HABKA SOO SAARKA ALAABTA
Socodka wax soo saarka birta H ee heerka dibadda guud ahaan waa sida soo socota:
Diyaarinta walxaha ceeriin ah: Qalabka ceeriin ee loo sameeyo birta H waa billets bir ah oo caadi ahaan la isticmaalo. Billet-ka birta ah waa in la nadiifiyaa oo la kululeeyaa si uu u shaqeeyo oo uu u qaabeeyo.
Daawaynta kahor: Billet-ka birta ah, ka dib marka la kululeeyo, waxaa la geeyaa warshadda duubista kulul si loogu duubo kulul. Warshadda duubista, duubyada shaqada waxay la xiriiraan FFB meelo badan oo ku teedsan dhererka duubista, billet-kuna si tartiib tartiib ah ayuu u sameeyaa qaab muuqaal ah oo qaab H ah.
Shaqada qabow (ikhtiyaar): Birta qaab-H ah ka dib marka la rogo kulul h waxaa lagu farsameeyay qabow, sida sawir-gacmeedka rogidda qabow, iwm. si loo hagaajiyo saxnaanta iyo tayada dusha sare ee birta qaab-H ah.
Jarida iyo Dhammaystirka: Birta qaabaysan ee H-qaabaysan ee duubista qabow shaqada qabow ee duubista habka wax soo saarka birta nooca H ka dib marka la duubo iyo shaqada qabow ee birta qaabaysan ee H-qaabaysan waxay u baahan tahay in la jaro oo la dhammeeyo iyadoo loo eegayo baahiyaha macaamiisha si loo daboolo cabbirka iyo dhererka shuruudaha gaarka ah.
Daawaynta dusha sare: Dusha sare ee birta H waa nadiif oo miridhku ma daxalaysan yahay. Kormeerka iyo xidhitaanka: Samee kormeer tayo leh oo ku saabsan birta H ee la soo saaray sida tayada muuqaalka, saxnaanta cabbirka, sifooyinka farsamada iwm. Marka la tijaabiyo oo la ansixiyo, waa la xidhaa oo loo geeyaa macaamiisha.

Cabbirrada Joomatari: Dhererka, ballaca, dhererka, dhumucda shabakadda, dhumucda flange-ka iyo cabbirrada kale ee birta qaab-H ah waa inay u hoggaansamaan heerarka khuseeya iyo shuruudaha kala-hormarinta.
Qallooca: Qallooca birta qaabka H waa inuu waafaqsanaadaa heerarka khuseeya iyo shuruudaha kala horraysiinta. Waxaa lagu ogaan karaa iyadoo la cabbirayo in diyaaradaha labada daraf ee birta qaabka H ay is barbar socdaan ama la isticmaalayo mitir qalloocan.
Maroojin: Maroojinka birta qaab H ah waa inuu waafaqsanaadaa heerarka khuseeya iyo shuruudaha kala horraysiinta. Waxaa lagu ogaan karaa iyadoo la cabbirayo in dhinaca birta qaab H ah uu toosan yahay ama uu leeyahay mitir maroojin ah.
Kala leexashada miisaanka: Miisaanka birta qaabka H waa inuu u hoggaansamaa heerarka khuseeya iyo shuruudaha kala horraysiinta. Kala leexashada miisaanka waxaa lagu ogaan karaa miisaan.
Halabuurka Kiimikada: Haddii birta qaab-H ah loo baahan yahay in la alxamo ama si kale loo farsameeyo, halabuurka kiimikadeedu waa inuu u hoggaansamo heerarka khuseeya iyo shuruudaha kala horraysiinta.
Sifooyinka farsamada: Sifooyinka farsamada ee birta qaabka H waa inay u hoggaansamaan heerarka khuseeya iyo shuruudaha kala horraysiinta, oo ay ku jiraan xoogga la riixo, barta wax soo saarka, dheereynta iyo tilmaamayaasha kale.
Tijaabin aan burburin: Haddii birta qaab-dhismeedka H u baahan tahay tijaabin aan burburin, waa in lagu tijaabiyaa iyadoo la raacayo heerarka khuseeya iyo shuruudaha kala-hormarinta si loo hubiyo in tayadeeda gudaha ay wanaagsan tahay.
