问：塑料管材和传统管材的口径称谓有何不一样？
Q: plastic pipe and traditional pipe diameter Title Why not?
答：传统管材有3分、4分、6分；1寸、2寸、2寸半以及1/2英寸、3/8英寸、4/3英寸等称号。新式塑料管材通常不这么称号，而是直接用管径尺度来断定，如32、63、300、450等。某些管材也选用内外径一起称号，如铝塑复合管的1216、1620等。
A: the traditional pipe has 3 points, 4 points, 6 points; 1 inches, 2 inches, 2 inches and 1/2 inches, 3/8 inches, 4/3 inches, etc.. The new plastic pipe is usually not so title, but directly with the pipe diameter to determine, such as 32, 63, 300, etc.. Some pipes are also used in the internal and external diameter of the title, such as aluminum composite pipe 1216, 1620, etc..
问： PE给水63级、80级、100级是怎样区别的？为何63级的报价最高？
Q: PE water level 63, level 80, level 100 is how to distinguish? Why is the highest price 63?
答：依据原资料在平等环境下的耐压等级（首要选用静液压试验断定）并圆整后乘以10来区分的。例如某种资料的试验压力为9.99Mpa，通过圆整后乘以10就为100级。
Answer: according to the original data in the equal environment pressure levels (that first round selection and hydrostatic testing) multiplied by 10 to distinguish. For example, the test pressure of a certain material is 9.99Mpa, after the round by 10 multiplied by the level of 100.
等级越高，通常来说在平等的压力适用管材上壁厚就越薄，63级商品因壁厚较厚，资料用量较多，故报价较高。
The higher the level, usually in the application of equal pressure on the wall thickness of the thinner, the 63 tier products because of thick wall thickness, the amount of data is more, so the higher the price.
问：啥是规范尺度比？
Q: what is the normative scale?
答：管材的公称外径与公称壁厚的比值。
Answer: the ratio of nominal diameter and nominal wall thickness.
问：啥叫管材的圆度？
Q: what is the roundness of the pipe?
答：所谓圆度，即是任一封闭形状的外接圆与此形状的面积的差值，和此外接圆面积的比值。数值越小，阐明此形状越挨近圆。关于管材来说，特别是大口径的给水、排水管，对圆度都是有必定请求的，也即是咱们常说的管道看起来有些扁，可是如果在必定范围内契合圆度请求时都应该是没有问题的。
Answer: what is the difference of circle roundness, shape and the shape of any closed area, and the ratio of the area of the circle. The smaller the value, the closer the shape to the circle. A pipe, especially the water supply and drainage pipe of large diameter, roundness are a set of requirements, that is we often say that the pipeline looks flat, but if the fit of roundness in a certain range when the request should be no problem.
问：常说的5000次冷热水试验是啥意思？
Q: what do you mean by the 5000 hot and cold water test?
答：管材出厂前都必须通过十分严厉的质量检查，其间5000次冷热水是其间十分重要的一部分，首要目的是检查管材和管件在恶劣情况下的运用性能。详细是管材与管件衔接后通冷水15分钟，冷热水交流一次30分钟为一个循环，总共进行5000次，看有无漏水和爆管景象。
A: before leaving the factory must pass a very strict quality inspection, during which the 5000 hot and cold water is a very important part of it, the primary purpose is to check the pipe and pipe fittings in the harsh conditions of the use of performance. After the tube and pipe connection is connected to the cold water for 15 minutes, cold and hot water exchange for a cycle of a total of 30 minutes, a total of 5000 times, to see if there is no leakage and explosion scene.
