玻璃鋼管的好處
Abstract: the protection tube of glass reinforced plastic cable is based on resin, and the continuous glass fiber and its fabric are reinforced materials, which can be controlled by the computer to control the winding process or the forming of the extrusion process.
與其他材質(zhì)的管道比較,玻璃鋼管道具有以下一些顯著的優(yōu)點(diǎn):
Compared with other materials, fiberglass pipes have the following advantages:
(1)耐腐蝕性好。玻璃鋼管道能抵抗酸性、堿性流體,非流體的侵蝕,在一般情況下,鋼管使用年限為15年,鑄鐵管為5–10年,而玻璃鋼管可使用50年。
(1) good corrosion resistance. The glass steel pipe can resist acid, alkaline fluid, and non-fluid erosion. Under normal circumstances, the length of steel tube is 15 years, the cast iron tube is 5 to 10 years, and the glass tube can be used for 50 years.
(2)防污抗蛀。不飽和聚脂樹(shù)脂的管道表面潔凈光滑,其特殊介質(zhì)不會(huì)被菌類等生物玷污蛀腐,例如,鋼管、鑄鐵或鋼筋混凝土管道,表面易被微生物附蛀而且難以清除,以致增大粗糙率,減少過(guò)水?dāng)嗝。而玻璃鋼管道在避光情況下不會(huì)產(chǎn)生微生物,因此無(wú)污染,長(zhǎng)期使用潔凈如初。
(2) antifouling and mothproofing. Unsaturated polyester resin pipe clean smooth surface, its special medium will not be decay fungi and other biological defiled decayed, for example, steel pipes, cast iron or steel reinforced concrete pipe, surface vulnerable to microbial decay and difficult to remove, so that increase the rough rate, reduce water section. And the glass steel pipe will not produce microorganism in the light of the light, so it is free of pollution and long term clean.
(3)耐熱性、抗凍性能好?扫C40℃—80℃的范圍內(nèi)長(zhǎng)期使用,若采用特殊配方的樹(shù)脂可在110℃以上的溫度下工作。
(3) good heat resistance and cold resistance. Can - 40 ℃, 80 ℃ within the scope of use for a long time, if the use of special formula of resin can work under the temperature of above 110 ℃.
(4)工程壽命長(zhǎng),安全可靠。管道經(jīng)久耐用,安全系數(shù)在6以上。其管道壽命達(dá)可長(zhǎng)達(dá)50–100年。例如,由深圳至香港的供水工程在香港一側(cè)建成的引水管道,長(zhǎng)50KM,分別為兩種內(nèi)徑2.2m和1.7m的玻璃鋼管道,從1965年安裝使用至今扔完好無(wú)損。
(4) long life and safety and reliability. The pipeline is durable and the safety factor is above 6. Its pipeline can last 50 to 100 years. From shenzhen to Hong Kong, for example, built in the water supply project in Hong Kong side of the water diversion pipe, 50 km long, two kinds of inner diameter of 2.2 m and 1.7 m respectively of FRP pipes, installed in 1965 still intact.
(5)自重輕、強(qiáng)度高、運(yùn)輸安裝方便。玻璃鋼管道的比重約為1.8,管道的環(huán)向拉伸強(qiáng)度為100–200Mpa(接近于鋼管),軸向拉伸強(qiáng)度為320Mpa。玻璃鋼管道每根有效長(zhǎng)度可達(dá)12m,較混凝土管道可減少三分之二的接頭。單、雙密封承插式連接,安裝快速簡(jiǎn)便,施工工期比鋼管、鑄鐵管、混凝土管可縮短1/3,且免除安裝鋼管所需的焊接和防銹等煩瑣工序。
(5) light weight, high strength, convenient transportation and installation. The proportion of the glass steel pipe is about 1.8, the loop of the pipe has a tensile strength of 100 to 200Mpa (close to the steel pipe), and the axial tensile strength is 320Mpa. The effective length of the glass steel pipe can reach 12m, and it can be reduced by two thirds compared with the concrete pipe. Single, double seal socket connection, quick and easy installation, the construction period of steel tube, cast iron pipe, concrete tube can be shortened by 1/3, and avoid the installation of steel tube required welding and anti-rust and so on.
(6)摩阻力小,輸送能力高。玻璃管道內(nèi)表面非常光滑,粗糙率(0.0084)和摩阻力很。ㄟh(yuǎn)小于鋼管和鑄鐵管的粗糙度)。計(jì)算水力學(xué)所采用的哈森威廉(Hazen-Williams)系數(shù)C可以長(zhǎng)期保持在145–150的范圍內(nèi),測(cè)試得到其水流摩阻損失系數(shù)f為0.000915,較混凝土管(f=0.00232)和鋼管(f=0.00179)能顯著減少沿程的流體壓力損失,提高輸送能力20%以上。因此,在輸送能力相同時(shí),工程可選用內(nèi)徑較小的玻璃管道,從而降低一次性的工程投入;若采用同等內(nèi)徑的管道,玻璃鋼管道可比其他材質(zhì)管道減少壓力損失,即節(jié)省泵的功率和能源(約30%–40%),降低長(zhǎng)期的運(yùn)行費(fèi)用。
(6) small resistance and high throughput. The inner surface of the glass tube is very smooth, the rough rate (0.0084) and the friction resistance are very small (far less than the roughness of the steel tube and cast iron pipe). Adopted by the computing hydraulics Hazen William (Hazen - Williams) coefficient C can keep for a long time in 145-150 range, testing the flow friction loss coefficient is 0.000915, f (f = 0.00232) and a concrete pipe steel pipe (f = 0.00179) can significantly reduce the fluid pressure loss along the path, improve the transmission capacity of more than 20%. Therefore, in the same time, the engineering can choose the small inner diameter glass pipe to reduce the one-time project input. If the pipe with the same inner diameter is used, the glass steel pipe can reduce the pressure loss compared with other materials, which is to save the power and energy of the pump (about 30% to 40%), and reduce the long-term running cost.
(7)電、熱絕緣性好。玻璃鋼是絕緣體,管道的電絕緣性能優(yōu),最適合使用于輸電線、電信線路密集區(qū)和多雷區(qū);玻璃鋼的傳熱系數(shù)很。0.25kcal/m?h?℃),管道的保溫性能良。耐磨性好。把含有大量泥漿、沙石的水,裝入管道中進(jìn)行旋轉(zhuǎn)磨損影響對(duì)比試驗(yàn)。經(jīng)300萬(wàn)次旋轉(zhuǎn)后,檢測(cè)管道內(nèi)壁的磨損程度如下:用焦油和瓷釉涂層的鋼管為0.53mm;用環(huán)氧樹(shù)脂和焦油涂層的鋼管為0.52mm;經(jīng)表面硬化處理的鋼管為0.48mm;玻璃鋼管為0.21mm。由此可以說(shuō)明其相當(dāng)耐磨。
(7) good electrical and thermal insulation. The glass steel is an insulator, and the insulation performance of the pipe is excellent. It is suitable for use in power lines, telecommunication lines and multi-minefields. The heat transfer coefficient of glass steel is very small (0.25 kcal/m? H? ℃), the pipe heat preservation performance is good. Good wear resistance. Test the impact of rotating wear in the pipe by water containing a large amount of mud and sand. After 3 million rotation, the wear of the inner wall of the test tube was as follows: steel pipe with tar and enamel coating was 0.53 mm; Steel pipe with epoxy resin and tar coating is 0.52 mm; The steel tube treated with surface hardening is 0.48mm; The glass tube is 0.21mm. This shows that it is quite wear-resistant.
(9)工程維修簡(jiǎn)便節(jié)約。玻璃鋼管道由于上述的耐腐蝕、耐磨和抗凍、抗污等性能,因此工程不需要進(jìn)行防銹防蝕、防污、絕緣等措施。對(duì)地埋管無(wú)需作保護(hù),可節(jié)約工程維護(hù)費(fèi)用70%以上。如遇到意外的破壞也很容易修復(fù)。
(9) simple maintenance of engineering maintenance. Because of the corrosion resistance, wear-resisting and anti-freezing, anti-fouling and other properties of the fiberglass pipe, the project does not require anti-rust, anti-corrosion, anti-fouling, insulation, etc. There is no need to protect the buried pipe, and can save more than 70% of the cost of maintenance. It is also easy to repair if there is an accident.
