Steel Tubes In The Chemical & Petrochemical Industry

Inqubo yokufaka amapayipi
Ezitshalweni zamakhemikhali kanye ne-petrochemical, amashubhu ensimbi akha umgogodla wezinqubo zamapayipi ezithwala izinto zokusetshenziswa, imikhiqizo ephakathi, namakhemikhali aphelile. Lawa masistimu amapayipi kufanele aphathe uketshezi oluhlukahlukene, okuhlanganisa ama-acids abolayo, izinyibilikisi, ama-hydrocarbon, namagesi ngaphansi kwengcindezi nezimo zokushisa ezihlukene. Insimbi ye-carbon steel, insimbi engagqwali, namashubhu ensimbi ye-alloy akhethwa ngokusekelwe ekwakhekeni kwamakhemikhali nezimo zokusebenza ukuze kuqinisekiswe ukuqina nokumelana nokugqwala, ukuguguleka, kanye nengcindezi yokushisa.

Izishintshi Zokushisa kanye nama-Boilers
Amashubhu ensimbi asetshenziswa kabanzi kuma-heaters kanye nama-boilers, imishini ebalulekile yokulawula izinga lokushisa ezinkambisweni zamakhemikhali. Izishintshisi zokushisa zidlulisa ukushisa phakathi koketshezi olubili ngaphandle kokuluxuba, ngokuvamile oluhlanganisa izinto ezibolayo noma ezinezinga lokushisa eliphezulu. Amashubhu kufanele abonise ukuhamba kahle kwe-thermal, ukumelana nokugqwala, namandla okusebenza ukuze amelane nokuhamba ngebhayisikili okushisayo nezimo zokucindezela okuphezulu. Amashubhu ensimbi engagqwali kanye nengxubevange ayakhethwa ngenxa yekhono lawo lokumelana nokukala, ukonakala, nokugqwala.

Imikhumbi Yengcindezi Nezimpendulo
Imikhumbi yokucindezela kanye nama-reactor amakhemikhali yizingxenye ezibalulekile lapho amashubhu ensimbi asetshenziselwa khona ukwakha amashubhu angaphakathi, amakhoyili, noma amabhantshi enza kube lula ukusabela kwamakhemikhali ngaphansi kwengcindezi elawulwayo nezinga lokushisa. Amashubhu ensimbi kufanele ahlangabezane nezindinganiso eziqinile zokuvimbela ukuvuza, amelane nezingcindezi zangaphakathi, futhi amelane nokuhlaselwa kwamakhemikhali. Izinsimbi ze-alloy ezisezingeni eliphezulu nezinsimbi ezingenasici zivame ukusetshenziswa, ngokuvamile ngokwelashwa okukhethekile kwendawo noma amalayini ukuze kuthuthukiswe ukumelana nokugqwala.

Izinhlelo Zokugcina Nokudlulisa
Amashubhu ensimbi abalulekile emathangeni okugcina kanye namapayipi okudlulisa aphatha amakhemikhali ahlukahlukene kanye nemikhiqizo ye-petrochemical. Lawa mashubhu axhuma amathangi kumayunithi okucubungula kanye namanethiwekhi okusabalalisa, adinga izixazululo zokungavuzi nezimelana nokugqwala. Amashubhu kufanele agcine ubuqotho besakhiwo ngaphansi kwengcindezi eguquguqukayo kanye nokuchayeka kumakhemikhali anolaka, ngokuvamile okudingeka ukuthi kusetshenziswe ama-alloy amelana nokugqwala noma izimbotshana ezivikelayo.

Izicelo ze-Cryogenic kanye Nezinga Lokushisa Eliphezulu
Izinqubo ezithile zamakhemikhali neze-petrochemical zibandakanya amazinga okushisa aphansi kakhulu noma aphezulu. Amashubhu ensimbi asetshenziswa ezinhlelweni ze-cryogenic, ezifana nokubamba nokugcinwa kwegesi yemvelo ewuketshezi (LNG), kufanele agcine ukuqina emazingeni okushisa aphansi kakhulu ukuze avimbele ukwehluleka ukubola. Ngokuphambene, amashubhu asetshenziswa eziko lokushisa eliphezulu noma ama-reactors kumele amelane nokunwebeka okushisayo kanye ne-oxidation. Izinsimbi ezikhethekile ezingenasici kanye nama-alloys asekelwe ku-nickel ngokuvamile asetshenziswa ukuhlangabezana nalezi zinselele.

Izinhlelo Zokuphepha Nezemvelo
Amashubhu ensimbi nawo adlala indima ekuphepheni nasezinhlelweni zokulawula imvelo ngaphakathi kwezitshalo zamakhemikhali. Asetshenziswa emigqeni yokuvuleka, amasistimu okukhipha umoya, nasezikhuhleni ezidizayinelwe ukuphatha ngokuphephile amagesi noma ukukhishwa kwekhabhoni. Lezi zinhlelo zokusebenza zidinga amashubhu ensimbi akwazi ukumelana nokugqwala okuvela kumagesi ane-asidi noma anobuthi futhi amelane nokwanda kokucindezela, okuqinisekisa ukusebenza okuphephile kwezitshalo nokuthobela indawo ezungezile.

Amashubhu ensimbi abalulekile embonini yamakhemikhali neye-petrochemical, esekela izinqubo eziyinkimbinkimbi ezidinga izinto eziqinile, ezithembekile, nezimelana nokugqwala. Ukuguquguquka kwazo ekuphatheni imidiya yamakhemikhali ehlukahlukene, amazinga okushisa adlulele nezingcindezi kuzenza zibaluleke kakhulu ekusebenzeni okuphephile nangempumelelo kwezitshalo zamakhemikhali zanamuhla. Intuthuko kwezensimbi nokukhiqiza iyaqhubeka nokuthuthukisa ukusebenza kwamashubhu ensimbi, okwenza imboni ihlangabezane nezindinganiso eziqinile zokuphepha kanye nemvelo.
