Ukusebenza kunye nemisebenzi yombala wokuqala wentsimbi yomthungo umbhobho wentsimbi kwinkqubo ethile yokusetyenziswa kubonisa ngokupheleleyo igalelo lokusebenza kunye nokusetyenziswa. Emva kokupeyinta kunye nokutshiza iileta ezimhlophe, umbhobho wentsimbi othe tye ukhangeleka unamandla kwaye umhle. Ngoku izifakelo zePipe, nokuba ziyi-carbon steel straight seam seam pipes, iintloko ze-carbon steel okanye i-carbon steel tees, iminqamlezo, kunye nezinye izifakelo zemibhobho edityanisiweyo, zonke zikwimbala yazo yoqobo, zigcina iinkqubo. Nokuba ipeyintiwe, ibonakala ilungile kuphela ngelo xesha kwaye isebenzela injongo yokuthintela umphezulu ukuba ungagqwala. Emva kokuba umbhobho wentsimbi yomthungo othe tye udityaniswe kumbhobho, usafuna ukupeyintwa ukuthintela ukubola. Emva koko qhubela phambili kwinkqubo yokugcina ubushushu.

Ukusebenza kunye nemisebenzi yemibhobho yentsimbi yomthungo ochanekileyo kunye nombala wokuqala wemibhobho yentsimbi yomthungo kwinkqubo ethile yokusetyenziswa ibonisa ngokupheleleyo igalelo labo lokusebenza kunye nokusebenza kwazo. Emva kokupeyinta, kwatshizwa ngoonobumba abamhlophe, kwaye imibhobho yentsimbi yomthungo ethe tye nayo yabonakala inamandla kwaye intle, yongeza inkangeleko entle kakhulu. Kutheni kunje? Kukho izizathu ezibini. Kuvela ukuba umbhobho wensimbi othe tye ugcina umbala wawo wokuqala, kwaye unokubona indawo yokuqala ngaphandle kokuphazamiseka. Ixesha lokwakhiwa kwemibhobho yentsimbi yomthungo ethe tye inokuqhubela phambili, kwaye inokulayishwa kwaye ithunyelwe ngokukhawuleza xa ziveliswa. Yingcamango yam nje le.

Uthini umbala wokuqala wentsimbi yomthungo othe tye? Isebenzisa imibhobho yentsimbi yekhabhoni ukuvelisa imibhobho yentsimbi yomthungo ekhoyo ngoku, imibhobho yentsimbi yomthungo eyi-90-degree ethe tye, imibhobho yentsimbi yomthungo engama-45-degree, iintloko, i-Hebei elbow tees, kunye nezinye izixhobo ezidityanisiweyo zemibhobho ngaphandle kokupeyintwa kunye nokuchasana nokubola. umbala wokuqala. Lo mbala uquka obomvu (le yindlela eveliswa ngayo imibhobho yentsimbi yomthungo ngexesha lokuvelisa), kunye ne-cyan, engumbala wokuqala wemibhobho yetsimbi ethe tye. Imibhobho yentsimbi yokuqala yomthungo ethe tye yaveliswa kwaye ayinakuthengiswa ngaphandle kwepeyinti echasene nomhlwa. Uninzi lwazo ziimveliso ezigqityiweyo. Iphantse yaba ngumthetho weshishini. Ngaphandle koko, ayithathwa njengombhobho opheleleyo wentsimbi yomthungo othe tye. Ngexesha lokwakhiwa ebusika, imibhobho ayinakuchaphazeleka kakhulu kwimpembelelo kunye nokuphuka, okwandisa ukuguquguquka kwamalungiselelo okwakha. Ayinabungozi kokusingqongileyo kwaye inokuphinda isetyenziswe ngaphandle kokungcolisa okusingqongileyo. Ukungaphumeleli ukurisayikilisha kuya kubangela ungcoliseko lwesibini; kukho iingxaki ezifana nokulawula i-degree-linking degree kunye ne-cross-linking uniformity, kwaye ukucubungula kuyinkimbinkimbi kwaye kuchaphazela ngokuthe ngqo ukusebenza kombhobho.

Amanqaku amabini akufundisa indlela yokwahlula imibhobho yentsimbi yomthungo othe tye:
Imibhobho yentsimbi yomthungo ethe tye iyahlukaniswa ngokweedayimitha zayo zangaphandle: ezo zinedayamitha zangaphandle phakathi kwe-φ4.76 kunye ne-φ12.70 mm ziyimibhobho yentsimbi yomthungo we-fine-diameter straight-seam; ezo zinedayamitha zangaphandle phakathi kwe-φ13-φ114 mm ziyimibhobho yentsimbi yomthungo omncinci-ububanzi obuncinci; ezo zinedayamitha zangaphandle phakathi Ezo zinedayamitha yangaphandle phakathi kwe-φ114 kunye ne-φ406 mm ziyimibhobho yentsimbi eqhekekileyo ephakathi; ezo zinedayamitha yangaphandle engaphezulu kwe-φ406 mm ziyimibhobho yentsimbi enqamlekileyo yobubanzi obukhulu.

Ukwahlula imibhobho edityanisiweyo ngokobukhulu bodonga:
Ngokomlinganiselo wobunzima bodonga t ukuya kumbhobho wentsimbi wangaphandle D, imibhobho edityanisiweyo inokwahlulwa ibe zezi ndidi zintlanu zilandelayo: ① leyo ine-t/D ngaphantsi kwe-2% yimibhobho eyongezelelweyo enodonga olubhityileyo; ② abo bane-t/D elingana ne-2-5% yimibhobho enodonga olucekethekileyo; ③t/D Abo bane-/D enkulu kuno-5-12% yimibhobho yoqobo yoqobo eludongeni; ④ abo bane-t/D enkulu kune-12-18% yimibhobho enodonga olungqingqwa; 5) abo bane-t / D enkulu kune-18% yimibhobho ekhethekileyo yodonga olukhethekileyo.

Iityhubhu ezinodonga olucekethekileyo, iityhubhu ezinodonga oluqhelekileyo, kunye neetyhubhu ezinodonga olungqingqwa azohlulwa ngokwengqiqo ngexabiso lobunzima bodonga. Nangona kunjalo, eminye imigangatho inobunzima obuthathu bodonga olwahlukeneyo oluhambelana nobubanzi obungaphandle obufanayo. Imibhobho enobu bunzima bodonga zintathu inokubizwa ngokuba yimibhobho enodonga olucekethekileyo, imibhobho edityanisiweyo eqhelekileyo, kunye nemibhobho yentsimbi yomthungo engqindililiyo kumgangatho.

Ngenxa yokumelana nomhlwa, ukuxhathisa kwe-oxidation, i-anti-static, kunye neminye imisebenzi ekhethekileyo yemibhobho edityanisiweyo ethe tye, kunye nenkangeleko entle kunye nokuqina kwemibhobho edityanisiweyo ethe tye, iye ngokuthe ngcembe yaba ngumkhwa wokuzisebenzisa ukwenza oomatshini abathile. , amacandelo, kunye nemithombo. Njengoko inkqubo yetekhnoloji iqhubeka ikhula kwaye izinzile, imveliso ye "Xiangyang" yemveliso yomthungo we-weld welding ethe gqolo ikhula kwaye ikhula kwiminyaka yakutshanje, ingena ngokuthe ngcembe kwiinkalo ezahlukeneyo ezifana ne-hardware esebenzayo kunye neshishini lokwakha kunye nelokuhombisa kunye nelodwa. ukusebenza kunye nokusebenza kwepolynomial. Kwaye njengoko abantu beqhelana nayo, imfuno yayo iya kunyuka ngokukhawuleza, kwaye imimandla yokusetyenziswa kwayo iya kuba banzi kwaye ibe banzi. Omnye umzekelo yimibhobho ye-welding esetyenziswa ngokubanzi kunye nenani elikhulu lamacandelo ensimbi engenasici, izihlanganisi, njl., Iintsimi zazo eziye zahlala ngokubanzi ngemibhobho edibeneyo edibeneyo. Ukongeza, ngophuhliso lomgca ogcweleyo kunye nokusetyenziswa okunengqiqo kweemveliso zobuchwepheshe obuphezulu, umda wesicelo semibhobho edityanisiweyo ethe tye nayo iyanda. Amashishini amaninzi afuna imathiriyeli emitsha amkele imibhobho edityanisiweyo ethe tye. Ezona zicacileyo lishishini lemichiza kunye neshishini lefayibha yeekhemikhali. Ukuguqulwa kwezixhobo zemizi-mveliso.
