Maitiro Ekugadzira

Maitiro ekugadzira Longitudinal Submerged-arc Welded (LSAW) Pipe ndeekuti:

Kuongorora maplate eUltrasonic → kugaya mupendero → kukotama → kugadzira → Kugadzirisa usati waisa → Kugadzirisa mukati → Kugadzirisa kunze → Kuongorora kweUltrasonic → Kuongorora kweX-ray → Kuwedzera → bvunzo ye hydraulic →l. Kugadzirisa → Kuongorora kweUltrasonic → Kuongorora kweX-ray → Kuongorora kweX-ray → Kuongorora kwezvimedu zvemagnetic pamucheto wechubhu

Kusiyana Kunobvumidzwa muHuremu neMakuriro

1. Dhayamita Yekunze - Zvichibva pakuyera kwakatenderedza ±0.5% yedhayamita yekunze yakatarwa.

2. Kusiyana-kwe-kutenderera-Musiyano uripo pakati pemadhayamita makuru nemadiki ekunze.

3. Kurongeka-Kushandisa tambo yakatwasuka ine 3m (10 ft) yakaiswa kuitira kuti magumo ese ari maviri abatane nepombi, 1/8 in. (3mm).

4. Ukobvu - Ukobvu hwemadziro hushoma pane chero nzvimbo mupombi hahufanirwe kupfuura 0.01 in. (0.3mm) pasi peukobvu hwakatarwa.

5. Kureba kwemativi asina kugadzirwa kunofanira kunge kuri mukati me -0,+1/2 in. (-0,+13mm) kubva pane zvakatarwa. Kureba kwemativi ane kugadzirwa kunofanira kunge kwakabvumiranwa pakati pemugadziri nemutengi.

Kuedzwa kweMechanical kweASTM A671 LSAW Carbon Steel Pipe:

Kuedzwa kweKusimba—Hunhu hwekusimba kwekubatana kwesimbi yakasungirirwa hunofanira kuzadzisa zvinodiwa zvishoma kuti simbi yesimbi isimbiswe zvakanyanya.

Miedzo yekukombama inotungamirwa ne transverse-guided weld-belt —Muedzo wekukombama uchagamuchirwa kana pasina mitswe kana zvimwe zvikanganiso zvinopfuura 1/8 in. (3mm) chero kupi zviripo musimbi yekukombama kana pakati pesimbi yekukombama nesimbi yepasi mushure mekukombama.

Kuongorora neRadio-graphic - Hurefu hwese hwe weld yega yega yekirasi X1 neX2 hunofanira kuongororwa neradiographic zvichienderana uye zvinosangana nezvinodiwa neASME Boiler and Pressure Vessel Code, Chikamu chechinomwe, ndima UW-51.
