Imibhobho yentsimbi ene-Spiral isetyenziswa ikakhulu njengemibhobho yolwelo kunye nemibhobho yokufumba. Ukuba umbhobho wentsimbi usetyenziselwa ukukhupha amanzi, ngokuqhelekileyo uya kufumana unyango oluchasene ne-corrosion kwindawo yangaphakathi okanye yangaphandle. Unyango oluqhelekileyo lwe-anti-corrosion lubandakanya i-3pe anti-corrosion, i-epoxy coal tar anti-corrosion, kunye ne-epoxy powder anti-corrosion. Lindela, ngenxa yokuba inkqubo ye-epoxy powder dipping ikhathazwa ziingxaki zokubambelela, inkqubo ye-epoxy powder dipping ayizange iphakanyiswe. Ngoku, ngophuhliso oluyimpumelelo lwesisombululo esikhethekileyo sephosphating ye-epoxy powder dipping, ingxaki yokuncamathela yenkqubo yokudipha i-epoxy powder iye yoyiswa okokuqala, kwaye inkqubo evelayo ye-epoxy powder dipping iqalile ukubonakala.

Ukuhlalutya oonobangela bokungalingani kokutyatyekwa kobunzima bemibhobho yentsimbi ejikelezayo, ubukhulu obungalinganiyo bemibhobho yentsimbi ye-3PE ejiyileyo bubonakaliswa ikakhulu kubunzima obungalinganiyo bamanqaku ovavanyo kwicala ngalinye elisasazwe kwicala elijikelezayo. Umgangatho woshishino we-SY/T0413-2002 awunayo imigaqo yokulingana kobunzima. Ichaza ixabiso lobuninzi bengubo kodwa lifuna ukuba ixabiso lobuninzi bengubo ayinakuba ngaphantsi kwexabiso lobunzima benqaku, kunokuba ixabiso eliqhelekileyo lamanqaku okuvavanya amaninzi.

Ukuba ubuninzi bokugquma abulingani ngexesha lenkqubo yokugquma imibhobho yentsimbi ejikelezayo, izinto zokwaleka ngokuqinisekileyo ziya kuchithwa. Oku kungenxa yokuba xa ubukhulu bengubo kwi-thinnest part bufikelela kwinkcazo, ubukhulu bendawo eshinyeneyo buya kuba bukhulu kunobukhulu benkcazo ye-Coating. Ngaphezu koko, ukugquma okungalinganiyo kunokubangela ukuba ubukhulu becala lelona candelo lincinci lombhobho wentsimbi lusilele ukuhlangabezana nemigaqo. Izizathu eziphambili zobunzima obungalinganiyo ngexesha lenkqubo yokuvelisa izinto ezingalinganiyo zokuhambisa kunye nokugoba kombhobho wensimbi. Indlela esebenzayo yokulawula i-coat engalinganiyo ye-3PE ye-anti-corrosion pipes kukulungelelanisa i-extrusion dies ezininzi ukwenza i-anti-corrosion coating thickening kwiindawo ezininzi ngendlela efanayo kunye nokuthintela imibhobho yentsimbi engafanelekanga ukuba ifakwe kwi-intanethi.

Imibimbi ebusweni bokugquma: Ukukhutshwa kunye nokuvuthwa kwezinto ze-polyethylene kumbhobho wensimbi kufuna ukusetyenziswa kwe-silicone roller. Ukulungelelaniswa okungafanelekanga ngexesha le nkqubo kunokubangela imibimbi kumphezulu wengubo. Ukongezelela, ukuchithwa kwefilimu enyibilikayo xa i-polyethylene ishiya i-exit die ngexesha lenkqubo ye-extrusion iya kuvelisa iziphene ezisemgangathweni ezifana nemibimbi. Iindlela zokulawula ezihambelanayo zezizathu zemibimbi ziquka ukulungelelanisa ubunzima kunye noxinzelelo lwe-rubber roller kunye ne-pressure roller. Ukusuka kulo mbono, ngokufanelekileyo ukwandisa inani le-extrusion ye-polyethylene ukulawula ukugqabhuka kwefilimu enyibilikayo.
