Mapaipi a Api 5l Line Giredi B Mpaka X70 Od Kuyambira 219mm Mpaka 3500mm

Kufotokozera Kwachidule:

Chidule ichi ndi kupereka muyezo wopanga mapaipi kuti azitha kutumiza madzi, gasi ndi mafuta m'mafakitale amafuta ndi gasi wachilengedwe.

Pali magawo awiri a zinthu zomwe zagulitsidwa, PSL 1 ndi PSL 2, PSL 2 ili ndi zofunikira zofunika pa carbon equivalent, notch strength, maximum voeld strength ndi tensile strength.

Giredi B, X42, X46, X52, X56, X60, X65, X70 ndi X80.

Cangzhou Spiral Steel pipes group co.,ltd imapereka mapaipi a SAWH omwe ali ndi kalasi kuyambira API B mpaka X70, tinalandira satifiketi ya API 5L zaka zapitazo ndipo tsopano mapaipi athu omwe amagwiritsidwa ntchito kwambiri ndi CNPC, CPECC pa ntchito zawo za mapaipi.

Mayeso a Hydrostatic

kufotokozera kwa malonda1

Chitolirocho chiyenera kupirira mayeso a hydrostatic popanda kutuluka kudzera mu msoko wa weld kapena thupi la chitolirocho.
Zolumikizira siziyenera kuyesedwa ndi madzi, bola ngati magawo a chitoliro chomwe chimagwiritsidwa ntchito polemba zolumikizira adayesedwa bwino ndi madzi asanayambe ntchito yolumikizira.

Kutsata:
Pa chitoliro cha PSL 1, wopanga ayenera kukhazikitsa ndikutsatira njira zolembedwa zosamalira:
Kuzindikira kutentha mpaka mayeso aliwonse okhudzana ndi chmic atachitika ndipo kutsatira zofunikira zomwe zafotokozedwazo kukuwonetsedwa.
Kuzindikiritsa kwa gawo loyesera mpaka mayeso aliwonse okhudzana ndi makina atatha ndipo kutsatira zofunikira zomwe zafotokozedwazo kuwonetsedwe
Pa chitoliro cha PSL 2, wopanga ayenera kukhazikitsa ndikutsatira njira zolembedwa kuti asunge chizindikiro cha kutentha ndi chizindikiro cha chitoliro choyesera cha chitolirocho. Njira zoterezi ziyenera kupereka njira zotsatirira kutalika kulikonse kwa chitolirocho ku chitoliro choyenera choyesera ndi zotsatira zoyeserera za mankhwala.
