Why Do You Need FRP Sewer Pipes?
Strong and Durable
FRP sewer pipes have high mechanical strength. It can well withstand the impact of different flow rates and water pressure when the liquid flows, without rupture or bursting. The performance is reliable and can provide a longer service life.
Corrosion Resistant
FRP is a chemically inert material. As sewage from petrochemical or other fields may have corrosive chemicals, FRP sewer pipes can well resist these impacts. They will not cause chemical reactions or corrosion in the process of use, resulting in changes in structure and properties, to ensure the stability of long-term use.
Lightweight
FRP material is lightweight and will not add the burden of handling and installation. Thus FRP sewer pipes can significantly save the labor waste and time, money costs brought by the installation.
Weather Resistant
FRP sewer pipes are highly resistant to UV rays, high and low temperatures. So even when they are used outdoors, you don’t need to worry about structural or performance damage. It also doesn’t require frequent maintenance, which saves you the effort and cost of maintenance.
FRP Vs PVC, Which Is Better For Dealing With The Sewer?
A Comparison Between FRP And PVC
| Features/Types | FRP | PVC |
| Strength And Durability | Better impact resistance and toughness | Durable material, but not as strong as FRP |
| Weight | A light material | Lighter than the FRP |
| Corrosion Resistance | Better corrosion resistance | Has good resistance to corrosion, but the ability is lower than the FRP. |
| UV Resistance | Better | If exposed to UV light for a long time, the material is likely to deteriorate or even become brittle, and the color may fade. |
| Fire Resistance | Better | Does not perform as well as FRP in areas of high fire risk. |
| Price | Higher | Lower |
How To Choose the Right One?
If the sewer pipe is to be laid outdoors or exposed to corrosive environments, FRP pipe is a better choice.
On the other hand, if the sewer pipe does not need to be exposed to direct sunlight in an outdoor environment and is less corrosive, PVC sewer pipe is sufficient. This is also a good choice after considering the cost and performance.
What Should I Pay Attention To When Installing FRP Sewer Pipes?
Check The Pipes Before The Installation
Before the actual installation, you need to take a necessary inspection of the FRP sewer pipes. First of all, you need to check the appearance of the pipe to make sure that there are no cracks, bubbles or other defects on the surface.
Secondly, it is also necessary for you to confirm its specification parameters such as thickness and dimensions. You should ensure that these values do not deviate by more than 0.5% from the figures indicated on the parameter sheet, in order to ensure that the joints are of accurate length and tightly connected.
Cleaning Of Trenches For Laying Pipes
Before placing the FRP sewer pipes, you will also need to clean the trench where the pipes will be laid. The trench must be flat enough to ensure the stability of the pipe laying. At the same time, it is better not to have stones and other debris in the trench, to avoid the scratch on the pipes surface or even the accidents of sewage leakage in the subsequent use.
Confirm The Connection Method
The splicing of FRP sewer pipes also needs to be confirmed. For example, when you use FRP flanges for installation, you need to pay attention to that the the sealing ring of the flanges must be in the center position to ensure uniform force. If you use adhesive for splicing, you need to mix the adhesive evenly and ensure that the thickness of the application is consistent.
What Are The Things To Check After The Construction Of FRP Sewer Pipe Is Completed?
Checking the Tightness of FRP Sewer Pipes Connections
When your FRP sewer pipes have been connected and installed, you should first focus on checking whether the connections of each pipe are tight or not. as the slightest gap may cause accidents in subsequent use. What you need to pay most attention to is whether the parts connected using tees, flanges, and elbows are strong and tight, and to observe whether there are any cracks in the pipe wall due to stress.
Pressure Rating Confirmation
You can check the pressure rating of FRP sewer pipes by hydrostatic testing. This is done by injecting a stream of water into the FRP sewer pipe at a pressure of 1.5 times the design water pressure of the pipe itself. If no leakage occurs during this period, the pipe passes the test. If the pipe can be kept without leakage for 30 minutes, it passes the test.
Tips To Find The Best FRP Sewer Pipe
Check the Quality of the Raw Materials
The selection of FRP sewer pipes can start with the identification of raw materials. Generally, FRP sewer pipes use a resin base material of phenyl/vinyl/phenolic resin, and the reinforcement material includes glass fiber, quartz sand and some necessary additives.
You need to make sure that the factory you choose has a quality control process for these raw materials. And it is also important to confirm the purity of the glass fibers used, so that the manufacturer does not mix them with other materials that could affect the final performance of the product.
Check the Structure of FRP Sewer Pipes
You also need to know whether the structure of FRP sewer pipes is reliable. The lining layer is the part that comes into direct contact with the sewage, so it is important to make sure that the resin material is compatible with different sewage properties (corrosiveness, temperature).
For the structural layer, it is best to choose a pipe that has undergone a computer-controlled winding process to create the wall structure, which ensures accuracy and consistency for large orders. In addition to this, if the quartz sand is added to the structural layer, you need to make sure the quartz sand is distributed evenly enough.
The outer layer is the part of the pipe that needs to protect the entire pipe, and it needs to be resistant to abrasion, UV rays, and more to provide solid protection against external factors that can cause the outer layer to hang up or even cause the pipe to rupture.
Checking the Temperature Resistance Standard
You will also need to check the temperature range of the actual fluid being transported and select a resin material with the appropriate operating temperature. For more specialized chemical applications, FRP sewer pipes may need to be operated at temperatures of 150°C or higher.
Judging the Factory’s Production Capacity
The production capacity of the factory is also a key judgment factor for selection. You need to confirm the formality and professionalism of the producer and check its business qualification. It is better to choose a factory that can provide one stop service from raw materials to design and processing. In addition, understanding their past case experience can also assist you in your judgment.
