Pamili kareng materyales para keng valve sealing surfaces

Ing sealing surface da reng steel valves (DC341X-16 Double flanged eccentric butterfly valve) keraklan gagawan de (TWS valve)surfacing welding. Deng materyales a gagamitan para keng valve surfacing makadake la keng apat a maragul a kategorya agpang keng uri ning alloy, ilapin deng cobalt-based alloys, nickel-based alloys, iron-based alloys, ampo copper-based alloys. Deting alloy materials gagawan dong electrodes, welding wires (kayabe na ing flux-cored wires), fluxes (kayabe na ing transition alloy fluxes) ampo alloy powders, atbp., ampo gagawan dong surface kapamilatan ning manual arc welding, oxyacetylene flame welding, tungsten argon arc welding, submerged arc welding ampo automatic arc welding.

Ing pamili da reng valve sealing surface surfacing materials (DC341X3-10Double flanged eccentric butterfly valvebody sealing ring) keraklan makabasi ya keng temperatura ning pamangamit, pressure ning obra ampo ing corrosiveness ning balbula, o ing uri ning balbula, ing istruktura ning sealing surface, ing sealing specific pressure ampo ing allowable specific pressure, o ing production ampo manufacturing conditions ning enterprise, ing processing capacity ning equipment ampo ing technical ability ning surfacing ampo ing requirements da reng users. Ing optimized a disenyu dapat ya namang gamitan, at ing sealing surface material a maki mababang presyu, simpleng prosesu ning pamaglalang ampo matas a kahusayan ning pamaglalang dapat yang mapili lalam ning kundisyun a makatupad king performance ning (D341X3-16 Double flanged concentric butterfly valve )valve.

Deng mapilan kareng materyales a gagamitan para keng pamag-surface kareng valve sealing surfaces atin lang metung a porma, o electrode o welding wire o alloy powder, inya metung mung paralan ning pamag-surface ing malyaring gamitan. Deng aliwa gagawan dong welding rods, welding wires o alloy powders keng miyayaliwang porma, antimo ing stellite l 6 alloy, pareung welding rods (D802), welding wires (HS111) ampo alloy powders (PT2102), kaybat manual arc welding, oxy2acetylene flame welding, tungsten argon welding, wire arc welding plasma plasma arc welding ing welding ampo reng aliwang paralan malyari lang gamitan para keng surfacing welding. Potang mamili kang materyales para keng valve sealing surface, dapat tamung ikonsidera ing pamamili keng surfacing method a maki mature technology, simpleng prosesu ampo matas a production efficiency ning enterprise, para makasiguradung ing kayang performance keng surfacing manufacturing ning sealing surface.

Ing sealing surface ya ing susi ning valve (D371X-10 Wafer butterfly valve), at ing kalidad na direktang makaapektu keng bie ning serbisyu ning balbula. Ing makatuliran a pamili keng materyales ning valve sealing surface metung ya kareng importanting paralan para asundu ing bie ning valve. Dapat iwasan ing e pamikaintindi keng pamili kareng materyales a pang-seal ning balbula.

Mito 1: Ing katigasan ning balbula (D371X3-16C) matas ya ing sealing surface material, at masanting ya ing wear resistance na.

Deng eksperimentu papakit da na ing wear resistance ning valve sealing surface material makabasi ya keng microstructure ning metal material. Deng mapilan a metal a materyales a maki austenite bilang matrix ampo ditak a hard phase structure ali la masyadung matibe, pero ing karelang wear resistance masanting ya. Ing sealing surface ning valve atin yang matas a hardness para e ya masugat ampo magasgas kareng matigas a debris keng medium. Nung isipan mu ngan, ing hardness value HRC35~45 ing ustung-ustu.

Myth 2: Ing presyu ning valve sealing surface material matas ya, at masanting ing kayang performance.

Ing presyu ning metung a materyal yapin ing kayang sariling katangian a kalakal, kabang ing pamagganap ning materyal yapin ing kayang pisikal a katangian, at alang kailangang relasyun kareng adwang deti. Ing cobalt metal keng cobalt-based alloys manibatan ya keng imports, at matas ya presyu, inya matas ya ing presyu da reng cobalt-based alloy materials. Deng cobalt-based alloys atin lang masanting a wear resistance keng matas a temperatura, kabang nung gamitan la keng normal ampo medium a temperatura, ing presyu/performance na medyu matas ya. keng pamili kareng valve sealing surface materials, dapat mapili la reng materyales a mababa presyu/performance.

Myth 3: nung ing sealing surface material ning valve atin yang masanting a corrosion resistance keng masikan a corrosive medium, kailangan yang makibagay kareng aliwang corrosive media.

Ing corrosion resistance da reng metal a materyales atin yang sariling komplikadung mekanismo, ing materyal atin yang masanting a corrosion resistance keng masikan a corrosive medium, ampo ing kundisyun magbayu yang bagya, antimo ing temperatura o medium concentration, ing corrosion resistance mibayu ya. Para keng aliwang corrosive medium, mas maragul ing pamiyaliwa ning corrosion resistance. Ing corrosion resistance da reng metal a materyales malyari mung abalu kapamilatan ning pamag-eksperimentu, at ding kaugnayan a kundisyun dapat lang aintindian para king pamangilala kareng kaugnayan a materyales, at e dapat bulag-bulag a pautangan.
