Pamiyaliwa ning Forged Steel Valve ampo Cast Steel Valve

I. Prosesu ning Pamaglalang

Forged Steel Check Valve Manufactures China:

Gawa ya kapamilatan ning prosesu ning forging, ing steel billet papainitan de at ing pressure (antimo ing pamamartilyu, pamag-extrusion) mipatupad ya ba yang gawan iti, at kaybat ing mechanical processing gagawan de.

Ing prosesu ning forging gagawan na lang mas mapino deng metal grains ampo ing istruktura makapal ya, alang depektu antimo reng pores ampo slag inclusions.

Cast Steel Valve:

Gagawa ya kapamilatan ning prosesu ning pamag-cast, ing bakal a tinunaw mibubu ya king metung a hulmahan ba yang lumamig at maporma, at kaybat iprosesu ya.

Ing prosesu ning pamag-cast malyari yang magdalang problema antimo reng pores, shrinkage cavities o e pantas a istruktura, a kailangang i-improve kapamilatan ning tutuking pamagprosesu.

II. Material Properties

Forged Steel Valve:

Matas a sikanan: Ing pamag-forge lalako nala reng depektu keng kilub, ampo ing sikanan ning mekanikal (tensile resistance ampo impact resistance) mas masanting ya kesa kareng casting.

Mas masanting a resistensya keng pressure: masanting ya para keng matas a pressure, matas a temperatura o matinding kundisyun ning obra.

Mas masanting a pamag-seal: Ing metal atin yang matas a densidad at e ya madaling tumagas.

Cast Steel Valve:

Mas mababa ing katatagan: Ing casting structure malyari yang maglaman microscopic defects, inya mas madali yang mika crack keng sobrang stress.

Mas mababa ing gastus: masanting ya para keng mass production da reng complex-shaped o mangaragul a balbula.

III. Istruktura & Timbang

Forged Steel Valve:

Ing istruktura medyu simple ya, keraklan symmetrical o compact ing disenyu. Mas magaan (mga 20% anggang 30% mas magaan kesa kareng cast steel valves a parehu ing specifications).

Cast Iron Wafer Butterfly Valve Suppliers China:

Deng komplikadung istruktura (antimo reng special-shaped flow channels, multi-cavity bodies) malyari lang gawan. Mas maragul ing timbang at keraklan mas makapal ing kapal ning pader bang makabawi king kakulangan king sikanan.

IV. Applicable Working Conditions

Forged Steel Valve:

Deng sistemang matas a presyur ampo matas a temperatura: antimo reng istasyun ning kuryenti, industriya ning petrochemical, ampo reng pipeline ning singaw a matas a presyur.

Mababa ing temperatura ning kapaligiran: antimo ing liquefied natural gas (LNG) systems, ing forged steel mas masanting ya keng mababang temperatura.

Delikadung media: makalasun, masilab ampo makasabog a likidu (uli ning mas matas a reliability).

China Cast Iron Swing Check Valve:

Medium ampo low pressure conventional a kondisyun ning obra: antimo ing water treatment, general industrial pipelines, ampo low-pressure steam.

Corrosive media: Ing pamaglaban keng corrosion malyari yang mas masanting kapamilatan ning pamagdagdag kareng alloy elements (antimo reng cast stainless steel valves).

Maragul a diametru a balbula: Nung limitadu ya ing prosesu ning pamag-forge, mas masanting ing pamag-cast para kareng mangaragul a katawan ning balbula.

V. Gastus & Panaun ning Pamagdala

Forged steel valves:Matas a gastus keng raw material, maragul a puhunan keng forging dies ampo gamit. Makabang siklo ning pamaglalang, masanting para kareng malating batch o matas a pamantayan a kailangan. Keraklan mas matas la reng presyu da reng unit.

Cast steel valves:Ing gastus keng mold medyu mababa ya, inya sa't masanting la para keng mass production. Makuyad ya ing siklo ning pamaglalang, at mas makipagkumpetensya ing gastus.

VI. karaniwan a pamantayan ampo marka

China Forged Check Valve:

Specifications: ASTM A105 (carbon steel), A182 (stainless steel), atbp. Ing marking keraklan kayabe ya ing katayang “Forged”.

Cast Iron Gate Valve:

Specifications: ASTM A216 (carbon steel), A351 (stainless steel), atbp. Ing marking keraklan kayabe ya ing katayang “Cast”.
