《揚(yáng)子晚報》報道：【勝倉管業(yè) 高經(jīng)理13730570531  QQ：2927372564】TPEP防腐鋼管具有良好的可靠性能，一般情況下普通水水管道口徑大，一旦發(fā)生爆管或漏水事故，浪費(fèi)大， 給居民造成的影響大，考慮管材質(zhì)量及承壓能力，及連接的可靠性。對自來水水質(zhì)的標(biāo)準(zhǔn)已靠近國際標(biāo)準(zhǔn)，居民對供水水質(zhì)的要求也越來越高，內(nèi)涂層為飲用水級別的管道，防止發(fā)生二次污染供水管網(wǎng)投入運(yùn)行費(fèi)用是耗電，線路長，降低管網(wǎng)運(yùn)行耗能的因素，優(yōu)先選用管道粗糙系數(shù)小的管材。【勝倉管業(yè) 高經(jīng)理13730570531  QQ：2927372564】管道的造價要從全周期的角度綜合考慮，不僅要考慮管材費(fèi)用，還要考慮管材的安裝施工，其后的運(yùn)行費(fèi)用以及使用壽命。因此TPEP防腐鋼管【勝倉管業(yè) 高經(jīng)理13730570531  QQ：2927372564】成為首選。熱收縮套包復(fù)，由于環(huán)氧粉末涂層、鋼管、熱收縮套膠層和熱收縮套聚乙烯層的膨脹系數(shù)不同，所以，即使熱收縮套施工質(zhì)量很好，也會隨著管道使用年限的增加，冬夏的交替，使熱收縮套和環(huán)氧粉末涂層產(chǎn)生分離，優(yōu)其是熱收縮套的邊緣處。為確保補(bǔ)口質(zhì)量，最好采用三層結(jié)構(gòu)熱收縮套，即在鋼管上先涂刷一層無溶劑液態(tài)環(huán)氧底漆，等底漆表干后再包復(fù)熱收縮套。【勝倉管業(yè) 高經(jīng)理13730570531  QQ：2927372564】這樣無溶劑液態(tài)環(huán)氧底漆與鋼管和管體環(huán)氧粉末層有很好的粘結(jié)力，與熱收縮套也有較好的粘結(jié)力。采用三層結(jié)構(gòu)熱收縮套補(bǔ)口，質(zhì)量容易保證，但施工工藝較復(fù)雜，造價較高。【勝倉管業(yè) 高經(jīng)理13730570531  QQ：2927372564】

"Yangtze Evening News" reported that the TPEP anticorrosive steel pipe has good reliability performance. Generally speaking, the caliber of ordinary water pipe is large. Once the pipe burst or leakage accident occurs, it is wasteful and has a great impact on the residents. Considering the quality of pipe material and bearing capacity, and connection, the TPEP anticorrosive steel pipe has a good reliability performance. Reliability. The standard of tap water quality is close to the international standard, and the requirement of water supply quality is higher and higher. The inner coat【勝倉管業(yè) 高經(jīng)理13730570531  QQ：2927372564】ing is the grade of drinking water pipeline. The operating cost of the water supply network to prevent secondary pollution is the factor of power consumption, long line and reducing the energy consumption of the network. The cost of pipeline should be considered comprehensively from the point of view of the whole cycle, not only the cost of pipe material, but also the installation and construction of pipe material, and the subsequent operation cost and service life. Therefore, TPEP anticorrosive steel pipe becomes the first choice. The expansion coefficient of epoxy powder coating, steel pipe, heat shrinkable sleeve glue layer and heat shrinkab【勝倉管業(yè) 高經(jīng)理13730570531  QQ：2927372564】le sleeve polyethylene layer is different, so even if the construction quality of heat shrinkable sleeve is good, it will also increase with the service life of pipeline, winter and summer alternate, so that heat shrinkable sleeve and epoxy powder coating produce separation, the best is heat The edge of the shrink sleeve. In order to ensure the quality of the patch, it is better to use a three-layer structure heat shrinkable sleeve, that is, a solvent-free liquid epoxy primer is first applied on the steel pipe, and the primer surface is dried and t【勝倉管業(yè) 高經(jīng)理13730570531  QQ：2927372564】hen coated with heat shrinkable sleeve. In this way, the solvent-free liquid epoxy primer has good adhesion with the epoxy powder layer of steel pipe and pipe body, and has good adhesion with heat shrinkage sleeve. It is easy to ensure the quality by using three-layer structure heat shrinkage sleeve, but the construction technology is more complicated and the cost is higher.
