Si sax ah u qeexidda cabbirka tuubada birta ah waxay u baahan tahay inay ku jirto dhowr xuduudood oo muhiim ah:
Dhexroorka Dibadda (OD)
Dhexroorka dibadda ee tuubada birta ah, oo badanaa lagu muujiyo dhexroorka magacaaban (DN) ama cabbirka tuubada magacaaban (NPS).
Cabbirka Tuubada Magacaaban (NPS) iyo Dhexroorka Magacaaban (DN)
NPS waa cabbirka magacaaban oo ku salaysan inji, halka DN ay tahay dhexroorka magacaaban ee milimitir. Xiriirka beddelka waa mid fudud: qiimaha DN wuxuu la mid yahay qiimaha NPS oo lagu dhuftay 25.4 (mm/inch) si loo soo koobo natiijada.
Dhab ahaantii, iswaafajinta u dhaxaysa heerarka NPS iyo DN waxay ku salaysan tahay jaantusyada cabbirka caadiga ah ee la aasaasay.
Dhumucda Darbiga (WT)
Dhumucda derbiga tuubada. Tuubada cabbirka caadiga ah, dhumucda derbiga waxaa badanaa lala xiriiriyaa Jadwalka tuubada, tusaale ahaan Jadwalka 40 ama Jadwalka 80, halkaas oo qiimayaasha waaweyn ay tilmaamayaan derbiyo qaro weyn.
Dhererka
Dhererka tuubo bir ah, oo la hagaajin karo ama aan kala sooc lahayn, iyadoo ku xiran shuruudaha wax soo saarka iyo codsiga. Dhererka caadiga ah waa 6 mitir iyo 12 mitir.
Alaab
Heerarka agabka iyo darajooyinka tuubooyinka birta ah, sida ASTM A106 Fasalka B, API 5L Fasalka B, iwm. Heerarkani waxay qeexayaan halabuurka kiimikada iyo sifooyinka jireed ee tuubada.
Heerarka
Heerarka cabbirka ee tuubooyinka kaarboonka iyo birta aan daxalka lahayn waxay inta badan raacaan ASME B36.10M (birta kaarboonka iyo birta aan daxalka lahayn) iyo B36.19M (birta aan daxalka lahayn).
Miisaska Cabbirka Tuubada iyo Miisaska Heerka Miisaanka (WGT)
Bixi hab la siman oo lagu qeexo dhumucda darbiga tuubooyinka iyadoo la raacayo Jadwalo kala duwan, iyo sidoo kale kala soocidda darajooyinka miisaanka sida STD, XS, XXS, iyo kuwa kale.
Dhumucda derbiga ee tuubo ayaa si toos ah u saamaysa cabbirka gudaha iyo miisaanka tuubada. Dhumucda derbiga ayaa muhiim ah sababtoo ah waxay go'aamisaa xaddiga cadaadiska gudaha ee tuubooyinku u adkeysan karaan.
Lambarka jadwalka
Hab lagu tilmaamayo dhumucda derbiga ee tuubada, sida caadiga ah Jadwalka 40 iyo 80, waxa uu tilmaamayaa dhumucda derbiga caadiga ah iyo tan la xoojiyay ee tuubada ee dhexroorka dibadda ee la bixiyay.
Xisaabinta qiyaasta ah ee lambarka jadwalka waa sidan soo socota:
Maadaama ay awood u leeyihiin inay u adkeystaan cadaadisyada caadiga ah awgeed, tuubooyinka birta ah ee Jadwalka 40 iyo Jadwalka 80 ayaa si caadi ah loogu baahan yahay warshado kala duwan. Maadaama tuubooyinkan loogu talagalay inay u adkeystaan cadaadisyada sare, badanaa waxaa looga baahan yahay tiro badan si loo daboolo baahiyaha warshadaha kala duwan.
