| 供水管道特点 Characteristics of water supply pipeline 铸铁管经久耐用，比钢管锈蚀缓慢，但质脆，使用铸铁量大。 Cast iron pipe is durable, corrosion is slower than steel pipe, but the quality is brittle and the amount of cast iron used is large. 焊接钢管优点是强度高，耐高压、震动，重量较铸铁管和水泥压力管轻，缺点是易生锈，抗腐蚀性较铸铁管差。 The advantages of welded steel pipe are high strength, high pressure resistance and vibration resistance. The weight of welded steel pipe is lighter than that of cast iron pipe and cement pressure pipe. 钢筋混凝土管按生产工艺不同分自应力钢筋混凝土管和予应力钢筋混凝土管，用橡胶圈接口，具有表面光滑，不结垢的优点。缺点是自应力较重，表面及承插口怕碰撞。 The reinforced concrete pipe is divided into self stress reinforced concrete pipe and pre stress reinforced concrete pipe according to different production process. The rubber ring is used to connect the pipe, which has the advantages of smooth surface and no scaling. The disadvantage is that the self stress is heavy and the surface and socket are afraid of collision. 塑料管有聚乙烯和聚丙烯两种，无毒，耐腐蚀，接口容易，重量较别的供水管请，不结垢，价格便宜。缺点是强度低，刚性差，热胀冷缩大，在日光下老化速度加快，易断裂。 There are two kinds of plastic pipes: polyethylene and polypropylene. They are nontoxic, corrosion-resistant, easy to connect. The weight of plastic pipes is lower than that of other water supply pipes. They do not scale and are cheap. The disadvantages are low strength, poor rigidity, large thermal expansion and cold shrinkage, accelerated aging speed under sunlight, and easy to fracture. 玻璃钢供水管道具有无毒无污染，抗腐能力强，质轻强度大，耐高温，表面光滑易清洗，可用寿命长达50年以上点，但是价格就比其他管道稍微贵点。 Fiberglass reinforced plastic (FRP) water supply pipeline has the advantages of non-toxic, pollution-free, strong corrosion resistance, light weight, high strength, high temperature resistance, smooth surface, easy to clean, service life of more than 50 years, but the price is slightly higher than other pipelines. |
