Galvanizing waa hab lagu dabaqo lakabka ilaalinta ee zinc birta ama birta si looga hortago daxalka. Habka waxaa caadi ahaan loo isticmaalaa soo saarista tuubooyinka, gaar ahaan kuwa loo isticmaalo warshadaha kala duwan sida dhismaha, saliidda iyo gaasta, iyo biyaha.Heerarka galvanizing ee tuubooyinkawaxay muhiim u yihiin hubinta tayada iyo cimri dhererka tuubooyinka galvanized. Aan u daadagno faahfaahinta heerarka galvanizing tuubooyinka iyo waxa ay ula jeedaan khadka galvanizing tube.
Dhuumaha galvaningHeerarka waxaa inta badan dejiya Ururka Caalamiga ah ee Bulshada Maraykanka ee Imtixaanka iyo Qalabka (ASTM). ASTM waxay dejisaa heerar gaar ah habka galvanized, oo ay ku jiraan dhumucda lakabka galvanized, ku dhejinta dahaarka, iyo tayada guud eegalvanizeddusha sare. Heerarkan ayaa muhiim u ah ilaalinta sharafta tuubada galvanized iyo hubinta waxqabadkeeda ee codsiyada kala duwan.
Mid ka mid ah halbeegyada muhiimka ah ee tuubada galvanized waa ASTM A123/A123M, kaas oo qeexaya shuruudaha daahaarka galvanized ee alaabta birta ah, oo ay ku jiraan tuubooyinka. Heerkani wuxuu qeexayaa dhumucda ugu yar ee daahan, dhejinta iyo dhamaystirka tuubooyinka galvanized. Waxa kale oo ay bixisaa habraacyada kormeerka iyo tijaabintadahaarka galvanizedsi loo hubiyo u hoggaansanaanta heerarka.
In dhuumaha galvanizingU hoggaansanaanta heerarka ASTM A123/A123M ayaa muhiim u ah soo saarista tuubo galvanized tayo sare leh. Habka galvanizing sida caadiga ah waxay ku lug leedahay dhowr marxaladood, oo ay ku jiraan daawaynta dusha sare, galvanizing-kulul iyo habayn ka dib. Marxalad kasta waa in ay u hoggaansamaan heerarka ASTM si loo gaaro dhumucda dahaarka loo baahan yahay iyo tayada.
Diyaarinta dusha sare waxay ku lug leedahay nadiifinta tuubooyinka si looga saaro miridhku, miisaan ama wasakh kale oo laga yaabo inay ka hortagtogalvaninglakabka ka dheggan. Talaabadani waa mid muhiim ah si loo xaqiijiyo ku-xidhnaanta saxda ah eedaahan galvanizeddusha tuubada. Habka galvanization-ku-kululku waxa uu ku lug leeyahay galinta tuubooyinka nadiifka ah ee qubeyska zinc la dhalaaliyay, kaas oo macdan ahaan ugu xidha birta si ay u sameeyaan dahaadh ilaalin ah..
Habka galvanizing ka dib, dhuunta ayaa mari doonta habayn ka dib, taas oo ay ku jiri karto deminta, bakhtiinta ama hubinta dhumucda dahaarka iyo dhejinta. Talaabooyinkan habayntu ka dib waa muhiim si loo xaqiijiyo in tuubada galvanized-ku buuxisay shuruudaha jaangooyada ASTM oo ay diyaar u tahay in loo isticmaalo codsiyo kala duwan.
U hoggaansanaantadhuumaha galvanizingHeerarka ma aha oo kaliya inay hubiyaan tayada iyo cimri dhererka tuubada, laakiin sidoo kale waxay gacan ka geysataa waxqabadkeeda muddada dheer iyo caabbinta daxalka. Dhuumaha galvanized-ka ee ASTM-ku waxay ku habboon yihiin bannaanka, qoyaan badan iyo bay'adaha daxalka, taasoo ka dhigaysa mid ku habboon codsiyada sida qaybinta biyaha, taageerada qaabdhismeedka iyo nidaamyada tuubooyinka warshadaha.
Marka la soo koobo, heerarka galvanizing tuubooyinka ee ay qeexday ASTM International ayaa door muhiim ah ka ciyaara khadka wax soo saarka ee dhuumaha galvanizing. U hoggaansanaanta heerkan ayaa xaqiijinaysa taastuubo galvanizedbuuxiyo shuruudaha lagama maarmaanka u ah dhumucda dahaarka, adhesion iyo tayada guud. Adigoo raacaya heerarka ASTM,soo saarayaashasoo saari karatuubo galvanized ah oo tayo sare lehkaas oo bixiya ilaalinta daxalka sare iyo nolosha adeegga ee codsiyada warshadaha iyo ganacsiga ee kala duwan.
