Isitayela sase-Europe se-China 3PP 3PE Coating Carbon Steel Pipe
I-China 3PP 3PE Coating ye-Carbon Steel Pipe engenamthungo
Ukuze ezahlukene ubukhulu 3 PE enamathela ukujiya ihlukile. Imininingwane enamathiselwe ukuze kusetshenziswe ireferensi

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
