Lefaʻasologa o le fiberglass tubeis e faʻamalolo ai le fiberglass which is impringnated resin i totonu o se masini vailaʻau vilivavavave-integrated-polymerization, ma toso pe tusi i totonu o se mamanu.Ona o ituaiga eseese o resini o loʻo faʻaaogaina, ua lauiloa o le polyester fiberglass, o le fiberglasslass, ma le fiberglass.Ilsoʻo se uiga ma ona faʻasinomaga o loʻo taua i lalo:
1.O le malosi o le pala o le tino. O le fiberglasstube e mafai ona puipuia lelei le faaleagaina o le suka, alkali, masima ma isi laasaga ma faʻasalaga ole fale, otaota palapala, vailaʻau eletise ma vailaʻau eletise. I lalo o tulaga masani, e mafai ona tumau le saogalemu i taimi uumi.
2.Good aging resistance and heat resistance. Glass fiber tube can be used in the temperature range of -40°C～70°C for a long period of time. Lespecial high temperature resistant resin can also work normally at temperatures above 200°C.
3. faʻafeiloaʻi le teteʻe. I lalo -20 ° C, e le tupu i luga o vaovao le papa.
4. light weight, high strength. Lerelative density is between 1.5 and 2.0, only 1/4 to 1/5 of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel, and the specific strength can be compared with that of high-grade alloy steel. Therefore, it has excellent results in aviation, rockets, spacecraft, high-pressure vessels, and other applications that need to reduce its own weight.
6. faʻafeiloaʻi le malosi. O loʻo i ai se aofaiga tele o palapala, oneone ma vai, i totonu o le tumutumu mo le suiina o le rotation ma le faʻatusatusaga o faʻatusatusaga. A maeʻa le 3 miliona suiga, o le loloto o le ofuina i le pito i totonu o le suʻega faataitai e pei ona taua i lalo: 0.53 mm faʻamalosi ma faʻamaʻi uʻamea, 0.52 mm mo uila-ma uamea uamea, ma uamea tioata-sila mo luga- faʻamau faʻamaʻa. O le 0.21mm lenei.
7.good thermal insulation. FRP is non-conductor, and its electrical insulation
is excellent. Leinsulation resistance is between 1012-1015Ω.cm. It is most
suitable for use in transmission. Leheat transfer coefficient of glass fiber
reinforced plastic area and multi-dose mine area is very small, only 0.23. In
five points, the pipeline has excellent insulation properties.
8.small friction resistance, high transmission capacity. Leinner wall of the glass pipe is very smooth, and the roughness and frictional resistance are very small. Lecoefficient of roughness was 0.0084, while the concrete pipe had an n value of 0.014 and a cast iron pipe of 0.013.
