Kodi mukufuna chitoliro chachitsulo? Yerekezerani China Supply ndi ASTM Specifications

Mphamvu ya kampaniyo imachokera ku mphamvu zake zazikulu zopangira zinthu zapamwamba. Tili ndi mizere 13 yopangira mapaipi achitsulo chozungulira ndi mizere 4 yopangira yoteteza dzimbiri ndi kutentha, yomwe imatha kupanga mapaipi achitsulo chozungulira okhala ndi mainchesi akunja kuyambira mamilimita 219 mpaka mamilimita 3500 ndi makulidwe a makoma mpaka mamilimita 25.4.

Zogulitsa zake za mtundu wa "Wuzhou" sizimangotsatira miyezo yambiri yapadziko lonse lapansi monga API Spec 5L ndi EN 10219, komanso zimakwaniritsa zofunikira za miyezo yofunika kwambiri monga ASTM A139 ndi ASTM A252.

Mapaipi achitsulo awa aku China omwe akutsatira miyezo ya ASTM ali ndi njira zambiri zogwiritsira ntchito. Agwiritsidwa ntchito bwino m'mapulojekiti ofunikira monga maukonde operekera madzi ndi madzi otayira m'matauni, mayendedwe a gasi ndi mafuta achilengedwe akutali, komanso makina opachikira mapaipi, zomwe zimapangitsa kuti "mitsempha yamagazi" ikhale yolimba komanso yolimba pomanga zomangamanga padziko lonse lapansi.

Kusankha wopanga yemwe ali ndi ziphaso zoyenerera padziko lonse lapansi ndi gawo loyamba lotsimikizira kudalirika kwa mapulojekiti a mapaipi kwa nthawi yayitali. Cangzhou Spiral Steel Pipe Group, chifukwa chotsatira kwambiri miyezo ya ASTM komanso mphamvu yopangira yokhazikika, imapatsa makasitomala mayankho amodzi kuyambira pakupanga mpaka polimbana ndi dzimbiri.

Kuti mudziwe zambiri zokhudza zofunikira, tsatanetsatane wa satifiketi ndi kuthekera kosintha mapaipi athu achitsulo ozungulira omwe amatsatira muyezo wa ASTM, chonde lemberani gulu lathu la akatswiri kuti mupeze upangiri waukadaulo mwatsatanetsatane komanso mawu ofotokozera.
