Payipu eya welded ekoleddwa mu kyuma ekitali kizimbulukuse kitegeeza payipu y’ekyuma erimu obutuufu obw’amaanyi obw’omunda n’obw’ebweru (okugumira ebanga), okumaliriza okw’okungulu okw’omunda n’okw’ebweru okulungi, okwetooloovu, okugolola, n’obuwanvu bw’ekisenge ekimu. Ebikulu ebiraga eby’ekikugu eby’ekyuma ekitali kizimbulukuse welded payipu ekolebwa tekinologiya ono bituuse oba ekitundu kyasukka ku mutindo gw’eggwanga GB12771-2002 ne standard ISO4394/I-1980 (E). Engeri y’okufuga obutuufu bwa payipu eya welded steel welded nsonga nkulu.
Olw’obunene bw’okungulu obw’ekyuma ekitali kizimbulukuse waggulu ennyo, ne bwe kiba nti ekitundu eky’ebweru tekisiigiddwa, okutwalira awamu kisobola okutuuka ku 260 mesh. Singa payipu ya welded ekoleddwa mu kyuma ekitali kizimbulukuse esiigibwa munda n’ebweru, obugolokofu bwayo bujja kukendeera. N’olwekyo, bwe wabaawo ebyetaago eby’enjawulo ku bugolokofu bwa payipu y’ekyuma, okusiimuula okutwalira awamu tekiba kirungi. Oludda olulungi olwa payipu ekoleddwa mu kyuma ekitali kizimbulukuse lwayaka dda nnyo. Payipu eno eriko ekyuma ekitali kizimbulukuse ekizingiddwa mu nnyonta erina omutindo omulungi ennyo, esobola okugumira puleesa ey’amaanyi, ekoleddwa mu nnyonta, efuukuuse, era efuukuuse nga teyatika wadde okunyiganyiga. Kisobola okukola okukyukakyuka okw’enjawulo okuzibu n’okukola ebyuma. Oluvannyuma lw’ekyuma ekiweweeza ku kyuma ekitali kizimbulukuse okufumbirwa, payipu y’ekyuma esobola okukolebwako.
Okutwalira awamu payipu eziweweevu ez’ekyuma ekitali kizimbulukuse zikozesebwa okukola ebizimbe eby’ebyuma, ebyuma ebikola amazzi, ebyuma n’ennimiro endala ez’okufulumya. Mu bitundu by’ebikozesebwa, ebyuma eby’obujjanjabi, ebyuma ebituufu, ebyuma eby’amasannyalaze, eby’omu bbanga, payipu z’amazzi agalina ebisenge ebigonvu n’ebikyusa ebbugumu, payipu eziweereddwa welded zeetaagibwa okuba n’obutuufu obw’obuwanvu obw’ebweru obw’obuwanvu obw’ebweru. Ebyuma bya payipu ebya bulijjo ebiweereddwa welded tebisobola kutuukiriza kyetaagisa kino. Seko Machinery ekutwala okwekenneenya engeri ebyuma bya payipu ebiweereddwa welded n'ensonga z'okufulumya gye bikwata ku dimensional accuracy ya stainless steel welded payipu 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 Ekikosa ku payipu eziweweevu ez’ekyuma ekitali kizimbulukuse. Okukyama okukkirizibwa kwa dayamita (Table 1) n’okukyama kw’obuwanvu bw’ekisenge (Table 2) ebyetaago. Okugumiikiriza kwa dayamita ey’omunda kwa payipu eziweereddwa welded kusinga kukosebwa kugumiikiriza kwa dayamita ya bweru n’okugumira obuwanvu bw’ekisenge. Ekitundu kino tekiyogera ku nsonga y’okugumiikiriza kwa diameter ey’omunda.
.
Okugumiikiriza kw’olutimbe lw’ekyuma, obutuufu bw’ebipimo by’omuzingo gw’okuweta n’ekituli kyagwo.
2) Enfuga y’omuwendo gw’okugerageranya ku butuufu bw’ebipimo bya payipu ey’ebweru eya welded Outer diameter
Omuwendo gw’obunene bwa payipu eya welded eya waggulu ennyo gulina okuba nga munene katono okusinga ogwa payipu eya bulijjo eya welded. Omusingi gw’okusalawo omuwendo gw’okugerageranya guli: 1 Omuwendo gw’okugera obunene gulina okuba omunene okusinga okugumiikiriza kwa dayamita ey’ebweru eya payipu eya welded nga dayamita tennabaawo; 5 Omuwendo gw’okugera obunene ogumala n’ebiseera by’okuyita.
2.3 Obugumu bwa fuleemu y’ekyuma ekigerageranya n’enkola y’obunene bw’ebyuma .
.
2.3.2 Amaanyi agazingulula agakyukakyuka .
1) Puleesa ya yuniti eya wakati
2) Ekitundu ky’okukwatagana
3) Amaanyi agazingulula agakyukakyuka .
2.3.3 Okukyukakyuka kwa laasitiki y’omusingi gw’ekyuma ekikyukakyuka .
2.4 Enkola y’okugera obunene bw’ebyuma okukola ebyuma obutuufu
Okukola ebyuma obutuufu bw’ekyuma ekigera obunene kikwata butereevu ku kugumiikiriza kwa dayamita ey’ebweru kwa payipu eya welded .
Obutuufu bw’obugumu n’obugazi bw’omuguwa gw’ekyuma bukosa obutuufu bwa dayamita ey’ebweru eya payipu eya welded nga tonnaba kugerageranya, naye si nnyo mu nkola y’okugerageranya. Okuyita mu sayizi n’omuwendo gw’okugera obunene bisalibwawo okusinziira ku kugumiikiriza kwa dayamita ey’ebweru kwa payipu eya welded nga tebannaba kugigeraageranya. Okuyita okunene okunene n’omuwendo gw’okugera obunene gwe musingo omukulu ogw’okulongoosa obutuufu bwa dayamita ey’ebweru ey’ekintu ekiwedde mu payipu eya welded. Ensonga enkulu ezikwata ku butuufu bwa dayamita ey’ebweru eya payipu eya welded ze zisinga obunene bw’ekyuma ekikola obunene n’obutuufu bw’okukola ebyuma. Hangao Tech (Ebyuma bya Seko) Precision High-Speed Stainless Steel Industrial Pipe Machine , Model ne Mold Design zifugibwa ddala, era enkola eziwerako omuli okuweta, okukola annealing okumasamasa, okugerageranya okutuufu, n’ebirala bisobola okumalirizibwa ku yintaneeti, ebiyinza okutuukiriza okufulumya okutambula obutasalako okumala essaawa 24. Ebisingawo, nsaba weebuuze ku!
