Umbhobho wentsimbi ojikelezileyo ojikelezileyo we-ASTM A36
Umbhobho weNtsimbi oDidiweyo oshushu ojikelezileyo
A36
Ekubeni i-galvanizing yi-chemical reaction eya kwenza i-zinc layer phezu kombhobho wensimbi, ukuxhatshazwa kwe-corrosion of galvanized steel pipes kungcono kuneminye imibhobho yensimbi, ngakumbi kwiindawo ezifana nokufuma kunye nemvula ye-asidi.i-anti-corrosion effect.Ngelo xesha, umphezulu wensimbi yombhobho we-galvanized nawo uneempawu zokuziphilisa.Xa ubuso bombhobho wensimbi bonakaliswe, i-zinc layer entsha iya kwenza ngokuzenzekelayo ukukhusela ngaphakathi kwipayipi yensimbi.
I-ASTM A36 umbhobho wensimbi ojikelezileyo owenziwe ngesinyithi ucutshungulwa ngeenkqubo ezifana ne-hot dip plating okanye i-electro-galvanizing, enokuthintela ngokufanelekileyo ukubola komphezulu wemibhobho yentsimbi kunye nokwandisa ubomi babo benkonzo.
Imibhobho yentsimbi ejikelezileyo editshiweyo etshisiweyo inokumelana nemozulu encomekayo kwaye ingasetyenziswa kwiimeko ezahlukeneyo zemozulu, ngoko ke isetyenziswa ngokubanzi kulwakhiwo lwangaphandle kunye nokuveliswa kwezixhobo.
Inkcazo ye-dimensional yemibhobho ye-galvanized ngokuqhelekileyo ichazwa yi-diameter yangaphandle (OD), ubukhulu bodonga (WT) kunye nobude (L).
1. I-diameter yangaphandle (OD): I-OD ngumgama ukusuka kumphezulu wangaphandle wombhobho ukuya kwiziko, ngokuqhelekileyo ngee-intshi (intshi) okanye iimilimitha (mm) kwiyunithi.I-OD eqhelekileyo ibandakanya i-1/2 intshi, i-3/4 intshi, i-intshi eyi-1, i-1-1/4 intshi, njl.
2. Ubukhulu bodonga (WT): ubukhulu bodonga bubunzima bodonga lombhobho, ngokuqhelekileyo ngee-intshi okanye iimilimitha.Ubunzima bodonga buchaphazela ngokuthe ngqo amandla kunye nokuqina kombhobho.Ubukhulu beendonga ezityebileyo buhlala busetyenziswa kwizicelo ezifuna umthamo omkhulu wokuthwala umthwalo.
3. ubude (L): ubude bubonisa ubude obupheleleyo bombhobho, ngokuqhelekileyo kwiinyawo (unyawo) okanye iimitha (imitha).Ubude obuqhelekileyo bubandakanya i-10 ft, 20 ft, 6 yeemitha, njalo njalo.Iinkcukacha zobude bombhobho zingenziwa ngokwezifiso ukuhlangabezana neemfuno zeprojekthi ethile.
I-ASTM A36 umbhobho wensimbi ojikelezayo ufanelekile kwiindawo ezininzi, ezifana nokwakhiwa, ukwakhiwa kweenqanawa, ukwakhiwa kwebhulorho, iindlela zokugada, ukuthutha ioli kunye negesi, njl.
Kwintsimi yolwakhiwo, iibhobho zetsimbi ezinobubanzi obukhulu zisetyenziselwa ukwenza imiqadi yesakhiwo sentsimbi kunye neentsika, izitebhisi, izixhaso zephahla kunye namanye amacandelo.
Kulwakhiwo lweenqanawa, umbhobho wentsimbi ojikelezileyo we-ASTMA36 ungasetyenziswa njengezixhaso zezakhiwo zeenqanawa kunye nezixhobo zoomatshini.
Kulwakhiwo lwebhulorho, umbhobho wentsimbi ogxunyekwe ngamazimba ungasetyenziselwa ukwenziwa kweepier zebhulorho, iintsimbi zokugada iibhulorho kunye namanye amacandelo.
Ekuthuthweni kwe-oyile kunye negesi yendalo, umbhobho wensimbi oshushu wokudipha usetyenziswa kakhulu ekwakhiweni kweenkqubo zemibhobho kwaye unokumelana nokugqwala okuhle kunye nokumelana noxinzelelo.
Ukukhuselwa kokusingqongileyo kunye nozinzo Ngexesha lenkqubo yokwenziwa kwe-ASTMA36 yombhobho wentsimbi, inkqubo yokugalela ithatha inkqubo yokuvelisa indalo kwaye ayiyi kubangela ukungcoliseka kwendalo.
Umbhobho wensimbi ngokwawo unokuphinda usetyenziswe kwaye usetyenziswe kwakhona, ohambelana nombono wophuhliso oluzinzileyo.
Imibhobho yensimbi ene-galvanized inobomi obude benkonzo, inokunciphisa ukugcinwa kunye nokutshintshwa kwamaxesha amaninzi, kunye nokunciphisa ukusetyenziswa kwezixhobo.
I-ASTMA36 ingumbhobho wentsimbi oguquguqukayo, unokumelana ne-corrosion kunye nemveliso yombhobho wentsimbi ezinzileyo.
