Mapaipi onse achitsulo a kaboni omwe amagwiritsidwa ntchito potentha (osakwana -20 ° C) akuyenera kutengera muyezo wa GB6479, womwe umangotchula zofunikira pakulimba kwa zinthu zotsika kutentha.

GB3087ndiGB5310Miyezo ndi miyeso yokhazikitsidwa mwapadera yamapaipi achitsulo chowotchera. "Malamulo Oyang'anira Chitetezo cha Boiler" akugogomezera kuti mapaipi onse olumikizidwa ndi ma boilers ali mkati momwe angayang'anire, ndipo kugwiritsa ntchito zida ndi miyezo yawo kuyenera kutsatira "Malamulo Oyang'anira Chitetezo cha Boiler". Chifukwa chake, ma boiler, zopangira magetsi, zida zotenthetsera ndi zopangira petrochemical zimagwiritsa ntchito Mapaipi amtundu wa anthu (operekedwa ndi dongosolo) akuyenera kutengera miyezo ya GB3087 kapena GB5310.

Ndikoyenera kudziwa kuti mtengo wamapaipi achitsulo okhala ndi mipope yabwino yachitsulo ndi yokwera kwambiri. Mwachitsanzo, mtengo wa GB9948 ndi pafupifupi 1/5 wapamwamba kuposa wa zinthu za GB8163. Choncho, posankha zitsulo chitoliro mfundo mfundo zakuthupi, ziyenera kuganiziridwa momveka bwino malinga ndi mmene ntchito. Iyenera kukhala yodalirika komanso yodalirika. Kukhala wachuma. Tiyeneranso kukumbukira kuti mapaipi achitsulo molingana ndi GB/T20801 ndi TSGD0001, GB3087 ndi GB8163 sangagwiritsidwe ntchito pa mapaipi a GC1 (pokhapokha ngati ultrasonically, khalidweli silili lotsika kuposa L2.5 mlingo, ndipo lingagwiritsidwe ntchito kwa GC1 ndi mapangidwe Kuthamanga kosaposa 4.0Mpa (1) pipeline).
