What is the impact on the price of fiberglass pipes How to buy fiberglass pipes

Because of its unique performance advantages, fiberglass rod tube has been widely used in more than 10 industries related to aerospace, railways, decorative buildings, home furniture, advertising displays, craft gifts, building materials and sanitary ware, yacht berthing, sports materials, sanitation engineering, etc., and has been highly praised and has become the darling of businesses in the new era in the material industry.

Different fiberglass tubes have different properties and uses, and the different properties and uses also determine their differences**.

How to buy fiberglass pipe:

1. Touch: whether the texture is delicate and whether the particles are uniform. The quality of the tube can't solve the problem, touch it, the rough particles are likely to be mixed with other impurities.

2. Smell: whether there is a smell or not. Good pipes have no odor, while bad ones have strange smells, most likely blended with polyethylene (i.e., PE) rather than polypropylene.

3. Pinching: The glass fiber tube has considerable hardness, and it can be kneaded into a deformed tube casually, which is definitely not a PPR tube.

4. Smashing: A good fiberglass tube has good "resilience", and it is too easy to smash because there is too much calcium carbonate filler, which is naturally not a good fiberglass tube. The glass fiber pipe that cannot be smashed is not necessarily a good pipe, the key is to look at the raw materials and processing technology.

5. Burning: Igniting a fire is very intuitive and effective. The glass fiber tube mixed with ** plastic and other impurities in the raw material will emit black smoke and have a pungent odor; After burning, the good material not only does not emit black smoke and no smell, but after burning, the molten liquid is still very clean.

1. What are the models of fiberglass pipes?

Fiberglass pipe, also known as fiberglass pipe, is a new type of pipe material, it has many specifications and models, according to different pressure requirements, the models are also different, generally there are three kinds, can be customized according to the requirements of the manufacturer and customer requirements:

1. There are 20*, 25*, 32*, 40*, 50*, 63*, 75*, 90*, 110*10, 20*, 25*, 32*, 40*, 50*, 63*, 75*, 90*, 110* and other models. (Unit:.)

Key Benefits:

1. Good corrosion resistance. Because the main raw materials of glass fiber steel pipe are composed of unsaturated polyester resin and glass fiber with polymer composition, it can effectively resist the corrosion of acid, alkali, salt and other media and the erosion of untreated domestic sewage, corrosive soil, chemical wastewater and many chemical liquids, and under normal circumstances, it can maintain the safe operation of the pipeline for a long time.

2. Good anti-aging performance and heat resistance. FRP pipes can be used for a long time in the temperature range of -40 to 70, and the specially formulated high-temperature resistant resin can also work normally at temperatures above 200. For long-term use in the open air, ultraviolet absorbers are added to the outer surface of the pipeline to eliminate the radiation of ultraviolet rays to the pipeline and delay the aging of FRP pipes.

3. Good frost resistance. Below -20, there will be no freezing and cracking after freezing in the tube.

4. Light weight, high strength and convenient transportation. FRP pipes are not only light in weight, high in strength, strong in plasticity, easy to transport and install, but also easy to install various branch pipes, and the installation technology is simple.

5. Good hydraulic conditions. The inner wall is smooth, the conveying capacity is strong, no scaling, no rust, and the water resistance is small.

6. Good designability. FRP pipes can be designed and manufactured into pipes with different pressure levels and stiffness levels according to various specific requirements of users, such as different flow rates, different pressures, different burial depths and load conditions.

7. Low maintenance cost. Due to the above-mentioned corrosion resistance, wear resistance, frost resistance and anti-fouling properties, the project does not need to carry out rust prevention, anti-fouling, insulation, thermal insulation and other measures and maintenance. There is no need for cathodic protection for underground pipes, which can save more than 70% of engineering maintenance costs.

8. Good wear resistance. Water containing a large amount of mud and sand is loaded into the pipe for a comparative test of the effect of rotational wear. After 3 million rotations, the wear depth of the inner wall of the test tube is as follows:

Steel pipes coated with tar and enamel, steel pipes coated with epoxy resin and tar, and steel pipes treated with surface hardening are glass fiber reinforced plastic pipes. As a result, FRP has good wear resistance.
