The complete form of FRP is fiberglass reinforced plastic, which is a composite material composed of a fiber-reinforced polymer matrix. Therefore, FRP pipes are made of FRP materials through contact molding or fiber winding. Various types of resins, such as thermosetting polyester, epoxy, phenolic resin, etc., are used to obtain the final product with specific FRP pipe properties. As a corrosion-resistant metal pipe substitute, FRP piping system has been widely used worldwide. By choosing FRP as the pipe material, the need for lining, external coating and cathodic protection can be easily eliminated.

Application of fiberglass reinforced plastic pipe
Due to the high durability, corrosion resistance and medium strength of FRP pipes, its use is increasing day by day. FRP piping systems are used in different industries, such as:
&#;Drinking water and seawater desalination industry
&#;Chemical, petrochemical, oil and gas industries.
&#;Pipes and exhaust pipes
&#;Irrigation and sanitation services
&#;Water distribution and delivery
&#;Mud pipeline
&#;Power plants, etc.
Performance of FRP pipe
The main performance of FRP pipe is to make it an ideal choice for various industries in the world.
&#;Excellent corrosion resistance
&#;Excellent strength-to-weight ratio. It is worth noting that the strength-to-weight ratio of FRP pipes is higher than that of steel or other metal pipes.
&#;Light weight, easy to handle and transport.
&#;Dimensional stability
&#;Degradable
&#;Low friction coefficient (>25% better than steel), ensuring good flow characteristics.
&#;Good abrasion resistance
&#;Suitable for ground and underground pipelines
&#;Resistance to biological attacks such as bacteria
&#;Non-conductive
&#;Low maintenance cost
FRP pipe connection
Since the length of the FRP pipe is restricted by transportation and handling, it needs to be connected. At the same time, various FRP pipe fittings need to be connected as required. The connection system of the FRP pipe shall ensure that no leakage occurs under the predetermined use conditions under the working pressure.
FRP pipe fittings
Various FRP pipe fittings are available to meet the needs of pipeline layout. Common glass steel pipe parts are:
&#;Long radius, short radius FRP elbow
&#;Tee connection (equal tee and reducing tee)

FRP pipe specifications
When ordering FRP pipes, the following information must be provided to the supplier:
&#;Pipe diameter
&#;The design and working temperature of the applied fluid.
&#;Design, operation, surge, vacuum, test pressure.
&#;Live load of buried pipelines.
&#;Maximum/minimum buried depth and trench width.
&#;Details of soil properties and trench preparation.
Disadvantages of FRP pipes
The main disadvantage of FRP piping system is:
&#;It is not recommended to use FRP pipes to transport fluids whose temperature exceeds 100°C
&#;The use of pigments, dyes, UV stabilizers, fillers, etc. in the resin system can reduce the slight degradation of the resin by ultraviolet light.
Who hasn&#;t purchased something at a relatively low price and then something went wrong, leaving us wishing we&#;d bought the item that was priced a bit more, but probably would have given us better service? If it was an article of clothing, maybe it shrunk after just a couple washings; if it was a new car, maybe it broke down after only a year or two. Whatever, the principal is the same &#; we sometimes regret the purchase of low price items. And in our never-ending quest to save every dollar, we regret those low price purchases more often than we want to admit.
In the FRP tank & pipe industry, the old adage &#;You get what you pay for&#; has truth to it. The industry is too competitive for any one fabricator to take advantage of overpricing by others; all the fabricators are trying to price their products attractively. If there are multiple quotes for the same project and one of them is significantly lower priced, then something may be amiss, such as the quote scopes are different. Is delivery included in the lower priced quote? Was a cheaper resin selected? Was a different specification chosen? Are the designs the same between fabricators? There are no shortcuts when quality is on the table, so how can one price be significantly lower than the others?
Custom engineered FRP vessels and pipes are complex. There is no &#;commodity&#; product with super low prices that come with mass production. When you shop for a fabricator, important elements such as engineering, delivery, warranty, maintenance, etc. should be considered in addition to price. When comparing fabricators, you need to be knowledgeable enough to compare the offerings on an apples to apples basis.
It&#;s ironic because when the low price items fail, it costs money to either repair or replace them. Quite often, when the cost of repair or replacement is added to the low purchase price, the total cost exceeds what we would have spent on a higher priced item.
For that reason, FRP tanks and pipes are like clothing and cars; low purchase price rarely equates to low total cost over time. If you want to be a smart buyer of FRP assets, think low total cost, not just low purchase price. Run the numbers on your situation to determine how much more money you&#;ll have to spend if the low priced tank lasts half as long as the higher priced tank.
What kind of buyer are you? Are you always looking for the lowest price? Or do you put your trust in a brand you know will be a fair deal this time and next time?
