MDPE Pipes

ISO:4427, ISO:4437, & IS:14885

Inherent characteristics of MDPE such as corrosion & crack resistant, tough and flexible makes Polyethylence piping systems the most preferred means  of transportation and distribution of water, petrol and natural gases world wide.

MATERIAL:

The raw material used is Medium Density Poly Ethylene (MDPE). Tijaria /Vikas Pipes manufactures pipes in grades PE-80 & PE-100 for gas applications in sizes 20 mm to 250 mm (Outer Diameter) in all pressure ratings. Traditionally these pipes are identified by its color for different uses like blue for water, orange for petrol, and yellow for gas lines.

SPECIFICATIONS:

Tijaria/ Vikas Pipes manufactures MDPE pipes which confirms to national and international standards as ISO-4437, ISO-4427 , IS-14885, BS-7281, DIN-8074/75. Tijaria/ Vikas pipes can also be tailor made to meet the specific requirement of individual gas authorities or customers.

 

SALIENT FEATURES:

  • Flexible                         : Easy to Handle
  • Corrosion Resistant        : Tough and highly reliable in aggressive soils.
  • Fusion Joints                 : High Integrity and reliability
  • Light Weight                 : Lighter in weight as compared to metal pipes.
  • Crack Resistant             : Excellent resistant to subsidence, traffic vibrations point leading and marshy ground.
  • Homogenous                 : leakage free joints.
  • Installation                    : low Installation cost.
