Catalogue of Manhole

Polyethylene Manhole is a new product of Pars Ethylene Kish which is manufactured of finest raw material with best design, compared to similar samples. This product has wide range of application such as oil, gas and petrochemical industry, power plants and urban transmission pipelines. .Poly Ethylene products, such as polyethylene manholes, instead concrete one , polyethylene pipe in lieu of PVC pipes are those which are make the quality of installation perfect and faster.
Pars Ethylene Kish manholes have the best Polyethylene raw material and best design compared with the similar ones. 

 All content of this installation guide is taken from ASTM1759, HDPE Manhole ISO13272 and ATV127 standards which the first two standards are the basic national standard of Iran and the ATV standard has been used in order to calculate the installation, sort of backfill and data bases used in projects. Materials used in the production of Pars Ethylene Kish Company’s manholes are from polyethylene material with 3840 grade and also it can be used from HDPE or LLDPE materials with rotary molding grade for producing polyethylene manhole .installation and implementation, But also during the production and design issues of manhole in order to supply a reliable, long life production. 

 Materials used in the production of Pars Ethylene Kish Company’s manholes are from polyethylene material with 3840 grade and also it can be used from HDPE or LLDPE materials with rotary molding grade for producing polyethylene manhole .

Pars Ethylene Kish Polyethylene Manholes have a unique advantage, and this is the modular advantage of polyethylene manholes produced by this company. This definition means that the manholes of Pars Ethylene Kish are not a fragment and consist of different parts with different uses, which allows designers and implementers to freely and unrestrictedly choose their manhole height and diameter. In prefabricated manholes for the first time, it is possible to see the possibility of producing polyethylene manholes, and the modularity of the Pars Ethylene Kish manholes with the design and construction of modern rotary moldingmachines and precision molds that were carried out by Pars Ethylene Kish specialists and has finally been approved and certified by the Iranian Bureau of Standardization.

The method of single pipe parietal connection into the polyethylene manhole.
As it can be seen in figure 1, polyethylene single pipe parietal connection to polyethylene manhole must be done so that a complete seal occurs.
n order to reach standard conditions for polyethylene single pipe parietal connection into the polyethylene manhole, the exact place of interior and exterior parts must be determined and before the installation, the interior and exterior parts must be drilled on manhole frame. 

Production of polyethylene manholes is not the sole construction and commissioning of rotary machines for producing or procuring raw materials. Designing and calculating and how to make molds, analyzing and evaluating the manhole's body resistance is of great importance. Therefore, Pars Ethylene Kish has analyzed all the designs and drawings of molds and manholes before making and analyzing them and simulating actual conditions and introducing various types of traffic pressures and dead and live loads like those designed for special applications, strength, durability and precision of products, Pars ethylene Kish manholes are resistant and defective in any way.
Here is some of these calculations. Contact the engineering unit or sales expert at the company for a full version of the calculations.

Sewage network Contains, sewage transfer Networks, Polyethylene Manholes, Pumping Stations and refinery.In This matter manholes to be used for Inspection and supervision of sewage networks and installed in specified distance.
As the importance of manholes in the sewer network review of their qualification and determinate the performance is a very sensitive issue.
the construction of GRP manholes are resin, polyester and gravel , therefore to reduce the price of GRP manholes in combination increase the amount of gravel.So the friability of manholes proliferate , It Also can be used inferior resin to decrease ,The Price too

The polyethylene manhole production process involves five steps, making the pattern, making molds, melting materials, pouring materials and finally cooling. Polyethylene manhole production line of Pars Ethylene Kish is one of the most advanced and newest manhole production equipment in the world. Pars Ethylene Kish manholes are designed according to different needs and uses, and are national and international, and are produced using rotary molding technology (rotary molding).
The raw material is granular, which is initially converted to a powder by a pulverized mill with a special roller for the production of powder from polyethylene materials, and after the special molds attached to the rotary machine arms, was poured into the mold. Afterwards, the molds are rotated in a rotary kiln under high temperature and under precise time control, and after the exact time of heat shrinking, and at the end of the cooling process, the process is carried out.

Polyethylene raw materials in the production of polyethylene of manholes in Pars Ethylene Kish are made of polyethylene materials with a grade 3840 for rotary molding of Tabriz petrochemical products. Polyethylene 3840 produced by Tabriz refinery has anti-UV additives and does not need to add other resistant materials such as carbon black and in contrast to direct sunlight, they are resistant to the standard. The MFR index, or the same molten flow index, is 4 and the density of this type of polyethylene is 0.938.
