API 5L X52 Classification
Ngokuxhomekeke kwinqanaba le-PSL kunye nemeko yokuhanjiswa, i-X52 ingahlelwa ngolu hlobo lulandelayo:
PSL1: X52;
PSL2:X52N okanye L360N;X52Q okanye L360Q;X52M okanye L360M.
Kwi-PSL2, ileta yesimamva sibhekiselele kuhlobo lonyango lobushushu ekufuneka ifakwe kulo phambi kokunikezelwa kokugqibela.Ungayibona iiimeko zokuhanjiswangezantsi ngeenkcukacha ezithe vetshe.
Imiqathango yokuhanjiswa
Umbandela Wokuqalisa
Iingots, blooms, billets, coils, okanye plates.
Ngombhobho we-PSL 2, intsimbi iya kubulawa kwaye yenziwe ngokwendlela yokutya okuziinkozo.
Ikhoyili okanye ipleyiti esetyenziselwa ukwenziwa kombhobho we-PSL 2 ayiyi kuba naziphi na iiwelds zokulungisa.
API 5L X52 Inkqubo yokuVelisa
Iityhubhu ze-X52 zinokuveliswa kusetyenziswa iinkqubo ezahlukeneyo zokwenziwa kwetyhubhu ukuhlangabezana neemfuno zobunjineli ezahlukeneyo.
Ukufumana ngakumbi malunga nentsingiselo yesifinyezo seNkqubo yokuVelisa,Cofa apha.
SAWLsesona sisombululo siphezuluububanzi obukhulu, obungqingqwaimibhobho yentsimbi.
Amagama "SAWL"kwaye"LSAW" zombini zibhekisela kwi-Longitudinal Submerged Arc Welded, kodwa zibhekiswa ngokuhlukileyo kwimimandla eyahlukeneyo. Ngokwahlukileyo, igama elithi "LSAW" lisetyenziswa kakhulu kwishishini.
Umbhobho we-LSAW unokudityaniswa kabini ngenxa yokunciphisa izixhobo ekuveliseni umbhobho wobubanzi obukhulu, kwaye i-welds kufuneka ibe malunga ne-180 ° ngaphandle.
Iindidi zokuphela kombhobho we-API 5L X52
PSL1 Isiphelo sombhobho wentsimbi: Isiphelo sentsimbi okanye isiphelo esicacileyo;
PSL2 Isiphelo sombhobho wentsimbi: Isiphelo esingenanto;
Kwiziphelo zombhobho ocacileyokufuneka kulandelwe ezi mfuno zilandelayo:
Ubuso besiphelo se-t ≤ 3.2 mm (0.125 in) umbhobho wokuphela ocacileyo uya kunqunyulwa isikwere.
Iityhubhu ezipheleleyo ezine-t> 3.2 mm (0.125 in) ziya kugqunywa ukuze zidibanise.I-angle ye-bevel kufuneka ibe yi-30-35 ° kunye nobubanzi bengcambu yobuso be-bevel kufuneka ibe ngu-0.8 - 2.4 mm (0.031 - 0.093 in).
I-API 5L X52 Ukwakhiwa kweMichiza
Ukwakhiwa kweekhemikhali ze-PSL1 kunye ne-PSL2 ipayipi yensimbi t> 25.0 mm (0.984 in) iya kugqitywa ngesivumelwano.
Ukuqulunqwa kweMichiza ye-PSL 1 Ipayipi ene-t ≤ 25.0 mm (0.984 in.)
