Ibhetshi yeejoyinti zerabha ezijijekileyo ze-DN200 zenziwe kwaye zilungele ukuthunyelwa. Olu luhlu lwemveliso lunikezelwa kakhulu kwiiprojekthi zobunjineli zaphesheya kwezilwandle kuquka ukunikezelwa kwamanzi kunye nokuhambisa amanzi, ishishini leekhemikhali, izikhululo zamandla, i-HVAC kunye nonyango lwamanzi olwandle. Inani elikhulayo labathengisi be-EPC bamazwe ngamazwe kunye nabathengi bemibhobho badla ngokukhetha iijoyinti zerabha ezijijekileyo, ikakhulu ngenxa yokuba ezi zihlanganisi eziguquguqukayo zisombulula ngempumelelo iindawo ezibuhlungu ezingapheliyo ngexesha lokusebenza kwemibhobho ixesha elide.

Iinkqubo zemibhobho zinoxinzelelo lokuhamba olubangelwa kukutshintsha kobushushu, ukungcangcazela koomatshini okuvela kwizixhobo ezijikelezayo, ukungalungelelani kofakelo kunye nokumiswa kwesiseko. Izixhobo zemibhobho yesinyithi eziqinileyo eziqhelekileyo zisengozini yokuqhekeka kwe-weld kunye nokuvuza kweflange phantsi koxinzelelo oluphindaphindeneyo. Ukungcangcazela okuqhubekayo okubangelwa ziipompo zamanzi kunye nee-blower kudlulisa ingxolo kwizakhiwo zemibhobho, okukhokelela ekonakaleni kokudinwa kweevalvu, izixhobo kunye nezixhobo eziphambili emva kokusebenza ixesha elide. Amalungu okwandiswa kwerabha ajikelezileyo ayilwe ngokukodwa ukuze oyise yonke le mingeni.

Olu hlobo lwerabha luneempawu zobugcisa ezibalaseleyo. Umzimba werabha uhlanganiswe ngokupheleleyo ngelaphu eliqinisiweyo elinamaleya amaninzi kunye ne-elastomer esebenza kakuhle, ehambelana neeflanges zentsimbi yekhabhoni ezintantayo. Ifunxa intshukumo ekhokelela kwicala elinye kubandakanya ukwandiswa kunye nokuqiniswa kwe-axial, i-offset esecaleni kunye nokuphambuka kwe-angular. Ngenxa yesakhiwo sayo se-elastic, i-expansion joint iyayisusa ngokufanelekileyo i-mechanical vibration, inciphisa ingxolo yepayipi kwaye ithintele ukudluliselwa kwe-vibration kuyo yonke inethiwekhi yepayipi. Izinto ezininzi ze-elastomer ezifana ne-EPDM, i-NBR kunye nerabha yendalo zikhethwa ukuba zifake amanzi acocekileyo, amanzi amdaka, i-acid ebuthathaka kunye nolwelo lwe-alkali, ioyile kunye nezinye iindlela, zibonelela ngokusebenza okubalaseleyo kokulwa nokwaluphala kunye nokulwa nokugqwala.

Xa kuthelekiswa namalungu okwandisa esinyithi, amalungu okwandisa erabha athambileyo anokufakelwa okulula ngaphandle kweenkqubo ezinzima zokolula kwangaphambili, anyamezela ukungalungelelani okuncinci ngexesha lokuhlanganiswa kwindawo. Agcina ukusebenza okuzinzileyo kokutywina kunye nomthamo ophezulu wokungcangcazela kunye nokunciphisa ingxolo. Isakhiwo esilula sinciphisa iindleko zokuthutha kwaye sinciphisa kakhulu iindleko zokulungisa eziqhelekileyo kubasebenzisi bokugqibela. I-DN200 (8 intshi) bukhulu obuqhelekileyo obusetyenziswa kakhulu kwizikhululo zokumpompa ezinkulu neziphakathi, iipayipi zamanzi ezijikelezayo kunye neepayipi zenkqubo. Kukho ubungakanani obuqhelekileyo obuqala kwi-DN50 ukuya kwi-DN1200, kunye neeklasi zoxinzelelo ze-PN10 kunye ne-PN16 ukwanelisa iimfuno ezahlukeneyo zeprojekthi.

Iijoyinti zethu zokwandisa irabha zisetyenziswa kakhulu kubonelelo lwamanzi lukamasipala waphesheya, kwizityalo zonyango lwamanzi amdaka, kwiinkqubo zomoya opholileyo ze-HVAC, kwiipayipi zokujikeleza i-petrochemical, kwiipayipi zaselwandle nakwiisekethe zokupholisa izityalo zamandla. Ukufakwa ngokufanelekileyo kweejoyinti zokwandisa irabha kukhulula uxinzelelo lobushushu nolwemishini ngaphakathi kweepayipi, kukhusela iimpompo kunye neevalvu, kunciphisa ukusilela kokuvuza kwaye kwandisa ubomi benkonzo yenkqubo yonke yepayipi. Inceda iiprojekthi zaphesheya ukunciphisa iindleko zokusebenza kwexesha elide kunye nokugcinwa, okwenza ijoyinti yokwandisa irabha edibeneyo ibe yinxalenye ebalulekileyo kubunjineli bokuthuthwa kolwelo lwanamhlanje.
