I-ASTM A153: Izinga lezingxenye zensimbi ezifakwe emanzini ashisayo

I-Hot dip galvanizing ubuchwepheshe bokuvikela obusetshenziswa kakhulu emikhiqizweni yensimbi, eyenza i-zinc coating endaweni yensimbi ukuvimbela ukugqwala.Phakathi nale nqubo, izinga le-ASTM A153 libe umhlahlandlela obalulekile emkhakheni wokufaka ugesi oshisayo.

Le ndatshana izohlinzeka ngesingeniso esinemininingwane yencazelo, ububanzi bokusebenza, nokubaluleka kwezinga le-ASTM A153.

Iyini i-ASTM A153?

I-ASTM A153 iyindinganiso eyathuthukiswa yi-American Society for Testing and Materials (ASTM International), egxile ekumiseni izinga lezingxenyekazi zensimbi ezishisayo zediphu.Idizayini yaleli zinga ihlose ukuqinisekisa ukuthi izingxenye zikathayela zediphu ezishisayo zithobela uchungechunge lwezicaciso nezindlela zokuhlola ukuze kuqinisekiswe ukumelana nokugqwala kwazo kanye nekhwalithi.

Ububanzi obusebenzayo:

Izinga le-ASTM A153 lisebenza kakhulu ezingxenyeni ezincane zensimbi, njengamabhawudo, amantongomane, izikhonkwane, izikulufu, njll. Ibuye ibonakale ngokujwayelekile phakathi kwemikhiqizo yokuxhuma, njenge.izindololwane, tee, futhiizinciphisi;Icacisa izidingo eziyisisekelo kanye nokucaciswa lezi zingxenye okufanele zibe nakho ngesikhathi senqubo yokufaka amadiphu ashisayo.Inhloso ye-galvanizing ukuhlinzeka ngendwangu evikelayo ukuvimbela ukulimala kwensimbi ngenxa yokugqwala ngesikhathi sokusetshenziswa.

Izimfuneko ezijwayelekile:

1.Ugqinsi lwezinki:

I-ASTM A153 icacisa ubukhulu obuncane be-zinc coating.Imvamisa i-lightweight galvanized, ihlinzeka ukumelana nokugqwala okuyisisekelo.

2.Inkambu yohlelo lokusebenza:

Isetshenziswa kakhulu ezindaweni zasendlini ezinezidingo eziphansi kakhulu zokumelana nokugqwala, njengefenisha, uthango, i-hardware yasendlini, njll.

3.Izidingo zezinga lokushisa:

Izinga lokushisa lediphu lento ethile liyacaciswa ukuze kuqinisekiswe ukuthobelana nezindinganiso.

Kungani ibalulekile?

Ukubaluleka kwezinga le-ASTM A153 ukuthi liqinisekisa ukuthi izingxenye zensimbi ezikhiqizwayo ziphathwa kahle futhi zinokumelana nokugqwala okuhle.Lokhu kusiza ukunweba impilo yesevisi yezingxenye zensimbi nokuqinisekisa ukuqina kwazo ezindaweni ezithile zohlelo lokusebenza.

Izinga le-ASTM A153 lidlala indima ebalulekile embonini yokufaka amadiphu ashisayo.Ihlinzeka ngesethi yezinkombandlela zokuqinisekisa ukuthi abakhiqizi nonjiniyela bangakhiqiza izingxenye zensimbi ezinekhwalithi ehlangabezana nezindinganiso.Ngokulandela leli zinga, izingxenye ezikhiqiziwe zinokumelana nokugqwala okuhle kakhulu futhi zinikeza izingxenye zensimbi ezithembekile zokusetshenziswa okuhlukahlukene.
