Lokhu kubaluleke kakhulu ezibophweni zensimbi engagqwali ngoba ukuqinisa ngokweqile kungalimaza inqwaba, kuyilapho ukuqinisa okunganele kungaholela ekukhululekeni ngaphansi kokudlidliza. Uma iphrojekthi idinga nokumelana nokugqwala, uhlelo lwensimbi engagqwali luvame ukukhetha kunezibopho ze-polymer ezindaweni zokushisa okuphezulu noma zokuvezwa ngaphandle.

Abathengi abaningi kufanele futhi bacabange ngokwezindleko ezifakiwe. Indlela eshibhile yesandla ingabukeka ikhanga kusengaphambili, kodwa ikhwalithi yokukhiya engaguquki idala ukubambezeleka kokuhlolwa, ukulungiswa kwensimu, kanye nokushintsha okungenzeka. Uma umsebenzi unenani eliphezulu lokuphindaphinda, ithuluzi ngokwalo liba yingxenye yokulawula inqubo. Yingakho amaqembu okuthenga evame ukulinganisa ipulatifomu eyodwa yokufaka kuyo yonke indawo, bese eyihlanganisa nobubanzi be-tie obuvunyelwe kanye namamaki ukuze kube lula ukuqeqeshwa kanye ne-QA.

Ukukhetha ithuluzi lokubopha ikhebula lensimbi engagqwali ngokwendawo yesicelo

Indawo yokusetshenziswa kufanele ishukumise ukukhetha izinto ngaphambi kokukhetha amathuluzi.

Isisekelo solwazi sicacile: i-304 iyindlela ejwayelekile, kuyilapho i-316 ivame ukukhethwa ngenxa ye-chloride eqinile noma ukuvezwa komswakama. Lokho kusho ukuthi ithuluzi elifanayo lokufaka lingafaneleka kuwo wonke amaphrojekthi, kodwa ukucaciswa kwe-tie ne-band kumele kushintshe ngokuhambisana nemvelo. Ezindaweni zezimboni zangaphandle, izikhungo zasogwini, noma izindawo eziseduze namakhemikhali, i-316 ivame ukuthandwa ngoba i-molybdenum ithuthukisa ukumelana nomgodi ezimweni ezithwala i-chloride. Ngomsebenzi wangaphakathi ongabizi kakhulu, i-304 inganele. Uma indawo ingangcolisi kakhulu kodwa isabelomali sinqunyelwe, i-430 isengacatshangelwa ezicelweni ezikhethiwe lapho isidingo sokugqwala siphansi khona.

Isimo somphezulu kanye nokuqina nakho kuthinta impumelelo yokuthengwa. I-stainless strip egoqekile ebandayo ivame ukuthandwa ngenxa yekhwalithi engcono yomphezulu, ukunemba kobukhulu, kanye nokwakheka, kuyilapho izinto ezigoqekile ezishisayo zifaneleka kakhulu ukusetshenziswa kwesakhiwo esijiyile. Ekwenziweni kwethayi kanye nezingxenye ezihlobene, ukubekezelelana kobukhulu kanye nokuvumelana kobubanzi kuthinta ngqo ukusebenza kokukhiya kanye nokulingana. Yingakho abathengi bonjiniyela kufanele bacele hhayi kuphela izinga, kodwa futhi nendlela yokucubungula, ukuqeda komphezulu, kanye nesimo sobunzima. Lokhu akuyona imininingwane emincane; kuthinta umuzwa wokufakwa, ukuthembeka kokukhiya, kanye nokuqina kwesikhathi eside.

Kubathengi abaqhathanisa imindeni yemikhiqizo, kuyasiza ukubuyekeza ulwazi olubanziumucu wensimbi engagqwaliisisekelo sokuhlinzeka kanyeamakhoyili ensimbi engagqwaliuchungechunge lomthombo, ngoba ikhwalithi ye-strip ehambisanayo ivame ukusekela ukusebenza kwe-tie okuzinzile. Uma ukusetshenziswa kokugcina kuyihlelo lokufaka elilawulwayo, abathengi kufanele baphathe i-tie, i-strip, kanye nethuluzi lokufaka njengesistimu eyodwa kunezinto ezintathu ezizimele zomugqa.

Lokho abathengi bobunjiniyela okufanele bakuhlole ngaphambi kokuthenga ngobuningi

Ukuthengwa kwezimpahla ngobuningi kuyaphumelela uma kubhalwa imigomo yekhwalithi ngaphambi kwe-oda lokuthenga.

Ngaphambi kokufaka i-oda elikhulu, abathengi bobunjiniyela kufanele bachaze ububanzi be-tie, indlela yokukhiya, ububanzi be-bundle diameter, ukuziphatha kokucindezeleka kwamathuluzi, kanye nesigaba sokugqwala esidingekayo. Ngaphandle kwaleyo mininingwane, amaqembu okuthola izinto avame ukuqhathanisa imikhiqizo engahlobene futhi adale ukungalingani okungagwenywa. Ithuluzi le-stainless steel cable tie alilona elivamile; kumele livumelane nobukhulu be-band ye-tie, isitayela se-buckle, kanye namandla okufaka ahlosiwe. Kumaphrojekthi lapho umqhubi ofanayo efaka khona izinkulungwane ze-tie, ithuluzi elizinzile linganciphisa isikhathi sokuqeqesha futhi lithuthukise ukuhambisana. Kumaphrojekthi anamaqembu axubile, linganciphisa namaphutha okufaka.

Uhlu lokuhlola lokuthenga olusebenzayo kufanele luhlanganise izinto ezilandelayo:

• Ukuhambisana kobubanzi bebhendi nobukhulu
• Izinto zokubopha eziqondiwe: 304, 316, noma elinye izinga elivunyiwe
• Ukuchayeka okulindelekile: ngaphakathi, ngaphandle, olwandle, amakhemikhali, noma izinga lokushisa eliphezulu
• I-cadence yokufaka edingekayo ngehora noma ngeshifti ngayinye
• Izindlela zokuhlola zobuqotho bokukhiya kanye nokuphepha kwephakheji
• Izingxenye ezisele kanye nokutholakala kokulungiswa

Kuzinhlelo ze-OEM, ukulandeleka kubalulekile. Uma iphrojekthi idinga ukulawulwa kweqoqo, cela amadokhumenti ezindawo kanye nemininingwane yokwakha ehambisanayo kumhlinzeki. Uma ukufakwa kuhlobene nokuhlolwa kwekhwalithi, engeza izindlela zokwamukela amandla okukhiya, ukuphindaphindeka, kanye nokuhlolwa okubonakalayo. Yilapho ukubopha kobunjiniyela kuyeka khona ukuba ukuthengwa kwempahla bese kuba inqubo elawulwayo.

Idatha yokusebenza kanye nezindinganiso ezibalulekile ekufakweni kwensimbi engagqwali

Izinqumo zokuthenga ziba zithembekile kakhulu uma zixhunyaniswa nezindinganiso nezindlela zokuhlola.

I-ISO 9227 iyireferensi evamile yokuhlolwa kwe-salt spray yokuqhathaniswa kokugqwala, kanti i-ASTM A240 isetshenziswa kabanzi ezidingweni ze-chromium kanye ne-chromium-nickel stainless steel plate, ishidi, kanye ne-strip plate. Ngokwesimo semishini, i-ASTM A313 ihlanganisa ucingo lwe-spring steel stainless steel, oluvame ukubaluleka lapho abathengi behlola ukuziphatha okufana nentwasahlobo noma ukuhambisana kwezinto ezakhiweni ezakhiwe. Lezi zindinganiso azithathi indawo yokuhlolwa kohlelo lokusebenza, kodwa zakha isisekelo sezimangalo zomhlinzeki kanye nokuhlolwa kokuqhathanisa. Ngolimi lokuthenga, izindinganiso ziwumehluko phakathi kwesicelo sokumaketha kanye nencazelo eqinisekisiwe.

Idatha yobuningi nayo iyasiza ekubekeni okulindelwe. Izinhlelo zokubekezelelana ze-ISO zivumela abathengi ukuthi bachaze ukulawula okulinganayo esikhundleni sokuthembela ezincazelweni ezingacacile. Isibonelo, ekusetshenzisweni kwe-strip enembile, ukubekezelelana kobukhulu, ukubekezelelana kobubanzi, kanye nokuba flat yizona zinto ezibangela ukusebenza kahle kwangempela. Ithuluzi lingase libe ngcono ngokomshini, kodwa uma izinto zokubopha zingahambisani, umphumela wokufakwa usazoshintsha. Yingakho abathengi abanokwethenjelwa okuphezulu bevame ukucacisa hhayi nje kuphela ibanga elingagqwali, kodwa futhi nebhendi yobukhulu be-strip, ifasitela lokubekezelelana kobubanzi, kanye nesimo sobuso.

Lapho abasebenzisi bebuza mayelana nokusetshenziswa kwe-throughput, impendulo engcono kakhulu ivame ukuncika enqubweni. Ithuluzi elenziwa ngesandla linganele ngokugcwele ngevolumu ephansi kuya kwephakathi, kodwa izinhlelo zobunjiniyela obukhulu zivame ukuthethelela ukuhamba komsebenzi okulawulwa kakhulu ngoba ukuphindaphindeka kunciphisa ukusebenza kabusha. Ezindaweni eziningi zasefektri nasensimini, izindleko zokulingana okukodwa okuhlulekile zingadlula ukonga okulinganiselwe kusuka ekukhetheni kwebanga eliphansi, ikakhulukazi uma ukufinyelela kunzima noma isikhathi sokungasebenzi sibiza kakhulu.

Uma ithimba lakho lokuthola ulwazi lakha uhlelo olukhulu lokuqinisa, kungase kube usizo futhi ukubukezaizibambo zensimbi engagqwalikanyemayelana nekhasilokho kuchaza ikhono lokukhiqiza kanye nokulawula ikhwalithi. Lawo makhasi asiza abathengi ukuqinisekisa ukuthi umhlinzeki angakwazi yini ukusekela izidingo zokubopha zobunjiniyela ezibanzi, hhayi nje umugqa owodwa womkhiqizo.

Izindleko, abasebenzi, kanye nenani eliphelele ezinhlelweni zamathuluzi okufaka ngobuningi

Ukuthengwa kwempahla ngobuningi kuvame ukufaneleka ngokonga abasebenzi kanye nokwehluleka okuncane, hhayi ngentengo yamathuluzi kuphela.
