okeereErogba Irin Pipe,China Irin Pipe,Kekere Erogba Irin Pipe,welded oniho, lati China. Ile-iṣẹ wa ṣe amọja ni okeere ti awọn paipu irin welded ati awọn paipu irin alailẹgbẹ. Ẹgbẹẹgbẹrun awọn toonu ti awọn paipu irin welded ti wa ni okeere ni gbogbo ọdun. Awọn paipu welded ti a maa n gbejade nigbagbogbo ti pin si LSAW ati SSAW. Ṣe o mọ awọn iyatọ laarin LSAW Pipe ati SSAW Pipe?
Pipe LSAW (Longitudinal Submerged Arc-Welding Pipe), ti a tun pe ni paipu SAWL. O n mu awo irin naa bi ohun elo aise, ṣe apẹrẹ nipasẹ ẹrọ idọgba, lẹhinna ṣe alurinmorin aaki submerged ti apa meji. Nipasẹ ilana yii paipu irin LSAW yoo gba ductility ti o dara julọ, lile weld, iṣọkan, ṣiṣu ati lilẹ nla.
Iwọn ila opin paipu LSAW tobi ju ERW lọ, deede lati inch 16 si 60 inch, 406mm si 1500mm. Awọn iṣẹ ṣiṣe ti o dara lori resistance titẹ giga, ati resistance ipata iwọn otutu kekere.
O ti wa ni lilo pupọ ni awọn opo gigun ti epo ati gaasi, pataki ti o nilo iwọn ila opin nla ati paipu ogiri ti o nipọn pẹlu agbara giga ati ijinna pipẹ. Nibayi ni ikole ti eto ti o nilo agbara lile, itọju omi, ile-iṣẹ igbona, ile afara, bbl Gẹgẹbi awọn alaye API, paipu LSAW (Pipu SAWL tabi paipu JCOE) jẹ apẹrẹ pataki ni epo ati gbigbe gaasi nla, ni awọn ọran ti pipelines kọja ilu, okun, ati agbegbe ilu. Iwọnyi ni awọn agbegbe 1 ati kilasi 2.
SSAW Pipe (Ajija Submerged Arc-Welding Pipe), tun npe ni HSAW paipu (Helical SAW), alurinmorin apẹrẹ bi a helix. O nlo imọ-ẹrọ alurinmorin kanna ti Arc-Welding Submerged pẹlu paipu LSAW. O yatọ si SSAW paipu ti wa ni ajija welded ibi ti LSAW ti wa ni gigun welded. Ilana iṣelọpọ ti n sẹsẹ okun irin, lati jẹ ki itọsọna yiyi ni igun kan pẹlu itọsọna ti ile-iṣẹ paipu, ṣiṣe ati alurinmorin, nitorinaa okun wiwọ wa ni laini ajija.
Iwọn iwọn ila opin SSAW jẹ lati 20 inch si 100 inch, 406 mm si 2540 mm. Apakan anfani ni a le gba iwọn ila opin ti o yatọ si ti awọn paipu SSAW pẹlu iwọn kanna ti okun irin, ohun elo jakejado wa fun ohun elo aise. irin rinhoho, ati alurinmorin pelu yẹ ki o yago fun awọn jc wahala, ti o dara išẹ lati ru wahala.
Alailanfani jẹ iwọn ti ara ti ko dara, gigun gigun alurinmorin gun ju ipari paipu lọ, rọrun lati fa awọn abawọn ti awọn dojuijako, iho afẹfẹ, ifisi cinder, alurinmorin apa, agbara alurinmorin ni ipo fifa.
Fun awọn eto opo gigun ti epo ati gaasi, ṣugbọn ni sipesifikesonu apẹrẹ epo, paipu SSAW / paipu HSAW le ṣee lo ni kilasi 3 ati awọn agbegbe 4 kilasi. Eto ikole, gbigbe omi ati itọju omi idoti, ile-iṣẹ igbona, awọn ile ati bẹbẹ lọ.
