Welded Simbi Pipe: Yakakwana Nhungamiro Kuve nechokwadi Yakanaka Uye Yakavimbika Kubatanidza

suma:

Mumaindasitiri ese, mapaipi esimbi anoshandiswa zvakanyanya pakusimba kwawo, kusimba, uye kuita zvakasiyana-siyana.Kana uchibatanidza mapaipi esimbi, welding ndiyo nzira inosarudzwa.Welding inogadzira hukama hwakasimba hunogona kumirisana nekumanikidza kwakanyanya, zvichiita kuti ive yakakosha muzvikamu zvakaita sekuvaka, oiri uye gasi, uye kugadzira.Mune ino blog, isu tinonyura mukukosha kwesimbi pombi welding uye nekupa dhairekitori rakazara rekuve nechokwadi chekubatana kwakanaka uye kwakavimbika.

Mechanical Property

Kuumbwa Kwemakemikari

Hydrostatic Test

Hurefu hwega hwega hwepombi huchaedzwa nemugadziri kune hydrostatic pressure iyo inoburitsa mumadziro epombi kushushikana kusingasviki 60% yeiyo yakataurwa kushomeka kwegoho pakupisa kwekamuri.Kudzvanywa kunozotemwa neinotevera equation:
P=2St/D

Kusiyana Kunobvumirwa Muhuremu uye Zviyero

Hurefu hwega hwega hwepombi huchayerwa hwakasiyana uye huremu hwayo hahuzosiyane kupfuura 10% pamusoro kana 5.5% pasi pehuremu hwayo hwekufungidzira, huchiverengerwa uchishandisa kureba kwayo uye uremu hwayo pahurefu hweyuniti.
Iyo dhayamita yekunze haifanire kusiyana kupfuura ± 1% kubva kune yakatsanangurwa yekunze dhayamita.
Ukobvu hwemadziro chero nguva haufanire kupfuura 12.5% ​​pasi peiyo yakataurwa madziro ukobvu.

Urefu

Single random urefu: 16 kusvika 25ft (4.88 kusvika 7.62m)
Hurefu hwakapetwa kaviri: pamusoro pe25ft kusvika 35ft (7.62 kusvika 10.67m)
Hurefu hwakafanana: musiyano unobvumidzwa ±1in

Ends

Mirwi yepombi inofanira kuiswa pachena, uye maburi ari kumigumo anofanira kubviswa.
Kana iyo pombi inopera yakatsanangurwa kuve bevel inopera, kona ichave 30 kusvika 35 degree

1. Nzwisisa mapaipi esimbi:

 Mapaipi esimbihuya muhukuru hwakasiyana, maumbirwo uye zviwanikwa, chimwe nechimwe chakakodzera kune chaiwo maapplication.Iyo inowanzogadzirwa nekabhoni simbi, simbi isina tsvina kana alloy simbi.Carbon simbi mapaipi anoshandiswa zvakanyanya nekuda kwekukwanisa kwawo uye simba, nepo simbi isina tsvina pombi inopa yakanakisa corrosion resistance.Munzvimbo dzekushisa kwepamusoro, alloy simbi mapaipi anosarudzwa.Kunzwisisa marudzi akasiyana-siyana epombi yesimbi kuchabatsira kusarudza yakakodzera welding sarudzo.

2. Sarudza welding process:

Kune akasiyana maitirwo emagetsi anoshandiswa kujoina simbi pombi, kusanganisira arc welding, TIG (tungsten inert gasi) welding, MIG (simbi inert gasi) welding, uye yakanyudzwa arc welding.Sarudzo yewelding process inoenderana nezvinhu zvakaita semhando yesimbi, pombi dhayamita, nzvimbo yewelding uye dhizaini yakabatana.Imwe neimwe nzira ine zvayakanakira uye zvinogumira, saka kusarudza yakanyanya kufanira maitiro ekushandisa kwaunoda kwakakosha.

3. Gadzirira pombi yesimbi:

Kugadzirira kwepombi kwakakodzera kusati kwave kusungirirwa kwakakosha pakuwana mubatanidzwa wakasimba uye wakavimbika.Zvinosanganisira kuchenesa nzvimbo yepombi kubvisa chero ngura, chikero kana tsvina.Izvi zvinogona kuitwa nemichina yekuchenesa nzira dzakadai sekukwesha waya kana kugaya, kana kushandisa mishonga yekuchenesa.Pamusoro pezvo, kurira kwepombi kupera kunogadzira groove yakaita V inobvumira kupinda zviri nani kweiyo yekuzadza zvinhu, nekudaro kufambisa nzira yewelding.

4. Welding tekinoroji:

Iyo welding nzira inoshandiswa zvakanyanya inokanganisa kunaka kwejoinhi.Zvichienderana nemaitiro ekuisa welding anoshandiswa, ma paramita akakodzera akadai sewelding ikozvino, voltage, kumhanya kwekufamba uye kupisa kupinza kunofanirwa kuchengetedzwa.Unyanzvi uye ruzivo rweanopisa anoitawo basa rakakosha mukuwana yakanaka uye isina kukanganisa-isina weld.Matekinoroji akadai seakakodzera electrode kushanda, kuchengetedza arc yakagadzikana, uye kuona yakaringana yekudzivirira gasi kuyerera kunogona kubatsira kuderedza hurema hwakadai seporosity kana kushomeka kwefusion.

5. Post-weld kuongorora:

Kana welding yapera, zvakakosha kuita post-weld inspection kuti uone chero kukanganisa kana kukanganisa kunogona kukanganisa kuvimbika kwejoint.Nzira dzisiri dzekuparadza dzekuyedza dzakadai sekutarisa kwekuona, dhayi inopinda bvunzo, magineti particle kuyedza kana ultrasonic bvunzo inogona kushandiswa.Ongororo idzi dzinobatsira kuona matambudziko angangoitika uye kuona kuti majoini akaiswa welded anosangana nezvinodiwa.

Mukupedzisa:

 Simbi Pipe Yekusvinainoda kunyatsotariswa uye kuita kwakaringana kuti ive nechokwadi chekubatana kwakanaka uye kwakavimbika.Nekunzwisisa marudzi akasiyana-siyana epombi yesimbi, kusarudza nzira yakakodzera yekugadzira, kugadzirira zvakakwana pombi, kushandisa nzira dzakakodzera dzekugadzirisa, uye kuita post-weld inspections, unogona kuwana welds yakasimba uye yepamusoro-soro.Izvi zvinobatsirawo kuvandudza kuchengetedzwa, kuvimbika uye hupenyu hwebasa hwemapombi esimbi mumashandisirwo akasiyana siyana uko ari zvikamu zvakakosha.
