What are the differences between ABS pipes and PE pipes in terms of use?

PE is a soft plastic.

ABS is a rigid plastic.

ABS has valves, and in the case of PE, the valves need to be added with other additives. Otherwise, it is easy to leak.

The temperature of ABS is 70 degrees and that of PE is 40 degrees.

ABS glue is connected, PE is hot melt.

The labor cost of ABS is low, and the labor cost of PE is high.

ABS has high impact resistance and can be added to a variety of resins, such as UPVC, etc., but it is not flame retardant. PE is divided into high density, low density, medium density, etc., and the temperature resistance is 40-minus 40 degrees.

The differences between ABS pipes and PVC pipes are as follows:

1. Differences in meaning.

ABS plastic hall chop and pipe is a new type of material, the material is ABS acrylonitrile butadiene styrene.

PVC pipe (PVC-U pipe) rigid PVC pipe is extruded by hot pressing method after combining PVC resin with stabilizer and lubricant, and is the earliest plastic pipe to be developed and applied.

2. Differences in characteristics.

ABS plastic pipe has low flow friction, greatly reduces fluid resistance and pump horsepower, has good impact resistance, good mechanical strength and high pressure; Impact toughness, in which only ductile deformation occurs when subjected to a sudden attack.

PVC pipes are easy to bond, low-quality, hard-textured, have good tensile and compressive strength, good watertightness, excellent corrosion resistance and chemical resistance.

3. Differences in application.

ABS plastic pipes can be used in pharmaceutical and food industries, without changing the water quality and without forming secondary pollution. ABS plastic pipes can generally be used indoors for decades, and will last longer if buried in the ground or water.

PVC pipes are suitable for water supply systems with conveying temperatures not exceeding 45. For applications in drainage, wastewater, chemicals, heating and coolants, food, ultra-pure liquids, slurries, gases, compressed air and vacuum systems.

PVC material composition and characteristics:

PVC is a kind of plastic product synthesized from 43% oil and 57% salt, its chemical name is called polyvinyl chloride, it is mainly made of vinyl chloride monomer through polymerization reaction, this is not shaped thermoplastic resin and then certain additives such as stabilizers, lubricants and fillers.

PVC material has mechanical properties, its acid and alkali resistance is very strong, the softening point is also very low, the chemical properties are very stable, and it is generally used to make thin plates, wires, cables insulation and seals and other items. Compared with other types of plastic products, PVC uses raw meal more efficiently and reduces fuel consumption.

At the same time, the energy consumption of PVC manufacturing will also be low. And in the later stage of the use of PVC products, it can be converted into other new products or incinerated to obtain energy <>

1. The application field is not the same as jujube.

ABS pipes are mainly used in domestic water supply pipes.

PVC pipes are mainly used to cover the protective pipes of wires and cables, or sewage pipes.

2. **Different.

ABS pipes are higher than PVC pipes**.

PVC pipes are lower than ABS pipes**.

3. Toughness is different.

ABS pipe is tougher than Hehao PVC pipe.

PVC pipes are less tough than ABS pipes.

1. Different materials: the main difference between PE water pipe and PPR water pipe is the material, the material of PE pipe is polyethylene, the material is medium density polyethylene, the elastic modulus is only about 550MPa, the flexibility is good, but the stiffness is insufficient, and the material of PPR pipe is random copolymer polypropylene, the elastic modulus of PPR water pipe is 850MPa, the stiffness is good, but the flexibility is insufficient. Plastic PVC is a polyvinyl chloride resin material.

2. Different uses: Another difference between PE pipes and PPR pipes is the use, PE water pipes are often used for municipal water supply and drainage pipelines, while PPR water pipes are often used for building water supply and home decoration water supply pipelines. PVC pipes are used for water supply and drainage, irrigation, gas supply, exhaust pipes, wire conduits, rainwater pipes, industrial anti-corrosion pipes, etc. for residential life, industrial mining, and agriculture.

3. Different installation: PE water pipe and PPR water pipe installation and welding are also different, PPR water pipe installation and welding temperature is 260, PE water pipe installation and welding temperature is 230. The installation and welding temperature of PVC pipe is 200 230.

PVC installation precautions.

1. When installing, the size should be measured according to the requirements of the drawings, the pipe should be broken, and the fracture should be ensured.

2. It cannot be fully inserted before the connection of PVC pipes, and the socket needs to be test-inserted. When bonding, if there is oil, dust, and even moisture inside, it must be removed.

3. Inspection openings should be set at the bottom and top of the drainage pipe, and the center of the inspection port should be one meter from the ground.

4. During the installation, the pipe should be placed gently to avoid damage caused by the installation process and ensure that the pipe can be kept complete and clean. After installation, a pressure test should also be carried out to confirm that there is no water leakage at each interface, otherwise it needs to be replaced and reinstalled immediately.

PVC pipe and PE pipe are common pipe materials, and they differ in many aspects, including material characteristics, scope of application, and use environment. Here are some of their key differences:

1.Material Convergence Characteristics: PVC pipes are made of polyvinyl chloride (PVC) material, while PE pipes are made of polyethylene (bent PE) materials. The chemical and physical properties of these two materials are different, resulting in differences in their pipe properties and properties.

2.Strength and hardness: PVC pipes are relatively hard and have high compressive and flexural strength, while PE pipes are relatively soft and have high toughness and impact resistance.

This makes PVC pipes suitable for applications that require high stiffness and pressure carrying capacity, while PE pipes are suitable for underground and above-ground piping systems, able to adapt to deformation and vibration of the ground.

3.Corrosion resistance: PVC pipes have good corrosion resistance to general chemicals and acidic and alkaline media, but some chemicals and solvents may cause corrosion to them.

PE pipe has good chemical stability and corrosion resistance, and has good corrosion resistance in many acidic and alkaline media and chemical environments.

4.Operating temperature range: The maximum use temperature of PVC pipes is usually between 60-70 degrees Celsius, while the maximum use temperature of PE pipes can reach 80-90 degrees Celsius. Therefore, in high temperature environment, PE pipe has better heat resistance than PVC pipe.

5.Installation and connection: PVC pipes and PE pipes are also different in installation and connection. PVC pipes are usually joined using adhesives, hot melt connections, or mechanical connections. The PE pipe is generally connected by hot melt connection or mechanical connection.

It should be noted that the specific performance and scope of application of PVC pipe and PE pipe may vary due to different specifications and manufacturers. When selecting piping materials, comprehensive consideration should be made based on specific application needs, engineering environment and relevant standards. If you need more accurate information and advice, it is recommended to consult a professional plumbing material supplier or engineer.

There are obvious differences between PVC pipes and PE pipes in terms of raw materials, performance, application fields, connection methods, ** and hygienic properties.

Raw material: PE pipe is made of polyethylene resin, which contains only two atoms, carbon and hydrogen. The PVC pipe is made of polyvinyl chloride resin and contains chlorine atoms in addition to carbon and hydrogen.

Performance: PE pipe has good flexibility and impact resistance, which is superior to PVC pipe. PVC pipes show the characteristics of strong rigidity and easy brittleness, and their expansion coefficient is low.

Applications: PE pipes can not only be used as water supply pipes, but also can transport gas. PVC pipes are mainly used in drainage pipes, because of their flame retardant insulation properties, they can also be used in the flame retardant threading industry.

Connection: PE pipes are mainly connected by hot melt or electric melting, and the connection will be integrated, and the interface strength is high. PVC pipes are generally connected by glue or sealing rings, and the strength and tightness of the joints are relatively low.

**: Under the condition of ensuring the same pressure demand, the wall thickness of the PE pipe needs to be made thicker, so it is relatively higher. Whereas, PVC pipes are comparatively thin and relatively cheap.

Hygienic performance: PE pipes have fewer raw material additives, so they are more in line with the requirements of drinking water pipes. PVC pipes may contain heavy metals such as lead and have relatively poor hygienic performance.

The composition is different: PVC materials are mostly PVC, which belongs to ordinary plastics; The composition of PC is mainly carbonate, which belongs to engineering plastics;

Different properties: PC material has the advantages of high strength, good transparency, good impact resistance, etc., relatively speaking, PVC material is softer, transparent and resistant, and the mechanical properties are not as good as PC material;

Different: PVC material is cheaper, and it's usually only half to a quarter of the PC material;

Different uses: with high transparency, light weight, impact resistance, sound insulation, heat insulation, flame retardant, anti-aging and other characteristics, is a high-tech, comprehensive performance of extremely excellent, energy-saving and environmentally friendly plastic plate, is currently the international commonly used plastic building materials, has other building decoration materials (such as glass, plexiglass, etc.) can not be compared.

Different characteristics: the light transmittance of the PC board can reach up to 89%, which can be compared with glass. The UV coated board will not produce yellowing, atomization, and poor light transmission in the sun, and the light transmission loss is only 6% after ten years, and the PVC loss rate is as high as 15%-20%, and the glass fiber is 12%-20%.

The PC board is coated with an anti-ultraviolet (UV) coating on one side and an anti-condensation treatment on the other side, combining anti-UV and thermal insulation and anti-dripping functions.

Different mechanical properties: PVC has higher hardness and mechanical properties of closed code. It increases with the increase of molecular weight, but decreases with the increase of temperature.

Hard PVC has good mechanical properties, and its elastic modulus can reach 1500-3000MPa. And the elastic MPA of soft PVC. However, the elongation at break is as high as 200%-450%.

The friction of PVC is general, the static friction factor is, and the dynamic friction factor is.

Water pipes are indispensable building materials in our daily life, and they can be seen in both construction and urban projects. However, in use, many users are confused about these two types of water pipes. So what is the difference between PE pipe and PVC pipe?

What is the difference between PE pipe ruler and PVC pipe?

The toughness and hygienic properties of PE pipes are good, while PVC pipes are poor, and they are also brittle when installed; Secondly, PE pipes need hot melt technology when they are connected, while PVC pipes are connected by glue rings and threads according to the diameter of the pipes. Finally, under the same water pressure, the PE pipe wall is not only thicker than PVC, but also more expensive.

How to choose PVC pipes:

1. Quantity: First of all, in the selection of PVC pipes, it is necessary to measure whether the wall thickness is up to standard, and it should be noted that some manufacturers use the method of evacuation in order to reduce costs, resulting in the thickness of the pipe at both ends reaching the standard, and the middle wall thickness is thinner, which cannot be used normally.

2. Look: Secondly, look at the gloss of the surface of the water pipe, the surface of the water pipe is generally oily, and the color is light beige. On the contrary, some tubes have a dull surface and are yellow and black, so it is not recommended to buy them.

Because these tubes may be made of too many miscellaneous materials or ** materials in production.

3. Weigh the weight of the pipe, it is best to weigh two pipes of the same specification, if one of them is heavier, it is not recommended to buy, it may be that too many impurities are added, and it cannot meet the use standard.

4. Fall: Finally, you can drop the PVC pipe to the ground or step on the pipe with your feet to see if the pipe is cracked or broken. If it is fragile, it means that the manufacturer has mixed too much calcium powder into the pipe in order to save costs during production, which will lead to a decrease in the hardness of the pipe.

On the contrary, whether the high-quality pipe is stepped on by foot or rolled by turning, it will only be flattened but not broken.

Summary: The above is the difference between PE pipe and PVC pipe and how to buy PVC pipe for everyone, I hope to help friends who need to know, if you need to know more about related knowledge in the later stage, welcome to pay attention to Qeeka Home information.
