Welded Steel Pipi: Nhungamiro Yakakwana yekuita kuti uve nechokwadi chakakosha uye chakavimbika kubatana

Suma:

Kuyambuka maindasitiri, mapepa esimbi anoshandiswa zvakanyanya nekuda kwesimba ravo, kusimba, uye kusiyana-siyana. Kana uchijoinha mapepa esimbi, Welding ndiyo nzira yavanofarira. Welding inogadzira hukama hwakasimba hunokanganisa zvakanyanya kudzvinyirira, zvichiita kuti zvive zvakakosha mumatareji akadai sekuvaka, mafuta negesi, uye kugadzira. Mune ino blog, isu tichapwanya mukukosha kweiyo pombi yelding uye kupa nhungamiro yakazara yekuita kuti kuve nekubatikana uye kuvimbika

Hydrostatic test

Kureba kwepepe kuchaidzwa nemugadziri kune hydrostatic kumanikidza kuchagadzira madziro kushushikana kwekushaiwa makumi matanhatu muzana yeiyo yakasarudzika shuwa simba rekubereka tembiricha. Dzvinyiriro ichatsanangurwa neiyo inotevera equation:
P = 2st / d

Zvinotenderwa kusiyana kwehuremu uye zviyero

Kureba kwega kwega kwembwa kucharemerwa zvakasiyana uye kurema kwayo hakuzopindirane kupfuura gumi muzana pamusoro kana 5.5% pasi pehuremu hwayo uye huremu hwayo uye huremu hwayo pahurefu.
Iyo yekunze dhisiki haizosiyane kupfuura ± 1% kubva pane yakatarwa zita rekunze kunze kwedhimoni.
Kukudza kwemadziro chero nguva hakusi kupfuura gumi nemairi% pasi peiyo yakataurwa madziro.

Kureba

Hurefu hwakasarudzika: 16 kusvika 25ft (4.88 kusvika 7.62m)
Kaviri akareba kureba: Pamusoro pe25ft kusvika ku15ft (7.62 kusvika 10.67m)
Yunifomu Yakareba: Inotenderwa Kusiyana ± 1in

Magumo

Pipe Piles ichagadzirwa nebani magumo, uye burrs kumahombekombe
Kana iyo pombi yekupedzisira yakatsanangurwa kuve yechiodzwa magumo, iyo angle ichave nemakumi matatu kusvika ku35 degree

1. Nzwisisa pombi dzeimba:

 Masimbi mapipiHuya mumhando dzakasiyana-siyana, chimiro uye zvigadzirwa, imwe neimwe yakakodzera kune chaiyo yekushandisa. Ivo vanowanzogadzirwa necarbon simbi, simbi isina tsvina kana alloy simbi. Carbon zvibayiro zvibayiro zvinoshandiswa zvakanyanya nekuda kwekukwanisa kwavo uye kusimba, nepo pombi dzesimbi dzisimba dzinopa simba rakanakisa rekushora. Munzvimbo dzakakura dzekushisa Kunzwisisa mhando dzakasiyana dzebhandi pombi kuchabatsira kuziva yakakodzera yelding sarudzo.

2. Sarudza Welding maitiro:

Kune akasiyana siyana elding maitiro anoshandiswa kujoina pombi, kusanganisira Arc Welding, Tig (tungsten inert gasi) Welding Sarudzo yeAlding maitiro inoenderana nezvinhu zvakadai sesimbi mhando, pombi diameter, Welding nzvimbo uye dhizaini. Imwe neimwe nzira ine zvakanakira uye zvisingakwanisi, saka kusarudza maitiro akakodzera kwazvo eiyo application yaunoda ndeye yakakosha.

3. Gadzirira pombi yesimbi:

Kugadzirira kwepombi kwakakodzera usati wabereka kuongorora kuti uzadzise simba rakasimba uye rakavimbika. Izvo zvinosanganisira kuchenesa iyo pombi yekubvisa chero ngura, chiyero kana zvinangwa. Izvi zvinogona kuitwa nemaitiro ekuchenesa ekuchenesa nzira dzakadai seya waya yekugezesa kana kugeda, kana nekushandisa makemikari ekuchenesa. Pamusoro pezvo, chamfering iyo pombi inogadzira v-yakavezwa groove inobvumidza kupinzwa kuri nani kweiyo floller yezvinhu, nekudaro uchiita kuti tiratidze maitiro.

4. Welding tekinoroji:

Maitiro ekutambisa anoshandiswa zvakanyanya kukanganisa hunhu hwejoini. Zvichienderana nemaitiro eldinging akashandiswa, ma parameter akakodzera seanoita seanobata nazvino, voltage, kumhanya kwekufambisa uye kupisa kupisa kunofanirwa kuchengetwa. Unyanzvi uye ruzivo rweWalder zvakare zvinokosha nebasa rekuzadzisa rakanaka uye rakaremara-remahara. Nhungamiro dzakadai seyakakodzera Electrode kushanda, uye ichiramba iri arc inoyerera gasi yekuyerera inogona kubatsira kuderedza hurema senge porosity kana kushayikwa kwekupokana.

5. Post-Weld kuongororwa:

Kana iyo Welating yakwana, inokosheswa kuitisa kuongororwa-weld-weld kuwona chero zvikanganiso kana zvikanganiso zvinogona kukanganisa kutendeka kwejoini. Nzira dzisiri-dzinoparadza dzinoedzwa sekuongororwa kwekuona, Dye penetrant kuongororwa, magineti tarisiro yekuyedza kana ultrasonic bvunzo inogona kushandiswa. Aya ongororo anobatsira kuona matambudziko angangove anokwanisa uye ave nechokwadi chekuti majoini akatarisana anosangana anodikanwa.

Mukupedzisa:

 Simbi pombi yeWeldinginoda kunyatsofungisisa uye kuuraya kwakaringana kuve nechokwadi chekubatana uye chakavimbika. Nokunzwisisa mhando dzakasiyana dzebato simbi, uchisarudza yakakodzera testing maitiro, achigadzirira zvizere pombi, achishandisa nzira dzakakodzera dzeMulting, uye kuita ongororo-weld-weld ongororo, iwe unogona kuwana yakasimba uye yakakwirira-yemhando yemhando yepamusoro. Izvi zvinobatsira kuvandudza kuchengetedzeka, kuvimbika uye kwebasa rebasa renzvimbo yechibage mumidziyo dzakasiyana siyana uko kune zvikamu zvakakosha.
