What are the advantages of pp pipe fittings
One of the unique features of polypropylene pipes is the smooth and smooth surface inside and outside the pipe. This feature makes it easy to move fluids inside. Most of these pipes are sound and heat insulated. Therefore, the movement of fluids, including water inside these pipes, will not be accompanied by sound. Also, the proximity of hot water pipes along with other appliances will not harm other appliances.
In metal pipes, rust is just one of the problems that change the taste of drinking water inside the pipe. In addition to the rusting of the material inside the metal pipes, it creates many problems and, on the other hand, allows the growth of algae and fungi. The good feature of the polypropylene pipes is that they are anti-algae and the color and taste of the water inside them will not change, so it is used more in the construction pipelines.
And finally, the characteristic of these pipes is their relatively long service life. Polypropylene pipes with a life span of more than 5 years can reduce operating costs in construction piping and urban and industrial installations. Polypropylene pipes are easy to transport and move. The light weight and pressure resistance of these pipes make polypropylene pipes in the ground and last for many years.
Polypropylene pipes are available in two colors, green and white, and each of these pipes can be used in auxiliary and building plumbing fittings.
What separates polypropylene from other plastics is the flexibility at specific temperatures. The melting point of this material is also very high and is not easily damaged by vibrations and stresses. Because opening and closing pipes are important for operating applications, polypropylene pipes are used more frequently than other materials because they can be easily opened and closed multiple times without damaging or eroding them.
It should be noted that materials can be added to polypropylene pipes to make their properties distinct and high-color. For example, polypropylene pipes add minerals for added flexibility. These materials allow the polypropylene tube to be made into a synthetic sheet and easily cut. Convenience in cutting polypropylene will have a good effect on the production of pipes of different sizes.
The only disadvantage of polypropylene pipes is that they are not resistant to sunlight and can easily break. This feature allows polypropylene pipes to be used only in small surface applications along with other plastics. Due to the low price of the types of polypropylene pipes, these pipes have replaced the metal and cast iron pipes on the market.
Are pp pipe fittings durable than pvc pipe fittings?
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 1. Because it is not easily ignited, a lower risk material for fire incidents plus the heat released during burning is significantly less for PVC.
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 reduced tensile strength.
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.
Weather Resistance (Climate Factors):
PVC pipe materials have sufficient UV shielding, usually titanium dioxide, and can be stored outdoors for up to a year. Special care must be taken to ensure that PVC pipes formulated for outdoor use are guaranteed to be a weatherproof product otherwise the performance of the outdoor may not be satisfactory.
PVC materials can be combined with a good amount of titanium dioxide to produce a high-strength product that can be referred to as siding, window profiles, etc. These PVC compounds are formulated with a UV-resistant PVC resin and other air-resistant additives and materials.
Which is more expensive? PP fitting or PVC?
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 began to work on and consistently added 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 pipes 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.
Due to the large number of fasteners used to restrain polypropylene pipes and the fact that at least two fasteners are used per meter, plus the cost of polypropylene pipe material being lower than PVC, the cost of system implementation Elevates. PVC is glued together so it is relatively easy and inexpensive to install.
Due to the low flexibility of the polypropylene joints, the ability to withstand structural movements caused by a seismic or earthquake is very low. PVC pipes with high elastic modulus can withstand a variety of static and dynamic loads.
The advantages of the high elastic modulus are to neutralize damage caused by motion or vibration, such as earthquakes. In addition, in the building to prevent breakage of the grid at horizontal junctions during vertical building assembly or earthquake, the proposed Tuberculosis Installation method is recommended. Adhesive and Push Fit Installation The correct method of vertical installation using the 2% backfill and 2% Push Fit with clamps used to install them costs more than the adhesive method. All horizontal and buried parts of building materials can be glued only to vertical risers on each floor of a cup. G’s expansion.
Various Types of Polypropylene Pipe Fittings
Recycling polypropylene materials, like many other soft heat materials, created a wave of happiness for environmentalists. Although polypropylene pipes are synthesized in industry and in the laboratory, their recycling can hide many of their environmental problems. In fact, there is no concern about the volume of chemicals produced in these materials, and polypropylene materials can be recycled and reused over and over again.
Properties of polypropylene pipes
- High chemical resistance
- Good wear resistance
- Heat resistance
Production of polypropylene
Polypropylene is produced by a solution or gas process and its monomer is exposed to heat and pressure in the presence of a catalyst. Differences in catalyst and production conditions can alter the plastic properties.
Polypropylene monomer is propylene. Polypropylene is a linear hydrocarbon polymer expressed as CnH2n. Polypropylene is one of the multifunctional polymers in the plastics industry due to its multiple applications.
The presence of methyl group in the structure of polypropylene has caused the properties of this product to be changed to polyethylene. This structure increases the melting point of the crystal, which is why polypropylene is more resistant to heat. Polypropylene is divided into three types of isotactic, syndotactic and atactic, which have different structures.
Application of polypropylene pipe
- Chemical discharge systems
- Industrial Processes
- transferring water
- Hot and cold water distribution
- Wastewater Systems
- Plumbing Side Fittings
What is the difference between PP and PVC?
Polypropylene is one of the most widely used plastics and is widely used in many industries today. Although PP is slightly more expensive than polyethylene (PE) for a given weight, polypropylene
Polymeric polypropylene with an approximate density of 0.9 g / cm3 is obtained from the polymerization of the propylene monomer. It is resistant to moisture, oils and ordinary solvents and melts at about 170 ° C. This non-toxic, odorless substance is burnt into wax-like droplets as it burns like a candle and burns with a little nasty flames. The combination of properties such as lightness, hardness, toughness, chemical resistance and surface finish have resulted in a variety of products made from this material. One of the important properties of PP is its high stability against bending at low thickness, Polymeric nge plastic springs which enables the production of very diverse components.
Polypropylene is used in a variety of fields, for example in the automotive industry, in the manufacture of door panels, interior decorations, propellers, car flooring, battery boxes, and so on. Most drinking straws are made from PP. Most sachets and toys are also made of this polymer. Approximately 10% of PP production is used in film making, which is used in food packaging. About 30% of the PP produced is used in the manufacture of single strands and fibers. PP fibers are used in making carpet, carpet, rope, sack, etc.
Although polypropylene as a homopolymer is widely used, propylene copolymer with ethylene is also a growing market. By increasing ethylene during polymerization, polymer with lower modulus and higher impact strength is obtained. The higher the ethylene, the more pronounced the effects. These copolymers are available both as a random copolymer and as a block copolymer.
PVC pipe, or polyka pipe, is one of the earliest polymer tubes to be used in the construction industry and is often used for water and wastewater piping because of its cheapness and flexibility.
Polyvinyl chloride (PVC), or PVC, is a plastic with unlimited use. At present, it is one of the most valuable products of the petrochemical industry. More than 5% of human-made PVC is generally used in construction because PVC is both inexpensive and easy to assemble.
There has been a great deal of research and development in recent years in the manufacture of PVC pipes, both in the production of raw materials and in the production of PVC pipes. The use of suitable formulations for the production of U-PVC pipes enables the use of these pipes for drinking water transmission in accordance with NSF 61-62 standards and ensures that lead, tin and other toxic elements such as mercury, worms are used. , Cadmium and Barium are below the standard permissible limit.
U-PVC pipes have a very good price and are able to compete with other polymer, metal, cast iron pipes, so today U-PVC pipes are one of the main options in the world. They are water and sewage networks.
