Q:Glass fiber reinforced plastic pipeline to do anti-corrosion?
Glass fiber reinforced plastic itself belongs to a kind of anticorrosive material, and usually needs no antiseptic treatment. However, mainly depends on the environment and requirements.
Q:What are the disadvantages of glass fiber reinforced sand pipe?
Not agree with the recommended answer, the same thickness of glass fiber reinforced plastic sand pipe and process tube, process tube stiffness is not low (can be calculated). The effect of sand inclusion is mainly to reduce the cost.
Q:Is the installation of FRP pipes required qualification?
At present, for purely glass fiber steel, there is no uniform international standards, installation workers must have qualified installation.
Q:What are the differences between inorganic FRP pipes and plexiglass pipes, what are the advantages and disadvantages?
Inorganic glass fiber reinforced plastic wind pipe: magnesium magnesite soil and glass fiber mesh cloth made of advantages: flame retardant shortcomings: large proportion, low strength
Q:What are the standards for FRP pipes?
In order to comprehensively check the installation quality of the pipeline, it is necessary to carry out a comprehensive examination according to the test methods stipulated in the code for construction and acceptance of water supply and drainage pipeline works and to carry out the water pressure test. Permissible water seepage can be carried out according to the standard of FRP pipe.
Q:What are the posts of glass fiber reinforced plastic sand pipe and the corresponding occupational hazards and protection?
Glass fiber reinforced mortar pipe lightweight high strength: for the same diameter of the unit length, weight, RPM tube only carbon steel 1/3, cast iron pipe 1/5, prestressed concrete pipe 1/10, easy transport, loading and unloading.
Q:What are the functions of glass fiber reinforced plastics?
Glass fiber reinforced plastic (FRP) is a kind of composite material which has been developing rapidly for more than fifty years. 70% of glass fiber output is used to make fiberglass. Glass steel is much harder and much lighter than steel.
Q:What are the advantages of glass fiber reinforced plastic sand pipe than HDPE pipe?
Advantages of FRP pipes:1, insulation, acid, alkali and salt corrosion, antistatic, rust, aging is not easy, the service life of up to 50 years.2, non-magnetic, non electrical corrosion, waterproof performance, and can be used in humid environment or water for a long time without deterioration.3, high strength, is the same degree of the original PE pipe is more than 6 times, light weight, smooth wall, perforated cable when the friction coefficient is small, no cable operation.4, heat resistance, antifreeze, fire protection, fire retardant type. It can be used for a long time at -35 ~ 139 degrees celsius.5. The bending modulus is good, the impact resistance is strong, and it solves the defects of metal tube easy to decay and no distortion and elasticity.6, the cable across the bridge and across the river, the use of glass fiber reinforced plastic catheter is more economical and appropriate.7, construction and installation is very simple, no need to tie steel, pouring concrete.
Q:How long is the service life of glass fiber reinforced plastic pipes?
Glass fiber reinforced plastic grille can reduce power consumption and simplify management. Galvanized grille plate adopts high efficiency and low resistance water collecting device, floating water rate is less than 0.001%, environmental protection is the best. The galvanized grating plate has the advantages of advanced structural design, optimum matching of gas and water, and sufficient heat exchange, with the same level in foreign countries and superior output. The company has a realistic, innovative research team. The galvanized grille fan adopts a tensile type of strong wind blade and long space, which is more stable when the fan is running, thereby reducing noise and greatly improving the cooling efficiency. Successively in Shanghai, Guangdong, long-term and domestic famous universities, research institutes cooperation. Hebei, Qingdao and Beijing have additional production bases and service liaison points. Willing to work with new and old customers to create a beautiful today, Chinese and foreign.
Q:Do I need CCC certification for ventilated GRP?
The air duct is made of 10MM thick fiberglass pipe, and the design of the air duct is wrong. The FRP pipe is developed for fire control and smoke exhaust.
