Ipayipi Lensimbi Eliyindilinga Eligandaywe I-ASTM A36
Ipayipi Lensimbi Eliyindilinga Elicwiliswe Ngensimbi
A36
Njengoba i-galvanizing iwukusabela kwamakhemikhali okuzokwenza ungqimba lwe-zinc ebusweni bepayipi lensimbi, ukumelana nokugqwala kwamapayipi ensimbi athathiwe kungcono kunokwamanye amapayipi ensimbi, ikakhulukazi ezindaweni ezinjengomswakama kanye nemvula ene-asidi.umphumela we-anti-corrosion.Ngesikhathi esifanayo, ubuso bensimbi yamapayipi e-galvanized bubuye bube nezinto zokuziphilisa.Lapho ingaphezulu lepayipi lensimbi lonakalisiwe, ungqimba olusha lwe-zinc luzokwakheka ngokuzenzakalelayo ukuvikela ingaphakathi lepayipi lensimbi.
Ipayipi lensimbi eliyindilinga eliyindilinga le-ASTM A36 licutshungulwa yizinqubo ezifana ne-hot dip plating noma i-electro-galvanizing, engavimbela ngempumelelo ukugqwala kwamapayipi ensimbi futhi andise impilo yawo yokusebenza.
Amapayipi ensimbi ayindilinga afakwe uthayela ashisayo anokumelana nesimo sezulu esihle futhi angasetshenziswa ezimweni zezulu ezihlukene, ngakho asetshenziswa kakhulu ekwakheni kwangaphandle nasekukhiqizeni imishini.
Ukucaciswa kobukhulu bamapayipi athathiwe kuvame ukuchazwa ngobubanzi obungaphandle (OD), ukushuba kodonga (WT) nobude (L).
1. Ububanzi bangaphandle (OD): I-OD ibanga ukusuka endaweni engaphandle yepayipi ukuya enkabeni, ngokuvamile ngamayintshi (intshi) noma amamilimitha (mm) eyunithi.I-OD evamile ihlanganisa i-intshi engu-1/2, i-intshi engu-3/4, intshi engu-1, i-intshi engu-1-1/4, njll.
2. ukujiya kodonga (WT): ukujiya kodonga ukujiya kodonga lwamapayipi, ngokuvamile ngamasentimitha noma amamilimitha.Ukuqina kwezindonga kuthinta ngqo amandla nokuqina kwepayipi.Ukuqina kwezindonga eziqinile kuvame ukusetshenziswa ezinhlelweni ezidinga umthamo omkhulu wokuthwala.
3. Ubude (L): ubude bubonisa ubude bepayipi lonke, ngokuvamile ezinyaweni (unyawo) noma amamitha (imitha).Ubude obujwayelekile buhlanganisa u-10 ft, 20 ft, 6 metres, njalonjalo.Ukucaciswa kobude bepayipi kungenziwa ngendlela oyifisayo ukuze kuhlangatshezwane nezidingo zephrojekthi ethile.
Ipayipi lensimbi eliyindilinga le-ASTM A36 lilungele izinkambu eziningi, njengokwakhiwa, ukwakhiwa kwemikhumbi, ukwakhiwa kwebhuloho, izinsimbi zokuqapha umgwaqo omkhulu, ezokuthutha zikawoyela negesi, njll.
Emkhakheni wokwakha, amapayipi ensimbi anobubanzi obukhulu avame ukusetshenziswa ekukhiqizeni imishayo yesakhiwo sensimbi namakholomu, izitebhisi zezandla, izisekelo zophahla nezinye izingxenye.
Ekwakhiweni kwemikhumbi, ipayipi lensimbi eliyindilinga le-ASTMA36 lingasetshenziswa njengezisekelo zesakhiwo semikhumbi yemikhumbi kanye nemishini yemishini.
Ekwakhiweni kwebhuloho, ipayipi lensimbi elingenalutho elingenalutho lingasetshenziswa ekwenzeni izinsimbi zamabhuloho, izinsimbi zokuqapha ibhuloho nezinye izakhi.
Ezokuthutha zikawoyela negesi yemvelo, ipayipi lensimbi elishisayo lisetshenziswa kabanzi ekwakhiweni kwezinhlelo zamapayipi futhi linokumelana nokugqwala okuhle nokumelana nokucindezela.
Ukuvikelwa kwemvelo kanye nokusimama Ngesikhathi senqubo yokukhiqiza ipayipi lensimbi elakha i-ASTMA36, inqubo yokufaka uthango isebenzisa inqubo yokukhiqiza ehambisana nemvelo futhi ngeke ibangele ukungcoliswa kwemvelo.
Ipayipi lensimbi ngokwayo lingaphinda lisetshenziswe futhi lisetshenziswe kabusha, elihambisana nomqondo wokuthuthukiswa okusimeme.
Amapayipi ensimbi anamapayipi anesikhathi eside sokusebenza, anganciphisa imvamisa yokugcinwa nokushintshwa, futhi anciphise ukusetshenziswa kwezinsiza.
I-ASTMA36 galvanized steel pipe iwumkhiqizo wamapayipi ensimbi oguquguqukayo, ukumelana nokugqwala futhi esimeme.
