I-Dubai Torch torch Fire Cast Amapayipi ensimbi okuvikela umlilo

Umlilo weTorch Tower waseDubai

Agasti 4, 2017, umlilo omkhulu udabule esinye sezakhiwo ezinkulu zokuhlala emhlabeni, iTorch Tower eDubai. Amalangabi adubule ohlangothini lwe-skyscraper, athumela imfucumfucu iwa isuka kusakhiwo esingu-337m (1,106 ft). Abantu bebeklabalasa ngesikhathi bevuka ilangabi lomlilo ebusuku ngaphambi kokuthi babaleke. Ngenhlanhla, i-Dubai Civil Defense ikhiphe ngempumelelo umbhoshongo wethoshi futhi yalawula umlilo, abekho abashonile kodwa ukulahleka kwezomnotho okuqondile kwamashumi ezigidi zamaRandi. I-Dubai Civil Defence ithe ibhodi lesakhiwo elivuthayo langaphandle elifaka udonga ukwenza umlilo weTorch usakazeke ngokushesha, ukuphepha kwempahla yokwakha kufanelekile ukucabangisisa.

Ukufunda Okunwetshiwe
Uma kuqhathaniswa nepayipi le-PVC, kungani ukhetha i-DS cast iron pipe drainage system? – Ukuvikelwa komlilo

I-Dinsen ibambe iqhaza kakhulu ku-EN877 DS brand epoxy resin cast iron drain pipe kanye nezinsiza ezisetshenziswa ezindaweni eziningi zokudonsa amanzi ebhilidini, indle nezinhlelo zokungenisa umoya. Uma kuqhathaniswa namapayipi epulasitiki aletha izinkinga zokuphepha komsindo nezinkinga zomlilo, amapayipi ensimbi ensimbi anezici ezinhle kakhulu ezicacile: amandla aphezulu, ukumelana nokuhuzuka, ukugqwala kanye nomthelela, ukuvikela umlilo nokungewona ubuthi, kuhlangabezana nezidingo zokuphepha komlilo kanye nezidingo zokuvikela imvelo, akukho msindo, akukho deformation, ukuphila isikhathi eside, ukufakwa kalula nokugcinwa izinzuzo.

Nakhu ukugxila ekuphikiseni umlilo kwepayipi lensimbi ye-DS cast. Amapayipi ensimbi e-DS cast kanye nezinsiza aqukethe insimbi empunga ene-lamellar graphite, izivivinyo kanye nemininingwane yobuchwepheshe kuchazwa ukuthi ihambisane ne-EN877. I-Annex F ye-EN877 ithi imikhiqizo ye-Cast iron ngokuhambisana naleli zinga lase-Europe ayinakushi futhi ayishi. Lapho bechayeka emlilweni bazogcina izici zabo zokusebenza nobuqotho amahora ambalwa, okungukuthi izindonga zabo ziyohlala zingenakunqotshwa amalangabi namagesi futhi ngeke kube nokuphuka, ukuwa noma ukuguqulwa okuphawulekayo. Ubuqotho bokuxhuma ngezindonga nophahla kugcinwa.

I-DS cast iron ayishi, ayiwodli umlilo, futhi ayikhiphi amagesi noma intuthu enesibopho sokubambezela izicishamlilo noma kulimaze ezinye izinto zokusebenza. Uma kwenzeka umlilo kukhombisa izinzuzo ezimbili ezisobala:

1 Ukumelana nomlilo – ukuvikela ukubhebhetheka komlilo
Amasistimu wokudonsa amanzi adlula ezakhiweni eziklanyelwe ukumelana nomlilo, akufanele anikeze ukuphulwa okuvulekile. Isikhathi esithile, esicaciswe emithethweni esebenzayo, akufanele bavumele ukudlula komlilo, intuthu, ukushisa noma imikhiqizo evuthayo isuka kwenye ingxenye iye kwenye. Ngenkathi kumapulasitiki, umthetho wokumisa umlilo uhlanganisa 'ukuxhuma imbobo', izinto zepulasitiki ezizwela kakhulu ukushisa ngeke zimelane nomlilo, ngeke zihlale zisendaweni, ngisho nalapho kunomlilo oqukethwe.

2 Ukugwema ukulimala kwentuthu enobuthi
Ipayipi lepulasitiki lapho livutha lizokhiqiza imfucumfucu enobuthi eningi, esakazeka kalula. Nakuba ipayipi le-cast iron drainage lingashi, ukuze lingakhiqizi intuthu enobuthi. Futhi kuzoba nentuthu encane uma efakwe ama-couplings ama-gaskets erabha ambozwe ngokuphelele ngamakholomu ensimbi engagqwali (isb. i-DS Rapid coupling noma i-CH/CV/CE coupling), isistimu yamapayipi ihlala ivaliwe uma kuba nomlilo. Noma iyiphi intuthu ekhiqizwe ukushisa kwento engaphakathi ihlala epayipini bese ikhishwa ngezimbobo zokungenisa umoya phezu kophahla.

Ulwazi olwengeziwe, wamukelekile ukuxhumana nathi.
