Paunotanga kutsvaga pombi yesimbi, ingave yefekitari yekubvisa munyu, yeoiri, kana gwenya remagetsi enyukireya, mubvunzo wekutanga waunofanira kuzvibvunza ndewekuti “ndinoda “pombi” dzisina musono, dzakasungwa, kana kuti dzakafodherwa here? Aya matatu Rudzi rumwe norumwe rune mabhenefiti akasiyana uye saka akakodzera kune akasiyana maapplication uye nharaunda. Pane zvinhu zvakati kuti zvinofanirwa kutariswa pakusarudza izvo zvakafanira kune imwe chirongwa.

Mainjiniya vangangoziva mhinduro kumubvunzo uyu intuitively, asi ngatitorei chinguva tiongorore iyi pombi isina musono, pombi yakakandwa uye pombi dzefogi nezvinhu zvadzo zvakasiyana.

1. Pombi isina musono

Ngatitangei isina musono pombi. Sezvinoratidzwa nezita racho, pombi isina musono ipombi isina musono kana mawelds.

Kugadzira uye Kushandisa:

Seamless tubing inogona kugadzirwa uchishandisa nzira dzakasiyana siyana, zvakanyanya zvichienderana nedhayamita inodiwa, kana chiyero chedhayamita kusvika kumadziro ukobvu. Kazhinji kutaura, iyo isina musono pombi yekugadzira nzira inotanga nekukanda simbi mbishi mune imwe fomu inoshanda - inopisa yakasimba billet. Zvadaro woitambanudza uye woisundira kana kuidhonza pamusoro pefomu. Iyi hollow chubhu inozoenda kuburikidza neextrusion process apo inomanikidzwa kuburikidza nefa uye mandrel. Izvi zvinobatsira kuwedzera dhayamita yemukati uye kuderedza dhayamita yekunze.

Seamless simbi pombi inowanzoshandiswa kutakura zvinwiwa zvakaita semvura, gasi rechisikigo, tsvina uye mweya. Inowanzodiwawo munzvimbo dzakawanda dzakanyanya kudzvinyirira, nzvimbo dzinoparadza zvakanyanya semafuta negesi, kugadzira magetsi uye maindasitiri emishonga.

Advantage:

Simba repamusoro: Pombi isina musono ine mukana wakajeka wekuti hapana seams, saka hapazove neane simba seams. Izvi zvinoreva kuti kazhinji, pombi isina musono inogona kumira 20% yakakwirira kushanda kumanikidza pane yakashongedzwa pombi yegiredhi rezvinhu zvakafanana uye saizi.
High Resistance: Kusavapo kwemaseams kunoreva kuti mapaipi asina musono anogona kupa yakakwira corrosion resistance, sezvo matambudziko akadai setsvina uye hurema hunowanzo itika pamawelds.

Kuedza kushoma: Hazvina basa kutaura, isina musono tubing haidi kuongororwa kuvimbika kwe weld - hapana weld zvinoreva kuti hapana bvunzo!

2. Welded pipe

Kune marudzi matatu emapombi akaiswa: ekunze dhayamita welding, mukati dhayamita welding kana kaviri-sided welding. The common denominator ndeyekuti vese vane seams!

Nzira yekugadzira pombi yakasungwa inotanga nekukungurutsa coil yesimbi kusvika pahukobvu hunodiwa kuti iite tambo yakatsetseka kana ndiro. Inobva yapetwa uye mitsetse yechubhu inoguma inosungirirwa munzvimbo ine makemikari asina kwayakarerekera.

Nezve kuti ndedzipi mhando dzesimbi dzinogoneka, austenitic simbi dzinowanzove dzakanyanya kuputika, nepo ferritic simbi inopinza zvikamu zvitete. Duplex simbi zvino zvave kutariswa zvakazara weldable, asi zvinoda kutariswa zvakanyanya kupfuura austenitic simbi.

Welded pombi yekugadzira tekinoroji inoonekwa seyakagadziridzwa zvakanyanya mumakore mashoma apfuura. Zviri pachena kuti chakanyanya kukosha kufambira mberi kwaive kuvandudzwa kwehunyanzvi hwekugadzira welding uchishandisa high-frequency currents. Izvi zvinonatsiridza zvikuru kugona kwepombi yakasungwa kudzivirira ngura uye kutadza kwemajoini.

Nepo seams mune welded pombi ari echokwadi kuti aite kushaya simba, nzira dzekugadzira uye maitiro ekusimbisa hunhu akakwira zvakanyanya nhasi. Izvi zvinoreva kuti chero bedzi iyo yakataurwa tembiricha uye kushivirira kushivirira kwepombi yakashongedzwa isati yapfuudzwa, hapana chikonzero nei isingaite pamwe nemusono pombi mumaindasitiri akawanda.

Mutengo: Imwe yemabhenefiti makuru e welded pombi ndeyekuti ndiyo yakachipa yemhando dzese dzepombi uye inowanikwa zviri nyore.
Consistency: Zvinowanzogamuchirwa kuti welded pombi inopindirana muukobvu hwemadziro kupfuura pombi isina musono. Izvi zvinodaro nekuti nzira yekugadzira inotanga nepepa rimwechete resimbi.
Surface Hunhu: Kudzivirira iyo extrusion maitiro zvakare zvinoreva kuti pamusoro pemapombi akasungwa anogona zvakare kutsetseka kupfuura mapaipi asina musono.
Kumhanyisa: Welded pombi inoda kupfupika kwekutenga kutungamira nguva nekuda kwekureruka kwekugadzira maitiro.

3. Mutopota wakabirwa

Steel forging isimbi yekugadzira nzira inoshandisa kudzvanyirira masimba uye kupisa kwakanyanya uye kumanikidza kuumba simbi.

Kugadzirwa kwepombi dzakagadzirwa kunotanga nekuisa chidimbu chesimbi (ingave 6% molybdenum, super duplex, duplex, simbi isina tsvina, nickel alloy) pakati pepamusoro nepasi inofa. Simbi inoumbwa nekupisa uye kudzvanywa muchimiro chaidiwa uyezve inopedzwa nemaitiro ekugadzira kuti asangane nezvose zvinodiwa.

Iyi yakaoma nzira yekugadzira inoguma nekuwedzera mutengo wefoged chubhu.

Iwo akawanda mabhenefiti efoged chubhu zvinoreva kuti ine akawanda akasiyana mashandisirwo munzvimbo dzakasiyana senge oiri negesi, hydraulic muchina, fetiraiza uye indasitiri yemakemikari. Iyo chokwadi chekuti simbi yekunyepedzera haina ma seams kana welds inobvumira kuti ibudirire kuva nezvinhu zvinokuvadza kana zvinopisa uye utsi hwazvo. Naizvozvo, inogona kushandiswa mumaindasitiri mazhinji anorema.

High Strength: Mapombi akafodhiwa anowanzo gadzira chakasimba uye chakavimbika chekupedzisira chigadzirwa nekuti kugadzira kunoita kuti tsanga dzesimbi ichinje nekuenderana. Mune mamwe mazwi, simbi yakave yakanyatsonaka uye chimiro chepombi chakachinja zvakanyanya, zvichikonzera kusimba kwakasimba uye kupikisa kwakanyanya.
Hupenyu Hurefu: Kugadzira kunobvisa zvingangoita porosity, shrinkage, cavities uye kutonhora kudira nyaya.
Economical: Maitiro ekugadzira anowanzoonekwa seane hupfumi zvakanyanya sezvo pasina zvinhu zvinoraswa.
Flexibility: Iyo simbi yekuumba maitiro inochinjika uye inogona kugadzira machubhu muhukuru hwakasiyana.
