　　2. The temperature range of FRP pipes with good heat resistance and frost resistance is generally between - 40 C and 80 C. If special resin is used first, the temperature will be higher.

　　FRP管的比重為1.7-1.9。與其他相同壓力和直徑的材料相比，F(xiàn)RP管的單位長度和重量約為鋼管的30%。因此，它是非常方便的運(yùn)輸和安裝。除安裝鋼管需要焊接防銹、防腐處理等程序外。

　　The specific gravity of FRP tube is 1.7-1.9. Compared with other materials with the same pressure and diameter, the unit length and weight of FRP pipe are about 30% of that of steel pipe. Therefore, it is very convenient to transport and install. In addition to installation of steel pipes need welding anti-rust, anti-corrosion treatment and other procedures.

　　玻璃鋼管內(nèi)表面光滑，粗糙度系數(shù)小。水力系數(shù)C可長期保持在145-150的范圍內(nèi)。試驗(yàn)結(jié)果表明，水流摩擦損失系數(shù)f為0.000915，可顯著降低沿程流體壓力損失，提高輸送能力20%以上。

　　5、良好的電和熱絕緣玻璃鋼是非導(dǎo)體,管道保溫很好,適合使用的傳播,電信線密度區(qū)域和雷區(qū),FRP管的傳熱系數(shù)非常小(0.25千卡/ m·h·℃),所以管的絕緣良好,更少的熱量損失。

　　5. Good electrical and thermal insulation FRP is non-conductor, pipeline insulation is very good, the most suitable for use of transmission, telecommunications line density area and minefield, the heat transfer coefficient of FRP pipe is very small (0.25 kcal/m.h.C), so the insulation of the pipe is good, less heat loss.

　　6、不生銹是因?yàn)椴ＡЧ苁怯煞墙饘俨牧蠘渲筒ＡЮw維復(fù)合而成，所以，無論是在使用過程中還是在閑置過程中，都不會(huì)生銹，所以沒有必要進(jìn)行防銹、除銹。7. 可根據(jù)具體使用情況，對(duì)纏繞玻璃鋼管的具體性能和形狀進(jìn)行設(shè)計(jì):

　　6. Non-rusting is because the glass tube is made of non-metallic resin and glass fibre.
