Zofunikira za Elongation: Malinga ndi muyezo

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 A672 B60/B70/C60/C65/C70 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.

Mawonekedwe a ASTM A672 B60/B70/C60/C65/C70 LSAW Chitoliro Chachitsulo cha Carbon:

B. Nambala yodziwika (tsiku la chaka kapena lofunikira).
C. Kukula (OD, WT, kutalika).
D. Gulu (A kapena B).
E. Mtundu wa chitoliro(F, E, kapena S).
F. Kuthamanga kwa mayeso (chitoliro chopanda chitsulo chokha).
G. Nambala ya Kutentha.
H. Zambiri zowonjezera zomwe zafotokozedwa muzogula.

Kulongedza kwa ASTM A672 B60/B70/C60/C65/C70 LSAW Chitoliro Chachitsulo cha Carbon:

● Chitoliro chopanda kanthu kapena Chophimba Chakuda / Varnish / Epoxy / 3PE zokutira (molingana ndi zofuna za kasitomala);

● 6 "ndi pansi m'mitolo ya thonje ziwiri;

● Zonse zimathera ndi otetezera mapeto;

● Mapeto osavuta, malekezero a bevel (2"ndi pamwamba pa bevel, digiri: 30 ~ 35 °), ulusi ndi kugwirizana;

● Kulemba chizindikiro.
