Carbon Steel National Standard Flange Gate Valve

Ndife akatswiri opanga ma valve omwe ali ndi ziphaso za ISO, API ndi CE. Tili ndi zida zopangira zapamwamba komanso gulu lonse la machitidwe owongolera. Timavomerezanso maoda a OEM ndi ODM, okhala ndi madongosolo ochepa osinthika. Zogulitsa zathu zodalirika zimatumizidwa padziko lonse lapansi ndipo zimatchuka kwambiri ndi makasitomala.

Kodi ma flanges achitsulo a carbon pa mavavu a pachipata ndi ati?

Ma flanges achitsulo cha kaboni amakhala pansi pamiyezo yosiyanasiyana kutengera komwe mukuwagwiritsa ntchito. Zodziwika bwino ndi ASME B16.5 (American standard), EN 1092-1 (European standard), ndi GB/T 9113 series (Chinese national standard). Kwa mavavu athu amtundu wa carbon steel standard flange pachipata, nthawi zambiri timatsatira mfundo za GB kuti zigwirizane ndi mapaipi apanyumba. Miyezo iyi imatanthawuza kukula kwa flange, kuchuluka kwa kuthamanga, ndi mawonekedwe a bolt bolt, kuti valavu igwirizane bwino ndi mapaipi anu ndikukwaniritsa kalasi yokakamiza.

Makhalidwe Ofunika

Ndi miyezo iti yomwe imagwira ntchito pamavavu a zipata?

Mavavu a pachipata samapangidwa mofanana-amatsatira miyezo yosiyana malingana ndi komwe mukukonzekera kuzigwiritsa ntchito. Pantchito zolimba ngati zoyenga zamafuta ndi gasi, API 600 ndiye muyeso waukulu wamavavu azipata zachitsulo cholemera. ISO 6002 ndi mulingo wina wapadziko lonse lapansi womwe umagwirizana ndi API 600 pamitundu yamabonati opindika. Ndipo pama projekiti athu apakhomo komanso ambiri ogulitsa, timagwiritsa ntchito muyezo waku China wa GB/T 12234. Iliyonse mwamiyezo iyi imalongosola ndendende momwe valavu iyenera kupangidwira, zida zomwe mungagwiritse ntchito, momwe zimayesedwera kukakamizidwa, ndi miyeso yomwe mungapeze. Mwanjira imeneyo, mumadziwa kuti valavu idzakwanira mzere wanu ndikugwira bwino pakapita nthawi.

Kodi flange imagwira ntchito yanji pa valve ya pachipata?

Flange kwenikweni ndi "nkhope yolumikizira" kumapeto kwa valve yachipata. Ndizomwe zimakulolani kuti mutseke valve paipi yanu kapena zipangizo zina. Mukamangitsa mabawuti, flange imakanikiza mofanana pa gasket kuti ipange chosindikizira cholimba, chopanda kutayikira. Izi zikutanthauza kuti palibe kutayikira kosokoneza, ndipo pambuyo pake ngati mukufuna kutulutsa valavu kuti muyikonzere kapena kuyisintha, ndikosavuta kumasula ndikuchotsa. Flange imafalitsanso kupanikizika kogwira ntchito molingana ndi mgwirizano, kotero kuti kugwirizana kumakhalabe kokhazikika ngakhale pamene dongosolo likulemedwa.

Kodi mungafotokoze muyeso wa API 600?

API 600 kwenikweni ndi muyeso wovuta, wopanda pake wochokera ku American Petroleum Institute. Amapangidwira makamaka mavavu azitsulo zachitsulo za bonnet-mtundu womwe mumapeza m'malo oyeretsera, mapaipi amafuta & gasi, ndi malo ena ogulitsa omwe amafunikira kwambiri.

Simadula mbali pazofunikira: zosankha zakuthupi ziyenera kukhala zolondola, kapangidwe kake kamayenera kukhazikika, kupanga kuyenera kutsatira malamulo okhwima, ndipo valavu iliyonse iyenera kupitilira mayeso ndi kutayikira isanachoke kufakitale. Mfundo yonse ndi yophweka: onetsetsani kuti valavu ikhoza kutenga kuthamanga kwakukulu, kutentha kwakukulu, ndi zofalitsa zankhanza, ndikugwirabe ntchito pamene mukuzifuna kwambiri. Ngati valavu yachipata imakumana ndi API 600, mukudziwa kuti idapangidwira ntchito zovuta, zolimbikira.
