    Marka loo eego halbeegga API 5L, tuubooyinkeena alxanka leh ayaa lagu heli karaa noocyo kala duwan, oo ay ku jiraan API 5L X42, API 5L X52 iyo API 5L X60.Moodooyinkani waxay matalaan awoodda wax-soo-saarka hooseeya ee tuubada, iyagoo ku siinaya faham dhammaystiran oo ku saabsan waxqabadkeeda.Haddii aad u baahan tahay tuubbooyinka mashruuc yar ama hawlgal ballaadhan, noocyada kala duwan ee noocyadayadu waxay dabooli karaan dhammaan baahiyahaaga.

    Alxanka Arc ee Helicalka ah

    Moodooyinka API 5L X42 waxaa lagu yaqaannaa alxanka wanaagsan iyo xoogga sare.Waxay ku habboon tahay mashaariicda u baahan gaadiidka gaaska dabiiciga ah, saliidda, iyo dareerayaasha kale.Qaabkani waxa uu bixiyaa iska caabin daxalka oo gaar ah iyo siyaalo farsamo oo cajiib ah si loo bixiyo waxqabad waara, hubinta daacadnimada hababka gudbinta saliidda iyo gaaska.

    Mashaariicda u baahan waxqabad sare, qaabka API 5L X52 ayaa ah doorashada ugu fiican.Dhuumaha waxaa loogu talagalay in ay u adkeyso cadaadiska sare iyo heerkulka aad u daran, hubinta la isku halayn karo oo hufan gaadiidka saliidda iyo gaaska.Awooddeeda sare waxay u oggolaaneysaa inay xakameyso xaaladaha adag, hubinta socodka siman, aan kala go'a lahayn.

    Qaabka API 5L X60 wuxuu u qaadaa waxqabadka heerka xiga.Iyada oo leh xoog wax soo saarkeeda gaarka ah iyo adkeynta la xoojiyey, tuubada ayaa ku habboon in loo isticmaalo xitaa meelaha ugu baahida badan.Waxa loogu talo galay in lagu qabto mashaariic waaweyn oo u baahan in la raro shidaal iyo gaas tiro badan.

    Doorashada dhuumaha khadka API 5L macnaheedu waa maalgelinta badeecad dammaanad qaadaysa tayada iyo waxqabadka sare.Waxaa naga go'an in aan heer sare ka gaarno dhinac kasta oo ka mid ah dhuumahayaga, laga bilaabo dhismaha aan kala go 'lahayn ilaa awoodda aan u leenahay inaan buuxino oo dhaafno heerarka caalamiga ah.Awoodeeda sare iyo cimri dhererkeeda, badeecadani waxay hubisaa gaadiidka badbaadada iyo waxtarka leh ee saliidda iyo gaaska, oo ku siinaya xasilloonida maskaxda.

    Marka la soo koobo, dhuumaha khadka API 5L ayaa noqday doorashada ugu dambeysa ee dhuumaha gudbinta saliidda iyo gaaska oo leh moodooyinkeeda hodanka ah iyo tayada wanaagsan.Alxanka dhulka hoostiisa ku jira ee spiral, waxa ay siisaa xoog iyo adkaysi aan la barbar dhigi karin.Haddii aad u baahan tahay tuubo mashruuc yar ama weyn, tuubadayada birta alxanka leh ee xayndaabka ah ee lagu sameeyay heerarka API 5L waxay dammaanad qaadaysaa waxqabad la isku halayn karo.Maalgelinta dhuumaha khadka API 5L oo khibrad kala duwanaanshaha tayada iyo waxqabadka.
