Method for distinguishing PE water supply pipe and drainage pipe
PE管的客户从外观根本区分不出来PE给水管和排水管，那如何PE给水管和排水管到底有何区别呢？ Generally , customers who do not understand PE pipes can't distinguish PE water pipes and drainage pipes from the appearance. So how is the difference between PE water pipes and drainage pipes?
材料 I. Materials
国家卫生标准， 它 的原料也必须是符合国家标准的高密度聚乙烯。 PE water supply pipe must meet national sanitary standards, and its raw materials must also be high-density polyethylene that meets national standards. 自来水供人们日常生活用水 。 Only when these two standards are met can tap water be supplied for people's daily use .
PE排水管 的 用途是排放污水，所以只要是可降解、不污染环境就可以了，一般经过客户的允许， 还 可以加入一些回料进行生产。 The purpose of the PE drainage pipe is to discharge sewage, so as long as it is degradable and does not pollute the environment, it is generally possible to add some recycled materials for production after customer's permission .
压力 Second, the pressure
所以 PE给水管需要承受住泵抽水时的压力 。 The PE water pipe needs to pump water from the ground to the ground to transport tap water, so the PE water pipe needs to withstand the pressure when the pump is pumping water . 压力的大小，一般将 PE给水管分为五个等级，分别是0.6Mpa，0.8Mpa，1.0Mpa，1.25Mpa，1.6Mpa。 According to the size of the pressure, the PE water supply pipe is generally divided into five levels, which are 0.6Mpa, 0.8Mpa, 1.0Mpa, 1.25Mpa, 1.6Mpa. The higher the pumping pressure, the higher the pressure level of the PE feed pipe required.
PE排水管一般是排放污水，从高处往低处自流的，所以PE排水管一般不需要考虑压力等级。 The PE drainage pipe generally discharges sewage and flows from high to low, so the PE drainage pipe generally does not need to consider the pressure level.
Third, the price
价格 会比 PE排水管高。 The PE water supply pipe is more expensive than the PE drainage pipe because it uses a new high-density polyethylene material .
