Maitiro Ekugadzira Pipe Yakanyudzwa Yakadzika Mumvura Yenguva refu:

Pombi yeLSAWinoshandisa tekinoroji yekuwedera yearc iri pasi pemvura, ichishandisa welding yekuzadza, kudzivirira flux yakavigwa arc.

LSAW ipfupiso yeChirungu yepipi yesimbi yakasungirirwa yakatwasuka ine arc. Maitiro ekugadzira pipi yesimbi yakasungirirwa yakatwasuka ine arc inosanganisira tekinoroji yekugadzira JCOE, tekinoroji yekubatanidza arc yakasungirirwa yakatwasuka ine arc uye tekinoroji yekugadzira UOE.

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

Muedzo wekukombama—Pombi yakareba zvakakwana inofanira kumira yakakotama ichitonhora kusvika pa90° yakatenderedza mandrel yakatenderera.

Kuedza kutetepa-Kunyangwe bvunzo dzisingadiwi, pombi dzinofanira kukwanisa kusangana nezvinodiwa zvebvunzo yekupfava.

Kuedzwa kwemvura-static—kunze kwekunge zvichibvumirwa, kureba kwese kwepombi kunofanirwa kuongororwa ne hydro-static pasina kubuda kwemvura nepamadziro epombi.

Kuedza kwemagetsi kusingaparadze-Senzira yekutsiva bvunzo ye hydro-static, muviri wese wepombi yega yega unofanira kuyedzwa nebvunzo yemagetsi isingaparadze. Kana bvunzo yemagetsi isingaparadze ikaitwa, kureba kwacho kunofanira kunyorwa nemabhii ekuti "NDE"

Pombi isina chinhu, chifukidziro chitema (chakagadziriswa);
Migumo yese ine zvidziviriro zvekupedzisira;
Mugumo usina kujeka, mugumo we bevel;

Kushivirira kwedhayamita yekunze, ukobvu hwemadziro, kureba uye huremu:

Dhayamita yekunze	Dhayamita yekunze yemapombi haifanirwe kusiyana kupfuura ±1% kubva padhayamita yekunze yakatarwa.
Ukobvu hwemadziro	Ukobvu hwemadziro chero nguva hahufanirwe kupfuura 12.5% pasi peukobvu hwemadziro hwakatarwa.
Hurefu	Mapombi emapaipi anofanira kupihwa muhurefu hwakasiyana-siyana, hurefu hwakapetwa kaviri, kana hurefu hwakafanana sezvakatsanangurwa muodha yekutenga, zvichienderana nemiganhu inotevera:	Hurefu husina kurongeka	16 kusvika 25ft (4.88 kusvika 7.62mm), inch

		Hurefu hwakafanana	kureba sezvakatsanangurwa nekuchinja kunobvumidzwa kwe ±1 in.
Huremu	Kureba kwese kwepombi yepombi kunofanira kuyerwa kwakasiyana uye huremu hwayo hahufanirwe kusiyana ne15% pamusoro kana 5% pasi pehuremu hwayo hwepfungwa, zvichiverengerwa uchishandisa hurefu hwayo nehuremu hwayo pahurefu hweyuniti.
