Amanqaku abalulekileyo ekufuneka uwaqaphele xa uthenga (Amanqaku aphambili kwii-odolo zobuNjineli
Cacisa imigangatho yobugcisa kunye neemfuno zenqanaba lentsimbi
Umbuzo wetyala:
Ekuqaleni umthengi ucele kuphela u-"S355" ngaphandle kokuchaza isimamva (esifana no-J2H, J0H), nto leyo eyabangela ukuba umthengisi avelise ngokwe-S355J0H(ngaphandle kweemfuno zempembelelo yobushushu obuphantsi), kodwa iprojekthi yokwenyani iyafunekaS355J2H(ukuqina kwempembelelo kwi -20℃).

Isisombululo:

Cacisa ngokucacileyo uhlobo olupheleleyo lwentsimbi (njenge-S355J2H) ngolandelelwano.

Bonisa ubushushu bovavanyo loxinzelelo (njengeCharpy V-notch kwi -20℃).

2. Ubukhulu kunye nokunyamezela (Ukuthintela iingxaki zokufakela)
Umbuzo wetyala:
Ububanzi bangaphandle bebhetshi ethile yeepayipi zentsimbi yayiyi-Ø219.1mm (+1.5% yokunyamezelana okuvumelekileyo), kodwa umlinganiselo wokwenyani ufikelele kwi-Ø222.5mm, nto leyo ebangele ukuba i-flange ingakwazi ukufana nendawo.

Isisombululo:

Beka unyamezelo olungqongqo kwisivumelwano (njengonyamezelo lweKlasi D1 kwi-EN 10210-2).

Funa ingxelo yokuhlolwa ngumntu wesithathu (njenge-SGS/BV) ukuqinisekisa ubukhulu.

3. Imeko yokuhanjiswa (Ichaphazela ukusebenza kwezinto)
Umbuzo wetyala:
Umthengi akakhange ayichaze imeko yokuhanjiswa. Umthengisi usebenzisa i-"AR" (As-Rolled), kodwa umyili ufuna i-"+N" (ukulungisa imeko) ukuqinisekisa ukusebenza kwe-welding.

Isisombululo:

Cacisa iimfuno zonyango lobushushu (ezifana no-"+N" okanye "+AR").

Jonga ukuba isatifikethi sesiqinisekiso somgangatho sibonisa imeko yonyango lobushushu na.

4. Ukuhlolwa kunye neSatifikethi (Ukuthintela iingxabano zomgangatho)
Umbuzo wetyala:
Umthengisi unike isatifikethi se-EN 10204 3.1, kodwa umthengi ucele isatifikethi se-3.2 (esiqinisekiswe yilabhoratri ezimeleyo), nto leyo ebangele ukulibaziseka kokususwa kwempahla kwirhafu.

Isisombululo:

Bonisa uhlobo lwesatifikethi (esifana ne-EN 10204 3.1/3.2) ngokolandelelwano.

Izinto zokuhlola ezikhethiweyo (ezifana nokufunyanwa kweziphene ze-UT, uvavanyo lokuxinana, uvavanyo lokuchaphazela).

5. Unyango lomphezulu kunye nokulwa nokugqwala (okuchaphazela ubomi benkonzo)
Umbuzo wetyala:
Iipayipi zentsimbi ziyasetyenziswa kwiindawo ezikufutshane nonxweme, kodwa akufuneki kufakwa ulwelo oluchasene nokugqwala, nto leyo ekhokelela ekugqwaleni ngexesha lokuthuthwa kwaye ifuna unyango olongezelelweyo lokuqhumisa isanti.

Isisombululo:

Cacisa indlela yokunyanga umphezulu (njengokuqhumisa isanti nge-Sa2.5, ukugquma nge-galvanizing okanye ukusebenzisa i-oyile yokulwa nomhlwa).

Cacisa indlela yokupakisha (efana nokubopha + ifilimu engangenisi manzi).

6. Ixesha lokuHanjiswa kunye neLogistics (Ukuthintela izohlwayo zokulibaziseka)
Umbuzo wetyala:
Umthengisi ulibazise imveliso ngenxa yokunqongophala kwezinto zokwenza imveliso, kodwa isivumelwano asizange sichaze isohlwayo sokuhlawula emva kwexesha. Ngenxa yoko, umthengi wanyanzeleka ukuba alungise isicwangciso sokwakha.

Isisombululo:

Faka iiMali eziLiquidated Damages kwikhontrakthi, ezifana ne-0.5% yentlawulo yeveki nganye yokulibaziseka.

Cela umthengisi ukuba anike ingxelo yenkqubela phambili yemveliso.

7. Imigaqo yokuhlawula kunye neleta yetyala (ukuncitshiswa komngcipheko)
Umbuzo wetyala:
Umthengi wavula i-100% LC xa wayeyibona, kodwa ngexesha lokuhlolwa, kwafunyaniswa ukuba ubukhulu bodonga lombhobho wentsimbi abulingani. Emva kwengxabano, ibhanki yala ukwenza intlawulo.

Isisombululo:

Intlawulo ngezavenge iyamkelwa (njengediphozithi ye-30% kunye ne-70% ngokusekelwe kwikopi yengxelo yebhili yomthwalo + ingxelo yokuhlolwa).
