Dorina Engineering

Our Products

01

Borehole Submersible Pump

Robust stainless steel structure guarantees long-lasting and failure-free operation. The pumps are available with 4” up to 8”inches in stock. Reliable structure and very high parameters compared to the diameter of the pumps make them have a wide application from feeding large farms to solutions in the industry.

02

Solar Pump Inverter

The solar pump inverter converts the DC power of the solar array into AC power, which can drive various pumps and provide clean water for remote areas where power facilities are scarce. Although the solar water pump inverter accounts for a small proportion of the cost of the solar pump system, it is the core equipment of the system

03

HDPE Pipes

HDPE pipes are used widely in potable water supply and distribution, sewerage and drainage, irrigation and gas transportation and distribution and telecommunication.
HDPE pipes have been found to be very reliable and proven high performance in these areas. It is the preferred choice in installing pipes of several kilometres since current methods of jointing (such as butt-welding, electro weld joints and compression fittings) ensures zero leak rate. 

HDPE pipes supplier Dorina ranges from 32 mm to 160 mm in diameter for water supply, Irrigation, and drainage system for Engineers and other users to choose from. The Smaller sizes are available in coils whilst the bigger ones are cut to pipe lengths (e.g. 6 m, 9m & 12 m).

Dorina HDPE pipes are produced in accordance with existing international and national standards
and norms in the countries. The main international standard followed is ISO 4427.

UPVC pipes

Polyvinyl chloride is a thermoplastics material, which consists of PVC resin compounded with varying proportions of stabilizers, lubricants, fillers, pigments, plasticizers and processing aids. The PVC compounds with the greatest short-term and long-term strengths are those that contain
no plasticizers and the minimum of compounding ingredients. This type of PVC is known as UPVC or PVC-U. 

PVC-U (un-plasticized) is hard and rigid with an ultimate tensile stress of approximately 52 MPa at 20°C and is resistant to most chemicals. Generally, PVC-U can be used at temperatures up to 60°C, although the actual temperature limit is dependent on stress and environmental conditions. PVC pipe is manufactured by extrusion in a variety of sizes and pressure rating. PVC pipe is made usually to confirm to ISO or DIN standards for both pressure and non-pressure application. Polyvinyl Chloride (PVC) piping is the most widely used plastic piping material PVC piping systems are:

  • Environmentally sound
  • Provide long service life
  •  Easy to handle and install
  •  Cost effective
  • Free of corrosion

uPVC (un-plasticized polyvinyl chloride) pipe have a high strength to weight ratio and exceptional
resistance to corrosion and chemical attack. They are used in many applications, including:

  • Potable water supply and distribution
  • Industrial process water systems
  • Irrigation systems
  • Sewer rising mains
  • Drain waste water
  • Conduit
  • Process and effluent discharges in the plastics, chemical, food, dairy and alcoholic beverage
    industries.
