PE pombi akati wandei akakosha zvivakwa

1.PE pombi ngura kuramba maitiro?

Polyethylene chinhu chine inert chinogona kumira nekuora kweakasiyana makemikari media.Hapana electrochemical corrosion, hapana anti-corrosion layer.

2. Kusina-kudonha maitiro ePE tube?

Polyethylene pombikunyanya inotora welding yekubatanidza (inopisa fusion yekubatanidza kana yemagetsi fusion yekubatanidza), iyo inonyanya kuve nechokwadi chekuzivikanwa kweiyo interface zvinhu, chimiro uye pombi muviri, uye inoona kubatanidzwa kwejoint uye pombi.Kuedza kunoratidza kuti kusimba kwesimba uye kuputika simba kweiyo interface yakakwira kupfuura iyo yemuviri wepombi, uye hapana dambudziko rekudonha kana richienzaniswa nemajoini erabha kana mamwe majoini emuchina.

3.PE pombi yakakwirira kuomarara maitiro?

Polyethylene pombi imhando yekusimba kwepombi, kureba kwayo panguva yekuzorora kazhinji inodarika 500%, kugona kuchinjika kune isina kuenzana kugadzikana kwepombi base kwakasimba kwazvo.Iyo zvakare imhando yepombi ine yakanakisa anti-seismic performance.Muna 1995 Kobe kudengenyeka kuJapan, polyethylene gasi pombi uye mvura pombi pombi ndiyo pombi hurongwa akaponeswa.Nokudaro, Japan mushure mekudengenyeka kwenyika inokurudzira zvakasimba kushandiswa kwe PE pombi mumunda wegesi.

4.PE chubhu ine yakanakisa kuchinjika maitiro?

Iko kuchinjika kwe polyethylene inobvumira polyethylene mapaipi kuti adzorerwe uye apiwe muhurefu hwakareba pasina kudiwa kweakasiyana majoini ekubatanidza.Nekuvaka kusina trenchless, kutungamira kwepombi ye polyethylene inogona kuchinjwa nyore nyore maererano nezvinodiwa nenzira yekuvaka, uye saizi yepakutanga uye chiyero chinogona kudzorerwa mushure mekuvaka.

5. Nzira yekunzwisisa sei maitiro ePE chubhu nekudzivisa kwakanaka kune zvikweshwa?

Zvisungo zvinokonzeresa kushushikana mupfungwa muzvinyorwa, zvichiita kuti kukundikana kwepombi.Kana tekinoroji isina trench ikashandiswa, kukwenya kunonyanya kunetsa kudzivirira, ingave pombi itsva yakaiswa kana pombi yekare inotsiviwa.Mumakore achangopfuura, zvakaratidzwa kuti PE80 giredhi polyethylene pombi ine nani kuramba kunonotsa mutswe kukura uye kukwenya kuramba, uye PE100 polyethylene pombi ine nani mukwenya kuramba.Naizvozvo, pombi ye polyethylene inoshandiswa zvakanyanya mukuvaka tekinoroji isina trenchless.

6. PE pombi ine hunhu hwakanaka hwekukurumidza mutswe kutapurira kuramba.

Kutsemuka nekukurumidza kwepombi imhando yetsaona netsaona.Kutsemuka kunowedzera nekukurumidza pane imwe sipidhi, zvichikonzera kuputika kwemakumi emamita kana kunyange zviuru zvemamita epombi ipapo ipapo, uye mhedzisiro inokonzeresa injodzi.Kare kuma1950, pakanga paine tsaona dzakati wandei dzinoputika mupombi yegasi yeUnited States.Kukurumidza kuputika kwepolyethylene gasi pombi haina kuwanikwa mukuita.Mumakore achangopfuura, tsvakiridzo yakawanda yakaitwa pakukurumidza kuputika kwepombi munyika.Mhedzisiro yacho inoratidza kuti kuramba kwepombi yepolyethylene kuparadzira kupararira kuri pakati pezvakanakisa.
