Amalunga ensimbi engagqwaliikakhulukazi asetshenziselwa ukuxhuma amapayipi ahlukahlukene abe amapayipi.Ngokuthuthuka okusheshayo kokwakhiwa kwezomnotho kwezihlanganisi zensimbi engagqwali, izinsimbi zensimbi ezingenasici zisetshenziswe kabanzi.Ngokuhlaziywa kokumelana nokugqwala kwesendlalelo se-passivation ebusweni bensimbi engagqwali, kuhlanganiswe nokusetshenziswa kobuchwepheshe obuphambili bokukhiqiza kanye nemishini, ukukhiqizwa kuhlangabezana nezidingo zokukhiqiza nokuphila.Izinto ezisezingeni eliphezulu zensimbi engagqwali zigcwalisa igebe lasekhaya.
Ukufakwa kwensimbi engagqwaliziwuhlobo lwamashubhu.Yenziwe ngensimbi engagqwali, ngakho ibizwa nge-stainless steel pipe fittings.Kubandakanya: indololwane yensimbi engagqwali, insimbi engagqwali, isiphambano sensimbi engagqwali, isinciphisi sensimbi engagqwali, ikepisi lensimbi engagqwali, njll. Amapayipi angahlukaniswa abe uhlobo lwesokhethi okufakwayo kwepayipi lensimbi engagqwali, okufakwayo okucushwe ngensimbi engagqwali, okufakwayo kwepayipi lohlobo lwe-flange futhi ashiselwe. ukufakwa kwepayipi lensimbi engagqwali ngokwendlela yokuxhuma.Izindololwane zensimbi engagqwali zisetshenziswa ekujikeni kwepayipi;ama-flange asetshenziselwa ukuxhuma ingxenye yepayipi futhi axhume ekupheleni kwepayipi.Ukuhlangana kwamapayipi amathathu kusebenzisa ipayipi lensimbi engagqwali;ukuhlangana kwamapayipi amane amukela ipayipi lensimbi engagqwali;ipayipi yokunciphisa insimbi engenasici isetshenziselwa ukuxhuma amapayipi amabili ububanzi obuhlukene.
Amajoyinti ensimbi engagqwali asetshenziswe kabanzi emikhakheni eyahlukene yokwakha umnotho kazwelonke, njengemithi, ukudla, ubhiya, amanzi okuphuza, i-biotechnology, imboni yamakhemikhali, ukuhlanzwa komoya, izindiza, imboni yenuzi, njll. Kunomthelela omkhulu ekukhiqizeni abantu futhi ukuphila.
Ukufakwa kwensimbi engagqwali kunezinzuzo ezinkulu mayelana nokumelana nokugqwala.Izimboni ze-petrochemical, i-aerospace, namandla enuzi zinconywa kakhulu ukusebenzisa insimbi engagqwali.
1. Kungani insimbi engagqwali ingagqwali?
Ingqikithi yensimbi engagqwali engagqwali ukuthi uma insimbi engagqwali ichayeka kugesi, ifilimu ye-passivation yakheka ngokushesha phezulu, ngaleyo ndlela ivimbele ukuqhubekela phambili kwe-oxidation.Le filimu ye-passivation inokumelana ne-asidi eqinile.Ukumelana nokugqwala.Kodwa futhi iyagqwala ezindaweni ezithile ezikhethekile, njengalezi: indawo enomswakama kanye nenkungu yayo yasolwandle enosawoti.
2. Cishe 304, 316, 316L
I-304 insimbi engagqwali iyinto evamile eyaziwa futhi embonini njengensimbi engagqwali engu-18/8.Inezici zokusebenza kahle kokucubungula kanye nokuqina okuqinile, futhi ngokuvamile ifaneleka ezimbonini nezinkambu zokuhlobisa ifenisha.
Okuqukethwe kwekhabhoni okungu-316 kukhulu kuno-0.08%, futhi amandla angu-316 ngokuvamile aphakeme kancane kunalawo ezinto ezingu-316L.Ngokuvamile, izinto ezingu-316 zisetshenziselwa amalunga e-ferrule.
I-316L inokuqukethwe kwekhabhoni enkulu okungu-0.03% futhi inokumelana nokugqwala okungcono.Kunconywa ukusebenzisa i-316L ezintweni zomkhiqizo okumele zishiselwe.
3. Ukubukeka
Uma kuqhathaniswa namajoyinti e-carbon steel, amalunga ensimbi engagqwali angagaywa futhi apholishwe ukuze kubonakale ukugqama, ukucwebezela, kodwa i-carbon steel idinga ukugcotshwa ngokushesha nge-coating ecacile noma ngopende ngemva kokupholishwa, ngaphandle kwalokho i-carbon steel izogcina ilahlekelwe ukucwebezela kwayo futhi ekugcineni igqwale. , Insimbi engagqwali ayidingekile.
