Ifekthri ethengisa i-China High Quality Carbon Steel Pipe
Kuleli sonto sithumele iziqukathi ezingama-20 zepayipi lensimbi elingenamthungo GB3087 20# kuphrojekthi yasekhaya yaseSupermarket.
ungathola ipayipi ehlukene kusuka ezigayweni ezahlukene. Ungavele ubone inani ngoba mhlawumbe uzoba ne-troube eyengeziwe
ngemva kokuthola impahla.
Uhlolojikelele
Isicelo
Isetshenziswa kakhulu ukwenza insimbi yesakhiwo sekhabhoni ephezulu, ipayipi le-boiler elicindezelayo eliphansi, ipayipi lensimbi elishisayo elishisayo.
Ibanga Eliyinhloko
Ibanga lensimbi ephezulu ye-carbon structural: 10#,20#

Isidingo Sokuhlola
Ngokungeziwe ekuqinisekiseni ukwakheka kwamakhemikhali kanye nezakhiwo zemishini, ukuhlolwa kwe-hydrostatic kwenziwa ngakunye, futhi kwenziwa ukuhlolwa kwe-flaring ne-flattening. .Ngaphezu kwalokho , ET. UT ayatholakala
Ikhono Lokuhlinzeka
Ikhono Lokuhlinzeka: Amathani angu-2000 Ngenyanga Ngebanga ngalinye le-GB/T3087-2008 Ipayipi Lensimbi Lekhabhoni Elingenamthungo
Ukupakisha
Kuyizinqwaba Nasebhokisini Lokhuni Eliqinile
Ukulethwa
Izinsuku ezingu-7-14 uma zisesitokweni, izinsuku ezingu-30-45 zokukhiqiza
Inkokhelo
