Umbhobho odityanisiweyo weSpiral (isasa): Yenziwa ngokuqengqeleka intsimbi ephantsi-carbon carbon structural okanye ephantsi ingxubevange yesakhiwo steel strip ibe ityhubhu blank ngokwe-engile helical ethile (ebizwa engile yokubumba), kwaye ke welding umthungo umbhobho. Ingenziwa ngentsimbi emxinwa yomcu ivelisa imibhobho yentsimbi enkulu enobubanzi. Iinkcukacha zayo zibonakaliswa ngedayamitha yangaphandle * ubukhulu bodonga. Iumbhobho odityanisiweyokufuneka kuqinisekiswe ukuba uvavanyo lwe-hydraulic, ukuqina kokuqina kwe-weld kunye nokusebenza okugoba okubandayo kufuneka kuhlangabezane nemimiselo.

Izinto eziluncedo kwi-spiral welded pipe:

(1) Imibhobho yentsimbi enobubanzi obuhlukeneyo inokuveliswa ngokusebenzisa intsimbi yomtya yobubanzi obufanayo, ingakumbi imibhobho yentsimbi enobubanzi obukhulu inokuveliswa ngentsimbi emxinwa.
(2) Phantsi kweemeko ezifanayo zoxinzelelo, uxinzelelo lwe-spiral welded seam luncinci kunolo lomthungo othe tye, ongama-75% ukuya kuma-90% wombhobho odityanisiweyo othe ngqo, ngoko unokumelana noxinzelelo olukhulu. Xa kuthelekiswa nemibhobho edityanisiweyo ethe tye enobubanzi obufanayo bangaphandle, ubukhulu bodonga bungancitshiswa nge-10% ukuya kwi-25% phantsi koxinzelelo olufanayo.
(3) Imilinganiselo, ukunyamezela kwe-diameter ngokubanzi akudluli i-0.12%, ukuphambuka kungaphantsi kwe-1/2000, kwaye i-ellipticity ingaphantsi kwe-1%. Ngokuqhelekileyo, iinkqubo zokulinganisa kunye nokulungelelanisa zingashiywa.
(4) Inokuveliswa ngokuqhubekayo. Kwithiyori, inokuvelisa imibhobho yentsimbi engapheliyo. Ukulahlekelwa kwentloko kunye nomsila kuncinci, kwaye izinga lokusetyenziswa kwesinyithi linganyuswa nge-6% ukuya kwi-8%.
(5) Xa kuthelekiswa nombhobho we-weld we-longitudinal, iguquguqukayo ekusebenzeni kwaye ilungele ekutshintsheni iintlobo kunye nohlengahlengiso.
(6) Isixhobo sinobunzima obuncinci kwaye siphantsi kutyalo-mali lokuqala. Ingenziwa ibe yiyunithi ephathwayo yohlobo lwetreyila ukuvelisa imibhobho edityanisiweyo ngokuthe ngqo kwindawo yokwakha apho imibhobho ibekwe khona.
(7) Kulula ukuqonda umatshini kunye ne-automation.

Ububi bombhobho we-spiral welded yile:ngenxa yokuba intsimbi ephothiweyo yentsimbi isetyenziswa njengento ekrwada, kukho ukugoba okuthile, kwaye indawo yokuwelda ikwindawo emphethweni wentsimbi ene-elasticity, ngoko akukho lula ukulungelelanisa itotshi yokuwelda, echaphazela ukuwelda. umgangatho. Ukwenza oku, ukulandelwa komthungo onzima kunye nezixhobo zokuhlola umgangatho zisekiwe.

Isalathiso sophuhliso lombhobho we-spiral welded:

Ngenxa yokunyuka koxinzelelo oluphezulu lombhobho, iimeko zenkonzo ezirhabaxa ezisandayo, kunye nesidingo sokwandisa ubomi benkonzo yombhobho kangangoko, elona cala liphambili lophuhliso lombhobho odityanisiweyo ngulo:
(1) Ukuvelisa imibhobho etyebileyo enobubanzi obukhulu obunodonga ukuze kuphuculwe ukumelana noxinzelelo;
(2) Yila kwaye uvelise imibhobho yentsimbi enezakhiwo ezitsha, njengemibhobho edityanisiweyo ephindwe kabini, oko kukuthi, imibhobho edityanisiweyo yomaleko kabini enesiqingatha sobungqingqwa bodonga lombhobho, ongenamandla angaphezulu kuphela kunomaleko omnye. imibhobho yobukhulu obufanayo, kodwa kwakhona ayibonakali ingaphumeleli brittle;
3

(4) Ukuphuhlisa ngamandla imibhobho egqunyiweyo, njengokugquma udonga lwangaphakathi lombhobho kunye ne-anti-corrosion layer, engenako ukwandisa ubomi benkonzo kuphela, kodwa iphucula ukugudiseka kodonga lwangaphakathi, ukunciphisa ukuxhathisa ulwelo, ukunciphisa i-wax. ukuqokelela kunye nokungcola, ukunciphisa inani lemibhobho yokucoca, kunye nokunciphisa iindleko zokugcina.

PS:Imibhobho yentsimbi edityanisiweyobabe neendleko eziphantsi kunye nokusebenza kakuhle kwemveliso kunoiityhubhu ezingenamthungo. Umbhobho odityanisiweyo othe ngqo unenkqubo elula yokuvelisa, ukusebenza kakuhle kwemveliso, ixabiso eliphantsi kunye nophuhliso olukhawulezayo. Amandla ombhobho we-spiral welded ngokubanzi uphezulu kunombhobho odityanisiweyo othe tye.
