PE管廠家淺析優良PE給水管與低品德PE管的辨認辦法

The identification method of high quality PE water supply pipe and low quality PE pipe

PE管是聚乙烯制管,多爲黑色管道,僅僅從外不雅上去辨認質量的利害是比擬艱苦的。甚麽樣的PE管是質量好的,甚麽樣的管材又是低品德的?若何分辯PE管的利害呢?劣質管是否是晦氣于飲水的平安呢?壹路看看雨洪實業爲人人總結的內容吧;

PE pipe is made of polyethylene, mostly black. It is difficult to identify the quality only from the appearance. What kind of PE pipe is of good quality and what kind of pipe is of low quality? How to distinguish the quality of PE pipe? Is the poor pipe not conducive to the safety of drinking water? Let's take a look at what Yuhong industry summarized for you;

隨著對PE管需求量的賡續增長,市場上的回料PE管也多了起來。這類管材在耐腐上、韌性強度和應用壽命上大大的較低了。PE管多用于給水管,統稱爲pe給水管,關於一些重點水利工程或許市政給水工程應用的pe給水管都爲地下埋管,一旦應用了低品德pe管,將給人們將來的臨盆生涯帶來嚴重隱患,是以,學會辨認PE管的質量長短常主要的。

With the increasing demand for PE pipes, there are more PE pipes in the market. This kind of pipe is greatly lower in corrosion resistance, toughness strength and service life. PE pipes are mostly used for water supply pipes, collectively referred to as PE water supply pipes. For some key water conservancy projects or municipal water supply projects, PE water supply pipes are buried underground pipes. Once low-quality PE pipes are used, it will bring great hidden danger to people's future production and life. Therefore, it is very important to learn to identify the quality of PE pipes.

(1)PE管外不雅:

(1) appearance of PE pipe:

l2-141125133J0-50_255_185.jpg

優良管外不雅上滑膩,無氣泡、凹陷、雜質等缺點。

The high-quality tube is smooth in appearance and free of bubble, depression, impurity and other defects.

低品德:表裏外面粗拙、有氣泡、有麻點,有顯著凹陷。

Low quality: rough internal and external surfaces, with bubbles, pockmarks and obvious depressions.

(2)管道焊口

(2) pipe welded junction

焊口也叫焊接接頭,及格的焊接接頭應滑膩和對稱,優良的PE管焊口:翻邊的全部圓周管道,不得低于低翻邊深度和交織邊的寬度在pe管焊口焊縫鄰近的翻邊不得跨越管道的10%的壁厚,且翻邊平整滑膩。

Welded joint is also called welded joint. Qualified welded joint shall be smooth and symmetrical. High quality PE pipe welded joint: the whole circumference pipe with flanging shall not be less than the minimum flanging depth and the width of staggered edge. The flanging near the weld joint of PE pipe shall not be more than 10% of the wall thickness of the pipe, and the flanging shall be flat and smooth.

低品德PE管:翻邊後,外面會發生大批的孔洞,翻邊短。

Low quality PE pipe: after flanging, there will be a lot of holes on the surface, and flanging is short.

(3)聞滋味

(3) smell

優良PE管:沒有氣息。

High quality PE pipe: no smell.

低品德:刺鼻的氣息。

Low quality: pungent smell.

(4)PE管的銑削條帶

(4) milling strip of PE pipe

優良PE管:亮油,平整,重復折諜不容易斷裂。

High quality PE pipe: bright oil, flat, repeatedly folded and not easy to break.

低品德:色彩較深,輕易折斷。

Low quality: darker color, easy to break.

(5)斷裂伸長率(參考PE管磨練申報)

(5) elongation at break (refer to PE pipe inspection report)

優良管:斷裂伸長率是拉伸時試樣的長度與原長度之比。優良的PE管拉伸至3.5次賡續裂,斷裂伸長率越高,産品的柔韌性和機能越好。

High quality pipe: the elongation at break is the ratio of the length of the sample to the original length when drawing. High quality PE pipe is not broken 3.5 times. The higher the elongation at break, the better the flexibility and performance of the product.

低品德:易斷,韌性差。

Low quality: easy to break, poor toughness.

(6)熄滅視察PE管火焰

(6) combustion observation PE tube flame

PE管爲聚乙烯成品,優良的PE管熄滅後火焰呈藍色。

PE pipe is made of polyethylene. The flame of high-quality PE pipe is blue after combustion.

低品德:熄滅後發生大批的黑煙,多是參雜著大批的收受接管料。

Low quality: a large amount of black smoke is produced after combustion, which may be mixed with a large number of recycled materials.
