What is pipe? Each hollow cylinder can be called a pipe, but any hollow cylinder is pipe? Theoretically, following definition can be used for pipe: pipe is a hollow cylindrical pipe which is used for transfer or store of liquids, gases, and fluid substances. Pipe has been one of the best and most important inventions of humans, which has developed throughout history. pipes can be made from various materials such as iron (cast iron, galvanized sheet metal), steel, polyethylene and all types of plastics, glass, concrete and cement, etc. (and many other materials).
Pipe industry never ceases, and it only turns into from one form to another form, and development of this strategic product will continue. Production of all kinds of pipes varies according to gender and applications. Polyethylene pipes and metal pipes, and after that, the PVC pipe, is most used. Pipes are available in a wide range of sizes. It's not unusual at all that we have pipe with size of 1.2 inch and 66 inch high.

Gas pipe as an element of infrastructure and urban and rural facilities have great importance. In urban and rural communities and wherever human live, presence of gas is one of the development pillars and progress of that society. Gas distribution is carried out in areas by gas special pipelines, which must have special specifications and comply with certain standards.
We have relatively stable conditions in selecting of gas pipelines, and choice of the pipe is different from internal gas pressure and pipe size. In main gas pipelines use carbon steel pipes, and in urban and rural divisions, and branches of consumption, Polyethylene pipes are best choice for best type of gas pipe.

Safety factor (SF) can be 1 (1.25), 1.6 or 2. Safety factor is indicator of ensure from life span of polyethylene pipe. By increasing of SF, resistance of polyethylene pipe increases at pressures above specified limit. SF of polyethylene pipe is one of characteristics that is presented in the specification table. SF of polyethylene pipe Which is presented in the national standard of Iran, as well as the German DIN standard and all the standards of the PE pipe in the world, is indicator of ensure from life span of polyethylene pipe.

Raw material for corrugate two- wall polyethylene pipe of Pars Ethylene Kish is from Natural Polyethylene or White Polyethylene. These pipes are double-layered, and both layers are from polyethylene materials, and should be base materials of their polyethylene from polyethylene material and with completely homogeneous formulation, and this coordination in detail is due to the fact that layers of the corrugate pipe are produced in two separate extruders, and finally, in corrugator section, pipe line is welded together. Polythene materials must be homogeneous for reliable and strong fusion points. For example, cannot be used for outer layer from natural polyethylene material of Maroon factory and for the inner layer from white polyethylene material factory Shazand, and both polyethylene materials must be from a factory and with similar formulation.

Sewage Manhole ! Every time we talk about the manhole, everyone thinks about the sewage, because first and greatest application of manholes is in sewage system, but use of manholes is not only in sewage system, and in all underground channels that we want to access, Manhole is mandatory.
When we talk about sewage system and its associated systems and sewage network equipment, we have to think quickly about its durability and its longevity, and its resistance to sewage, and next issue is the type of sewage, and suspended solids in sewage must be specified.

Application of polyethylene fittings are extensive , like polyethylene pipe. Polyethylene fittings are used in all applications of polyethylene pipes and all polyethylene pipelines. Use from polyethylene fittings depends more on the type of line and type of project, For example, flange fittings cannot be used in gas pipelines, or from electrofusion fittings cannot be used in water transmission lines, and use from them is wasting of financial resources.

Technical specifications and quality of double wall corrugated pipes must be in conformity with DIN 16961-2 standard (relevant to dimensional control and ring stiffness of the pipe) and EN13476 (other tests regarding the quality specifications of the product).

Producing polyethylene fittings is a bit harder than producing polyethylene pipes and requires different welding equipment and machinery for manufacturing the polyethylene fittings and also the operators of the welding machines need to be trained and skilled in manufacturing of all kinds of polyethylene fittings.
The production of polyethylene fittings consists of a simple, time consuming but precise process. The polyethylene pipe which is produced before and is of high quality in and conformity with the required standards are selected and cut into required pieces using special saws and if any angles are required at the top of the pipes, they have to be created by the saws.

HVAC Applications is one of the chapters in the Plastics Pipe Institute’s PPI Handbook of Polyethylene Piping. Other topics to be addressed in the handbook will include design of polyethylene piping systems, joining procedures, engineering properties, directional drilling and a variety of related information.The PPI Handbook of Polyethylene Piping is being produced by the Municipal and Industrial (M&I) Division of PPI. M&I membership consists of major North American manufacturers of polyethylene (PE) pipe and fittings, PE piping materials, machinery, and equipment used for joining and installing PE piping, related test laboratories, and professional organizations.

The polyethylene pipes were being produced with pipe grade polyethylene which is known as PE 100 , PE 80 and PE 63 and supplied to the market, the only difference was in density and concentration. Nowadays, with the developments in the technology and higher standards only the PE 100 grade is remaining and the other grades have been put out of the production cycle.

PE 80 materials, as its name suggests, have less density than PE100 polyethylene materials and therefore, PE 80 polyethylene pipes are both heavier and thicker.
According to the standards, PE 80 polyethylene materials are currently used most in production of corrugated double wall pipes and some of the manufacturers of polyethylene pipes still use PE 80 grade materials for production of huge sized and under pressure pipes which is a mistake and in both long term and short term will sustain a loss to the consumers.

MDPE pipe is used for cold water mains into new builds and to replace old lead water supplies into both domestic and commercial properties.
Medium Density Polyethylene as it is fully known, (or blue poly as it is regularly called in merchants) is a durable, seamless pipe suitable for delivering high pressure mains water from the main run, into properties and can be used for replacing existing lead water main pipes.

The method of repairing damaged PE pipe depends upon the degree of damage sustained. Localised damage may be repaired by use of an electrofusion saddle or clamp fixed around the damaged area. Such a repair may not be suitable where gas or other flammable fluid is present in the pipe, due to the heat generated in the fusion process. PE encapsulation techniques have recently been developed and may be suitable for localised repairs. Information on these techniques can be obtained from the pipe manufacturers.

The differences between PVC and HDPE lie both in the applications for each and their composition. While PVC is the more common of the two, high density polyethylene is used in specific circumstances that make polyvinyl chloride unattractive or unsuitable. PVC is a relatively inexpensive and fairly durable vinyl polymer. High density polyethylene is a thermoplastic made from petroleum. Both PVC and HDPE are considered plastics.

The best brand of polyethylene pipe is a polyethylene pipe which has full information about the whole pipe manufacturing process, as well as full confidence of the raw material used in it. The best brand of polyethylene pipe should have a series of features. The pipe must have a standard mark and the pipe should have been manufactured in accordance with 14427-2INSO standard.

If we want to describe the PE100, PE80, and PE63 polyethylene grades in a simple and general sentence we should know that the PE63 means that the intended polyethylene pipe is capable of tolerating water transfer at a temperature of 20 ° C under pressure of 63*10^5 Pascal, that is 63 atmospheres for 50 years. Or when we say that the PE80, we mean that the intended polyethylene pipe is capable of tolerating water transfer at 20 degrees Celsius under pressure of 80 atmospheres for 50 years, and the same for PE100.

HDPE and LDPE are two common elements of polyethylene. As we know there are several types of polyethylene; these two types of polyethylene have a special position and have many applications in the industry.

The molecular structures in various types of polyethylene, as well as in heavy HDPE polyethylene and light LDPE polyethylene, affect their behavior. By decreasing the branching of polymeric chains and molecular mass in them, the crystallinity of these polyethylene increases, and density and crystallinity are also directly related.

HDPE pipe is simply a pipe made of polyethylene; this material gives the pipes some special features which creates benefits and these advantages have led to the popularity of polyethylene pipes.
HDPE pipes have many advantages, high quality, reliability of pipe and fittings, ease of loading and transportation of pipes and fittings of polyethylene due to their relatively low weight, quick and easy installation have made polyethylene types the best choice for various projects.

Polyethylene pipes are capable of transporting drinking water, sewage, chemicals, slurries and hazardous wastes and gases. Nowadays, the use of HDPE pipes in the water supply networks is growing and managers of executive projects use polyethylene pipes instead of other types of pipes in most cases. The strength and durability and ease of installation of polyethylene pipes and polyethylene Fittings have are effective in this decision making by executives.

Polyethylene is a kind of thermoplastic polymers, which means that it turns into liquid by reaching its melting point and turns into solid by reaching its freezing point. Polyethylene is a chemical synthesis of ethylene, usually made up of a mixture of crude oil and natural gas. Polyethylene is widely used in the production of all kinds of plastic accessories used in the kitchen and food industries.

Polyethylene pipes ( HDPE Pipes) are produced at different work pressures (PN), and this work pressure (PN) is tolerable for pipes at temperatures of 20 °C. This temperature is best for polyethylene pipes. Various types of pipes have different PN grades and also different wall thickness, which is why the strength, power and flexibility of pipes are varied. Hence, the higher the PN, the greater the thickness of polyethylene pipe....

In 1958, the global polyethylene production reached 17,000 tons a year and in 1962 it reached 200,000 tons per year, and various licensed polyethylene production at low temperatures and low pressures was granted in nineteen different locations in Europe and seventeen in the United States and Japan. At present, around 28 million tons of polyethylene are produced annually in the world, of which about 4 million tons are used to produce various types of polyethylene pipes.
