Manufacturers of pe and HDPE pipe are in an intense competition to offer a lower prices with improved specifications in order to keep up with market demand and remain attractive to customers. This article is going to introduce some prominent Asian manufacturers and review their capacities. Sabek is an Arabian petrochemical company. It produces a wide range of chemicals, fertilizers, polymers, and plastic. They also operate mines and extract metals. Among the biggest petrochemical companies, this company comes fifth after companies like BASF, Synopack, Axon Mobil, and Chemical dove. Borouj company is a producer of raw materials. It is a progressive and innovative enterprise in the production of plastic materials. They work in conjunction with Abu Dhabi national oil company, one of the biggest oil companies in the world, and Borealis company in Austria. This company is innovative in offering chemical and plastic solutions. They are based in UAE and have offices in Singapore. More than 3000 people from 40 nationalities work in this company with customers from more than 50 companies from all over the world. Using exclusive Borlink and Brostar technology, added to 50 years of experience in working with polyolefin. Borouj company has offered solutions for reinforcing the infrastructures of pipe (pe pipe) systems, cable insulation covers, and pragmatic packing plans. Also helping to solve global environmental issues such as global warming, world food strategies, drinking water supply, energy-saving strategies, medicine, and hygiene, also waste management are among the fields in that Borouj is involved.
HDPE Pipe Manufacturers
Pipe manufacturers need to put up their PE and Hdpe product variety in order to survive in the current competitive market. Iranian PE and PVC pipe manufacturers have for long incorporated market experience and top quality raw material into their productions procedure they have also been diligently innovative by allocating constant resources to research and development. 
With regards to procurement of raw materials, Iranian petrochemical companies have for long been actively involved in producing high-quality raw materials to feed PE pipe manufacturing and other polymer or plastic raw material. A number of such companies will be introduced here. Shazand petrochemical company produces different raw and processed petrochemical materials including polyethylene, polybutadiene acid acetic, vinyl stat, ethylene oxide, ethylene glycol, bi ethyl hexane, butanol, butachlor/alachlor, and ethanol amines. Ethylene propylene butylene and betadine are important derivatives of natural oil and gas which constitute the building blocks of hundreds of chemicals, like high polymers, and plastic, to name but a few. Ethylene is the foundation component of chemical substances such as ethylic alcohol, ethanol amine, ethylene glycol, polyethylene, and thermoplastic material. Polyethylene has a variety of applications. It comes in sheet form when used for packing, it comes in filament form when used in the production of rope and it comes in melted form when used in making plastic bottles and the like. Petrochemical substances are used in the composition of anti-freeze, aspirin, synthetic fibers and medicine, synthetic rubber, detergents, soot, and the like. Among the most important of these substances are azote fertilizers which are widely used in agriculture. Altogether at the moment, there are 3500 petrochemical products. Other prominent companies producing raw materials include. Jam petrochemical company, Maroon, Tabriz, Arak, Mehr, Kermanshah, Ilam, Bandar Emam, and Abadan.
PE Pipe Fittings
To make sure we have secure connections for poly ethylene pipe we must choose fittings that are strong and durable. Polyethylene fittings are undeniable an integral part of the agriculture industry. If you want to start an irrigation system you will definitely need polyethylene fittings. These fittings are designed in various types and sizes. So that for each application there is a suitable fitting. On the other hand, the material used in making them i.e. polyethylene comes with advantages none of which can be found in other materials. 
These advantages make polyethylene fittings particularly popular. Some of those advantages will be briefly reviewed here:
- Polyethylene fittings are easy and quick to install. Each part of the fitting is made up of 3 parts which are responsible for a tight attachment and preventing leakage.
- Strength and high resistance. Compared to other materials in the market poly ethylene is the strongest assuring the user that there will not be any fracture or cracking under pressure.
- Unlike fittings of other materials, which rust after some time and need to be replaced, Polyethylene will not rust or corrode. It can last for a long time in a humid environment without taking effects whatsoever.
- Resistance against chemical substances is another feature of these fittings which makes them attractive to farmers and gardeners. if you are a farmer and need to use your irrigation system as a system for pesticide nebulizer you are highly recommended to use polyethylene fittings because they will never be corroded by chemical pesticides.
PE Pipe Sizes
PE pipe comes in a wide variety of sizes to accommodate the many different applications they are used for. One such application that has not been talked much about is the use of PE pipes for transferring gas, for this purpose also this type of pipe is manufactured in different sizes. For transferring gas and other gaseous fluids 25 mm PE pipe is a good popular choice. This is the thinnest PE pipe allowing a low volume of gas to pass through with a quick look at the main gas pipelines we can see how important 25 mm gas PE pipes are in this industry. 
Transmission of gas is usually reviewed in two main cases, first is the transmission of urban gas that is produced in the refinery and the second is the transmission of other gasses that takes place in the process of refining raw oil from origin to destination. the important and common point in both of the distribution networks is the pressure of the pipeline, this pressure is too high at the origin. Using a 25 mm gas PE pipe at this stage is definitely not recommended because the diameter is too little and it is not designed for such pressure. The solution is of course simple. For such cases, thicker pipes are used which can stand higher pressure until they reach cities whereas, at gas pressure regulation stations, thicker pipes are divided into smaller subbranches. Until it reaches the consumer in 25mm PE pipes.
