Njira Yopangira

Njira yopangira chitoliro cha Longitudinal Submerged-arc Welded (LSAW) ndi iyi:

Kufufuza mbale ya Ultrasonic → kugaya m'mphepete → kupindika koyambirira → kupanga → Kuwotcherera koyambirira → Kuwotcherera mkati → Kuwotcherera kwakunja → Kuyang'anira Ultrasonic → Kuyang'anira X-ray → Kukulitsa → mayeso a hydraulic → l. Kuwotcherera → Kuyang'anira Ultrasonic → Kuyang'anira X-ray → Kuyang'anira tinthu ta maginito kumapeto kwa chubu

Kusiyanasiyana Kovomerezeka kwa Kulemera ndi Miyeso

1. M'mimba mwake wakunja - Kutengera muyeso wozungulira ± 0.5% ya m'mimba mwake wakunja womwe watchulidwa.

2. Kusiyana kwa ma diameter akunja ozungulira ndi ang'onoang'ono.

3. Kulinganiza - Kugwiritsa ntchito m'mphepete wowongoka wa 3m (10 ft) womwe wayikidwa kotero kuti malekezero onse awiri agwirizane ndi chitoliro, 1/8 in. (3mm).

4. Kukhuthala - Kukhuthala kwa khoma kocheperako pamalo aliwonse mu chitoliro sikuyenera kupitirira 0.01 inchi (0.3mm) pansi pa makulidwe odziwika.

5. Kutalika kwa zinthu zomwe sizinagwiritsidwe ntchito kuyenera kukhala mkati mwa -0, 1/2 inchi (-0, 13mm) kuchokera pa zomwe zafotokozedwa. Kutalika kwa zinthu zomwe zinagwiritsidwa ntchito kuyenera kukhala monga momwe zavomerezedwera pakati pa wopanga ndi wogula.

Mayeso a Makina a Chitoliro cha Chitsulo cha Kaboni cha ASTM A671 LSAW LSAW:

Kuyesa Kupsinjika—Makhalidwe opingasa a cholumikizira cholumikizidwacho ayenera kukwaniritsa zofunikira zochepa kuti chikhale ndi mphamvu yolimba kwambiri ya zinthu zomwe zatchulidwazo.

Mayeso opindika otsogozedwa ndi weld —Mayeso opindika adzakhala ovomerezeka ngati palibe ming'alu kapena zolakwika zina zopitirira 1/8 inchi (3mm) mbali iliyonse zomwe zilipo mu chitsulo chopindika kapena pakati pa weld ndi chitsulo choyambira mutapindika.
