Sivame ukuthi ipayipi elinwetshiwe elishisayo libhekisela epayipini lensimbi elinobukhulu obuphansi kodwa elinciphayo, i-China National Standards Association ibeka ukuthi ipayipi lensimbi elinwetshiwe elishisayo kufanele libe ipayipi lensimbi elikhulu elinwetshiwe futhi eliguquliwe ngemva kokushisa okuphelele kwepayipi lensimbi elingenalutho. Ubuchwepheshe bokukhulisa ukushisa buwukwandisa ububanzi bepayipi ngokuguqulwa kwe-radial, okungukuthi, amamodeli akhethekile angewona ajwayelekile amapayipi angenamthungo angakhiqizwa kusetshenziswa amapayipi ajwayelekile, futhi izindleko ziphansi futhi ukusebenza kahle kokukhiqiza kuphezulu. Kuyindlela evamile yokucubungula amapayipi angenamthungo. Ngenxa yokuthuthukiswa kwepharamitha ephezulu yama-boilers esitshalo samandla kanye nokuthuthukiswa okukhulu kwezitshalo ze-petrochemical, isidingo samapayipi angenamthungo amakhulu nawo siyakhula, futhi kunzima ngamayunithi okugoqa amapayipi ukukhiqiza ipayipi elingenamthungo elinobubanzi obungaphezu kuka-508mm, isilinganiso sobubanzi bangaphandle nobukhulu bodonga (D/S)>25, ubuchwepheshe bokukhulisa ukushisa, ikakhulukazi ubuchwepheshe bokukhulisa ukushisa obuphakathi obungabizi kakhulu buye bathuthuka kancane kancane ngaleyo ndlela.
Isandisi sepayipi eliqhumayo esinezinyathelo ezimbili esisetshenziselwa amapayipi ensimbi anwetshiwe ngokushisa sihlanganisa ubuchwepheshe bokukhulisa ububanzi be-cone die, ubuchwepheshe bokushisa obuphakathi kwe-digital frequency induction, kanye nobuchwepheshe be-hydraulic emshinini owodwa. Ngenqubo yaso efanelekile, ukusetshenziswa kwamandla okuphansi, ukutshalwa kwezimali okuphansi kokwakha, kanye nokuhle. Ikhwalithi yomkhiqizo, ububanzi bezinto zokusetshenziswa kanye nokucaciswa komkhiqizo, ukuguquguquka kanye nokuzivumelanisa nezimo kweqembu lokukhiqiza okufakwayo okuphansi kuthathe indawo yobuchwepheshe bokukhulisa ububanzi bendabuko bokudonsa embonini yamapayipi ensimbi.
Kufanele kuqashelwe ukuthi izakhiwo zemishini zamapayipi ensimbi anwetshiwe ngokushisa ngokuvamile zimbi kancane kunamapayipi ensimbi aguqiwe ngokushisa.
Inqubo evamile yokwandisa ukushisa kwepayipi iwukulungisa ipayipi kusikulufu sokuhola, ubeke i-anvil ephezulu emise okwekhoni enobubanzi obukhulu kunobubanzi bepayipi kolunye uhlangothi lwepayipi, bese uxhumanisa bese ulungisa esinye isikulufu esisepayipini. Ukuxhumana phakathi kwepayipi ne-anvil ephezulu kungaphansi kwe-intermediate frequency heating coil, ukuze ulwe nokushisa ngokushesha okukhulu nokuqhuma, udinga ukudlulisa amanzi epayipini kuqala, uqale ukushisa kwe-coil, futhi ngemva kokufinyelela izinga lokushisa elibekiwe, isikulufu esixhumanisa ipayipi sisunduza ipayipi, ukuze ipayipi lihambe liye e-anvil ephezulu futhi linwebeke. I-anvil ephezulu i-taper yandisa ububanzi bepayipi. Ngemva kokuba lonke ipayipi lidlule, ipayipi ngeke liqonde ngenxa yenqubo yokwandisa ukushisa, ngakho-ke kudingeka liqondiswe.
Lokhu okungenhla okuqukethwe okuyisisekelo kobuchwepheshe bokukhulisa ukushisa.
Okulandelayo ifomula efanele yepayipi enwetshiwe yokushisa
Isisindo esinwetshiwe:
insimbi yekhabhoni: (ubukhulu obuyindilinga)× ukujiya× 0.02466 = isisindot yemitha eyodwa (kg)
ingxubevange: (ubukhulu bobubanzi)× ukujiya× 0.02483 = isisindoyemitha elilodwa (kg)
inani lamamitha ngemva kokwandiswa okushisayo：
Ububanzi bepayipi yokuqala÷ ububanzi obunwetshiwe obushisayo× 1.04× ubude *
amamitha epayipi okuqala：
ubude obunwetshiwe× (ububanzi÷ ububanzi beshubhu yokuqala÷ 1.04)
isivinini:
100000÷ (ubukhulu bobubanzi bokuqala× ukujiya)
ukujiya:
ukujiya okunwetshiwe (isikhathi esisodwa) ) = Ukujiya kwepayipi yokuqala× 0.92
Ubukhulu obunwetshiwe (izikhathi ezi-2) = Ubukhulu bepayipi yokuqala*0.84
Ububanzi:
Ububanzi obunwetshiwe = usayizi wesikhunta + ubukhulu obunwetshiwe× 2
Usayizi wesikhunta: ububanzi obunwetshiwe—2 * izindonga ezinwetshiwe Ubukhulu
Ukubekezelelana kobubanzi：
Ububanzi＜426mm, ukubekezelelana±2.5
Ububanzi426-630mm, ukubekezelelana±3
Ububanzi＞630mm, ukubekezelelana±5
Ukuphelela kwe-elliptic:
Ububanzi＜426mm, ukubekezelelana±2
Ububanzi＞426mm, ukubekezelelana±3
Ubukhulu:
ukujiya≤20mm, ukubekezelelana﹢2 ，—1.5
ukujiya≤40mm，﹢3 ，—2
Ipayipi lokwenza ukufakwa kwepayipi

Ngaphakathi nangaphandle kokuklwebheka:
Ukujula kokuklwebheka: 0.2mm, ubude: 2cm, kubizwa ngokuthi ukuklwebheka. Akuvunyelwe
Ukuqonda: ≤Imitha engu-6, ukugoba kungu-5mm，≤Imitha eyi-12, ukugoba kungu-8mm
Isibonelo:
Ishubhu yokuqala 610*19 enwetshiwe eshisayo 660*16
Ubude bepayipi yokuqala: 12.84meter
Ubukhulu obunwetshiwe: 19*0.92=17.48(isikhathi esingu-1)
19*0.84=15.96(I-1965)Izikhathi ezimbili）
Ubude obunwetshiwe bepayipi: 610÷660*1.04*12.84=12.341962
Ububanzi obunwetshiwe: 625+17.48*2+1=660.96(isikhathi esingu-1)
625+15.96*2+1=657.92(izikhathi ezi-2)
Usayizi weModule: 660-2 * 16 = 628
