Ungaze ubhale “i-16-gauge sheet metal” kwi-order yokuthenga. I-16-gauge carbon steel sheet yi-1.52 mm. I-16-gauge aluminium sheet yi-1.29 mm. Loo mahluko we-0.23 mm unokonakalisa i-accent assembly.
2. Ukudibanisa iGauge neMil
I-mil enye ilingana ne-intshi eziyi-0.001. Ishiti yentsimbi yekhabhoni ene-gauge ezingama-20 imalunga ne-intshi eziyi-0.036, okanye i-36 mil. Abanye abathengi babhidanisa amanani e-gauge nobukhulu be-mil baze bagqibela ngoku-odola izinto ezingalunganga ngokupheleleyo.
3. Ukungawunaki Ubukhulu Bokugquma Kwiphepha Eligayiweyo
I-galvanized steel gauge ibandakanya i-zinc coating. Ukuba ufuna ubukhulu besiseko sentsimbi ethile ukuze udibanise okanye ubale ulwakhiwo, chaza ubukhulu besiseko sentsimbi ngokwahlukeneyo. I-coating idla ngokongeza i-0.02 ukuya kwi-0.04 mm kwicala ngalinye.
4. Ukucinga ukuba bonke ababoneleli basebenzisa iMigangatho efanayo yokulinganisa
Umthengisi eTshayina unokubhekisa kwi-GB/T. Umthengisi eYurophu unokubhekisa kwi-EN. Umthengisi eMelika unokubhekisa kwi-ASTM. Soloko uchaza umgangatho kwi-odolo yakho yokuthenga.
5. Ukucacisa iGauge xa ubukhulu beDecimal buza kuba bucacile
Xa uthenga izinto kwamanye amazwe, chaza ubukhulu bazo ngeemilimitha. Oku kususa ukungacaci kakuhle kwaye kunciphisa umngcipheko wokunxibelelana kakubi phakathi kwemiqobo yolwimi.
6. Ukulibala Ububanzi kunye noBude bokunyamezelana
Ubukhulu abukuphela kobukhulu obubalulekileyo. I-ASTM A480 ikwachaza ububanzi, ubude, i-camber, kunye nokunyamezelana kobubhetyebhetye. Iphepha elingaphandle kweflethi linokubangela iingxaki zokusebenzisa izixhobo zebrake yokucindezela nokuba ubukhulu bugqibelele.
Ukuze ufumane okungakumbi ngokukhethwa kwezinto kunye nokuphepha iimpazamo zeenkcukacha, jonga yethu uthelekiso lwentsimbi engatyiwayo vs intsimbi yekhabhoni.
Imibuzo ebuzwa qho
Yeyiphi engqindilili, i-16 yegeji okanye i-18 yegeji?
Igeyiji engama-16 ijiya kunegeyiji engama-18. Kwintsimbi yekhabhoni, i-16 GA ilinganisa i-1.52 mm ngelixa i-18 GA ilinganisa i-1.21 mm. Inani elisezantsi legeyiji lisoloko libonisa izinto ezityebileyo.
Yintoni intsimbi ye-20 gauge kwi-mm?
Intsimbi yekhabhoni ene-gauge engama-20 imalunga ne-0.91 mm (0.036 intshi) ubukhulu. Kwintsimbi engagqwaliyo, i-20 GA imalunga ne-0.95 mm. Kwi-aluminium, i-20 GA imalunga ne-0.81 mm.
Ingaba igeyiji yentsimbi engagqwaliyo iyafana negeyiji yentsimbi?
Inombolo yegeyiji iyafana, kodwa ubukhulu bokwenyani buyahluka. Ishiti yentsimbi engatyiwayo kwigeyiji ethile ityebile kancinci kunentsimbi yekhabhoni kwigeyiji efanayo. Umzekelo, intsimbi engatyiwayo ene-gauge eyi-16 yi-1.59 mm, ngelixa intsimbi yekhabhoni ene-gauge eyi-16 yi-1.52 mm.
Ingakanani ubukhulu besinyithi se-26 gauge?
Intsimbi yekhabhoni ene-gauge engama-26 imalunga ne-0.46 mm (0.018 intshi) ubukhulu. Ithathwa njengesinyithi esincinci kwaye isetyenziswa kakhulu ekufakeni uphahla, ukukhazimla, kunye neepaneli ezikhaphukhaphu.
Yintoni gauge yintsimbi eyi-1 mm?
Intsimbi eyi-1 mm imalunga ne-19 gauge Kwinkqubo yeGauge eQhelekileyo yoMenzi wentsimbi yekhabhoni. Kwintsimbi engagqwaliyo, i-1 mm ikufutshane ne-20 gauge.
Ndingayisebenzisa itshathi efanayo yokulinganisa i-aluminiyam kunye nentsimbi?
Hayi. I-Aluminium isebenzisa inkqubo yokulinganisa iBrown & Sharpe (AWG), ngelixa intsimbi isebenzisa iStandard Gauge yoMenzi. Iphepha le-aluminiyam eli-16-gauge liyi-1.29 mm, ngelixa iphepha lentsimbi eli-16-gauge liyi-1.52 mm. Sebenzisa itshati echanekileyo kwizixhobo zakho rhoqo.
Yintoni umahluko phakathi kwe-SWG kunye ne-AWG?
I-SWG (I-Standard Wire Gauge) yinkqubo yaseBritane esetyenziswa kakhulu kumazwe ase-UK nakumaCommonwealth. I-AWG (i-American Wire Gauge), ekwabizwa ngokuba yiBrown & Sharpe, yinkqubo yase-US esetyenziselwa iintsimbi ezingezizo iintsimbi. Inani elifanayo leegeyiji livelisa ubukhulu obahlukeneyo kwinkqubo nganye.
I-gauge iyichaphazela njani i-welding?
Iigeyiji ezincinci zifuna ubushushu obuphantsi kunye nesantya sokuhamba esikhawulezayo ukuthintela ukutsha. Ukuwelda iphepha le-26-gauge kunzima kakhulu kunokuwelda iphepha le-14-gauge. Xa udibanisa iigeyiji ezahlukeneyo, bhekisa ubushushu obuninzi kwisiqwenga esityebileyo.
Yeyiphi igeyiji endifanele ndiyisebenzise kwiiphaneli zangaphandle?
Kwiiphaneli zesakhiwo sangaphandle, i-gauge eyi-14 ukuya kwi-18 iqhelekile kwintsimbi nakwintsimbi engatyiwayo. Kwizigqubuthelo ezingezizo zesakhiwo kunye nophahla, i-gauge eyi-22 ukuya kwi-26 iqhelekile. Cinga nge-316 stainless steel okanye i-galvanized steel yokumelana nokugqwala kwiindawo zangaphandle.
Ndingayichaza njani i-gauge kwi-RFQ yamazwe ngamazwe?
Cacisa uhlobo lwezinto, ubukhulu bedesimali kwiimilimitha, kunye nomgangatho olawulayo. Umzekelo: “Ishidi lentsimbi engagqwaliyo engama-304, ubukhulu be-1.59 mm, ukunyamezelana ngokwe-ASTM A480 Table A1.1, 2B finish.” Oku kususa ukungaqondakali kwaye kukhusela umthengi kunye nomthengisi.
