Q:Can FRP pipes be used in heating pipes?
FRP pipes are generally not used in heating pipes, because the use temperature of FRP pipes is limited, as detailed below:1. universal unsaturated polyester FRP can only be used for less than or equal to 60 degrees (HG/T20696-1999)2. bisphenol A unsaturated polyester FRP can only be used for less than or equal to 100 degrees HG/T20696-1999)3. vinyl unsaturated polyester glass fiber can only be used for less than or equal to 120 degrees HG/T20696-1999)4. epoxy FRP can be used for less than or equal to 90 degrees HG/T20696-1999)5. glass fiber reinforced plastic sand holding pipes can only be used for less than or equal to 50 degrees (GB/T21238-2007)
Q:What kind of material is the pipe of the pipe that installs the pressure transmitter of GRP conduit? Is it fiberglass or carbon steel?
It is generally assumed that it is made of glass fiber reinforced plastic. The main pipe is made of glass fiber reinforced plastic. The medium is corrosive. Other materials must not be suitable
Q:What's the process of continuous winding glass fiber reinforced plastic sand pipe?
(1) die: the continuous flat steel supported by the reel, winding to form a round mandrel.(2) feeding: when the mandrel moves, advanced packing, glass fiber, resin and surface material are accurately placed under the control of program control (PLC) and microcomputer (PC).(3) monitoring: according to the prepared material input program, only the basic pipeline data can be input; the computer can calculate the mechanical operation settings by itself. Material consumption, pipe thickness and so on will be constantly monitored and recorded.(4) curing: induction heating of the curing process of the product is accomplished by the flat band and the infrared device which is directly heated in the product. The temperature of 20 different parts of the product in the curing zone will be measured and displayed in the form of an image on the computer screen.(5) cutting and trimming: the pipe can be cut from 0.3 meters to 18 meters under the predetermined length. The cutting, chamfering and caliber measurement are coordinated with the longitudinal movement of the product to ensure the accurate vertical cutting of the glass fibre reinforced plastic pipe and the killing of the outer diameter.
Q:How to install FRP pipe correctly
Field bonding process is usually provided by glass fiber reinforced plastic manufacturers, if there is no way, I can provide some experience for reference, there is little information, experience only.
Q:The difference between FRP process tubes and GRP tubes
Process tubes are mostly pure glass steel, not sand, and sand pipe, of course, is added sand.
Q:What are FRP pipes made of?
The wall of the pipe is smoothReduce flow resistance, increase flow speed and reduce energy consumption. Compared with the same size steel pipe, the flow rate of the same volume can be increased by about 10%, and no fouling and long-term use can not reduce the flow rate. The protection of cables in interference and heavy corrosion environment is better.
Q:Which is better, pultruded FRP square pipe with PVC?
Wear-resistant pipeline transportation has been in the power, metallurgy, coal, petroleum, chemical, building materials, machinery and other industries, and high-speed development.
Q:Who knows, how is the glass reinforced septic tank connected with the municipal pipe?
Septic tank (Hu, F, NCH) is the treatment of nightsoil and to filter precipitation equipment. The principle is that the cured material decomposes at the bottom of the tank, and the upper hydration object flows into the pipeline to prevent the pipe from clogging and has enough time to hydrolyze the solidified object (such as excrement and urine). Tank (septic) refers to the division of living sewage sludge, and anaerobic digestion of sludge structure of small structures.
Q:What are the advantages of FRP pipes?
As a result, aviation, rockets, aerospace vehicles, high pressure vessels, and other applications that need to reduce weight have excellent results. The tensile, flexural and compressive strengths of some epoxy FRP can reach over 400Mpa.
Q:What kind of material does glass steel ship honeycomb board use?
Analysis of glass steel tube and glass steel tube cellular communication used in communication network construction, is currently used PVC bellows and PVC honeycomb tube, pipe and pipe crossing is the use of plastic pipe or galvanized steel pipe.
