ASME B16.9 Dimansyon redukteur

Reduktèse youn nan ekipman kle nan estanda ASME B16.9 la. Yo itilize yo konekte de tiyo ak dyamèt nominal diferan, ki pèmèt likid la tranzisyon an dyamèt nan tiyo a pandan y ap kenbe estabilite nan koule likid la ak diminye pèt presyon oswa tourbiyon ki te koze pa chanjman toudenkou nan vitès koule. Yo lajman itilize nan sistèm tiyo endistriyèl tankou pétrochimique, gaz natirèl, pouvwa, ak tretman dlo.

Klasifikasyon Kalite redukteur

Rediksyon konsantrik:Aks tiyo yo nan tou de bout yo kowenside, epi seksyon transvèsal la simetrik ak sikilè. Yo apwopriye pou senaryo kote gwo konsistans nan aks tiyo yo mande epi pa gen okenn nesesite pou separasyon gaz-likid (tankou tiyo transpò likid).

Rediksyon ekssantrik:Aks yo nan tiyo yo nan tou de bout yo paralèl men yo pa kowenside, ak yon eksantrisite. Yo apwopriye pou transpòte gaz-likid likid melanje (tankou tiyo vapè) oswa senaryo kote akimilasyon likid nan pati anba tiyo a bezwen evite. Yo ka adapte yo a diferan kondisyon travay atravè metòd enstalasyon "anwo-plat" oswa "anba-plat".

ASME B16.9 Tolerans dimansyon pou redukteur

Tolerans Dyamèt Eksteryè

Devyasyon akseptab pou dyamèt ekstèn tou de gwo ak ti bout yo se ± 1%, ak yon devyasyon maksimòm ki pa depase ± 1.6mm.

Mi Tolerans epesè

Epesè miray minimòm lan pa dwe mwens pase 90% valè estanda espesifye a, epi pa gen okenn limit siperyè pou epesè maksimòm miray la (men dyamèt enteryè a dwe satisfè kondisyon koule likid yo).

Tolerans longè

Devyasyon akseptab pou longè estanda se ± 6.4mm (pou dyamèt nominal mwens pase oswa egal a DN200) ak ± 12.7mm (pou dyamèt nominal > DN200). Longè espesyal yo dwe gen tolerans ki endike sou desen yo, ak devyasyon an pa dwe depase ± 3%.

Tolerans eksantrisite

Devyasyon akseptab nan eksantrisite se ± 0.8mm (pou dyamèt nominal mwens pase oswa egal a DN100) ak ± 1.6mm (pou dyamèt nominal > DN100). Depase limit sa a pral lakòz aks tiyo a chanje apre enstalasyon, ki afekte pèfòmans sele.
