Polyethylene pipe is a simple pipe made of polyethylene, which is similar to the polyethylene material that gives the tube a good effect, which has the advantages and benefits of the popularity of polyethylene pipes.
Polyethylene pipes have many advantages, including high quality, reliable polyethylene pipe and fittings, ease of loading and transportation of polyethylene pipes and fittings due to their relatively low weight, quick and easy installation, different types of polyethylene It is also the best choice in a variety of projects. Also, the polyethylene pipe has a suitable bending radius and has a very good resistance to impact and pressure at very low temperatures. Acid and gamma-like environments as well as many solutions and materials The chemical does not affect the polyethylene. The same is one of the most important advantages of the polyethylene pipe and fittings Polyethylene.
Polyethylene materials used to produce polyethylene pipes are different from the type of polyethylene materials used for the production of other polyethylene products. Polyethylene is available in various grades, and each of these materials Polyethylene is used for a variety of applications. Polyethylene is a variety of thermoplastic polymers, which means that this material converts to solid state when it reaches its melting point and reaches the solidification point. Polyethylene chemical synthesis Ethylene is usually a mixture of crude oil and natural gas
Polyethylene is available in various grades, and each of these polyethylene materials is used for various applications.
Types of grades of polyethylene
These materials are currently out of stock and are not used. These materials are slightly more dense than newer materials and therefore have a higher weight and thickness, which cost much more than newer materials that are practically It does not have economic justification.
The use of newer materials, called the PE 80, was produced after the raw material manufacturers found that by increasing the density of materials, they could be achieved in the thickness and weight of materials with higher pressure and lower costs.
The PE 100 material is one of the newest types of raw material, which, in terms of physical and functional characteristics, has unique properties that can withstand higher pressures with higher density and lower weight and thickness.
Polyethylene PE 100 has virtually eliminated the problem of polyethylene tubes due to ultraviolet ultraviolet radiation. PE 100 polyethylene grades have a much lower weight and higher strength than other polyethylene grades. The reason is economically more economical, and the polyethylene tube produced with these materials is less than the same as the same tube with lower grade materials.
Polyethylene raw materials for the production of polyethylene pipes
Polyethylene raw materials are produced and supplied to the market by the petrochemical industry to produce polyethylene tubes in both white and non-black materials (black). Each of these materials is for production purposes, but for polyethylene pipes Ethylene, which is used for sensitive and high pressure applications, is more suitable for black materials. If they are blended with modern and professional machines with masterbatches, they will be of good quality, which is perfectly for the line equipment Production depends on the device called gravimetric device, which is installed before the extruder hopper.
Masterbatch or Compand contains a polymer base and chemicals. The polymer base is selected depending on the final product and properties, and the chemicals also depend on the optimal properties required, so that if the paint is to be used, the chemical Use inorganic or organic color, or, if strength is considered, they use reinforcers and also use appropriate chemicals depending on the requirements of process properties or products.
Strong pressure polyethylene pipe
High-pressure polyethylene pipes are used to transfer fluids permissible under pressure. Types of single-wall polyethylene pipes determine the type of raw material and its application. For example, for agricultural applications and drip irrigation and irrigation under pressure in gardens. They use pipes of low diameter or irrigation bristle bars.
Polyethylene Pipe Standards
The standard for polyethylene pipes is based on DIN8074 and its national standard ISIRI 1331 and ISIRI 14421 for PE100 polyethylene pipes with a 25.1% safety coefficient and a temperature of 20 ° C with a life span of 50 years and permissible pressure.
Polyethylene tubes produced by Rothengaran are made of PE100 material with suitable bending radius. This property makes it easy to install polyethylene pipes and, as a result, requires the use of fittings in a smaller project. Nowadays, PP pipes are used in water, oil, gas, oil and petrochemical projects.
