Ishishini lokwakha iinqanawa liye lafumana inkqubela phambili emangalisayo kwinkulungwane edlulileyo, liqhutywa yimfuno yeenqanawa ezomeleleyo, ezihlala ixesha elide, nezisebenza kakuhle. Enye yezinto eziphambili kule nguqu kukuphuhliswa kweentsimbi zokwakha iinqanawa, ezivela kwiintsimbi zokuqala ezithambileyo ezifanaA36ukuya kwiintsimbi ezinamandla aphezulu, ezinobushushu obuphantsi ezifanaI-EH36Ukuqonda olu phuhliso kubalulekile kwiinjineli, abakhi beenqanawa, kunye nabakhi beenqanawa ukuze benze izigqibo ezinolwazi xa bekhetha izixhobo zeenqanawa zanamhlanje.
Eli nqaku liphonononga ukuvela kweentsimbi zokwakha iinqanawa, iimpawu zazo zoomatshini, usetyenziso, kunye neendlela zexesha elizayo eziza kuguqula eli shishini.
Iintsimbi zokwakha iinqanawa zokuqala: A36
Intsimbi ye-A36imele enye yeentsimbi zokwakha iinqanawa ezisetyenziswa kakhulu. Njengentsimbi ethambileyo nengenakhabhoni iphantsi, yayinika amandla aneleyo kwiinqanawa zokuqala kunye nezakhiwo eziphakathi zaselunxwemeni. Iimpawu zayo zoomatshini zaziquka:
-
Amandla okuvelisa angama-250 MPa
-
Amandla okutsalwa aphakathi kwama-400 nama-550 MPa
-
Ukwandiswa malunga ne-20%
Intsimbi ye-A36 yayinika ukudityaniswa kakuhle kunye nokuguquguquka okugqwesileyo, okwenza ukuba ifaneleke ukwenziwa kusetyenziswa iindlela zokuwelda kunye nezokugoba kwasekuqaleni. Nangona kunjalo, njengoko iinqanawa zazisiba nkulu kwaye zifuna ukusebenza ngcono kwiindawo ezinzima, imida ye-A36 yabonakala.
Imida ye-A36
Nangona i-A36 yayisebenza kakuhle ekwakhiweni kweenqanawa kwasekuqaleni, yayineengxaki ezininzi:
-
Amandla Asezantsi:Kwakufuneka iipleyiti ezityebileyo ukuze kuhlangatyezwane neemfuno zesakhiwo, nto leyo eyandisa ubunzima benqanawa.

Ezi mingcele zaqhuba uphuhliso lweentsimbi zokwakha iinqanawa eziqinileyo neziqinileyo.
Uphuhliso: AH36 kunye neDH36
Ngokufika kokwakhiwa kweenqanawa zanamhlanje, iintsimbi ezifanaAH36kwayeDH36zaziswa ukujongana nemida yentsimbi ethambileyo.
-
AH36(i-American Bureau of Shipping approval) yintsimbi enamandla aphezulu, engenangxubevange ininzi eyenzelwe iimeko eziphakathi ukuya kwezinzima. Ibonelela ngezi zinto zilandelayo:
-
Amandla amancinci okuvelisa isivuno angama-355 MPa
-
Amandla okutsalwa angama-490 ukuya kuma-620 MPa
-
Ukwandiswa okugqwesileyo kunye nokuqina kwempembelelo
-
-
DH36(Imvume yobhaliso lukaLloyd) ineempawu ezifanayo kodwa igxininisa ukusebenza okulinganayo koomatshini okufanelekileyo kumaqonga aselwandle kunye nokusetyenziswa okuqhelekileyo kolwandle.
Ezi ntsimbi zinciphise ubukhulu bepleyiti ngaphandle kokuphazamisa ulwakhiwo, nto leyo evumela ukuba kubekho iinqanawa ezilula nezisebenza kakuhle.
Iimeko Ezigqithisileyo: EH36
Imfuneko yeenqanawa ezisebenza kwiindawo zaseArctic nakwimimandla engaphantsi kwezulu ikhokelele ekuphuhlisweniIntsimbi ye-EH36. Igama elithi “E” libonisa ukuqina okuphuculweyo kobushushu obuphantsi, nto leyo eyenza ukuba ifaneleke kwiinqanawa zodidi lomkhenkce, izakhiwo zaselwandle, kunye nokusetyenziswa kwamanzi abandayo. Iimpawu eziphambili ze-EH36 ziquka:
-
Amandla okuvelisa angama-355 MPa ukuze ubukhulu bufikelele kwi-50 mm
-
Amandla okutsalwa angama-490 ukuya kuma-620 MPa
-
Ukuqina okuphezulu kwempembelelo kumaqondo obushushu aphantsi njenge--40°C
I-EH36 ivumela iinjineli ukuba zakhe iinqanawa ezingapheleli nje ekubeni zomelele kodwa ezikhuselekileyo nezithembekileyo kwiimeko ezinzima.
Uthelekiso lweePropati zoMatshini
Utshintsho oluvela kwi-A36 ukuya kwi-EH36 lubonisa uphuculo olubalulekileyo kwiimpawu zoomatshini ngokuhamba kwexesha:
| Ibanga lentsimbi | Amandla okuKhula (i-MPa) | Amandla okuThamba (MPa) | Ukwandiswa (%) | Ukuqina Kwempembelelo |
|---|---|---|---|---|
| A36 | 250 | 400-550 | 20 | Iphakathi |
| AH36 | 355 | 490-620 | 21 | Phezulu |
| DH36 | 345 | 470-630 | 19 | Phezulu |
| I-EH36 | 355 | 490-620 | 21 | Iphezulu (-40°C) |
Le theyibhile ibonisa ukuqhubela phambili kwamandla, ukuqina, kunye nokusebenza kakuhle kubushushu obuphantsi, nto leyo evumela iinqanawa ezikhuselekileyo nezisebenza kakuhle.
