Izinto Ezibalulekile Okufanele Zicatshangelwe Zokuthenga

1. Cacisa ukulingana kwebanga ukuze ugweme ukungalingani

Uma ufaka ipayipi le-GB/T 8162 esikhundleni samamaki e-ASTM, qinisekisa izidingo zokusebenza ezigcwele. Ukulingana okuqondile kusebenza kuphela emithwalweni yesakhiwo esingaguquki; ngezidingo zokushisa, umthelela noma ukugqwala, ukwelashwa kokushisa okwengeziwe kanye ne-NDT kumele kuchazwe. Ungalokothi ufake ipayipi lesakhiwo elijwayelekile esikhundleni sezinhlelo zokusebenza zesevisi ekhethekile.

2. Cacisa Isimo Sokulethwa Nokwelashwa Kokushisa

I-GB/T 8162 inikezwa isesimweni sokugoqwa ngokuzenzakalelayo. Qondanisa ukwelashwa kokushisa nezidingo ze-ASTM:

Okulinganayo kwe-ASTM A53 Gr.B: Isimo sokugoqwa sanele.
Okulinganayo kwe-ASTM A106 Gr.B:Okujwayelekileukulethwa kuyadingeka.
Isevisi yomthwalo ophansi/oguquguqukayo: Kunconywa isimo esijwayelekile nesilinganiselayo noma esigoqekile esilawulwayo ukuze kube nokuqina okuqinisekisiwe.

3. Qinisekisa iklasi yokubekezelelana okunezilinganiso

Indinganiso ichaza izigaba ezimbili zokubekezelelana:

Ikilasi elijwayelekile: OD ±0.75%, WT +12.5% ​​/ -10%, yezakhiwo ezijwayelekile zokwakha.
Isigaba esinembile kakhulu: OD ±0.5%, WT ±10%, sezakhiwo zemishini ezinezidingo zokulingana okuqinile. Njalo chaza isigaba sokubekezelelana ngokwezidingo zokufakwa ukuze ugweme izinkinga zokufaneleka endaweni.

4. Vumelana Ngezidingo Zokuhlola Ne-NDT

Ipayipi lesakhiwo elijwayelekile: Ukuhlolwa kwe-hydrostatic okuphoqelekile ngokwejwayelekile.
Izakhiwo ezithwala umthwalo ezibalulekile:Ukuhlolwa kwe-Ultrasonic (UT)Kunconywa ukuthola imifantu yangaphakathi kanye nama-lamination.
Amaphrojekthi okuthumela ngaphandle: Ukuhlolwa komuntu wesithathu ngemibiko eyaziwayo emhlabeni wonke kungahlelwa.

5. Imibhalo Esezingeni Eliphezulu Nokwamukelwa Kwephrojekthi

Iqoqo ngalinye kumele linikezwe isitifiketi sokuhlolwa kwe-Mill esigcwele esihlanganisa inombolo yokushisa, ukwakheka kwamakhemikhali, izakhiwo zemishini, ukuqinisekiswa kobukhulu kanye namarekhodi okwelashwa kokushisa. Kumaphrojekthi aphesheya, qinisekisa ifomethi yedokhumenti kanye nezidingo zolimi kusengaphambili ukuze uhlangabezane nezindinganiso zokwamukelwa kwamakhasimende kanye nabahloli.

6. Qinisekisa Ukuvunyelwa Kokufaka Esikhundleni Kwephrojekthi ye-ASTM

Kumaphrojekthi e-EPC aphesheya noma atshalwe kwamanye amazwe, hlala uthumela amadokhumenti okulingana kwebanga bese uthola imvume yamakhasimende/unjiniyela ngaphambi kokufaka ipayipi le-GB esikhundleni sezinto ezichazwe yi-ASTM, ukuze ugweme izingozi zokwamukelwa.

Kungani Umthombo Uvela ku-SANONPIPE?

Njengomthengisi wamapayipi ensimbi ezimbonini okhethekile, i-SANONPIPE inikeza ukuthengwa kwamapayipi e-GB/T 8162 okuphumelelayo nokungahluphi:

1. Isitoko Esilungele Usayizi Ogcwele Ukuze Silethwe Ngokushesha

Sigcina uhlu olubanzi lwamapayipi angenamthungo e-GB/T 8162 kuwo wonke amabanga nosayizi, kusukela ku-18 mm kuya ku-630 mm OD kanye nobukhulu bodonga obungu-2.5 mm kuya ku-40 mm. Imininingwane ejwayelekile ithunyelwa zingakapheli izinsuku ezingu-3-5 zokusebenza; ama-oda aphuthumayo angathunyelwa ngalolo suku, kususwe izikhathi zokuhola zemishini ende.

2. Ukulingana Okunembile kwe-ASTM kanye Nokushintshaniswa Okungabizi Kakhulu

Sinikeza imibhalo ephelele yokulingana kwebanga le-ASTM kuya ku-GB, ehambisana ngokunembile ne-A53, A106, API 5L kanye nezinye izincazelo zase-US. Uma kuqhathaniswa nepayipi le-ASTM elingenisiwe, ikhambi lethu elilinganayo le-GB linciphisa izindleko ngo-15–30% ngezikhathi zokuhola ezimfushane kakhulu.

3. Ukulawulwa Kwekhwalithi Okuqinile kanye Nemibhalo Ephelele

Wonke amapayipi angenayo ahlolwa ngokuzayo ngobukhulu, ikhemikhali kanye nezakhiwo. Iqoqo ngalinye lihambisana nemibhalo esezingeni eliphelele, kanye ne-MTC ezilimi ezimbili etholakalayo ukuhlangabezana nokwamukelwa kwasekhaya, ukuvunyelwa kwentela kanye nezidingo zokuhlolwa kwephrojekthi yamazwe ngamazwe.

4. Ukucubungula Okunenani Elingeziwe Kokuma Kanye

Sinikeza izinsizakalo zokusika ngokunembile, ukugoba ekugcineni, ukufaka i-galvanizing, ukumboza kanye nokumaka. Amapayipi afika elungele ukufakwa, aqede ukwenziwa kwesibili futhi anciphise umthwalo womsebenzi endaweni.

5. Imigomo Yokuhweba Eguquguqukayo kanye Nesevisi Yomhlaba Wonke

Sisekela ukulethwa kwempahla ngaphakathi, i-FOB, i-CIF, i-DAP kanye nezinye i-Incoterms, ngemibhalo ephelele yokuthumela impahla kwamanye amazwe ehlanganisa ukuvunyelwa kwempahla yasekhaya, izitifiketi zokuhlola kanye nesitifiketi semvelaphi. Sisebenzela ukwakhiwa kwempahla ngaphakathi, ama-OEM emishini, abathengisi bokuthumela impahla kwamanye amazwe kanye nabakhi be-EPC bamazwe ngamazwe ngezixazululo zokuphakelwa eziklanyelwe wena.

Isiphetho

Ipayipi lensimbi elingenamthungo le-GB/T 8162, elinesistimu yalo ejwayelekile evuthiwe, ukusebenza okulinganiselayo kanye nenzuzo eqinile yezindleko, liyindlela engcono kakhulu esikhundleni sepayipi lesakhiwo le-ASTM ukuze kuthuthukiswe izindleko. Ukuqhathaniswa okunembile kwamazinga, ukucaciswa okucacile kwezimfuneko kanye nokulawulwa kwekhwalithi okuqinile kuyizihluthulelo zokuqinisekisa ukuphepha kwesakhiwo kanye nomnotho wephrojekthi.

Njengoba inenqwaba yempahla elungele ukusetshenziswa, ukufanisa ubuchwepheshe obuchwepheshile kanye nezinsizakalo ezisekelayo eziphelele, i-SANONPIPE ingumhlinzeki wakho othembekile wezixazululo zamapayipi ensimbi e-GB/T 8162. Kungakhathaliseki ukuthi udinga ukuhlinzekwa kwesakhiwo okuvamile, ukuvuselelwa kabusha kwephrojekthi okuphuthumayo noma ukushintshaniswa kwe-ASTM okonga izindleko, siphendula ngokushesha ngesisombululo esifanele.

Xhumana nethimba lethu lokuthengisa namuhla ukuthola izingcaphuno ezinemininingwane, imibiko yokulingana kwebanga noma izinsizakalo zokucubungula ezenziwe ngokwezifiso.
