I. Imigaqo-siseko yeValve Sourcing
Iivalvu zoshishino kunye nezixhobo zazo zizinto ezibalulekileyo kwimisebenzi kwiinkqubo zolawulo lolwelo. Impumelelo yokuthengwa kwempahla kwihlabathi liphela ayixhomekekanga ekufumaneni ixabiso eliphantsi lokuqala, kodwa ekuqondeni iintsika ezine ezisisiseko zobunjineli kunye nokuthobela imithetho.
1. Ukufanisa okuqhelekileyo
Ukuqinisekisa ukuba imigangatho yobukhulu kunye noyilo ihambelana ngokugqibeleleyo. Ukungalingani kwiimilinganiselo zobuso ngobuso (umz., i-ASME B16.10 vs. EN 558) okanye ukubhola iflange kunokukhokelela ekusileleni okukhulu kokufakelwa kunye nokulibaziseka kweprojekthi. Zonke iinkcukacha kufuneka ziqinisekiswe.
2. Ukuguquguquka kwezinto kunye nemeko
Ukukhethwa kwezinto kufuneka kuthathele ingqalelo ukubola kolwelo, ukulinganiswa koxinzelelo-lobushushu, ukuxinana kwe-cavitation, kunye nokukhazimla. Ukusebenzisa iintsimbi eziqinileyo ezimbini okanye ii-alloys ezingaqhelekanga kuyimfuneko kwiimeko ezinzima zenkonzo ezifana noxinzelelo oluphezulu lwe-H2S.
3. Iifayile zokulandelelwa kunye nomgangatho
Amaxwebhu apheleleyo awaxoxiswana ngawo. Oku kuquka iiNgxelo zoVavanyo lweMill ze-EN 10204 3.1/3.2 (ii-MTR), ukuchongwa kwezinto ezichanekileyo (i-PMI), kunye namanani obushushu ashicilelwe kwimizimba ebonakalayo ukuqinisekisa ukulandeleka kwe-metallurgical eyi-100%.
4. Imithetho yeMarike ekujoliswe kuyo
Ukuthobela imithetho yengingqi kulawula ukungena kwimarike. Nokuba ngumyalelo we-CE/PED we-European Union, i-EPA fugitive emission consent decrees e-USA, okanye isiqinisekiso se-EAC se-Eurasian Customs Union.
II. Uhlu lweeMveliso kunye noGxilo loBugcisa
Ukuqonda ngokubanzi izinto zevalvu kubalulekile ukuze kufunyanwe imveliso kwihlabathi liphela ngempumelelo. Sihlela iimveliso zibe ngamanqanaba amathathu obuchwephesha ahlukeneyo, ngalinye lifuna iindlela ezithile zokuvelisa nokuhlola.
