Mumunda wekuchera mafuta uye tsime remafuta, yakakwira-frequency yemagetsi kuramba welded casing (inonzi ERW casing) kana ichienzaniswa neseamless casing yakakwira dimensional kurongeka, weld toughness, anti-extrusion ye-high-performance, uye yakaderera mutengo zvakanakira, izvo. rave richishandiswa zvakafara munyika dzokumwe, uye rakawana migumisiro yakanaka.

Hunhu hweERW casing (inofananidzwa nesina musono casing)
High dimensional kurongeka: ERW casing ichishandisa mechanical sizeing process mushure mekuumbwa, precision seamless casing yakawedzera saizi yayo (kunze kwedhayamita, ukobvu hwemadziro, kutenderera, zvichingodaro), uye kutsauka kwayo kwekunze kwedhayamita isingadariki ± 0 Avhareji .5%. Zvakadai zvakaburitswa neNippon Steel 6244.5 n'un ERW casing ukobvu hwakajairwa kutsauka kwe <0.10 mill inoenderana musono casing standard deviation yaive 0.41 mill.

Yakanaka weld kusimba: ERW casing kugadzira process inogona kuvimbiswa kuwana C, S uye P zvemukati zvakaderera muchikamu chesangano uye hwaro hwezvinhu zvesimba rakakwirira, kusimba kwepamusoro kweweld, iyo weld kusimba isina musono sleeve kuitira kuti sleeve chubhu. .

Anti-extrusion the anti-knock properties: simba rakakwirira 30% kusvika 40% kana ichienzaniswa neiyo API yakafanana casing casing, ERW casing anti-extrusion, anti-knock properties (internal pressure) inenge 50% yakakwirira.

Tekinoroji yepamusoro, kudzora kwemhando yechigadzirwa: ERW sleeve base simbi yekudzora yakakungurutswa coil, isotropic, 100% isinga paradza bvunzo.

Mutengo wakaderera: uchienzaniswa neyakafanana casing casing, ERW casing 5% kusvika 10% yakaderera mutengo, yakanyanya kunaka, yakakwirira dhigirii yemakanika uye otomatiki, yakaderera kushandiswa kwesimba uye kugadzira; ERW casing yakapedza chigadzirwa chiyero che93% kusvika 98%, uye isina musono casing yakapedza chigadzirwa mwero we85% kusvika 90%; ERW inotora mari yese yeprojekiti yakaderera ne40% pane iyo isina musono casing chirongwa.

Hunhu hwehunyanzvi hweERW casing
(1) Kusarudzwa kwezvinhu zvakasvibirira zvinodzorwa coil, iyo yakasimba kudzora zviri mukati S uye P, uye kabhoni yakaenzana, kazhinji W (S) ≤ 0.015%, iyo kabhoni yakaenzana ≤ O. 25%. Uye kushandiswa kweiyo micro-alloying element seNb, V, Ti, uye cu inovandudza kuoma kwesimbi kuvandudza weldability uye corrosion resistance.

(2) Gobvu coil mushure memupendero milling kurapwa, inogona kuderedza welding burrs inokonzerwa nekupisa kwenzvimbo uye oxidation.

(3) Inoshandiswa zvakanyanya spiral looper yekuenderera mberi kugadzirwa, hapana roll-kune-vhoriyamu batch kugadzirwa kunokonzerwa nekumira kwewelding, zvichikonzera kutangazve welding, welding ikozvino, kusagadzikana kwemagetsi nekuda kwehurema hwechigadzirwa.

(4) Inowanzoshandiswa muhurumende-ye-the-art hydraulic kubviswa kweburrs process, casing inner burr height control 1.14 NLNL.

(5) Strict welding parameters, kusanganisira simba rekuisa, welding V-yakaita angle, welding speed, welding tembiricha kutonga. Welding tembiricha nepamusoro-frequency welding yekumhanyisa yeyakavharwa loop simba rekudzora, kudzora kushanduka kweisingasviki ± 5 ℃.

(6) Kusimbiswa kwe-post-weld heat treatment, kuburikidza ne-post-weld heat treatment kuvandudza sangano uye kushushikana kwemukati weld zone.

(7) Kugadzirwa kwesimba repamusoro uye saizi yeyuniti, kudzikisa hombe kunyatso kupedzwa.

(8) Kune weld uye simbi seye-yese-mutsara kana isina-mutsara isiri-inoparadza yekuyedza, panguva uye yakaringana yekuona zvikanganiso, kuitira kugadzirisa panguva yakakodzera nzira yekugadzira kuve nechokwadi chemhando yechigadzirwa.
