Zeziphi iindlela zokwandisa i-diameter yangaphandle ye-20 # yombhobho wentsimbi wokuqhekeka kwe-oyile? Ziziphi iingenelo? Ngophuhliso lobuchwephesha boshishino kunye nepetroleum kunye namashishini ekhemikhali, imfuno yemibhobho yentsimbi engenamthungo enobubanzi obukhulu iye yanda unyaka nonyaka. Nangona iiyunithi ezinkulu zokuqengqeleka kombhobho webhayisikile kunye neeyunithi zokugqogqa kombhobho zinokuvelisa imibhobho yentsimbi enobubanzi obukhulu 20#, izixhobo zabo zikhulu, utyalo-mali lwexesha elinye luphezulu, kwaye kukho ubunzima obuthile bobugcisa ekuveliseni ubukhulu obukhulu bobubanzi obuncinci. imibhobho enezindonga. Kukho ikakhulu ezi ndlela zilandelayo zokwandiswa okushushu kwemibhobho:

(1) I-oblique rolling eshushu yokwandiswa kwe-20 # i-oyile yokuqhekeka ipayipi yentsimbi iqhutyelwa kumatshini wokwandisa oblique. Umatshini wokwandisa i-oblique rolling ine-conical rollers ezimbini ezifakwe kwi-box-shaped frame. Iimpawu zokwandiswa kwe-oblique rolling ye-20 # i-oyile yokuqhawula umbhobho wensimbi yi-deformation enkulu, isantya sokuguqulwa ngokukhawuleza, kunye nemveliso ephezulu. Ifanelekile ukuvelisa i-diameter enkulu kunye ne-medium-thin-wall 20 # i-oyile yokuqhawula imibhobho yentsimbi yamanqanaba ahlukeneyo entsimbi kunye nokuchaneka okuphezulu, kodwa ukungabikho kwayo kukuba izixhobo zeyunithi zikhulu, utyalo-mali luphezulu, kwaye alukwazi ukuvelisa ezizodwa. imibhobho engenamthungo emile kwaye eguquguqukayo.

(2) Ukwandiswa okushushu kwe-20 # i-petroleum yokuqhekeka umbhobho wentsimbi kuqhutyelwa kumatshini wokwandisa umzobo oshushu. Iimpawu zezokuba umatshini wokwandisa unokutshisa kokubili ukwandisa kunye nokutsala okushushu, kwaye awukwazi nje ukutshisa ukwandisa imibhobho ejikelezayo, kodwa kwakhona ukutsala imibhobho ekhethekileyo kunye necandelo eliguquguqukayo; izixhobo zomzobo kunye nokwandisa umatshini kukhanya, utyalo-mali luncinci, kwaye ukutshintshwa kwesixhobo kulula; kodwa ngenxa yokuba umzobo kunye nokwandisa ukuguqulwa kwamahhala, iziphene zomphezulu we-20 # wepetroleum wokuqhekeka umbhobho wentsimbi yeemveliso ezongeziweyo kulula ukuveza nokwandisa, kunye nokuchaneka kodonga kunye nokuchaneka kwedayamitha yangaphandle ayiphezulu.

(3) Kwiminyaka yakutshanje, kuye kwavela inkqubo entsha yokwandisa i-medium-frequency induction hydraulic-two-step-step-type anti-inflammatory, eyahluke kumzobo wendabuko kunye nenkqubo yokwandisa. Isetyenziselwa ukuvelisa i-diameter enkulu ye-20 # yepetroleum yentsimbi yokuqhekeka imibhobho. Izixhobo zenkqubo zilula, kwaye iyunithi nganye inamashumi eetoni. Ngaphezu koko, imibhobho yentsimbi yokuqhekeka yepetroliyamu eyandisiweyo engama-20# ilingana ubukhulu becala, inamakhozo acolekileyo kunye neempawu ezilungileyo zoomatshini. Ngoko ke, iye yaba yeyona idumileyo enkulu-ebubanzini 20 # petroleum yokuqhekeka inkqubo yokuvelisa umbhobho wentsimbi.
