Mapaipi opangidwa ndi longitudinal
Zoyambitsa Zamalonda
Mapaipi achitsulo opangidwa ndi longitudinal omwe nthawi zambiri amawaika kutengera zinthu zomwe amapangidwa, momwe amagwiritsidwira ntchito, komanso miyezo yomwe amatsatira. Nthawi zambiri, mipope yachitsulo yotalikirapo yomwe imatanthawuza miyezo wamba ndi magulu a Submerged-Arc Welded Steel Pipes.
Zofunika:
Longitudinal welded zitsulo mipope akhoza m'gulu potengera zinthu zomwe iwo anapanga, monga mpweya zitsulo, zitsulo zosapanga dzimbiri, aloyi zitsulo, etc. Mtundu uliwonse chuma ndi yakonzedwa yake ya miyezo ndi specifications.
Miyezo yopangira:
Kupanga kwa Submerged-Arc Welded Steel Pipes kungatsatire milingo yeniyeni yokhazikitsidwa ndi mabungwe monga American Petroleum Institute (API), American Society for Testing and Materials (ASTM), kapena mabungwe ena apadziko lonse kapena apadziko lonse lapansi motere: API 5L, API 5CT, ASTM 53, EN10217, DIN 2458, IS 3589, GB/T3091, GB/T9711, EN10217, EN10219

Zoyenera Kugwiritsidwira Ntchito: Mapaipi owotcherera aatali amathanso kugawidwa malinga ndi momwe angagwiritsire ntchito, monga mapaipi amafuta ndi gasi, kamangidwe kake, kapena kugwiritsidwa ntchito m'mafakitale. Onetsetsani kuti mukunena za milingo ndi magawo omwe amagwirizana ndi zomwe mukufuna, chifukwa zitha kusiyanasiyana kutengera mafakitale ndi dera.
