問(wèn)：塑料管材和傳統(tǒng)管材的口徑稱謂有何不一樣？
Q: plastic pipe and traditional pipe diameter Title Why not?
答：傳統(tǒng)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英寸等稱號(hào)。新式塑料管材通常不這么稱號(hào)，而是直接用管徑尺度來(lái)斷定，如32、63、300、450等。某些管材也選用內(nèi)外徑一起稱號(hào)，如鋁塑復(fù)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..
問(wèn)： PE給水63級(jí)、80級(jí)、100級(jí)是怎樣區(qū)別的？為何63級(jí)的報(bào)價(jià)最高？
Q: PE water level 63, level 80, level 100 is how to distinguish? Why is the highest price 63?
答：依據(jù)原資料在平等環(huán)境下的耐壓等級(jí)（首要選用靜液壓試驗(yàn)斷定）并圓整后乘以10來(lái)區(qū)分的。例如某種資料的試驗(yàn)壓力為9.99Mpa，通過(guò)圓整后乘以10就為100級(jí)。
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.
等級(jí)越高，通常來(lái)說(shuō)在平等的壓力適用管材上壁厚就越薄，63級(jí)商品因壁厚較厚，資料用量較多，故報(bào)價(jià)較高。
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.
問(wèn)：啥是規(guī)范尺度比？
Q: what is the normative scale?
答：管材的公稱外徑與公稱壁厚的比值。
Answer: the ratio of nominal diameter and nominal wall thickness.
問(wèn)：啥叫管材的圓度？
Q: what is the roundness of the pipe?
答：所謂圓度，即是任一封閉形狀的外接圓與此形狀的面積的差值，和此外接圓面積的比值。數(shù)值越小，闡明此形狀越挨近圓。關(guān)于管材來(lái)說(shuō)，特別是大口徑的給水、排水管，對(duì)圓度都是有必定請(qǐng)求的，也即是咱們常說(shuō)的管道看起來(lái)有些扁，可是如果在必定范圍內(nèi)契合圓度請(qǐng)求時(shí)都應(yīng)該是沒(méi)有問(wèn)題的。
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.
問(wèn)：常說(shuō)的5000次冷熱水試驗(yàn)是啥意思？
Q: what do you mean by the 5000 hot and cold water test?
答：管材出廠前都必須通過(guò)十分嚴(yán)厲的質(zhì)量檢查，其間5000次冷熱水是其間十分重要的一部分，首要目的是檢查管材和管件在惡劣情況下的運(yùn)用性能。詳細(xì)是管材與管件銜接后通冷水15分鐘，冷熱水交流一次30分鐘為一個(gè)循環(huán)，總共進(jìn)行5000次，看有無(wú)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.
