ROTO HDPE

WATER PIPES;

ROTO HDPE is made of High Density Polyethylene (HDPE) plastic material for the manufacture of High Pressure Pipes are renowned worldwide for its reliability, The Characteristics that makes it outstanding are its toughness, its resistance to chemical attack and its immunity to weather conditions. This makes it an excellent material to convey.

ROTO HDPE Pipes are manufactured and confirm to international standards DIN 8074. The Dimensions are based on ISO/R-16-4427.

ROTO HDPE Pipes are available in 20 mm diameter to 500 mm diameter and Class (Pressure Rating) PN-8, PN-10, PN-12.5, PN-16, PN-20, PN-25 with complete range of fitting

Note Pipes size 20MM – 500MM can be manufactured as per Customer Requirements

a=PN value are based on C = 1.25

b=The calculated value of emin according to ISO 4065 is rounded up to the nearest value of either 2.0, 2.3 or 3.0       This is to satisfy certain national

.requirements. For practical reasons, a well thickness of 3.0mm is recommended for electro fusion joining and lining applications

c=Actual Calculated values are 6.4 bar for PE 100 and 6.3 bar for PE 80

1 bar = 0.1 MPa; 1MPa=105a; 1MPa = 1N/mm2
