I-API 5L ngokuvamile ibhekisela epayipini likalayini-API 5L, ipayipi likalayini elokuthutha uwoyela, isitimu namanzi akhishwe phansi aye embonini kawoyela negesi amabhizinisi ngokusebenzisa ipayipi likalayini.Ipayipi lomugqa lihlanganisa ipayipi elingenamthungo kanye nepayipi lensimbi elishiselwe.Iziphetho zineziphetho eziyisicaba, iziphetho ezinezintambo kanye neziphetho zesokhethi;izindlela zokuxhuma ziyi-welding, uxhumano lwe-coupling, uxhumano lwesokhethi, njll.
| I-PSL | Isimo Sokulethwa | Ibanga lamapayipi |
| I-PSL1 | Njengoba-igoqiwe, ijwayelekile, i-normalizing kwakheka | A |
| Njengoba igoqiwe, i-normalization rolling, i-thermomechanical rolled, i-thermo-mechanical kwakheka, i-normalization kwakheka, i-normalized, i-normalized kanye ne- tempered noma uma kuvunyelwene nge-Q&T SMLS kuphela | B | |
| Njengoba igoqiwe, i-normalization rolling, i-thermomechanical rolled, i-thermo-mechanical kwakheka, i-normalization kwakheka, i-normalized, i-normalized kanye ne- tempered | X42, X46, X52, X56, X60, X65, X70 | |
| I-PSL 2 | Njengoba-igoqiwe | BR, X42R |
| I-normalizing rolling, normalizing kwakheka, normalized or normalized and tempered | BN, X42N, X46N, X52N, X56N, X60N | |
| Icishiwe futhi ithukuthele | BQ, X42Q, X46Q, X56Q, X60Q, X65Q, X70Q, X80Q, X90Q, X100Q | |
| I-Thermomechanical rolled noma i-thermomechanical kwakheka | BM, X42M, X46M, X56M, X60M, X65M, X70M, X80M | |
| I-Thermomechanical igoqwe | X90M, X100M, X120M | |
| Okwanele (R, N, Q noma M) kumamaki e-PSL2, kungokwezinga lensimbi |
1. Inqubo yokukhiqiza eyinhloko yepayipi lensimbi elingenamthungo eligoqiwe elishisayo (inqubo yokuhlola enkulu):
Ukulungiswa kweshubhu elingenalutho nokuhlola→ukushisisa okungenalutho→ukubhoboza→ukugoqeka kweshubhu→ukushisisa kabusha kwensimbi→okulungisiwe (kwehlisiwe) ububanzi→ukwelashwa kokushisa △→ukuqondisa amashubhu okuqediwe→ukuqeda→ukuhlola (okungonakali, okungokomzimba namakhemikhali, ukuhlolwa kwe-Taiwan)→indawo yokugcina impahla
2. Inqubo yokukhiqiza eyinhloko yamapayipi ensimbi angenamthungo (adonswe) abandayo:
Ukulungiselela ibhilidi→ukugcoba ukukha →ukugoqeka okubandayo (umdwebo)→ukwelapha ukushisa→ukuqondisa→ukuqeda→ukuhlola
