uPVC PIPES & CASING PIPES
     
  When infrastructure investments such as pipeline systems are made, foremost consideration is given to the reliability of the finished system and the engineering expertise that goes into every facet of the project. Desirable characteristics such as product strength, weight ratios, design simplicity, ease in installation and maintenance as well as manufacturing quality is revealed only under adverse conditions or overtime.

Unplasticised Poly vinyl Chloride, uPVC has been proven to be one of the most resilient materials for water and other applications. uPVC has almost replaced the conventional Copper & Steel pipes due to the various advantages at an economical cost. Coupled with its value for money, uPVC has now become the material of choice for virtually all applications such as Water distribution lines, Sewage, Irrigation, Plumbing, Conduit, Boreholes, etc.

Since its inception, Holborn has adhered to the most stringent international quality standards and specifications, both in its operational systems as well as product formulation. The natural consequences of complying with ISO 9001:2008 quality standards gained Holborn this prestigious certification. The Holborn products conform to many international standard such as BS, DIN, ISO and ASTM.
 
   
 
Physical Properties:
 
Resistance to Corrosion :
uPVC pipes exhibit excellent resistance to almost all types of corrosion, either chemical or electro chemical in nature.
Non-toxic :
Being made of odorless material, uPVC pipes remain neutral to all transported fluids.
Minimum Flow Losses :
Due to smooth inside surface, uPVC pipes have minimum flow head loss and no buildup of inside deposits.
Resistance to Weather :
 
 
 
 
 
 
  uPVC pipes are not affected by direct sunlight, wind, and rain. But it is recommended that the pipes be protected from sunlight to avoid degradation due to long exposure to direct sunlight.
Fire Proof :
  uPVC is not conductive to combustion. Should there be fire, flames are unable to travel on uPVCpipes. It is an added advantage when used for electrical installations, both industrial and domestic.
Light Weight :
  uPVC pipes are light in weight compared to other pipes. This reduces transportation costs and facilitate installation in difficult places.
