Pipe welded spiral ho an'ny fantsona entona voajanahary
Spiral welded pipe, fantatra ihany koa amin'ny hoefantsonaweld, dia novokarina tamin'ny fampiasana teknolojia welding mandroso mba hamoronana vokatra matanjaka.Izy io dia misy tady miolikolika mitohy miforona avy amin'ny tady vy miolikolika miaraka.Ity rafitra tsy manam-paharoa ity dia manome hery tsy manam-paharoa, ka mahatonga azy ho tonga lafatra amin'ny fangatahana fangatahana toy nytsipika entona voajanahary.
Ny iray amin'ireo fampiharana lehibe amin'ny sodina welded spiral dia ny fitaterana entona voajanahary.Izy io dia natao manokana sy novolavolaina mba hahatohitra ny tontolo misy tosidra ambony mifandray amin'ny fifindran'ny entona voajanahary.Ny fantsona welded spiral dia miantoka ny fandefasana entona voajanahary azo antoka sy mahomby amin'ny indostria sy ny mpanjifa, miantoka ny famatsiana azo antoka ary manamaivana ny mety hisian'ny fivoahana na loza.

Ankoatry ny,sodina welded spiraldia ampiasaina betsaka amin'ny famatsian-drano sy ny rafitra drainage.Ny fananganana azy tsy mitete sy ny fanoherana ny harafesina no mahatonga azy io ho safidy tonga lafatra amin'ny fitaterana rano avy amin'ny loharano mankany amin'ny toerana haleha.Noho ny faharetany dia mahatanty ny fepetra henjana matetika mitranga amin'ny tetikasa famatsian-drano, manome vahaolana maharitra sy azo itokisana ny vondrom-piarahamonina sy ny indostria.
Ao amin'ny indostrian'ny petrochemical, ny sodina welded spiral dia mitana anjara toerana lehibe amin'ny fitaterana entona, etona, entona solika sy akora hafa.Ny tanjany avo sy ny fanoherana ny harafesina dia mahatonga azy ho safidy tsara indrindra amin'ny fampitana ireo akora mivaingana ireo.Na ozinina petrochemical lehibe izany na fametrahana kely, ny fantsona miolikolika dia miantoka ny fitaterana azo antoka sy mahomby amin'ireo loharano manan-danja ireo.
Ankoatra izany, ny firafitry ny spiral welded sodina dia be mpampiasa.Matetika izy io no ampiasaina ho fantsona ho an'ny fototra amin'ny tetikasa fanorenana, manome fanohanana sy fahamarinan-toerana ilaina.Ny hafetsen'ny fantsona koa dia mahatonga azy ho safidy voalohany ho an'ny tetezana, seranana, lalana ary trano fanorenana.Ny fahafahan'izy ireo manohitra ny enta-mavesatra sy ny hery ivelany dia miantoka ny fiarovana sy ny fahamendrehan'ireo rafitra ireo, ka mahatonga azy ireo ho singa tsy maintsy ilaina amin'ny sehatry ny fanorenana an-drenivohitra.
Ho fehin-kevitra, ny sodina welded spiral (fantatra ihany koa amin'ny hoe sodina sodina) dia manome vahaolana maro sy maharitra ho an'ny indostria sy sehatra isan-karazany.Ny isan-karazany ny fampiharana dia ahitana ny famatsiana rano injeniera, petrochemical orinasa, simika orinasa, herinaratra herinaratra orinasa, fambolena fanondrahana, tanàna fanorenana, sns Na ampiasaina amin'ny fitaterana ranon-javatra na entona, na ho an'ny tanjona ara-drafitra, spiral welded sodina dia azo antoka sy safidy mahomby.Miaraka amin'ny tanjany miavaka, ny elasticité ary ny fanoherana ny harafesina, dia mijanona ho singa manan-danja amin'ny indostria maoderina.
