1、濟(jì)南排煙罩由于玻璃鋼管是由非金屬材料樹脂及玻璃纖維復(fù)合而成,所以,它們不論在使用過程還是在閑置過程中,均不會生銹,因而也就無需進(jìn)行防銹、除銹處理.

　　1, do not rust because of the glass steel pipe is made of nonmetal materials of resin and fiberglass. Therefore, both in use or in the idle process, will not rust, so there is no need for anti rust, rust treatment.

　　2、耐腐蝕性 FRP管道能夠抵抗酸、堿、鹽、海水、未經(jīng)處理的污水、腐蝕性土壤或地下水及眾多化學(xué)流體的腐蝕.

　　2. Corrosion resistant FRP pipes resist acid, alkali, salt, sea water, untreated sewage, corrosive soil or groundwater, and the corrosion of numerous chemical fluids

　　3、摩擦阻力小,輸送能力高 FRP管道內(nèi)表面非常光滑,糙率系數(shù)小,水利系數(shù)C可長期保持在145-150范圍內(nèi),經(jīng)測試得到其水流摩阻損失系數(shù)f為0.000915,能顯著減少沿程的流體壓力損失,提高輸送能力20%以上.

　　3, small friction resistance, high transmission capacity of FRP pipe inner surface is very smooth, the roughness coefficient is small, water coefficient C can be maintained in the range of 145-150 for a long period of time, is obtained by the test the water friction loss coefficient f is 0.000915, can significantly reduce the loss of fluid pressure, increase the transmission capacity of more than 20%.

　　5、耐熱抗凍性好 FRP管的溫度使用范圍一般在-40℃~80℃之間,若先用特殊樹脂其使用溫度可達(dá)到更高.

　　5, heat resistance, frost resistance is good, FRP tube temperature range of use is generally between -40 degrees ~80 degrees, and if the first use of special resin, its use temperature can reach higher

　　6、電、熱絕緣性好 FRP是非導(dǎo)體,管道的絕緣性好,適應(yīng)使用于輸電、電信線路密集區(qū)和多雷區(qū),FRP管的傳熱系數(shù)很小(0.25kcal/m·h·℃),因此管道的保溫性好,熱損失少.

　　6, electricity, heat insulation of FRP is a non conductor, pipe insulation, used in power transmission and telecommunication lines and the most concentrated area of CAAC to FRP tube heat transfer coefficient is very small (0.25kcal/m H C), so the pipeline and good insulation, less heat loss.

　　7、輕質(zhì)高強(qiáng),運(yùn)輸安裝方便 FRP管道的比重為1.7-1.9,與同壓力、同管徑的其他材質(zhì)管道比較,FRP管道單位長度、重量約等于鋼管的30%,因此運(yùn)輸安裝十分方便,FRP管道每根長度可達(dá)12m,安裝快速簡便.另外可免除安裝鋼管所需的焊接和防銹、防腐處理等工序.

　　7, light weight and high strength, convenient transportation and installation of FRP pipe accounted for 1.7-1.9, compared with other pipelines with the same diameter, pressure, weight per unit length, FRP pipeline steel is approximately equal to 30%, so the transportation is very convenient for installation, FRP pipeline per root length up to 12M, quick and convenient installation. In addition to welding and rust and corrosion protection processing process from steel pipe installation required.

　　8、可設(shè)計(jì)性強(qiáng) 根據(jù)具體使用情況,可對纏繞玻璃鋼管的具體性能及形狀進(jìn)行設(shè)計(jì):

　　8, the design can be strong, according to the specific use of circumstances, the winding glass fiber reinforced concrete performance and shape of the design:

　?、倏蓪p繞時(shí)的纏繞角進(jìn)行設(shè)計(jì),以便管具有不同的縱/環(huán)向強(qiáng)度分配;

　　The winding angle can be designed so that the tube has different longitudinal / annular strength distribution;

　　②可對管壁厚進(jìn)行設(shè)計(jì),以便管可以承受不同的內(nèi)外壓;

　　The wall thickness can be designed so that the tube can withstand different internal and external pressures;

　?、劭蓪Σ牧线M(jìn)行設(shè)計(jì),以達(dá)到不同的耐腐蝕目的、阻燃目的、介電目的等;

　　Thirdly, the material can be designed to achieve different corrosion resistance purposes, flame retardant purposes, dielectric purposes, etc.;

　　④可對授頭方式進(jìn)行設(shè)計(jì),適用不同的安裝條件,以提高工程安裝速度.

　　The design of the head way can be applied to different installation conditions so as to improve the installation speed of the project
