A complete buying guide for pp fittings

A complete buying guide for pp fittings In this series, all the advantages and disadvantages of plastic pipes are discussed and the reader is introduced to the most common types of plastic pipes used in the installation industry and their applications.

The use of plastic pipes in installations dates back to the mid-1930s. For the first time, the Germans used plastic pipes for drainage systems. Subsequently, the recognition of more and more disadvantages and disadvantages of metal pipes led to the replacement of plastic pipes over time and in many cases.

The most important disadvantages of metal pipes are corrosion, internal surface deposition, high weight, transportation and installation problems (compared to plastic pipes).

Although plastic pipes have their own disadvantages and disadvantages, however, certain types of them are the most suitable for particular applications, and in the light of increasing progress. In the petrochemical and polymer engineering science and technology, methods have been devised to improve the quality and resilience of plastic tubes and their defects, which have been very effective and are now extensively researched as well Production of new plastics and polymers, especially composite polymers for industrial pipe production, is underway.

Plastics are man-made materials based on organic polymers and are highly versatile. Basically, plastics are divided into two general categories based on their heat treatment behavior:

1- Thermoplastics.

2- Thermosets.

PP Pipe Fittings Manufacturers in Asia

Asia polypropylene pipe is one of the high quality brands that has gained national and international certification. In general, polypropylene pipes are made of materials that give these pipes the chemical and physical structure of stability and are therefore considered.

Polypropylene pipes are electric current and heat insulators and normally have a temperature resistance of up to 90 ° C.

In addition to being resistant to rust, these pipes do not alter the structure of the pipes and are highly resistant to corrosion by salt, acid, base, organic solvents.

Light weight and ease of transportation with a solid structure are significant advantages of the Asian polypropylene tube.

Polypropylene pipes are environmentally friendly pipes and are considered for their recyclability.

High abrasion resistance, high flexibility and therefore brittle resistance are other advantages of these tubes.

The aforementioned advantages for Asian polypropylene pipes make them widely used and consequently are used for such things as chemical discharge industry, hot and cold water transfer, drinking water piping, sewage systems, chemical drainage.

Asian polypropylene pipe fittings are widespread and come in a variety of knees, convertible knees, vertical knees, 45 degree knees, tees, transformers, fasteners and bushings. These pipes and fittings are also available in high pressure types.

Polypropylene pipes and fittings are also known as green pipes. These pipes are made of polypropylene polymer. Thermal welding machine is used to connect polypropylene pipes and fittings. This device is known as an ironing pipe.

Manufacturers have been trying to add new properties to these pipes so that customers can buy them with greater confidence, so the R&D department continued to add useful additives to these polymers to counteract their negative effects.

Who are the biggest plastic pipes and fittings producers?

Who are the biggest plastic pipes and fittings producers?  In particular, the role of plastic pipes in the transmission of water and natural gas and the development of these industries are very colorful. Due to the high demand for plastic tubes, various types of these tubes have been rapidly developed in various dimensions, and today, much scientific information is needed to select the right plastic tube for each user. The most common types of plastic pipes are polyethylene and polyvinyl chloride pipes.

Types of plastic pipes

The plastics used in pipe manufacturing are a combination of base polymer and additives. Additives are added to create special properties such as protecting the polymer during the manufacturing process and subsequently, improving some properties, creating color, and so on. Types of heat stabilizers, antioxidants, optical stabilizers, softeners and lubricants, fillers, etc. are additives.

Choosing the right material for making the pipes will depend on the fluid being transported and the service and operating conditions of the system. Depending on the type of plastics, some of the properties of plastics may be desirable for our desired system and facility, and some may be undesirable.

Although some of the undesirable properties can be reduced or eliminated through standard design and installation, however, choosing the right pipe for different applications requires sufficient knowledge of the properties, advantages and disadvantages of plastic pipe types. Is. Below we will discuss the most important features and characteristics of plastic pipes.

Abrasion and corrosion resistance

In general, plastic pipes are highly resistant to acids, salts, liquids and corrosive gases. In the case of erosion, the degree of resistance of the plastic pipe depends on the type of fluid being transported through the pipe and the conditions of service and system.

The degree of corrosion resistance of plastic pipes varies with the concentration of certain chemicals. For example, polyethylene pipes can transfer 70% sulfuric acid at 23 ° C (73 ° F), while not suitable for 95% sulfuric acid transfer.

Temperature is also an important determinant of corrosion resistance of plastic pipes. For example, some polyethylene pipes that are suitable for the transport of nitrogen oxides at 23 ° C should not be used to transport these gases at 50 ° C.

The specific formulation of a particular plastic material can also be used to determine the amount of material’s overall resistance to corrosive chemicals and their concentration.

Internal wall filter

Plastic tubes have ultra-smooth inner walls, preventing the accumulation of any type of sediment on their inner walls, thus causing the problem of clogging and obstruction due to the gradual decrease in inner diameter due to Sediment accumulation is eliminated in the case of plastic pipes. As the metal pipes have lost corrosion over time and the accumulation of sediments on their inner surfaces has increased the frictional pressure drop thereby reducing their capacity for fluid transfer.

Biggest buyers and importers of pp fittings? In general, plastics are not conductors of electricity, and therefore types of plastic pipes are never exposed to galvanic and electrochemical corrosion. As you know, the occurrence of galvanic corrosion phenomenon in buried metal pipes under the soil is one of the most important causes of their damage and gradual disappearance.

Density

Plastic pipes are much lighter than steel, asbestos, concrete and cement pipes and are in density ranging from 0.9 to 3cm / gr2 (depending on the type and formulation). The lightness of plastic pipes has many advantages for this type of pipe. Including the fact that their transportation and installation costs are much lower and their transportation is easier and faster than other pipes. Most plastic pipes are easy to install by hand and in most cases require no special machinery or tools.

mechanical properties

Of course, plastics do not have the mechanical strength of metals, but the mechanical properties of plastic tubes are more flexible. Plastic resistance against tensile forces is excessive. As the temperature of the piping system increases, the mechanical strength of the plastic pipes decreases, but the impact resistance increases. Since plastic tubes are generally tough (yet robust) they absorb external blows to their surface with minimal damage or even no damage. However, the same impacts on brittle pipes can cause serious injury.

Flammability

Plastic tubes are mainly made of polymers and carry other organic compounds and are therefore flammable. Of course, different plastics exhibit quite different behaviors against fire. In most cases, fire causes chemical decomposition in the structure of plastic pipes, and the products of combustion of these pipes increase the volume of fire. .

What are the disadvantages of pp fittings?

The general properties and engineering of plastic pipes can be controlled by standards, and in many applications there can be several choices due to the overlap of properties between different plastics. Therefore, it is necessary to fully understand the position of the user and to master the different properties of the various types of plastic pipes. The advantages and disadvantages of polyethylene pipes

In general, the following benefits to the general public of plastic pipes are:

  • – Corrosion resistance: Plastic pipes do not corrode most of the chemicals present in domestic wastewater and also have minimal resistance to the passage and transfer of sewage and other fluids due to the smooth surface. These pipes will never rust and will not corrode.
  • – Lightness and ease of transportation: In addition to ease of transportation and cost reduction, in the case of plastic pipes cutting, joining and installation is much easier than other types of pipes such as metal pipes.
  • – Flexibility and toughness: Particularly in underground applications, the flexibility of plastic pipes reduces the number of connections and easily curves the plumbing paths.
  • – Various methods of connection: In general, plastic pipes have the ability to thread, flange, heat weld, glue, compressive joints, etc. and provide a wide variety of connections for different conditions.
  • – Excellent hydraulic properties: Plastic pipes fall into the group of flat surface pipes, which results in the least energy required to transport various fluids.

Longevity and low cost over life: Plastic pipes have been used in most cases for more than 25 years and have not yet reached the end of their service life, on the other hand due to lower purchase, installation and maintenance costs. Other common pipes require little cost during use.

Are pp fittings more expensive than pvc fittings?

Are pp fittings more expensive than pvc fittings? Comparison of PVC and PP Pipes in Polymer, Construction Sewer Sections

Today, most PVC and PP joints are used in the construction sector. As these pipes became popular and replaced with copper and cast iron pipes, the focus on quality and mass production of PVC and PP pipes increased.

Manufacturers have been trying to add new properties to these pipes so that customers can buy them with greater confidence, so the R&D department continued to add useful additives to these polymers to counteract their negative effects. Increase their health and safety so that today we are in the field of manufacturing PVC and PP tubes with the best kits.

PVC and PP pipes are both used in the construction and municipal wastewater sector. So it is better to have a general comparison of these two types of pipes and their properties.

Fire Retardant Properties:

When a material is ignited, the risk is directly related to its flammability. One of the most reliable small-scale flammability tests is the Oxygen Limit Test, which is the measurement of the oxygen concentration in a mixture of oxygen and nitrogen that is required to continue combustion.

A material with a LOI greater than 2 should not burn in air at room temperature, and a high value of 1 to 2 means that it will only burn under very high heat. Hard PVC has an oxygen index of between 1 and 2, which is significantly higher than wood with a LOI of 1 to 2 and many thermoplastic LOIs of 17 to 5.

The ignition temperature of the PVC is above 0 ° C, and because it is not easily ignited, it is a significantly lower risk material for fire incidents, plus the heat released during burning is significantly lower for the PVC.

Chemical Resistance:

 PVC is resistant to many alcohols, fats, oils and gasoline. It is also resistant to most corrosive minerals, including mineral acids, alkalis and salts. However, PVC should not be used with aromatic and chlorinated esters, ketones, ethers and hydrocarbons. PVC absorbs these materials and this results in a reduction in tensile strength.

Mechanical Stability:

 PVC is a stable chemical that exhibits little variation in molecular structure as well as mechanical strength. However, long polymer chains are visco-elastic materials that can be deformed by external force, called creep deformation, although PVC is a viscoelastic material but its creep deformation is comparable to that of polyethylene. And polypropylene is very low so PVC pipes have a longer life span than the two.
