to calculate the optimum structure. The wall thickness is designed to according to the static requirements and due to the helical extrusion technology of KRAH, the wall is completely monolithic and homogeneous.

Application

  • House Connection Chambers
  • Manholes for sewer and storm water network.
  • Lifting Station
  • Pressure breaker chambers
  • Vacuum Valve chambers

Production Technology

KRAH Technology is used to manufacture large diameter cylindrical shafts with the helical extrusion technology, which gives a reliable, safe solution with high quality in its construction.
The combination of the transverse movement of the extrusion head along with the rotational movement of the mould forms the helical winding of the molten material. The material being molten the jointing between the layers while forming the helix is homogeneous. The manufacturing method involve the helical extrusion on a mould or mandrel, thereby a seamless cylindrical shaft is produced, no frozen stress in the wall.
The benching’s for the manholes or chambers are thermoformed using HDPE sheets from PE 100. The various components are then assembled and joined together by extrusion welding.
The materials used to manufacture tanks is HDPE with excellent corrosion resistant properties, being chemically inert to most products.
