Ifekthri Eshibhile yase-China Ikhwalithi Ephakeme Amapayipi Ashiselwe Insimbi Yensimbi Eqondile Eqondile
Uhlolojikelele
"Lawula izinga ngemininingwane, bonisa amandla ngekhwalithi". Ibhizinisi lethu lizamile ukusungula izisebenzi ezisebenza kahle kakhulu nezizinzile futhi lahlola inqubo yokulawula ikhwalithi enhle ye-Straight Carbon Steel Welded Pipes. Ikhwalithi enhle ubukhona befektri, ukugxila ekufuneni kwekhasimende kuwumthombo wokusinda nokuthuthuka kwenkampani, Sinamathela ekuthembekeni nasekusebenzeni kokholo oluphakeme, sibheke phambili ekufikeni kwakho!
Ukuze uthole ipayipi le-carbon steel elishiselwe, kunesidingo sobuchwepheshe obu-2 obuyinhloko ukuthi i-ERW(i-electric resistance weld) kanye ne-SAW (i-submerge arc weld). Amapayipi asebenzisa lobu buchwepheshe womabili asetshenziselwa ikakhulukazi imboni ye-petroleum yokuthutha uwoyela negesi, kodwa wonke anenzuzo yawo, ngakho-ke ukusetshenziswa kuhlukile.
Ipayipi le-ERW lenziwe nge-steel plate, kunomthungo owodwa kuphela oshiselwe, futhi ngenxa yokuthi ulayini oshiselwe wepayipi le-ERW uphuma epayipini likamama, alidingi i-solder flux, ngakho-ke impahla yokukhanda yinhle kakhulu. Futhi ngenxa yezimpawu zayo zokusebenza kahle kakhulu kokukhiqiza, izindleko eziphansi, ukonga impahla, kanye ne-automation elula, uma kuqhathaniswa nepayipi le-SAW, ipayipi le-ERW liyipayipi lensimbi elinomkhiqizo othuthukisiwe osebenza kahle, ikhwalithi eholayo kanye nokusebenza ngokonga okulinganiselwe emkhakheni wokugcinwa kukawoyela negesi. nezokuthutha. Ikakhulukazi landela ukukhula kobuchwepheshe, ikhwalithi uma ulayini oshiselwe iba ngcono kakhulu, ngokusebenzisa ubuchwepheshe obusha, inhloso iwukuqeda ukucindezeleka, ukuthambisa nokucwenga isakhiwo, futhi kuthuthukiswe izici ezibanzi zemishini yendawo ethintekile yokushisela. Lolu hlobo lwepayipi lwe-ERW alukwazi ukuhlukaniswa kuphela i-weld, kodwa futhi i-coefficient ye-weld ifinyelela ku-1, eqaphela ukuhambisana kwesakhiwo sendawo ye-weld ne-base material.
Ubuningi bamanje bezobuchwepheshe be-SAW buphezulu kakhulu, futhi isendlalelo se-flux sivimbela ukulahlekelwa kokushisa okusheshayo futhi sigxilise endaweni ye-soldering. I-arc welding engaphansi kwamanzi inekhwalithi ephezulu ye-weld seam, ukusebenza kahle kokukhiqiza okuphezulu, akukho ukukhanya kwe-arc kanye nentuthu encane. Amapayipi ensimbi afakwe ngaphansi kwe-arc ashiselwe asetshenziswa kakhulu emikhunjini yokucindezela, ukufakwa kwamapayipi, imishayo, amakholomu, uketshezi olunomfutho ophansi, kanye namaphrojekthi wesakhiwo sensimbi. Kodwa embonini kaphethiloli yezwe elithuthukile, ipayipi le-SAW alivunyelwe ukungena ngoba umkhawulo walo, e-China ipayipi le-SAW kuphela elisavunyelwe embonini ye-petroleum enomkhawulo.
Ikhwalithi enhle nentengo ephusile" yizimiso zethu zebhizinisi. Uma unentshisekelo ngemikhiqizo yethu nezisombululo noma unemibuzo, qiniseka ukuthi uzizwa ukhululekile ukusithinta. Sithemba ukusungula ubudlelwano bokubambisana nawe maduze nje.
Isicelo
Isetshenziselwa Ikakhulukazi izingxenye zamandla nengcindezi, futhi ngenjongo evamile yamapayipi omusi, amanzi, igesi nomoya.
