Njira yopangira Pipe ya Longitudinal Submerged-arc Welded(LSAW) ili motere:

Akupanga mbale kufufuza → m'mphepete mphero → chisanadze kupinda → kupanga → Pre-kuwotcherera → kuwotcherera mkati → kuwotcherera kunja → Akupanga kuyendera → X-ray anayendera → Kukulitsa → hydraulic mayeso →l.Chamfering → Akupanga kuyendera → X-ray anayendera → maginito tinthu anayendera pa chubu mapeto

Kusiyanasiyana Kovomerezeka Pakulemera ndi Makulidwe

1. Diameter ya Kunja-Kutengera muyeso wozungulira ± 0.5% wa m'mimba mwake womwe watchulidwa.

2. Out-of-Roundness-Kusiyana pakati pa zazikulu ndi zazing'ono zakunja diameters.

3. Kuyanjanitsa-Kugwiritsa 10 ft (3m) kuwongola anaika kuti malekezero onse kukhudzana ndi chitoliro, 1/8 mu. (3mm).

4. Makulidwe - Makulidwe ochepa a khoma nthawi iliyonse mu chitoliro sichiyenera kupitirira 0.01 in. (0.3mm) pansi pa makulidwe otchulidwa mwadzina.

5. Utali wokhala ndi malekezero opanda makina uzikhala mkati mwa -0+1/2 mkati. (-0+13mm) kuchokera pamenepo.Kutalika kokhala ndi malekezero opangidwa ndi makina kudzakhala monga momwe adagwirizana pakati pa wopanga ndi wogula.

Kuyesa Kwamakina kwa ASTM A671 LSAW Chitoliro Chachitsulo cha Carbon:

Kuyesa Kwamphamvu-Zomwe zimasunthika zolumikizirana zowotcherera zimakwaniritsa zofunikira kuti pakhale mphamvu yolimba yazinthu zomwe zatchulidwa.

Mayeso opindika-wowongolera-wokhotakhota -Mayeso opindika adzakhala ovomerezeka ngati palibe ming'alu kapena zolakwika zina zopitirira 1/8 mkati (3mm) kumbali iliyonse zilipo muzitsulo zowotcherera kapena pakati pa zitsulo zowotcherera ndi zitsulo zoyambira pambuyo popindika.

Mayeso a Radio-graphic-Utali wonse wa weld iliyonse ya kalasi X1 ndi X2 udzawunikidwa mozama motsatira ndikukwaniritsa zofunikira za ASME Boiler and Pressure Vessel Code, Gawo lachisanu ndi chiwiri, ndime UW-51.

Maonekedwe a ASTM A671 LSAW Chitoliro Chachitsulo cha Carbon:

Dzina kapena chizindikiro cha wopanga
Nambala yachidziwitso (chaka cha chaka kapena chofunikira)
Kukula (OD, WT, kutalika)
Gulu (A kapena B)
Mtundu wa chitoliro (F, E, kapena S)
Kuthamanga kwa mayeso (chitoliro chopanda chitsulo chokha)
Nambala Yotentha
Zowonjezera zilizonse zomwe zafotokozedwa muzogula.

Kuyitanitsa zambiri

Kuchuluka (mapazi, mamita, kapena kuchuluka kwa utali)
Dzina la zinthu (chitsulo chitoliro, magetsi maphatikizidwe welded)
Nambala yodziwika
Makalasi ndi kalasi
Kukula (kunja kapena mkati mwake, wamba kapena makulidwe ochepa a khoma)
Utali (mwachindunji kapena mwachisawawa)
Kumaliza kumaliza
Zosankha zogula
Zofunikira zowonjezera, ngati zilipo.
