Say pampili na materyales ed panag-seal na balbula

Say panagsara ed tapew na saray balbula ya asero (DC341X-16 Doble flanged eccentric butterfly valve) et kaslakan ya gagawaen na (TWS valve)surfacing welding. Saray materyales ya uusaren ed valve surfacing et naapag ed 4 ya manunan kategorya unong ed klase na alloy, salanti, cobalt-based alloys, nickel-based alloys, iron-based alloys, tan copper-based alloys. Sarayan materyales ya alloy et gagawaen ya electrode, welding wires (kaiba lay flux-cored wires), fluxes (kaiba lay transition alloy fluxes) tan alloy powders, tan arum nira, tan na-surface iratan panamegley na manual arc welding, oxyacetylene flame welding, tungsten argon arc welding, submerged arc welding tan plasmatic arc welding.

Say pampili na saray materyales ya pangiseal ed tapew na balbula (DC341X3-10Doble flanged eccentric butterfly valvebody sealing ring) et kaslakan ya nibase ed temperatura na pangusar, presyon na pantratrabaho tan inka-corrosive na balbula, odino say klase na balbula, say istruktura na tapew na sealing, say espisipikon presyon na sealing tan say naabuloyan ya espisipikon presyon, odino say kondisyon na produksyon tan panaggawa na negosyo, say kapasidad na panagproseso na kagawaan tan say teknikal a kapasidad na panag-tap tan saray kakaukolanen na saray manguusar. Nepeg met ya usaren so sankaabigan ya desinyo, tan say materyales ed tapew na sealing ya abeban presyo, simpli so proseso na produksyon tan atagey ya epektibo na produksyon et nepeg ya pilien diad kondisyon ya makapenek ed performance na (D341X3-16 Doble flanged concentric butterfly valve )balbula.

Arum ed saray materyales ya uusaren ed panag-surface na saray tapew na balbula et walaan labat na saksakey a porma, odino electrode odino welding wire odino alloy powder, kanian saksakey labat so nayarin usaren a paraan na panag-surface. Arum et gagawaen ya welding rods, welding wires odino alloy powders ed nanduruman nengneng, singa say stellite l 6 alloy, parehon welding rods (D802), welding wires (HS111) tan alloy powders (PT2102), insan manual arc welding, oxy2acetylene flame welding, tungsten argon welding, plasma arc welding plasma arc welding say panag-welding tan arum niran paraan et nayarin usaren parad panag-welding ed tapew. No manpipili na saray materyales ed panag-surface parad valve sealing surface, nepeg tayon ikonsidera so pampili na surfacing method ya walaan na matatken lan teknolohiya, simplin proseso tan atagey ya inkaepektibo na produksyon na negosyo, pian naseguro so pakasumpal na performance to ed surfacing manufacturing na sealing surface.

Say tapew na seal et manunan kabiangan na balbula (D371X-10 Wafer butterfly valve), tan say kalidad to et direktan mangaapekta ed bilay na balbula. Say makatunongan a pampili na materyales na valve sealing surface et sakey ed saray importantin paraan pian napaaligwas so serbisyo na balbula. Nepeg ya paliisan so agpantatalosan ed panagpili na saray materyales ed tapew na balbula.

Mito 1: Say inka-malet na balbula (D371X3-16C) so atagey a materyales ed tapew na sealing, tan maong so resistensya to ed panag-usar.

Ipapanengneng na saray eksperimento ya say resistensya na panag-usar na balbula ed tapew na tapew et nadetermina ed mikroistruktura na metal a materyal. Arum a metal a materyales ya walay austenite bilang matrix tan daiset a hard phase structure et aliwan tanton malet, balet ta maong so resistensya ra ed pakasulong. Say sealing surface na valve et walay pigaran atagey ya inka-malet pian ag-onsugat tan ag-gasgasan na saray malet ya debris ed pegley. No ikonsidera so amin a bengatla, say balor na inka-malet ya HRC35~45 et matukoy.

Mito 2: Atagey so presyo na materyales ed tapew na balbula, tan maong so performance to.

Say presyo na sakey a materyal et say dilin katangian to, bangta say performance na materyal et say pisikal a katangian to, tan anggapoy nakaukolan a siglaotan na saratan a dua. Say cobalt metal ed cobalt-based alloys et manlalapud saray import, tan atagey so presyo to, kanian atagey so presyo na cobalt-based alloy materials. Saray cobalt-based alloys et walaan na maong ya resistensya ed atagey ya temperatura, bangbalet no usaren ed normal tan medium a temperatura, say presyo/performance to et medyo atagey. Diad pampili na saray materyales ed tapew na balbula, saray materyales ya abeba so presyo/performance da so nepeg ya pilien.

Mito 3: No say materyales na sealing surface na balbula et walaan na maong ya resistensya ed corrosion diad mabiskeg ya corrosive medium, kaukolan ya mibagay itan ed arum ya corrosive media.

Say resistensya ed corrosion na saray materyales a metal et walaan na dilin komplikadon mekanismo, say materyal et walaan na maong ya resistensya ed corrosion diad mabiskeg a corrosive medium, tan saray kondisyon so manguuman na daiset, a singa say temperatura odino konsentrasyon na medium, say resistensya ed corrosion et manguuman. Parad sananey a makapasinagem a medium, say resistensya ed panag-apag-apag so mas baleg so pandurumaan to. Say resistensya ed corrosion na saray metal a materyales et naamtaan labat panamegley na saray eksperimento, tan saray matukoy a kondisyon so nepeg a natalosan parad reperensya manlapud saray matukoy a materyales, tan ag nepeg ya alaen a bulag.
