Sida laga soo xigtay Heerka API 5L, tuubooyinkayaga qunyar-socodka ah ee is-wareejinta ayaa laga heli karaa moodooyin kala duwan, oo ay ku jiraan api 5l x42, api 5l x52 iyo api 5l 5l 5l 5l 5l 5l 5l 5l 5l 5l 5l 3l x60. Moodooyinkaani waxay matalaan xoogga dhalidda hoose ee tuubbada, iyagoo ku siinaya faham dhameystiran oo ku saabsan wax qabadkeeda. Haddii aad u baahan tahay inaad tuubiso mashruuc yar ama hawlgal ballaaran, moodooyinkayaga kala duwan ee kala duwan ayaa buuxin kara baahiyahaaga oo dhan.

API 5L X42 Moodooyinka waxaa lagu yaqaanaa dowladnimadooda heersare ah iyo xoog sare. Waxay ku habboon tahay mashaariicda u baahan ganaaxa gaaska dabiiciga ah, saliida, iyo dareeraha kale. Qaabkan ayaa bixiya iska caabbinta ka-reeban oo ah iska caabbinta iyo astaamaha farsamada ee cajiibka ah si loo gaarsiiyo wax qabad dheer oo waara, taas oo lagu hubinayo in la sii daayo hagaajinta nidaamka saliida iyo gaaska.

Mashaariicda u baahan waxqabadka sare, api 5l model model waa doorashada ugu fiican. Dhuunta waxaa loogu talagalay in lagu hor tago cadaadisyada sareeya iyo heerkul aad u daran, hubinta gaadiidka saliidda iyo gaaska iyo gaaska ee hufan. Awooda ugu sarreysa waxay u oggolaaneysaa inay wax ka qabtaan xaaladaha adag, hubinta in siman, socodka aan kala go 'lahayn.

Qaabka API 5l X60 wuxuu qaataa waxqabadka heerka xiga. Iyada oo ay la jirto awooddeeda wax soo saarka gaarka ah iyo adkeynta adag, tuubbada ayaa ku habboon in la isticmaalo xitaa jawiga ugu baahi badan. Waxaa loogu talagalay in lagu maareeyo mashaariicda waaweyn ee u baahan gaadiid aad u badan oo saliid iyo gaas ah.

Xulashada biibiilaha khadkayaga 5l 5L ah micnaheedu waa maalgashiga badeecada dammaanad ka ah tayada sare iyo waxqabadka. Balanqaadkeena heer sare ee heer sare ah ayaa ku muuqda dhinac kasta oo dhuumaha, laga bilaabo dhisme aan kala go 'lahayn oo ah awooddeena aan kula kulanno oo ka badanno heerarka caalamiga ah. Iyada oo xoogga sare iyo cimriga ah, badeecadan waxay xaqiijineysaa meel aamin ah oo hufan oo saliid iyo gaas ah, iyagoo ku siinaya nabadgelyo maskaxda ah.

Marka la soo gaabiyo, tuubada khadka tooska ah ee API 5L 5L 5l ayaa noqotay xulashada ugu dambeysa ee dhuumaha saliida iyo gaaska oo leh moodallo hodan ah iyo tayada wanaagsan. By alxanka alxanka ee wareega, waxay bixisaa awood aan waxtar lahayn iyo cimri dherer. Haddii aad u baahan tahay tuubbo-yar ama mashruuc weyn, tuubkeenna birta ee loo yaqaan 'steel based' oo la soo saaray aaladda API 5l waxay dammaanad qaadaan waxqabadka la isku halleyn karo. Maalgeliso tuubadayada khadkayaga 5l 5l oo aad la kulanto farqiga u dhexeeya tayada iyo waxqabadka.
