Ulayini wokukhiqiza amapayipi kathayela wepulasitiki kabili odongeni

Ipayipi likathayela odongeni oluphindwe kabili le-HDPE lingelepayipi eliguquguqukayo.Ukusebenza kwayo kungokulandelayo:

Ikhono eliqinile lokumelana nokucindezela kwangaphandle
Udonga lwangaphandle luyindandatho ye-corrugated structure, ethuthukisa kakhulu ukuqina kwendandatho yepayipi, ngaleyo ndlela ithuthukise ukumelana kwepayipi ekulayisheni umhlabathi.Kulokhu kusebenza, imibhobho ye-HDPE enodonga oluphindwe kabili inezinzuzo ezisobala uma iqhathaniswa namanye amapayipi.

Izindleko zephrojekthi eziphansi
Ngaphansi kwesimo somthwalo ofanayo, i-HDPE double wall bellows idinga kuphela udonga oluncane ukuze luhlangabezane nezidingo.Ngakho-ke, uma kuqhathaniswa neshubhu yodonga oluqinile olunemininingwane efanayo, ingonga cishe uhhafu wezinto ezingavuthiwe, ngakho-ke izindleko ze-HDPE ezivuthela ngodonga oluphindwe kabili nazo ziphansi.Lesi esinye isici esivelele se-tube.

Ukwakha kulula
Ngenxa yokuthi izimbongolo ze-HDPE ezinodonga oluphindwe kabili zinesisindo esincane futhi zilula ekuphatheni nasekuxhumekeni, ukwakhiwa kuyashesha futhi nokugcinwa kulula.Esikhathini sokwakha qinisa futhi

Endabeni yezimo ezimbi, inzuzo yayo isobala kakhulu.
I-coefficient encane yokungqubuzana nokugeleza okukhulu

I-HDPE evuthela odongeni ephindwe kabili eyenziwe nge-HDPE ingadlula izinga lokugeleza elikhulu kunamanye amapayipi anezinga elifanayo.Ngamanye amazwi, izidingo zokugeleza ezifanayo, zingasebenzisa i-HDPE enezingqimba eziphindwe kabili zodonga.

Izinga lokushisa eliphansi kanye nokumelana nomthelela
Izinga lokushisa le-embrittlement le-HDPE-double-wall bellows ngu-70℃.Izimo ezivamile zokushisa eziphansi (ngaphezulu -30 ℃) azidingi ukuthatha izinyathelo ezikhethekile zokuzivikela lapho ukwakhiwa, ukwakhiwa kwasebusika kulungele, futhi, i-HDPE double wall bellows inokumelana nomthelela omuhle.

Ukuzinza okuhle kwamakhemikhali
Ngenxa yokuthi ama-molecule e-HDPE awanayo i-polarity, anokuqina okuhle kwamakhemikhali.Ngaphandle kwama-oxidants ambalwa aqinile, imidiya eminingi yamakhemikhali ayikwazi ukuyibhubhisa.Umhlabathi, ugesi, i-asidi kanye nezinto ze-alkali endaweni yokusetshenziswa okuvamile ngeke kubangele ukulimala kwepayipi, awekho amagciwane, akukho ukukala, futhi indawo yawo yokujikeleza ngeke yehle ngokwanda kwesikhathi sokusebenza.

Impilo ende yesevisi
Impilo yesevisi ye-HDPE's double-wall bellows ingafinyelela ngaphezu kweminyaka engama-50 ngaphandle kokukhanya kwelanga.

Ukumelana nokugqoka okuhle kakhulu
IJalimane isebenzise izivivinyo zokufakazela ukuthi ukumelana nokugqokwa kwe-HDPE kuphakeme ngokuphindwe kaningana kunokwepayipi lensimbi.

Ukuphambuka okufanele
Ubude obuthile bepayipi likathayela elinodonga oluphindwe kabili lwe-HDPE bungathinteka kancane, bungathintwa izinga elithile lokuhlala okungalingani phansi, bungabekwa ngokuqondile emseleni ongaqondile njalo njalo.
