Guud ahaan, API 5L waxaa loola jeedaa dhuumaha khadka API 5L, kaas oo ka baxsan dhulka saliidda, gaasta, biyaha, ee lagu qaado dhuumaha shidaalka iyo shirkadaha warshadaha gaaska.

Marka loo eego habka wax soo saarka iyo ubaxyada tube ee loo isticmaalo qaabab kala duwan, api 5l waxaa loo qaybin karaa api 5l bir bir ah oo aan fiicneyn iyo tuubo bir ah oo welded ah, oo ka mid ah tirada isticmaalka ee tuubooyinka birta welded ayaa ka badan tuubooyinka birta ah.

Heerka tuubada khadka iyo qaybaha kiimikada

API 5L waxa loo qaybin karaa API 5L PSL 1 iyo API 5L PSL 2, oo ay ku jiraan API 5L PSL 1 heerka qaybahana waa: A, B, x42, x46, x52, x56, x60, x65, x70, API 5L PSL 2 level qaybtuna waa B, x42, x46, x52, x56, x60, x65, xx70, x80.Markasta oo ay sare u kacdo sifooyinka farsamada ee xooggan.

Codsiga: loo isticmaalo warshadaha saliidda iyo gaaska, gaaska, biyaha, gaadiidka saliidda.

API SPEC 5L Pipe Line

API SPEC 5L geeddi-socodka wax-soo-saarka xariiqda wuxuu u qaybsan yahay tuubo bir ah oo aan kala go 'lahayn, tuubbada birta ERW, dhuumaha alxanka hoostiisa.Laakiin isticmaalka ugu weyn ee tuubada birta ah ee aan fiicneyn (The Seamless), tollayn toosan oo caabbinta sare leh ee tuubada birta alxanka (Electric-Resistance Arc Welding, oo loo soo gaabiyo ERW), LSAW (Longigudinally Submerged Arc Welding short LSAW), spiral submerged arc tube welded (Spirally) Alxanka Arc hoostiisa, oo ka gaaban SSAW) afar.

Dhuumaha LSAW waxay u qaybsan yihiin UO (qaabka samaynta UOE), RB (RBE), JCO (JCOE) iyo noocyo kale.Saxanka birta ah ee qaabaynta waxa lagu cadaadi doonaa U-qaabeeya, ka dibna lagu cadaadi doono O-, ka dibna gudaha iyo dibaddaba waxa la quusiyaa alxanka arc, ka dib alxanka, sida caadiga ah dhamaadka dhererka buuxa ee balaadhinta (Fidinta) loo yaqaan UOE tubbada alxanka leh, aan fidin ee loo yaqaan dhuumaha UO.Qalloocinta saxannada birta ah ee cadaadiska (Roll Bending), ka dibna gudaha iyo dibaddaba waxay hoos u galeen alxanka arc, ka dib alxanka, ballaarinta tuubada RBE, ama aan ballaarin tuubada RB.Saxanka qaabaynta iyadoo la raacayo nooca JOC-dalabka balaadhinta tuubada JCOE ama aan la balaadhinaynin tuubada JCO alxanka ka dib.Tuubooyinka LSAW ee kore, isticmaalka guud ee UOE.Tuubbada alxanka iska caabbinta soo noqnoqda sare ee embriyaha ERW iyada oo loo marayo saamaynta maqaarka iyo saamaynta u dhawaanshaha ee hadda-sare ee cidhifka dhalaalka, ka dibna tuuji rollers hoos alxanka cadaadiska, kaas oo lagu garto ma laha biraha buuxinta dibadda, aagga kuleylka saameeya, sare waxtarka wax soo saarka.Dhuumaha tolitaanka Spiral SSAW ee tuubada khadka fog waxay leedahay taariikh dheer, dhuumaha Shiinaha ayaa inta badan la isticmaalaa.
