I-API 5L ngokuqhelekileyo ibhekisela kumbhobho womgca we-API 5L, umbhobho womgca kukuthutha i-oyile, umphunga kunye namanzi akhutshwe emhlabeni ukuya kumashishini oshishino lwe-oyile kunye negesi ngokusebenzisa umbhobho womgca.Umbhobho womgca uquka umbhobho ongenamthungo kunye nombhobho wensimbi odibeneyo.Iziphelo zineziphelo ezisicaba, iziphelo ezinemisonto kunye neziphelo zesiseko;iindlela zokudibanisa zi-welding, ukudibanisa ukudibanisa, ukudibanisa i-socket, njl.
| PSL | Unikezelo lwemeko | Ibakala lombhobho |
| PSL1 | Njenge-rolled, normalized, normalizing yakha | A |
| Njenge-rolled, normalizing rolled, thermomechanical rolled, thermo-mechanical made, normalizing ebunjwe, iqhelekile, iqhelekile kwaye inomsindo okanye ukuba kuvunyelwene Q&T SMLS kuphela. | B | |
| Njengoko i-rolled, i-normalizing rolled, i-thermomechanical rolled, i-thermo-mechanical yenziwa, i-normalizing yakha, i-normalized, i-normalized kwaye inomsindo | X42, X46, X52, X56, X60, X65, X70 | |
| PSL 2 | Njengoko-iqengqiwe | BR, X42R |
| I-normalizing rolled, normalizing yakha, i-normalizing okanye i-normalized kunye ne-tereded | BN, X42N, X46N, X52N, X56N, X60N | |
| Ucinywe kwaye unomsindo | BQ, X42Q, X46Q, X56Q, X60Q, X65Q, X70Q, X80Q, X90Q, X100Q | |
| I-Thermomechanical rolled okanye i-thermomechanical yenziwe | BM, X42M, X46M, X56M, X60M, X65M, X70M, X80M | |
| Thermomechanical rolled | X90M, X100M, X120M | |
| Ukwanela (R, N, Q okanye M) kumabakala e-PSL2, ngowebakala lentsimbi |
1. Inkqubo ephambili yokuvelisa umbhobho wentsimbi engenamthungo eshushu-eqengqelekayo (inkqubo yokuhlola ephambili):
Ukulungiswa kwetyhubhu engenanto kunye nokuhlolwa→ityhubhu engenanto yokufudumeza→ukugqobhoza→ityhubhu eqengqelekayo→ukufudumeza kwakhona kwentsimbi→okuzinzileyo (kwehlisiwe) ubukhulu→unyango lobushushu △→ukulungiswa kwetyhubhu egqityiweyo→ukugqiba→ukuhlola (engonakalisiyo, umzimba kunye neekhemikhali, uhlolo lwaseTaiwan)→indawo yokugcina impahla
2. Eyona nkqubo yokuvelisa imibhobho yentsimbi epholileyo eqengqelekayo (etsaliweyo) engenamthungo:
Ukulungiswa kwebhilethi→ukuchopha ukuthambisa→ukuqengqeleka okubandayo(umzobo)→unyango lobushushu→ukulungisa→ukugqiba→ukuhlola
