Hlaziya ukufana nomehluko phakathi kwezindololwane ezishiselwe nezindololwane ezifojiwe.

Indololwane efojiwe wukufakwa kwepayipi okushintsha isiqondiso sepayipi.Njengoba yakhiwe, ikwazi ukumelana nezingcindezi eziphakeme ezifika ku-9000LB, ngakho abanye abantu bayibiza ngendololwane enengcindezi ephezulu.

Izindololwane zokushisela zingasikwa futhi zishiselwe emapayipini noma kumapuleti ensimbi, anezinhlobonhlobo zokucaciswa.Inombolo yokugoba kanye nerediyasi egobayo inqunywa ngokukhululekile umenzi.I-welding bend ayibushelelezi kakhulu, futhi i-radius egobayo yakho yomibili ayinkulu, imvamisa icishe ibe kabili ububanzi bepayipi.

Izindololwane ezishiselwefuthiizindololwane ezakhiweizingxenye ezimbili ezivame ukusetshenziswa ezixhumayo ezinhlelweni zamapayipi, futhi zinokufana nokuhluka okuthile ezinqubweni zokukhiqiza, ukusebenza, kanye nezimo ezisebenzayo.

1. Inqubo yokukhiqiza:

• Indololwane yokushisela:

Ukukhiqizaindololwane weldingngokuvamile isebenzisa inqubo yokushisela, ehlanganisa ukugoba ipayipi nokulungisa izingxenye zokuxhuma nge-engeli oyifunayo ngobuchwepheshe bokushisela.Izindlela zokushisela ezijwayelekile zifaka i-arc welding, i-TIG welding, i-MIG welding, njll.

• Indololwane eyakhiwe:

Inqubo yokukhiqiza indololwane eyenziwe ngomgunyathi ihlanganisa ukubumba ukuma kwendololwane ngokufaka i-block block yensimbi ngaphansi kwezinga lokushisa eliphezulu kanye nokucindezela okukhulu.Lokhu kuvame ukudinga izinyathelo zenqubo ezengeziwe, njengokubumba, ukuklama isikhunta, njll.

2. Ukusebenza:

• Indololwane yokushisela:

Ngenxa yokubandakanyeka kwezindawo ezithintekile ukushisa ngesikhathi sokushisela, kungase kubangele izinguquko ezithile ezimpahleni ezibonakalayo.Ngaphezu kwalokho, i-weld seam yama-elbows ashiselwe ingase ibe iphuzu elibuthakathaka futhi ukunakwa okukhethekile kufanele kukhokhwe kukhwalithi yokushisela.

• Indololwane eyakhiwe:

Ngesikhathi senqubo yokubumba, ukwakheka okusanhlamvu kwensimbi kuvame ukuminyene, ngakho ukusebenza kwendololwane ehlanganisiwe kungase kufane kakhulu, futhi ngokuvamile awekho ama-welds.

3. Izimo ezisebenzayo:

• Indololwane yokushisela:

Ilungele amapayipi amancane obubanzi, ikakhulukazi ezimeni lapho ukufakwa okusheshayo nezindleko eziphansi kuyadingeka.Ivame ukutholakala ezimbonini ezifana nezokwakha, ukwakha imikhumbi, kanye nokucubungula ukudla.

• Indololwane eyakhiwe:

Ifanele izidingo zokucindezela okuphezulu, izinga lokushisa eliphezulu noma ukusebenza okuphezulu kwezindololwane, njengezinkambu zezimboni ezifana namakhemikhali, i-petroleum, igesi yemvelo, njll.

4. Ukubukeka nobukhulu:

• Izindololwane zokushisela:

Kulula ukufeza ubujamo nobukhulu obuhlukahlukene ngoba ukushisela kungenziwa ngezindlela eziningi.

• Indololwane eyakhiwe:

Ngenxa yemikhawulo yesikhunta ngesikhathi sokubunjwa, ukwakheka nosayizi kungase kulinganiselwe.

5. Izindleko:

• Indololwane yokushisela:

Ngokuvamile ukonga kakhulu, ikakhulukazi efanelekayo amasistimu amapayipi amancane.

• Indololwane eyakhiwe:

Izindleko zokukhiqiza zingase zibe phezulu, kodwa kwezinye izimo ezikhethekile, ukusebenza kwayo nokuqina kungase kunciphise izindleko eziphakeme.

Sekukonke, ukukhetha phakathi kwezindololwane ezishiselwe noma ezifojiwe kuncike ezidingweni ezithile zohlelo, isabelomali, nezici zohlelo lwamapayipi.
