Api 5lGuud ahaan waxaa loola jeedaa tuubada birta ee dhuumaha (tuubada tuubbada) ee fulinta heerka caadiga ah, dhuumahatuubbada birtaoo ay ku jiraan tuubbada birta ee xasaasiyadeed iyo tuubbada birta ee weldes ah laba qaybood. Waqtigan xaadirka ah ee dhuumaha saliida ee aan si caadi ah u isticmaalnay nooca birta ee dhuuban ee birta ahSSAW), oo ah xaraashka toosan ee balooggeedaLsow), iska caabbinta tuubada alxanka (Erw), tuubbada birta ahguud ahaan waxaa loo isticmaalaa dhexroor tuubbada tuubbada ka yar 152mm.
Heerka Qaranka ee GB / T 9711-2011-2011 Pipe Steel Nidaamka Gaadiidka ee dhuumaha ee Warshadaha saliida iyo gaaska ayaa lagu soo ururiyaa iyadoo la raacayo API 5L.
GB / T 9711-2011 waxay cadeyneysaa shuruudaha wax soo saarka ee tuubooyinka birta aan fiicnayn ee laba heerar qeex ah oo ah shaashadda (PSL1 iyo PSL1) ee nidaamyada gaadiidka dhuumaha ee batroolka iyo gaaska. Sidaa darteed, heerka caadiga ah wuxuu quseeyaa kaliya tuubooyinka birta aan la tolay iyo tuubooyinka birta ee gaaska ah ee gaadiidka saliida iyo gaaska, oo laguma dabaqi karo tuubooyinka birta.
Fasalada Birta
The steel grades of raw materials for steel pipes of this API 5L standard are GR.B, X42, X46, X52, X56, X60, X70, X80, etc. The steel grades of steel pipes are different, and the requirements for raw materials Waxsoosaarkuna sidoo kale waa kala duwan yihiin, laakiin kaarboon u dhigma ee u dhexeeya fasalada birta ee kaladuwan ayaa si adag loo xakameeyaa.
Heerarka Tayada
Heerka API 5L Standard Standard, heerarka tayada leh (ama shuruudaha) ee tuubbada birta ah ayaa loo qaybiyaa PSL1 iyo PSL2. PSL waa soo gaabinta heerka qeexitaanka alaabada.
PSL1 waxay bixisaa heer guud oo shuruudaha tayada tayada ah; PSL2 waxay ku kordhisaa shuruudaha qasabka ah ee isku-darka kiimikada, oo la xayuubiyey waxyaabaha adag, xoogga xoogga, iyo ndes dheeraad ah.
