Njira Yopangira

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.
