How to identify PE pipes from PP pipes?

Polyethylene is a group of polymers that are obtained by the polymerization of ethylene gas (C2H4) with different physical properties such as density, crystallinity, branching grade and lattice, etc. The polymer can be determined by the type of polymerization and the type of catalyst Kurdish. Polyethylene is the simplest commercially available polymer, a chain of carbons that is attached to a two-hydrogen carbon atom. Polyethylene has different grades that are classified according to density, polymer chain size, type and number of branches in the chain. Since 1955, the use of Ziegler-Nata catalysts has made it possible to produce low-pressure polyethylene of various types.

In contrast, one of the most widely used polymers is world polypropylene (PP). Polypropylene is made from the polymerization of propylene at the appropriate temperature and pressure in the presence of the Ziegler-Nata catalyst. It is resistant to moisture, ordinary oils and solvents, and is non-toxic and odorless. It has lightness, hardness, toughness, chemical resistance and high surface finish and is very resistant to bending. The most important feature of this material is the lack of moisture absorption which has been used in many applications.

Here are some tips for choosing the right polymer:

  • Polyethylene is softer than polypropylene and elastic and flexible, so polypropylene is more commonly used to produce molded parts.
  •  The density of polypropylene is lower than that of polyethylene and its melting point is higher. PP is used in fiber production.
  • PE is more resistant to cold as determined by the analysis of this case. It is also more resistant to PE light than PP, so it is used more in traffic signs.
  •  Polypropylene is more transparent than polyethylene, which is used in industries where more transparent material is needed as PP.
  • The chemical resistance of PP to organic solvents and acids is greater than that of PE.
  •  PE has better electrical insulation than PP because its static charge is less than PP.
  •  According to studies, PE is more recyclable than PP.
  • High purity PP polymerization is easier than PE.
  • In the pipe and fittings industry, PP pipes are more resistant to high pressure fluid and have a wider temperature tolerance, which is why they use the same type of pipes in the hot and cold water system, for indoors more than pipes. PP and PE type are more suitable for exterior applications of water and wastewater systems.
  • In the packaging industry, PE and PP polymer films are used, which are more flexible and more resistant to PE. In contrast, the PP type has clearer crystals that are suitable for food packaging and preserve flavor.
  • PP is stiffer than PE and has higher chemical and thermal resistance while impact resistance is higher in PE flooring and higher toughness. They are also more economically advantageous.
  • Polyethylene adhesion is lower than polypropylene.

The best material can be selected according to what is said.

Durable and safe pipes for hot waters

With the advent of polymer materials, plastic pipes such as polyethylene pipes, pipe fittings and PVC pipes have been introduced to the market and have gained immense popularity in a short time, so engineers prefer the pipe. Polyethylene pipes for installation in water and sewage transmission networks.

Polyethylene pipe and uv PVC pipe are manufactured in different sizes and each of them is selected according to the project of plumbing and installations. These pipes are of different diameter and thickness and are designed to operate at different operating pressures. Currently, plastic pipes are one of the most common water and sewage conveyor pipes. Double walled polyethylene pipes, including carogite pipe and spiral pipe, are used for large water and wastewater projects. Sanitary sewer transmission by plastic pipes is possible.

Review of pe and pp pipes market in 2019

Polyethylene and polypropylene are the most widely used polymers and are in the group of thermoplastic and semi-crystalline polyolefins, which are widely used in various industries.

What is the difference between polyethylene and polypropylene?

In many industries, both can be used, but you may be wondering what the difference is between these two polymers, here are some pointers that knowing which one is the best choice for the industry. The main difference between the two polymers comes from their monomeric unit. The monomeric units of polyethylene and polypropylene are ethylene and propylene, respectively.

Plastic pipe types are the most widely used sewage pipes, the most important of which are PVC plastic pipes, PE plastic pipes, ABS plastic pipes, PP plastic pipes and CPVC plastic pipes. In this post we are going to introduce you to PE plastic tubes. Stay with us.

PE pipes

Another pipe used in sewage piping is thicker and more dense than PVC pipes. These black pipes are highly polycrystalline and therefore used for piping in the urban water distribution network. Polyethylene pipes are bonded together by the method of heat welding and head to head welding. The most important advantages of polyethylene pipes can be high resistance to corrosion, rot, wear and impact as well as low weight, high flexibility and shrinkage, sufficient earthquake resistance, very tight and leak-free connections, adequate radiation resistance.

Best wholesale places to buy pe fittings cheap

Ask the vendor for mandatory standard certification before purchasing polyethylene pipe and match the information with the information on the pipe. Having the standard mark is a prerequisite for purchasing polyethylene pipes and is the first step to trusting reputable manufacturers. The lab and the quality control manager examine the quality in three stages: first in the polyethylene raw material phase that enters the factory, then in production and finally in the pipe as the final product.

  • Check the appearance and marking of the pipe
  • Melt flow index measurement
  • Measuring mass percent
  • Density measurement
  • Measurement of OIT Oxidation Induction Time
  • Brest test and how the PE pipe bursts
  • Measurement of dimensions, diameter and thickness of the produced pipe
  • Determination of soot distribution and distribution
  • Thermal return measurement
  • Effect of pipe on water
  • Determine the density of raw materials
  • tensile test

Is it OK to buy used pe pipes and fittings?

Second-hand polyethylene pipes are often the ones left at the project site. Second-hand polyethylene pipes are, as the name implies, a surplus pipe and the reason why the pipe is sold as a second-hand pipe is important. Here are some of the reasons that secondhand tubes are being marketed:

  •   The polyethylene pipe at the project site is over-sized and over-needed
  •  The PE pipe is damaged at the project site and is not suitable for use
  •    The polyethylene pipes provided as second-hand pipes are of poor quality and do not meet the project requirements.
  •  Polyethylene pipes are not standard and they want to sell somehow
  •  The raw materials used to produce that pipe were not suitable

Second-hand polyethylene foam is a waste in general and is not suitable for use because of its raw materials, manufacturing plant and storage methods. It has no reliable and documented track record. It is important that these pipes may have been exposed to direct sunlight for many years or that they were stored at very low temperatures and outdoors. The crucial point is that by no means and experiments can the health and quality of the second-hand polyethylene pipe be assessed properly and the type of material can be identified in the experiments, but the manufacturing process, the method and how it is manufactured, as well as the production documentation in the area of ​​ambiguity remain.

Second-hand polyethylene pipe is also not a good waste to return to the production cycle of the PE and should be used to produce other products that do not have a strategic and sensitive function such as a basket. We also need to talk about the waste polyethylene pipe, the appropriate waste polyethylene pipe is the waste that occurs in the factory and covers all aspects of waste during production. These wastes are well-documented and can be tracked as raw materials and how they become waste, so they are sent to special locations for reuse for production of some PE and recycled pipes and are reused at great cost. They become granules.

Purchasing second-hand polyethylene pipes for pipelines is not appropriate at all, and is not even recommended for wastewater and non-pressurized streams, as these lines are very important to be worn and the second-hand couplings are difficult to carogite and Or their gaskets may have been damaged due to inadequate storage conditions. Purchasing second-hand polyethylene pipes from its dealer and reusing them is just a mistake, but some pipes manufacturers and advertisers have ads to buy second-hand polyethylene pipes! For what purpose do these manufacturers use these pipes to recycle the unnamed pipes and return them to the production cycle of the polyethylene pipes?

Brass pe pipe fittings at affordable price

One of the most widely used types of fittings in the industry is the brass fittings, which are manufactured and sold because of their wide use and great advantages in large quantities. These joints are classified into different types according to the type of application, the type of structure and the size. These types of applications are classified into types of brass, water, gas, and compressed air fittings. The type of fluid flowing in the lines connected to these connections, the type and thickness of the transmission lines and pipes are the determinants of the type of connection based on the structure. For example, brass fittings are available in two general types, high pressure and high pressure, which can be used if the pressure in the transmission lines is high pressure. High pressure brass fittings are widely used in the oil and gas industry. Based on their structure, these joints refer to the types of brass knee, brass bushing, brass conversion, three-way brass, brass quadrilateral, brass hinge and brass, nipple and brass gear, left-hand and brass hinge.

The feature of the bras used in these connections

brass is one of the most widely used alloys due to its specific physical properties. The melting temperature of brass is very high, and the metal, which is a combination of copper, zinc and other minor elements, has high mechanical and thermal resistance. It is worn later than other metals and is resistant to corrosion. Also, this type of metal is not stained and opaque and is very suitable for building fittings. The metal’s cold and hot forming ability is excellent and is therefore used in the manufacture of fittings.

Polypropylene is a thermoplast that is obtained from the polymerization of propylene and is recyclable. Polypropylene was first manufactured on a laboratory scale in the early 1950s and later commercialized later this decade. Polypropylene was initially estimated to be less costly to produce than polyethylene PE. Polypropylene is produced in three isotactic, syndiotacti, and atactic forms, which are mainly in the isotactic form by adding a small amount of other monomers (mostly PE).

Attributes

Tensile strength, low density, colorlessness, hardness, acid, base and solvent resistance are some of the properties of PP pipes. Its low production cost compared to other thermoplastics has created a special place for polypropylene PP in the industry.

Indications

PP pipe is mainly produced in the following six categories

  •  Injection Molding (Injection Molding)
  •  Fibers
  •  Sheet / Film
  • Blow Molding
  •  Pipe
  • Extrution Coating

Plastic Piping & Pipe Fittings With Huge Variety

The price of polyethylene pipe varies with the purity of the raw materials used. The main raw materials for PE pipes are pe40, pe63, pe80 and pe100 which determine the price of PE pipe. The price of polyethylene pipe and its purity is the amount of raw material and waste material required. Raw materials for making PE are waste produced from grinding of used PE pipes. Most polyethylene pipes made from scrap materials such as granules or compounds have specific properties and applications in the industry. The price of polyethylene pipes on the market is not very different, as it is obvious to most manufacturers. So if you see a price somewhere that is significantly different from other prices, keep in mind that these pipes may be manufactured from scrap materials.

Specifications of PVC pipes

PVC pipe (UPVC pipe) is one of the first and most widely used polymer pipes and PVC pipes of different types were produced and marketed. PVC pipes are badly damaged and have a long life span, and due to their high resistance to environmental conditions, they quickly gained popularity and were able to transport wastewater, water supply and fluids in many projects.
