另一方面,设计师也会考虑将水管嵌入墙体的隔断中,提供建筑的美感。因此,专业工程师应在局限性的基础上,认真考虑使用的材料。1.2c不同类型水管对人体的危害影响从根本上讲,所有水管的产品都要经过研究、试验、合格,并在理论上安全,供人类采用。但这4种化学反应会升高并产生危害,这取决于温度、水质(如氢离子浓度(pH)和硬度)。其次,用于管道和管件连接的连接材料,如适用于铜或不锈钢管道的焊接材料,以及适用于热塑性塑料管道工作的溶剂型水泥,也会向水中排放有害物质,对人体有害。除此之外,水垢还会在水中发现大量的铁颗粒,尤其是在镀锌钢管(G.I.钢管)上。

它还会产生床上的气味,影响使用者的舒适性。因此,在选择合适的材料作为饮用水管道,以提供可靠、有保障的配水系统时,还应评估其危害影响。1.2d不同类型水管的资本价值不同材料在市场上有其价值。通常情况下,热塑性管会比金属管稍便宜,因为不同的稀有材料。在一些国家,铜管几乎是由回收的废料制成的,而且是一种丰富的资源,所以铜管的市场价格会相对便宜一些。实际上,价值不仅仅体现在材料的成本上。在不同的管道工程上进行安装,人力资源是一个本质上的问题,在采用材料时,会直接影响到材料的价值,因为有些材料需要特殊的技术、工具和安装过程的限制。因此,人工成本是材料选择价值的主要考虑因素。

On the other hand, the designer would also consider to embedding the water pipe into the wall partition to providing the aesthetic in the building. Hence, the appropriated material shall be seriously considered by the professional engineer base on the localized limitation. 1.2c Hazard Influence to Human Body for Different Types of Water Pipe By the fundamental, the products of all water pipe should be under studied tested, qualified and theoretically safe for human to adopt to do so. Unfortunately, the 4 chemical reactions would be raise and become harmful and it was depended on the temperature, water quality (such as hydrogen ion concentration (pH) and hardness). Secondly, the jointing material for the pipe and fitting connection such as the soldering materials applying in copper or stainless steel pipe, and the solvent cement applying in the thermoplastics pipe work would also be emits hazardous substance into the water to against the human. Other than that the scaling would found the large amount of iron particles in the water especially on the galvanized steel pipes (G.I. pipes).

It would also produce the bed smell and affecting to the human comfort for the user. Therefore, the hazard influence shall also be evaluating for selecting an appropriate material as the drinking water pipe to providing a reliable and assured distribution system. 1.2d Capital Value on Different Types of Water Pipe The different materials has their value on the market. Normally, the thermoplastic pipe would slightly cheaper than the metallic pipe due to the different rarity of the material. In some countries, the copper pipe almost made by the recycled scrap and is an abundant resource, so the market price of copper pipe would relatively cheaper. Actually, the value would not only mention on the cost of that material. The manpower resource for installation on different pipe work would essentially concern and it would directly affect to the value when adopting the material since some of the material should involve in special technique, tools and limitation on the installation procedure. Therefore, the labor cost is the major concern on the value of selecting the materials.
