Ekukhiqizeni izimboni, ubuqotho nokuqina kwamapayipi ensimbi kubaluleke kakhulu. Enye yezindlela eziphumelela kakhulu zokuqinisekisa ukuthi la mapayipi amelana novivinyo lwesikhathi kanye nezinselele zemvelo ngokusebenzisa ubuchwepheshe bokumboza obuphambili. Izembatho ze-Fusion-bonded epoxy (FBE) kanye namalayini kuyizinketho eziphezulu zokuvikela ukugqwala. I-Cangzhou Spiral Steel Pipe Group Co., Ltd., umkhiqizi ohamba phambili enekomkhulu e-Cangzhou, eSifundazweni sase-Hebei, ibihamba phambili kulobu buchwepheshe kusukela yasungulwa ngo-1993.
Namuhla, ngamapayipi kawoyela agqitshwe ngokujulile ngaphansi komhlaba kanye namapayipi ahamba ngaphansi kolwandle amelana nokuguguleka kukasawoti, ubuchwepheshe bokulwa nokugqwalaI-Fbe Coating And Liningihlobene ngokuqondile nokuphepha nokuphila kwemithambo yamandla. Njengebhizinisi elihamba phambili emkhakheni wokukhiqiza amapayipi ensimbi avunguzayo e-China, i-Cangzhou Spiral Steel Pipe Group Co., Ltd. inikeza amakhasimende omhlaba izixazululo zepayipi lensimbi elilwa nokugqwala ngempilo yesevisi yeminyaka engaphezu kwengu-20 ngokwethembela kubuchwepheshe bayo bokumboza be-fusible epoxy powder (FBE) obakhiwe ngokuzimela. Isebenze ngaphezu kwe-3,000 imisebenzi emikhulu yasekhaya neyangaphandle isiyonke.
I-FBE Coating: Isikhali sobuchwepheshe esinweba isikhathi sokuphila samapayipi ensimbi ezindaweni eziyingozi kakhulu
Isimiso sobuchwepheshe
I-epoxy powder inamathela ngokulinganayo ebusweni bepayipi lensimbi ngokufafazwa kwe-electrostatic, bese kwakheka ungqimba oluqinile lokuvikela ngemuva kokuphulukiswa kwezinga lokushisa eliphezulu, kuzuzwe:
Ukunamathela okuphezulu: Amandla okubopha phakathi kweFbe Coating Pipefuthi i-substrate yepayipi lensimbi ingu-≥70MPa (iphindwe kathathu izinga lemboni)
Ukuvikelwa kwemvelo okugcwele: Ukumelana ne-asidi, i-alkali, amanzi olwandle nokuguguleka kwe-microbial, ilungele izimo zokusebenza ezisukela ku -30 ℃ kuya ku-110 ℃
Okuluhlaza futhi kunobungani kwemvelo: 0 ukukhishwa kwe-VOC, kuqinisekiswe izindinganiso zamazwe ngamazwe ISO 21809-2
Izixazululo ezisebenzayo zokumboza zibalulekile, ikakhulukazi ezimbonini lapho amapayipi ensimbi echayeka ezimweni ezinzima zemvelo. Izingubo ze-polyethylene ezijwayelekile ezisetshenziswa efekthri ezinezendlalelo ezintathu, kanye nezigqoko ze-polyethylene ezinezingqimba ezilodwa noma ezinezingqimba eziningi, zenzelwe ukuhlinzeka ngokuvikela ukugqwala okuqinile kwamapayipi ensimbi nokufakwa. Izembatho ze-FBE zidume ngokunamathela kwazo okuhle kakhulu kanye nokumelana nokugqwala. Inqubo ihilela ukusebenzisa ungqimba lwempushana ye-epoxy ebusweni bepayipi lensimbi bese ulishisa ukuze kwakhiwe isibopho esiqinile. Le ndlela ayivikeli nje kuphela insimbi ekugqwaleni kodwa futhi ithuthukisa izici zayo eziwumshini. Ekugcineni, amapayipi ayakwazi ukumelana nezimo ezimbi kakhulu, ukuqinisekisa impilo ende yesevisi nokunciphisa izindleko zokulondoloza.
I-Cangzhou Spiral Steel Pipe Group Co., Ltd. isebenzisa izinqubo zokumboza ezisezingeni eliphezulu ukuze kuqinisekiswe ukuthi umkhiqizo ngamunye uhlangabezana nezindinganiso eziphakeme kakhulu zemboni. Ukuzibophezela kwenkampani kwikhwalithi kubonakala ekuhloleni kwayo okuqinile kanye nezinyathelo zokulawula ikhwalithi, iqinisekisa ukuthi wonke amapayipi amboziwe asebenza kahle ezindaweni ezidinga kakhulu.
Ngamafuphi, indima ye-FBE yokumboza kanye ne-linings ekuvikelweni kwamapayipi ensimbi ayikwazi ukubukelwa phansi. Ngolwazi nobuchwepheshe obuthuthukisiwe be-Cangzhou Spiral Steel Pipe Group Co., Ltd., izimboni emikhakheni ehlukahlukene zingaqinisekiswa ukuthi amapayipi azo azovikeleka ngendlela efanele ekulimaleni nasekulinyazweni kwemvelo. Njengoba inkampani iqhubeka nokusungula nokwandisa umugqa womkhiqizo wayo, sihlala singabalingani abathembekile kumabhizinisi afuna izixazululo ezinokwethenjelwa nezihlala isikhathi eside zamapayipi ensimbi. Kungakhathaliseki ukuthi usembonini kawoyela negesi, ezokwakha, nanoma yimuphi omunye umkhakha othembele epayipini lensimbi, i-Cangzhou Spiral Steel Pipe Group Co., Ltd. iyisinqumo sakho sokuqala sepayipi lensimbi elinekhwalithi ephezulu, eliqinile.
