Iyo curvature radius yesimbi isina tsvinaichadzorwa. Semuenzaniso, kana kureba kweradius iri 1.5D, radius ye curvature inofanira kunge iri mukati mekushivirira kunodiwa.

Sezvo mazhinji eiyi pombi fittings anoshandiswa welding, kuitira kuti uvandudze welding mhando, migumo inoshandurwa kuita grooves, ine imwe kona uye imwe mupendero. Chinodiwa ichi zvakare chakasimba. Pane zvigadziro pahukobvu hwemupendero, kona uye kutsauka siyana, uye kune akawanda akawanda geometric dimensions kupfuura pombi fittings. Hunhu hwepamusoro uye hunyanzvi hwemagokora hwakanyanya kufanana nehwepombi. Kuti zvive nyore kusungira, zvinhu zvesimbi zvichave zvakafanana neyepombi yakabatana.

1. Sezvo akawanda epipe fittings anoshandiswa pakushongedza, kuitira kuti uvandudze welding quality, migumo inoshandurwa kuva grooves, ine imwe kona uye imwe mucheto. Chinodiwa ichi zvakare chakasimba. Pane mitemo pamusoro pekukora kwemupendero, kona uye kutsauka. Hunhu hwepamusoro uye humiro hwemagetsi hwakafanana nehwemapombi. Kuti zvive nyore zvekushongedza, giredhi resimbi yepipe fittings uye mapaipi akabatanidzwa zvakafanana.

1. Kureva kuti, zvese zvepombi zvinoiswa zvichave pasi pekugadziriswa kwepamusoro, uye iron oxide sikero pane yemukati neyekunze nzvimbo ichapfapfaidzwa nekupfurwa nekupenengura, uye yozoputirwa nependi yekudzivirira. Izvi ndezvekuda kunze kwenyika. Uyezve, muChina, zvakare kufambisa kufambisa uye kudzivirira ngura uye oxidation.

1. Ndiko kuti, zvinodiwa pakurongedza. Kune zviduku zviduku zvepombi, zvakadai sekutengesa kunze, mabhokisi emapuranga anoda kuitwa, anenge 1 cubic mita. Zvinotaridzirwa kuti nhamba yemagokora mumabhokisi akadaro haigoni kudarika tani imwe. Iyo chiyero inobvumira masutu, ndiko kuti, makuru seti uye madiki seti, asi huremu hwese haugone kudarika 1 toni. Pazvimedu zvakakura y, pasuru imwe chete inodiwa.
