Ifom yoku-odola mayibandakanye ezi zinto zilandelayo ziyi-11:
1. Ubungakanani (iinyawo, iimitha okanye inani leentonga)
2. Igama lezinto eziphathekayo (umbhobho wentsimbi engenamthungo)
3. Amanqanaba (ali-16 ewonke: P1, P2, P22, P11, P22, P91)
4. Indlela yokuvelisa (ukugqiba okushushu okanye umzobo obandayo)
5. Sebenzisa enye yezi nkcukacha zilandelayo: 1), i-NPS kunye nobukhulu bodonga lombhobho inombolo ye-serial, 2), i-diameter yangaphandle kunye nobukhulu bodonga lwegama, 3), i-diameter yangaphandle kunye nobukhulu obuncinane bodonga, 4), i-diameter yangaphakathi kunye nobukhulu bodonga oluqhelekileyo , 5), i-diameter yangaphakathi kunye nemiyalelo yokuodola yobukhulu obuncinci bodonga
6. Ubude (bohlulwe kubude obusisigxina kunye nobude obungenasiphelo)
7. Ukugqiba ukuqhubekeka.
8. Iimfuno zokukhetha (uxinzelelo lwamanzi kunye nokuphambuka kobunzima obuvumelekileyo).
9. Iingxelo zovavanyo ezifunekayo (jonga i-A530).
10. Inombolo eqhelekileyo. 11Iimfuno ezizodwa okanye naziphi na iimfuneko ezongezelelweyo ozikhethelayo.
Izixhobo kunye nemveliso
1. Imibhobho yentsimbi ebizwa ngokuba yintsimbi ingagqitywa okanye ibanjwe ngokubanda, kwaye iye yafumana unyango lokugqibela olufunwa ngumgangatho.
2. Intsimbi ye-P2 kunye ne-P12 yebakala. La manqanaba mabini entsimbi kufuneka enziwe kusetyenziswa inkqubo yokunyibilika kweenkozo ezirhabaxa. Ukuba kukho iimfuno ezikhethekileyo zobungakanani bengqolowa okanye inkqubo ye-deoxidation, kufuneka kuvunyelwane ngayo ngumthengi kunye nomenzi wensimbi.
3. Unyango lobushushu
1. Ngaphandle kwe-PSC, i-P23, i-P91, i-P92, i-P122 kunye ne-P911 ye-grade steel kwaye njengoko kucacisiwe, onke amabakala emibhobho ebizwa ngokuba yi-nominal pipes iya kuphinda ifudunyezwe kwaye inikezelwe kwi-annealed ngokupheleleyo, i-isothermal annealed okanye i-normalized and tempered state. Ukuba kubonelelwe kwimeko yesiqhelo kunye nobushushu, ubuncinci bobushushu bobushushu beP5, P5B, P9, P21 kunye neP22 grade steel iya kuba yi-675 ° C. Ubuncinci bobushushu bobushushu bentsimbi ye-P1, i-P2, i-P11, i-P12 kunye ne-P15 yodidi kufuneka ibe yi-650 ℃
2. Ukunyangwa kobushushu bokugqibela be-P92 kunye ne-P911 ye-grade steel kufuneka ibe yinto eqhelekileyo ubuncinane be-1040 ℃ kunye nokufudumala ubuncinane be-730 ℃.
