API 5L Welded Irin Pipe Ilana iṣelọpọ
Iru 1. Ajija Welded: Ajija welded irin pipesti wa ni ti ṣelọpọ nipasẹ spirally alurinmorin a rinhoho ti irin, lara kan helical pelu. Ilana yii ngbanilaaye fun iṣelọpọ ti awọn paipu iwọn ila opin nla ati nigbagbogbo ni iye owo-doko fun awọn ohun elo kan.
Aso ati itọju:Lati jẹki ipata resistance ati agbara, awọn paipu wọnyi le faragba ọpọlọpọ ibora ati awọn ilana itọju, gẹgẹ bi epoxy bonded fusion (FBE) tabi polyethylene Layer mẹta (3LPE).
Iru 2. Itanna Resistance Welding (ERW):Awọn egbegbe ti adikala irin ti a ṣẹda jẹ kikan nipa lilo resistance itanna. Lẹhinna a lo titẹ lati da awọn egbegbe papọ, ṣiṣẹda weld-ipinle ti o lagbara laisi iwulo fun ohun elo kikun.
Iru 3.Alurinmorin gigun:
Alurinmorin Arc Submerged (SAW): Awọn egbegbe ti paipu ti a ṣe ni a ṣe papọ pẹlu lilo ilana alurinmorin arc ti o wa labẹ omi, eyiti o jẹ pẹlu lilo arc ina ati ṣiṣan granular lati ṣẹda didara giga, weld to lagbara.
Welding Arc Submerged Double (DSAW): Fun awọn paipu to nipon, mejeeji inu ati ita awọn okun ti wa ni welded, aridaju pipe ilaluja ati agbara.
