Tuubbo Cinjir ah oo Dhoobo ah
Tuubada cinjirka ah ee dhoobada lagu dahaadhay ayaa la isticmaalayaa xaalad aad u daran halkaas oo tuubada cinjirka ah ee caadiga ah ee aan dahaadhka lahayn ay u baahan tahay beddel joogto ah. Sidoo kale, tuubada cinjirka ah ee dhoobada lagu dahaadhay waxaa lagu rakibi karaa nooc ka mid ah mashiinnada gariirka ama qalab aan istaagin. Waxay kordhin kartaa xulashada injineerada iyadoo si ballaaran loo adeegsanayo rakibidda iyo hawlgalka.
Astaamaha
1. Xiro iska caabin
Iska caabbinta xirashada tuubada cinjirka ah ee dhoobada lagu dahaadhay ayaa 10 jeer ka badan tan tuubada birta caadiga ah, waana 20 jeer ka badan tan tuubada caadiga ah;
2. Iska caabbinta daxalka
Cinjirka dhoobada iyo kan tayada sare leh ee ka hortagga daxalka ayaa iska caabin kara dhammaan xaaladaha adag;
3. Iska caabbinta saameynta
Saamaynta xoogga dhoobada daqiiqadda ay ku leedahay kaydka caagga ah iyo nuugista, sidaas darteed tuubada caagga dhoobada ah ee SHP-CR ee u adkaysta xirashada walxaha waaweyn waxay saameyn ku yeelanaysaa;
4. Miisaan fudud
Miisaanku waa 30% oo keliya tuubooyinka birta ah;
5. Dabacsanaan
Naqshadeynta dhoobada dhululubada ah ee ku jirta caagga iyo habaynta saxda ah waxay ka dhigaysaa tuubada mid dabacsanaan wanaagsan leh, qaloocinta xagasha weyn saameyn kuma yeelan doonto dhoobada;
6. Rakibaad ku habboon oo degdeg ah
Ku dar isku xirka flange go'an, flange firfircoon, boolal, ama isku xire degdeg ah.
Tilmaamaha Farsamada
1. Cabbirrada dhexroorka laga bilaabo 1 inji ilaa 24 inji
2. Dhererka ilaa 20 mitir
3. Cadaadiska ugu badan ee hawlgalka ee 150 Psi
4. Heerkulka ugu badan ee hawlgalka waa 250˚F
