Ko te API 5L te tikanga mo te paipa raina–API 5L paipa raina, ko te paipa raina ko te kawe i te hinu, te mamaoa me te wai i tangohia mai i te whenua ki nga umanga umanga hinu me te hau ma te paipa raina.Kei roto i te paipa raina he putorino tuitui me te paipa maitai paiherea.Ko nga pito he pito papatahi, he pito miro me nga pito turanga;ko nga tikanga hononga he welding, hono hono, hono turanga, aha atu.
| PSL | Tikanga Tukunga | Koeke paipa |
| PSL1 | Ka rite ki te hurihia, ka whakanoa, ka hangaia | A |
| Ka hurihia, ka huri noa, ka takahurihia te whakamaarama, ka hangaia te wera-miihini, ka hangai te tikanga, te whakahoahoa, te whakamaarama me te weriweri, ki te whakaae ranei Q&T SMLS anake | B | |
| Ka rite ki te hurihia, te whakahurihuri, te takai werawera, te hanga-mahana, te hanga noa, te whakanoa, te whakamaarama me te whakamaarama | X42, X46, X52, X56, X60, X65, X70 | |
| PSL 2 | Ka hurihia | BR, X42R |
| Ko te whakaraerae i te hurihanga, te whakaraerae i te hanga, te whakahoahoa, te whakahoahoa ranei me te whakama | BN, X42N, X46N, X52N, X56N, X60N | |
| Kua tineia me te riri | BQ, X42Q, X46Q, X56Q, X60Q, X65Q, X70Q, X80Q, X90Q, X100Q | |
| Thermomechanical hurihia, thermomechanical ranei i hanga | BM, X42M, X46M, X56M, X60M, X65M, X70M, X80M | |
| Thermmechanical hurihia | X90M, X100M, X120M | |
| Ko te nui (R, N, Q, M ranei) mo nga tohu PSL2, no te karaehe rino |
1. Ko te tukanga whakaputa matua o te putorino maitai wera-hurihia (te mahi tirotiro matua):
Te whakarite me te tirotiro i te ngongo → whakawera parakore ngongo → werohia → te huri ngongo → te whakamahana maitai → te whakatika (whakaitihia) te diameter → te maimoatanga wera △ → te whakatika ngongo kua oti → te whakaoti → te tirotiro (kaore i te kino, te tinana me te matū, te tirotiro o Taiwan) → te whare putunga
2. Ko te tukanga whakaputa matua o nga putorino rino kore-maeke (unu)
Te whakarite pire → whakahinuhinu pickling → hurihuri makariri (tuhi) → maimoatanga wera → whakatikatika → whakaoti → tirotiro
