API 5L X65 Classification
Ngokuxhomekeke kwinqanaba le-PSL kunye nemeko yokuhanjiswa, i-X65 ingahlelwa ngolu hlobo lulandelayo:
PSL1: X65 (L450);
PSL2: X65Q (L450Q) kunye ne-X65M (L450M);
Ukuze uhlangabezane neemeko ezinzima ze-offshore (O) kunye neendawo zenkonzo ezimuncu (S), umgangatho we-API 5L PSL2 uneemfuno ezikhethekileyo kuzo zombini iindawo.Ezi mfuno zibonakaliswa ngokongezwa kweleta ethile kwibakala lombhobho.
Iinkonzo zaselunxwemeni PSL2 umbhobho:X65QO (l450QO) okanye X65MO (L450MO);
Umbhobho wePSL2 wenkonzo emuncu:I-X65QS (L450QS) okanye i-X65MS (L450MS).
Imiqathango yokuhanjiswa
Intsingiselo ye-Q kunye ne-M
KubaSAW(I-Arc entywilweyo iWelded) okanyeINKOMAZI(I-Combination Welded Pipe), i-Q kunye ne-M kwisimo sokuhanjiswa kwe-API 5L PSL2 ihambelana nezi nkqubo zokuvelisa zilandelayo.
API 5L X65 Inkqubo yokuVelisa
X65imibhobho inokuveliswa ngeendlela ezahlukeneyo zokuvelisa ukuze ihambelane noluhlu olubanzi lwezicelo zobunjineli.
SAWL(i-LSAW) ilungele ukuveliswa kweetyhubhu ezinobubanzi obukhulu, ezinodonga olungqingqwa kunye nobubanzi obungaphezulu kwe-660 mm, ngokukodwa kwinqanaba lexabiso apho libonelela ngexabiso leendleko kwiityhubhu ezingenamthungo.
Iindidi zokuphela kombhobho we-API 5L X65
PSL1 Isiphelo sombhobho wentsimbi: Isiphelo sentsimbi okanye isiphelo esicacileyo;
PSL2 Isiphelo sombhobho wentsimbi: Isiphelo esingenanto;
Kwiziphelo zombhobho ocacileyokufuneka kulandelwe ezi mfuno zilandelayo:
