Mitundu Yopangira

Mitundu Yopangira Chitoliro cha API 5L
Muyezo wa API 5L umakhudza zonse ziwirimapaipi achitsulo opanda msoko komanso olumikizidwa.

Mitundu ya Chitoliro Cholumikizidwa:

ERW (Kuwotcherera Kotsutsana ndi Magetsi):Yoyenera mapaipi ozungulirapansi pa mainchesi 24, yomwe imagwiritsidwa ntchito kwambiri pakugwiritsa ntchito mapaipi wamba.

DSAW / SAW (Kuwetsa Arc Yokhala ndi Miyendo iwiri / Kuwetsa Arc Yokhala ndi Miyendo iwiri):Njira ina m'malo mwa ERW yamapaipi akuluakulu okulirapo, kuonetsetsa kuti ma weld amphamvu a longitudinal apangidwa.

FAQ

Q1: Kodi zofunikira ndi magiredi a mapaipi anu a API 5L ndi ziti?

A: Tikhoza kupereka mapaipi a API 5L PSL1 ndi PSL2 Giredi B, X42, X52, X56, X60, X65, X70, X80. Timapereka zinthu zopanda msoko komanso zolumikizidwa (ERW, SAW, DSAW, LSAW, SSAW, HSAW) zokhala ndi kukula kuyambira 1/2” mpaka 40” komanso makulidwe a khoma kuyambira SCH 10–SCH 160.

Q2: Kodi mungapange kutalika kosiyana ndi mtundu womaliza?

A: Inde. Mapaipi amapezeka mu SRL (Single Random Length), DRL (Double Random Length), 20FT, 40FT kapena kutalika kosinthidwa. Malekezero amatha kukhala opindika kapena osalala malinga ndi zofunikira za polojekiti.

Q3: Kodi muli ndi katundu woti mutumize mwachangu?

A: Inde, tili ndi chitoliro chachikulu cha API 5L chogulitsa chomwe chimatumiza mwachangu, nthawi yotsogolera ndi yochepa.

Q4: Kodi mapaipi anu ali ndi satifiketi?

Mapaipi okhala ndi satifiketi yonse ya API 5L kuphatikiza MTR angagulidwe pamodzi. Kuyesa kosawononga (radiography, ultrasound) kumachitika kuti kutsimikizire mtundu.

Q5: Mumapereka phukusi lanji?

A: Kumangirira kwabwino kwa ma CD ndi waya wachitsulo. Ma CD osankha omwe safuna dzimbiri kapena okonzedwa mwamakonda amapezeka kuti atumizidwe kumayiko ena kapena pakufunika ntchito zapadera.
