About HDPE Pipes
VAJJERAMPLAST High density polyethylene pipe has been used extensively around the world
since the 1950's.The unique properties of High density polyethylene pipe have offered an alternative
to traditional material like steel and copper and also in non pressure applications where clay and
fibre cement pipes were used.
The material has been developed internationally from PE B0 to today's PE 100 material which has
shown a saving of approximately 30% on the wall thickness from the early days of Polyethylene. This
mass saving relates back to a cost saving and a better performance as the internal diameter of the
pipe is bigger. In many cases, because of the excellent flow characteristics of Polyethylene, pipes
could be down sized while still performing within the expected parameters. The pipes' properties
such as impact resistance and resistance to abrasion have made HDPE pipe the obvious choice in the
Mining and Industrial markets. Piping made from polyethylene is a cost effective solution for a broad
range of piping applications in the municipal, industrial, marine, mining, landfill, duct and agricultural
industries. It has been tested and proven effective for above ground, surface, buried, slip-lined,
floating and sub-surface marine applications. High-density polyethylene pipe (HDPE) can carry
potable water, wastewater, slurries, chemicals, hazardous wastes, and compressed gases. In fact,
polyethylene pipe has a long and distinguished history of service in the gas, ail, mining and other
industries. It has the lowest repair frequency per kilometre of pipe per year compared with all other
pressure pipe materials used for urban gas distribution. Polyethylene is a strong, extremely tough,
very durable product which offers long service and trouble-free installation.
HDPE | Parameters of Comparison | MDPE |
---|---|---|
High-Density Polyethylene. | Full-Form | Medium Density Polyethylene. |
HDPE has a high density of about 0.914g/cm3. | Density | MDPE has a low density of about 0.926 to 0.940 gm/am3. |
HDPE is highly sensitive. | Sensitivity | MDPE is comparatively less sensitive. |
HDPE has low resistance to stress cracking. | Stress Cracking Resistance | MDPE has a higher resistance to stress cracking. |
HDPE has the most minimal branching. | Branching | MDPE has minimum branching, too, but a little higher than HDPE. |
VAJJERAMPLAST HDPE material has a high degree of impact resistance and is robust and ductile. Pipes can bend quite easily allowing for savings in design as less critical angle changes can be made without bends. HDPE pipe can be made without bends. HDPE pipe can be laid across uneven surfaces and in narrow trenches. The Pipe can be joined outside of the trench before installation into the trench. The ability to absorb pressure surges makes the products superior to other plastic pipe materials. Even in sub zero temperatures, HDPE can still perform expectation.
The rated working pressure of an HDPE pipe is determined at 20°C, the pressure rating of the pepe has to be de-rated in order to maintain the desighed safety applications where the fluid temperature exceeds 50°C
