API 5L X65 PSL1/PSL2Pipa Baja Karbon LSAWdiprodhuksi dening mbentuk piring baja X65 menyang wangun bunder banjur welding lapisan liwat proses welding busur otomatis.Ing produksi sakaAPI 5L X65 PSL1&PSL2Pipa Baja Karbon LSAW, piring kelas X65 dibentuk dening mesin cetakan dadi bentuk bunder banjur dilas liwat welding busur submerged dobel.Proses produksi pipa baja jahitan lurus dilas busur submerged kalebu teknologi JCOE forming, teknologi pengelasan busur submerged coil lan teknologi UOE forming.
Proses pembuatan Longitudinal Submerged-arc Welded (LSAW) Pipa minangka nderek:
Ultrasonik plate probing → pinggiran panggilingan → wis mlengkung → mbentuk → Pra-welding → Internal welding → External welding → Ultrasonik inspeksi → X-ray inspeksi → Expanding → hydraulic test → l.Chamfering → Inspeksi ultrasonik → inspeksi sinar-X → inspeksi partikel magnetik ing ujung tabung
