I-AH36 vs DH36 vs EH36: Yeyiphi iBanga eliLungileyo kwiProjekthi yakho yokwakha iinqanawa?

Kwimizi-mveliso yanamhlanje yaselwandle naselwandle, ukukhetha uhlobo olufanelekileyo lwentsimbi yesakhiwo kubalulekile ukuqinisekisa ukhuseleko lwenqanawa, ukusebenza kwayo, kunye nokuqina kwayo ixesha elide. Phakathi kweentsimbi zokwakha iinqanawa ezinamandla aphezulu ezisetyenziswa kakhulu kukhoAH36, DH36, kunye ne-EH36Ezi zigaba zibalulekile kwizakhiwo zeenqanawa, iidekhi, amaqonga aselwandle, kunye nokusetyenziswa kolwandle okuxinzelelekileyo. Nangona zifana kakhulu, isigaba ngasinye sineemfuno ezahlukeneyo zokuqina, nto leyo eyenza ukuba zifaneleke kwiindawo ezithile nakwiimeko zeprojekthi.

Njengoko imigangatho yokwakha iinqanawa kwihlabathi liphela iqhubeka nokutshintsha kwaye amaqela okwakha ngokweendidi eqinisa imithetho yawo, iindawo zokuthengisa iinqanawa zifuna izixhobo ezinokubonelela ngokusebenza okuthembekileyo phantsi kwamaqondo obushushu ahlukeneyo kunye neemeko ezinefuthe eliphezulu.i-sakysteelbaxhasa abakhi beenqanawa kwihlabathi liphela ngokubonelela ngeepleyiti zentsimbi ze-AH36, DH36, kunye ne-EH36 ezinokulandeleka ngokupheleleyo, imvume yokuhlelwa, kunye nokuhambelana okuphezulu.

Eli nqaku libonelela ngothelekiso olupheleleyo lwe-AH36 vs DH36 vs EH36, luhlalutya iimpawu zoomatshini, ukusebenza kokuqina, iimeko zokusetyenziswa, kunye nesikhokelo sokuba loluphi uhlobo olufanelekileyo kwiiprojekthi ezahlukeneyo zokwakha iinqanawa.

Ukuqonda amaBanga aPhakamileyo oLwandle: AH36, DH36, EH36

I-AH36, i-DH36, kunye ne-EH36 ziintsimbi zokwakha iinqanawa ezinamandla aphezulu ezihlelwe phantsi kwe-ASTM A131 kwaye ziqinisekiswe yi-ABS, i-LR, i-DNV, i-BV, i-CCS, kunye neminye imibutho. Zifana ngokufanayo.amandla amancinci okuvelisa angama-355 MPa, nto leyo eyenza ukuba zilungele ukusetyenziswa kwezakhiwo ezifuna umgudu omkhulu.

Umahluko ophambili phakathi kwala mabanga nguukuqina kwempembelelokumaqondo obushushu ahlukeneyo ovavanyo:

  • AH36: Ivavanywe kwi-0°C

  • DH36: Ivavanyiwe kwi -20°C

  • I-EH36: Ivavanyiwe kwi -40°C

Amaqondo obushushu aphantsi ovavanyo abonisa ukuqina okuphezulu kunye nokumelana okukhulu nokuqhekeka okubuthathaka, okubalulekileyo kwiindawo ezibandayo okanye ezishushu kakhulu.

Uthelekiso lweePropati zoMatshini

Ibanga Unikeze Amandla Tensile strength Uvavanyo lweMpembelelo yoMbane Ukusetyenziswa Okuqhelekileyo
AH36 ≥ 355 MPa 490 ukuya kuma-620 MPa 0°C Iimozulu ezithambileyo neziphakathi
DH36 ≥ 355 MPa 490 ukuya kuma-620 MPa -20°C Iindawo ezibandayo kunye nezakhiwo ezinzima
I-EH36 ≥ 355 MPa 490 ukuya kuma-620 MPa -40°C Iindawo zaseArctic, iinqanawa zodidi lomkhenkce

Nangona zonke ezi zigaba zintathu zinika amandla afanayo, i-EH36 inikezela ngokusebenza okuphezulu kokuqina, ilandelwe yi-DH36, emva koko yi-AH36.

Ukufana kunye nomahluko kwiKhemikhali

Ukwakheka kweekhemikhali kuchaphazela ukudityaniswa, ukumelana nokugqwala, kunye nokuqina. Zonke ezi ntlobo zintathu ziquka:
