JIS G3429 STH12 STH22 34Crmo4 Tuubbada Birta ee Silinder CNG
Faahfaahinta Alaabta
Tuubbada gaasta cadaadiska sare waa nooc ka mid ah tuubo bir ah oo aan bir lahayn, oo sida badan loo yaqaan tuubada birta ah ee gaaska gaaska, oo si ballaaran loogu isticmaalo dhammaan noocyada taangiyada markabka cadaadiska sare, iyo sidoo kale dhululubada gaaska warshadaha, dhululubada dabka, gawaarida CNG dhululubada, gawaarida c.
Waxyaabaha ugu muhiimsan ee tuubada dhululubada gaaska waa: 38Mn6, 30CrMo4, Kooxda, 4130X, Fasalka C, Fasalka E, STH11, STH12, STH21, STH22.
Heerka JIS G3429 wuxuu cayimay tuubooyinka birta ah ee birta ah ee aan sinnayn ee loo isticmaalo soo saarista dhululubada gaaska birta ah ee bilaa-xarafka ah.Tuubooyinka JIS 3429 waa in loo kala saaraa 5 darajooyin, tubbada STH22 ee darajada waa dhexdhexaad iyo nooc kaarboon-molybdenum ah oo dhexdhexaad ah oo hooseeya oo loo isticmaalo weelka cadaadiska ee lagu sameeyo hababka wax soo saarka ee aan sinnayn.Deegaanka adeegga ee dhululubada gaasta cadaadiska sare ayaa soo bandhigay shuruudaha sare ee waxqabadka tuubada birta,
Maaddada STH22 waxaa si ballaaran loo isticmaalaa sida walxo dhululubo ah oo ku jira jawi shaqo oo sarreeya sababtoo ah xooggeeda sare ee heerkulka sare iyo xoogga gurguurta ee aad u fiican.
34CrMo4 waa bir qaabdhismeed alloy ah oo leh dulqaad sare iyo xoog gurguurta heerkul sare, waxay la mid tahay heerka STH22 ee birta ah.Waxaa inta badan loo isticmaalaa wax soo saarka dhululubada ama qaybaha qaabdhismeedka ka hoos shaqeeya culays sare sida qaybaha gudbinta baabuurta iyo matoorada;turbine-generator rotor, spindle, usheeda dhexe load culus, qaybaha waaweyn ee qaybaha, marsho jiid jiid, supercharger marsho gudbinta, usheeda dambe, usha isku xidha iyo xajin guga oo leh culays weyn, sidoo kale waxaa loo isticmaali karaa kala goysyada dhuunta saliidda iyo qalabka kalluumaysiga hoose. 2000m

Faa'iidooyinkayaga
1.HengYang ama TPCO bir gaar ah oo tayo sare leh iyo nadiifinteeda sare ee birta.
2.its dhumucdiisuna waxay derbiga lebbis iyo sax sare, tayada iftiinka, wax soo saarka iyo dhalidda waa mid aad u sarreeya, sidoo kale fududeeyo isku dhafka ah ee wax soo saarka dhululubo,
3.We soo saari kartaa dhexroor tuubo dhululubo la samayn karaa in 40 ~ 944.4mm, dhumucdiisuna waxay ugu yar derbiga 3.5 mm,
4.Sida qeexida caadiga ah ee dhululubada gaaska, wakhtiga bixinta waa dhakhso.
