Themyndunarferli fiberglasröra til að lækna fiberglassið sem er gegndreypt plastefni í fjölliðunarbúnað fyrir ljósvökva og samþykkja það eða draga í mótun.Vegna mismunandi tegundir af plastefnum sem notuð eru, er það þekkt aspolyester fiberglass, epoxý fiberglass og phenolic fiberglass.It hefur mallir einkenni og meginatriði þess eru sem hér segir:

 


1.Góð tæringarþol. Fiberglasstube getur í raun komið í veg fyrir tæringu á sýru, basa, salti og öðrum fjölmiðlum og ómeðhöndluðum heimilisrennsli, ætandi jarðvegi, frárennslisvatn og margfalda vökva. Undir venjulegum kringumstæðum er hægt að viðhalda langtímaöryggi.

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. Thespecial high temperature resistant resin can also work normally at temperatures above 200°C.

3.góð frostþol. Undir -20 ° C, koma ekki sprungur í rörunum.

4. light weight, high strength. Therelative 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.góð klæðast viðnám. Haltu miklu magni af drullu, sandi og vatni, í pípu fyrir snúnings slit og áhrifamælingarpróf. Eftir 3 milljón snúninga er dýpt slitans á innri vegg prófunarrörsins sem hér segir: 0,53 mm fortar og enamelhúðuð stálrör, 0,52 mm fyrir epoxý- og tjarahúðuðu stálpípur og glerstálrör fyrir yfirborðs- hertu stálrör. Það er 0,21 mm. Þetta gerir FRP slitþol.
7.good thermal insulation. FRP is non-conductor, and its electrical insulation is excellent. Theinsulation resistance is between 1012-1015Ω.cm. It is most suitable for use in transmission. Theheat 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. Theinner wall of the glass pipe is very smooth, and the roughness and frictional resistance are very small. Thecoefficient of roughness was 0.0084, while the concrete pipe had an n value of 0.014 and a cast iron pipe of 0.013.
