Ingcaciso emfutshane yeValve yoShishino lweVeki (2025): Umzimba weValve yeSango

Kutheni oku kubalulekile: Utshintsho kunye nokwakhiwa okutsha kuyahambelana, kuqinisa amandla kwiindawo zokusekwa/iiforiji, izixhobo zoomatshini ezinkulu, kunye neelabhoratri zomntu wesithathu. ukuqandisa kobugcisa phambi kwe-PO ihlala iyeyona nto ikhawulezayo yokuhambisa ngexesha elifanelekileyo.

Umfanekiso wemarike

• Umthamo omncinci wokufaka/wokubumba, umatshini wokulungisa ngokuchanekileyo, kunye nobungqina be-EN 10204 3.2.

• Tshixa i-scope kwangethuba ukuze ungaphindi uyitshintshe; ukuqandisa kube kanye kudla ngokusindisa iiveki ezi-1-3.

Izinto ezikhethiweyo (ezilungele inkonzo)

• I-A105/i-alloy ephantsi: inokuthenjwa kwinkonzo ngokubanzi, ukusebenza kakuhle koomatshini.

• 304/316L: amanzi/iikloridi ezithambileyo; i-316L inika umda ongcono wokugqwala.

• Imizimba ye-CF8/CF8M: vumela ijiyometri yevalvu eyinkimbinkimbi; phakamisa ukugubungela kwe-NDE.

• I-Duplex 2205: iikloridi + amandla; qinisekisa unyango lobushushu/ibhalansi yesigaba.

• Ubushushu obuphantsi/obumuncu: cacisa amaxabiso empembelelo kunye I-ISO 15156 / NACE MR0175ubulukhuni besiciko.

Imigangatho (caphula amabinzana, hayi izilogeni)

Uluhlu lweenkqubo kunye neziqendu ze I-ASME B16.34, I-API 600/602/6D, I-ISO 15156, I-ISO 15848kunye EN 10204 (3.1/3.2). Ncamathisela itheyibhile enephepha elinye yeemvume, amanqaku obungqina, kunye nezinto ezifunekayo (i-MTC, i-HT, i-NDE, amanzi/umoya, i-PMI, ubukhulu).

Ukuvelisa kunye ne-NDE

• Ukuhamba: i-preform → i-datums → iimpawu ezibalulekileyo → ukugqiba → uvavanyo.

• Indawo/ukuxinana kwesihlalo, ukuthambeka kwesango, ukuba tyaba kobuso obukhokelayo.

• I-NDE: UT/RT (ivolumu), i-MT/PT (umphezulu), i-PMI (ulawulo lokuxuba); bhukisha iilebhu kwangethuba.

• Sebenzisa i-FAI ukukhenkcisa iidatha, ukunyamezelana, kunye neendlela zokulinganisa.

Uvavanyo loxinzelelo kunye nokuvuza

Chaza indlela yokuvavanya, ubushushukunye ixesha lokubamba ye-hydro. Qinisekisa icala eliya kumacala omabini uvavanyo lwesihlalo/lokuvuza. Gcina iirekhodi ezipheleleyo (ii-ID zokulinganisa, iimeko, izinto eziqwalaselweyo), ungagcini nje ngokuba "NGOKUPHASA".

Isincamathiselo se-PO (uluhlu lokujonga oluncinci olunamanqaku ali-10)

1. Ubuso ngobuso; iflengi; ubuso bokuvala (RF/RTJ)

2. Inqanaba lezinto ezibonakalayo + imeko yonyango lobushushu

3. ububanzi be-NDE; isicwangciso sobungqina; inqanaba le-EN 10204

4. Ukunyamezelana (ukuxinana/ukuthe nkqo/uburhabaxa)

5. Vavanya ixesha eliphakathi/lobushushu/lokubamba; iklasi yokuvuza

6. Iinkcukacha zokumakisha/zokulandelela

7. Isicwangciso sokukhusela umphezulu

8. Iphakheji yamaxwebhu (i-MTC, i-HT, i-NDE, i-hydro/umoya, ubukhulu, i-CoC)

9. Ukupakisha/ii-Incoterms

10. Iziganeko ezibalulekileyo (i-preform, i-FAI, ingqina, i-hydro, ifestile yenqanawa)

Okukwintsusa: Iinkcukacha ezicacileyo zeevalvu, ubungqina obugxile kumanyathelo angenakutshintshwa, kunye nendlela ecacileyo ebalulekileyo igcina inkqubo yomzimba weevalvu iqikelelwa—ngokomgangatho, ngokuhambelana nomthetho, ngexesha.
