Kwihlabathi leumbhobho wentsimbiukwenziwa kwezinto, ukuchaneka akuyonjongo nje kuphela—yimfuneko esemthethweni neyokhuseleko. Nokuba uqhuba umzi-mveliso kuMzantsi-mpuma we-Asia okanye ufuna iityhubhu zokwakha kwiprojekthi eMntla Melika, uhlala udanisa phakathi kwamazwe amabini: inkqubo ye-metric kunye nenkqubo yobukhosi.
Ukuguqulwa "okusondeleleneyo" kunokusebenza kucingo oluya ebaleni, kodwa xa usebenzaI-APIokanye imigangatho ye-ASTM, ukuba buthathaka ngee-intshi ezimbalwa kunokukhokelela ekuphazameni okukhulu kwemibhobho, ukuthunyelwa okungafunwayo, okanye ukudityaniswa kwemisonto okungenakuhlalisa. Kulapho itshathi yokuguqula iimilimitha ukuya kwii-intshi ethembekileyo iba sisixhobo esibalulekileyo kwivenkile yakho.
Umgangatho: Kutheni i-25.4 iyiNombolo yoMlingo
Kwimveliso yeepayipi, yonke into ijikeleza kwiDayamitha Yangaphandle (OD) kunye neNqanaba loDonga (WT). Nangona uninzi lwehlabathi lusebenzisa iimilimitha, imakethi yaseMelika isafuna yonke into ngee-intshi zedesimali kunye "neeshedyuli" zeepayipi.
Ibhulorho esemgangathweni yoshishino injalo kanye25.4.
I-Metric ukuya kwi-Imperial:mm/ 25.4 = intshi
Ukusuka kwi-Imperial ukuya kwi-Metric:ii-intshi ziphindwe ngama-25.4 = mm
Ukuba ukwifektri kwaye kufuneka uguqule1.4mm ukuya kwii-intshiyeityhubhu yesakhiwo enodonga olubhityileyo, izibalo zikunika u-0.055118". Kwindawo yokuvelisa, sidla ngokuyinciphisa le nto ibe ziindawo ezine zedesimali: 0.0551". Elo nani lincinci ngumahluko phakathi kwemveliso esemgangathweni ophezulu kunye "neyesibini."
Itheyibhile yoGuqulo oluchanekileyo: Inch-mm Decimal
Kwimibhobho yentsimbi, asisebenzisi rhoqo amaqhezu afana ne-1/8" okanye i-3/16". Iingcali zemishini kunye nabahloli be-QC bafuna itheyibhile yokuguqula i-intshi ye-mm-decimal. Amaqhezu awacacanga kakhulu kwi-CNC pipe threading okanye uvavanyo lobukhulu be-ultrasonic.
Isifundo seTyala se-1.4mm: Kutheni iDesimali ibalulekile
Usenokuzibuza ukuba kutheni umenzi enomdla ngokukodwa kwi-1.4mm ukuya kwi-intshi. Kwimveliso yeIityhubhu zentsimbi ze-ERW, 1.4mm yindawo eqhelekileyo "emnandi" kwizicelo zesakhiwo esikhanyayo, ezifana neefreyimu zefenitshala okanye izixhobo zokukhupha umoya kwiimoto.
Ukuba iplani yomthengi wakho ifuna ubukhulu bodonga obuyi-0.055" kwaye isixhobo sakho sokugalela simiselwe ukuvelisa i-1.4mm, ngobuchwephesha ubonelela nge-0.0551". Kwipayipi enye, loo mahluko we-0.0001" awubonakali. Kodwa ukuba uthumela ipayipi engama-50,000 iinyawo, loo bukhulu bongezelelekileyo bongeza ubunzima obukhulu kwi-odolo iyonke. Ekubeni intsimbi idla ngokuthengiswa ngobunzima, ukuguqulwa okungachanekanga kunokulahla iikowuteshini zakho zempahla kunye nemida yenzuzo yakho.
Ubunzima bodonga kunye nokudideka "kokulinganisa"
Kwihlabathi leepayipi zentsimbi, itshathi yokuguqulwa kweemilimitha ukuya kwii-intshi idla ngokuba nzima yinkqubo ethi "Gauge". Ipayipi ethi "14-gauge" ayifani kuyo yonke indawo.
E-US, intsimbi ye-14-gauge idla ngokuthathwa njenge-0.0747".
Nangona kunjalo, iifektri ezininzi zamazwe ngamazwe ziya kubonelela ngombhobho we-2.0mm endaweni yawo, nto leyo eyi-0.0787".
Ukuba uthembele kwigama elifana nelithi "14-gauge" endaweni yokuguqulwa kwedesimali, ugqibela unemibhobho engafanelaniyo nee-couplings okanye izihlanganisi ezisetyenziswayo kweli candelo. Yiyo loo nto imveliso yanamhlanje isuka kumagama eegeyiji iye kwiinkcukacha ezingqongqo ze-mm-to-decimal-intshi.
Ukunyamezelana: Umgibe Ofihliweyo
Kwimveliso, akukho mbhobho ulingana ngokugqibeleleyo ne-1.4mm. Kukho "ukunyamezelana"—ngesiqhelo i-+/- 10%.
Ukuba uguqula i-1.4mm ibe yi-0.055 intshi, kodwa umgca wakho wemveliso unyuka uye kwi-1.35mm, ubukhulu bakho ngoku buyi-0.0531 intshi.
Ukuba iinkcukacha zeprojekthi zifuna ubuncinci be-0.054 intshi, yonke ibhetshi yakho ingaliwa. Xa usebenzisa itafile yokuguqula i-intshi mm-decimal, soloko ujonga uluhlu lokunyamezelana kwesixhobo sakho. Musa ukuguqula nje inombolo ekujoliswe kuyo; guqula amanani akho "omgangatho" kunye "nesilingi" ukuqinisekisa ukuba uhlala ngaphakathi kweenkcukacha zomthengi.
