Kev ua kom zoo: tsis muaj cov hlau nplaum rau hauv lub raj PE, thiab cov khoom siv tsis yog cov tshuaj lom, tsis muaj cov txheej txheem, tsis yog cov kabmob cog qoob loo, uas yuav daws tau cov pa phem ntawm cov dej haus hauv lub nroog.
Kev cob qhia zoo heev anticorrosion: nrog rau kev zam ntawm ob peb lub zog oxidants, nws muaj peev xwm tiv thaiv qhov yaig ntawm ntau cov tshuaj media. Tsis muaj hluav taws xob hluav taws xob.
Kev pab lub neej ntev: PE raj xa dej muaj peev xwm siv tau ntev tshaj 50 xyoo ntawm qhov ntsuas thiab ntsuas siab.
Kev ua haujlwm zoo: PE yeeb nkab muaj kev zoo toughness, siab feem ntau thiab hnyav hnyav ncaj qha rau hauv yeeb nkab, uas yuav tsis ua rau cov yeeb nkab kom tawg.
Txhim khu kev sib txuas kev ua haujlwm: lub zog ntawm PE yeeb nkab kub yaj lossis fais fab welding interface yog siab tshaj ntawm cov yeeb nkab lub cev, thiab cov pob qij txha yuav tsis raug kaw vim cov nyom ntawm cov av hauv lub cev los yog lub neej nyob.
Ua zoo siv kev kawm: lub yeeb nkab, kev siv welding yooj yim, tsim kho vaj tsev, tsim nqi tsawg.
Yeeb yam kev sib txuas:
Nws yog txuas nrog ncaj yeeb nkab, ncaj yeeb nkab thiab yeeb nkab phim los ntawm kev siv fais fab fais fab tshwj xeeb. Feem ntau yog siv rau lub tshuab raj 160mm.
Kub yaj taub qab sib sib zog nqus: siv ib qho kev sib khom taub hau kev sib txuas hauv qhov taub, feem ntau tshaj 160 hli yeeb nkab.
Nws tuaj yeem txuas nrog flange, xov ntsia hlau, thiab lwm yam.
Yuav kom tsim kho kev tsim kho thiab ua kom zoo dua kev tsim kho, cov cuab yeej tsim nyog yuav tsum npaj.
