PE PIPE DIMENSION

Polyethylene - PE - is popular and and commonly used material in water pipes. It is usual to use the PE 50, PEH or PE-HD (polyethylene high density) quality.




PE pipes are produced in different pressure grades - PN grades - indicating the pressure in bars the pipe can support with water at 20 oC.



The pressure grades available according to European standards are



PN 2.5 - max pressure 2.5 bar

PN 4 - max pressure 4 bar

PN 6 - max pressure 6 bar

PN 10 - max pressure 10 bar

PN 16 - max pressure 16 bar

1 bar = 105 Pa (N/m2) = 0.1 N/mm2 = 10.197 kp/m2 = 10.20 m H2O = 0.9869 atm = 14.50 psi (lbf/in2) = 106 dyn/cm2 = 750 mmHg

Polyethylene Pipe Systems

 

Polyethylene (PE) pipe manufacture commenced in Australia in the 1950's where small diameter pipes were used for rural, irrigation and industrial applications.

Since then PE use has grown enormously, due to the advantages it offers over iron, steel and cement systems. It is free from corrosion in all ground conditions and its flexibility allows it to withstand ground movements. No protective layers or finishes are required.

PE's  resistance to ground instability means that PE gas and water systems were the only systems to survive the major earthquakes in Kobe, Japan in 1995. PE systems can be fusion welded so there is no risk of leaking from joint distortion. Costly anchorage is not required at junctions and bends. Root penetration is not a problem. PE's low friction bore is not subject to scale buildup

PE's flexibility allows cost savings during installation, and PE can be coiled to be supplied in long lengths, reducing the cost required for joints and fittings. Cost saving installation techniques take advantage of its flexibility and low weight, reducing disturbance to the public and environment. Trenchless technology can use PE by pulling long lengths through holes below ground bored by mechancial moles, avoiding the need for open trenches. PE is often used in renovation of old pipelines as it can be readily inserted as a lining into an old leading pipeline.

 

PE fittings complete the PE pipe system which has a high track record of reliability over a long period. A commitment to using only the highest standard of raw materials and the latest manufacturing technology has established Vinidex with a reputation as a quality supplier of Polyethylene Pipes in sizes ranging from 16mm to

Advantages Of Polyethylene Pipe

In US polyethylene hdpe pipes are getting popular due to its high quality, easy maintenance and durability. Pipes fitted in homes and buildings often show signs of pipeline corrosion due to high humidity and soaring temperatures. However, in case of polyethylene pipe you can stay out of such troubles, since these pipes are made with special materials to avoid such corrosion.

In case of normal metal pipes such corrosion with force you to spend on repairing these pipes frequently. But then with polyethylene hdpe pipes this is not a problem. These pipes have higher resistant power. Thus, you can use HDPE pipes for years without facing the trouble of either replacing it or repairing it. If you have a factory of your won or are planning to build one, you can use polyethylene pipe to enjoy years of hassle-free service as these pipes help to avoid domestic or industrial pipeline problem.
HDPE pipes are durable and flexible in nature. Thus, by installing HDPE pipes you can get long-term service with spending anything extra on repair. So, what makes these pipes durable and resilient? It is the advanced technological engineering put into the development of these pipes. In order to manufacture HDPE pipes and polyethylene liner Process Intensification or PI technology is put to use.
So, why is the benefit of Process Intensification [PI]?
Through PI technology you can enjoy certain advantages:
1. Develop the reaction rate.
2. Reduces consumption of energy.
High Density Polyethylene pipe helps to lessen the wastage of energy. Moreover, you can reduce expenses as well. Again these pipes are weather resistant and this very quality is rendered due to the PI technology. In US and several countries all over the word face extreme weather condition ranging through the year. Hence, if pipes are unable to ensure such tough weather conditions, they will either form leakage or breakdown.
How to install HDPE pipes?
HDPE pipes are installed with the help of high quality polyethylene liner or pipeline liner.

Advantages of polyethylene hdpe pipes:

There are several advantages of HDEP pipes. They are weather resistant, durable, flexible, and cost-effective in the same time. Most of these pipes are custom built. Thus, these pipes can be easily created based on your request. You can even select the size of these pipes according to the measurement of your building. Once that is done, proper fusion of pipeline liner is completed to shield the fusion process.

After the fusion is done, this follows with the condensing of polyethylene liner. The size is comparatively small when compared with host pipe diameter. Hence, HDPF Pipes enjoy he flexibility and they can remain rust free during monsoon, expand in summer and compress during the winters.
Apart from the above there are other features of HDPE pipes. With these pipes you can remain in peace without getting troubled of water clogging and floods.
If you wish to have a trouble free and hygienic life, make sure you install polyethylene pipes. Once you replace your metal pipes with HDPE pipes you can watch the difference.

Using HDPE pipe for drainage problems.(high-density polyethylene pipe)

he Corrugated Polyethylene Pipe Association (CPPA) recently held a "Send Us Your HDPE Pipe Stories" contest. The following winning entries described unique and/or innovative applications, as well as stormwater drainage installations in which high density corrugated polyethylene pipe (HDPE) solved a specific problem.

FLAT LAND LEADS TO FLOODING

Several homes along Forrest Drive, a residential street in North Pekin, Illinois, near Peoria, suffered serious flooding during periodic heavy rains. The land along the drive was flat, and the village's old ditch-and-culvert drainage system was incapable of handling even 1.5 in. of rain, creating frequent floods for area residents.

INDUSTRIAL AND CHEMICAL

INDUSTRIAL AND CHEMICAL

Corrosion resistance and resistance to attack by many industrial chemicals make plastics pipes the obvious choice for chemical plant installations. Like with all materials used in the construction of chemical plants care must be taken in selecting the correct plastics pipes and fittings that will withstand the operating conditions.

The wide range of polymers used in manufacture of plastics pipes and fittings provide a good range of products from which to select the appropriate material. PVC piping systems are widely used in water, wastewater and chemical transfer. Polyethylene piping systems are well suited to installation in difficult industrial situations. Their high strength and ease of installation also makes them ideal for compressed air reticulation

AGRICULTURE, IRRIGATION & DRAINAGE

AGRICULTURE, IRRIGATION & DRAINAGE

A variety of alternatives to PVC are used both for water delivery and for drainage. Irrigation sprinkler, drip and drainage systems have long been available in HDPE and have significant advantages in resilience against compression, shovel attack and ground movement. Corrugated steel, concrete and HDPE are all competitive alternatives for drainage. HDPE drainage pipe is now available in formulations with high-recycled content. Plastic pipe has carved a hunk of the huge market previously dominated by concrete and steel. Highway drainage is a fast growing market for HDPE. Recently, the Corrugated Polyethylene Pipe Association initiated a third party certification system, which allows for increased acceptance of their product by the American Association of State Highway and Transportation Officials. Footing and under slab drains are all available in HDPE.

AGRICULTURAL AND RURAL

Water is a lifeline for all farming operations and the security of water is essential. Plastics pipes are available for the wide range of farming applications. Pressure pipes for irrigation, plant watering and potable water reticulation. Non-pressure pipes for irrigation, stock watering, micro-irrigation and general water reticulation systems.

Low cost, wide range of pipe sizes, flexible and easy to handle and transport are all advantages important to the farmers.

PLUMBING

PLUMBING

PVC pipes and fittings for plumbing and drainage applications is the choice of plumber’s word wide. Low cost, lightweight, long life expectancy usually for the life of the installation is the overwhelming advantages. PVC does not corrode internally or externally eliminating the possibility of pipe failures or blockages. Cross-linked polyethylene, polypropylene and Polyethylene pipes are used in hot and cold-water reticulation in domestic, commercial and industrial installations. Ease of installation using compression fittings is providing a cost advantage.

Polyethylene, like other plastics, has a thermal coefficient of expansion higher than metals. When subjected to a temperature change, unrestrained (not buried) polyethylene pipe will experience expansion and contraction.

The coefficient of thermal expansion/contraction for Polyethylene is 1.0 x 10-4 in/in/°F. As a general allowance, 1" per 100' of pipe per 10°F change in temperature.

Forces due to thermal expansion and contraction can be significant. Proper system design should be used to account for the compressive and tension stresses that can be generated.

When pipe is used in pressure applications, the longitudinal stress created by the sum of the bending radius, internal pressure and other stress loads on the pipe should not exceed the material’s design stress rating. Severe but acceptable bends in polyethylene pipelines should be buried or properly restrained.
