Stainless steel welded pipe yivula phayiphi ya nsimbi leyingana strict internal na external dimensional accuracy (tolerance range), ku hetiseka lokunene ka le ndzeni nale handle ka le handle, ku rhendzeleka, ku kongoma, na ku tiya ka rirhangu leri fanaka. Swikombiso leswikulu swa xithekiniki swa phayiphi leyi weldiweke ya nsimbi leyi nga riki na swilo leswi nga riki na swilo leswi humesiweke hi thekinoloji leyi swi fikile kumbe swi tlula hi xiphemu mpimanyeto wa rixaka wa GB12777-2002 na swilaveko swa ISO4394/I-1980 (E). Ndlela yo lawula ku pakanisa ka stainless steel welded pipe i mhaka ya nkoka.
Hikwalaho ka density yale henhla swinene ya tiphayiphi ta stainless steel welded, hambi loko xivumbeko xale handle xinga pholishiwanga, hi xitalo xinga fika kwalomu ka 260 mesh. Loko phayiphi ya welded ya nsimbi leyi nga riki na swilo yi pholishiwile endzeni na le handle, ku kongoma ka yona ku ta hunguteka. Hikwalaho, loko ku ri ni swilaveko swo hlawuleka swa ku lulama ka phayiphi ya nsimbi, hi ntolovelo ku pholisha a swi bumabumeriwi. Vuandlalo lebyi pholishiweke bya phayiphi leyi weldiweke ya nsimbi leyi nga riki na swilo se byi hatima swinene. Phayipi ya kahle ya welded welded welded welded welded welded performance performance ya kahle swinene, yinga tiyisela ntshikelelo wale henhla, yivumbiwile hi xirhami, yi flared, naswona yi phaphatiwile handle ko pandzeka kumbe ku rhurhumela. Yi nga endla ti deformations to hambana hambana leti rharhanganeke na ku lulamisiwa ka michini. Endzhaku ka loko phayiphi leyi weldiweke ya nsimbi leyi nga riki na swilo yi annealed vacuum, phayiphi ya nsimbi yi nga ha endliwa.
Tiphayiphi leti weldiweke ta nsimbi leyi nga riki na swilo hi ntolovelo ti tirhisiwa ku endla swivumbeko swa michini, switirhisiwa swa hayidiroliki, michini na tindhawu tin’wana ta vuhumelerisi. Eka swiyenge swa switirhisiwa, switirhisiwa swa vutshunguri, switirhisiwa swa vukheta, switirhisiwa swa elektroniki, swihahampfhuka, tiphayiphi ta mphakelo wa mati yo tontswa na swicincana swo hisa, tiphayiphi leti weldiweke leti tirhisiwaka ti laveka ku va na ku pakanisa ka dimensional ya le henhla ya diameter. Swigayo swa tiphayiphi leswi tolovelekeke leswi weldiweke a swi nge swi koti ku fikelela xilaveko lexi. Seko Machinery yi ku yisa ku xopaxopa ndlela leyi switirhisiwa swa tiphayiphi leswi weldiweke na swilo swa vuhumelerisi swi khumbaka ku pakanisa ka dimensional ka stainless steel stainless welded pipe outer diameter.
1. The dimensional accuracy requirements of high-precision stainless steel welded pipes
From GB/T 3639-2000 'Cold-drawn or cold-rolled precision seamless steel pipes' and ASTM A1016, GB/T 12770-2002 'Stainless steel welded pipes for mechanical structures' and other standards, it can be seen that the relevant standards have an impact on Precision Tiphayiphi ta nsimbi leyi nga riki na swilo leswi weldiweke. Ku hambuka loku pfumeleriwaka ka dyayimeta (Tafula 1) na ku hambuka ka ku tiya ka rirhangu (Table 2) swilaveko. Ku tiyisela ka inner diameter ya welded pipe swi khumbeka ngopfu hiku tiyisela ka outer diameter xikan’we naku tiyisela ku enta ka rirhangu. Xihloko lexi a xi vulavuli hi mhaka ya ku tiyisela ka inner diameter.
2. Analysis of factors affecting the dimensional accuracy of the outer diameter of stainless steel welded pipes
2.1 The influence of steel strip thickness and width accuracy
2.2 The outside diameter tolerance of welded pipe before sizing and the influence of sizing amount
1) Dimension tolerance of welded pipe outside diameter before sizing
The outer diameter tolerance of the welded pipe before sizing is affected by the superposition of many factors such as the tolerance of the steel Strip, ku pakanisa ka dimensional ka welding roll na gap ya yona.
.
Nsinya wa nawu wa ku kumisisa nhlayo ya vukulu i: 1 nhlayo ya vukulu yifanele kuva yikulu kutlula ku tiyisela ka diameter yale handle ya phayiphi leyi weldiweke emahlweni ka diameter; 2 Nhlayo ya vukulu lebyi eneleke na minkarhi yo hundza.
2.3 Ku tiya ka furemu ya muchini wo pima mpimo na nkucetelo wa vukulu bya switirhisiwa .
2.3.1 Ku tiya ka furemu
Ku onhaka ka ku olova ka le hansi ka muchini wo pima tiphayiphi leti weldiweke swi ringana na nhlayo ya ku onhaka ka ku olova ka nxaxamelo wa swiphemu leswi tshikilelekeke eka xisekelo.
2.3.2 Matimba yo rhendzeleka ya vukulu .
1) Ntshikelelo wa yuniti ya le xikarhi
2) Ndhawu ya vuhlanganisi
3) Ku pima matimba yo rhendzeleka .
2.3.3 Elastic deformation ya xisekelo xa muchini wa vukulu .
2.4 Nkucetelo wa ku pima ku pima switirhisiwa swa vumaki Ku pakanisa ka
vumaki Ku pakanisa ka vumaki bya muchini wo pima swi khumba hi ku kongoma ku tiyisela ka diameter ya le handle ka phayiphi leyi weldiweke .
Ku lulama ka vukulu na ku anama ka steel strip swi khumba ntsena ku pakanisa ka diameter yale handle ya phayiphi leyi weldiweke loko kungase endliwa sizing, kambe kungari ngopfu hi nkarhi wa maendlelo ya sizing. Sizing pass xikan’we na sizing amount swikumiwa ngopfu kuya hi outer diameter tolerance ya welded pipe loko kungase endliwa sizing. Nhlayo leyi ringaneleke ya sizing pass na sizing i xitiyisekiso xa xisekelo xo antswisa ku pakanisa ka diameter yale handle ya xitirhisiwa lexi hetiweke xa welded pipe. Swilo leswikulu leswi khumbaka ku pakanisa ka dyayimeta ya le handle ya phayiphi leyi weldiweke i vukulu bya muchini wo pima mpimo ni ku pakanisa ka vumaki bya switirhisiwa. Hangao Tech (Michini ya Seko) . Precision High-Speed Stainless Steel Industrial Pipe Machine , Model na Mold Design swi lawuriwa kahle, naswona nxaxamelo wa maendlelo ku katsa na ku vumba welding, annealing bright, precise sizing, na swin’wana swi nga hetiwa eka inthanete, leswi nga fikelelaka vuhumelerisi lebyi yaka emahlweni bya tiawara ta 24. Ku kuma vuxokoxoko byo tala, hi kombela u vulavurisana!
