Nga ffenna bwe tumanyi, payipu z’ekyuma ekitali kizimbulukuse zeetaaga okusiiyibwa n’okusiigibwa nga tezinnaba kuva mu kkolero.
Wabula oluusi kisangibwa nti abakozesa beetaaga okuddamu okukola payipu. Ku bikwata ku payipu, okuggyamu amasavu mu ngeri esinga okuba entuufu kulina okuba okumaliriza okulongoosa enkola ya payipu yonna ey’okuggya amasavu mu kifo oluvannyuma lw’okuteekebwako okuggwa. Okutwalira awamu, omukozi w’ebintu tajja kukkirizibwa kulongoosa payipu, kale nsonga ki ey’okwetaaga omukozi okuggyawo payipu?
Okuggya amasavu mu payipu ey’ekyuma ekitali kizimbulukuse kye ki?
Olw’omutindo gw’amakolero mu ggwanga lyaffe okweyongera n’okukulaakulanya okw’amaanyi okwa petrochemical, natural gas, medical equipment, instrumentation, aviation, aerospace ne projects endala ez’amakolero, ebyetaago bya tekinologiya wa payipu y’ebyuma ebitali bimenyamenya nabyo bigenda byeyongera. Nga obuyonjo bwa payipu, abamu ku bakozesa beetaaga nti tewali buwuka bwa ddembe, obutundutundu obunene obw’enfuufu, welding slag, giriisi n’obucaafu obulala munda.
Mu bino, payipu ya oxygen erina ebyetaago ebikakali ennyo eby’obuyonjo. Payipu za okisigyeni ezisinga zitambuza omukka gwa okisigyeni n’obulongoofu obusukka mu 99.99%, nga puleesa ya waggulu ate ng’ekulukuta mangu. Singa obuyonjo obw’omunda obwa payipu tebusobola kukakasibwa, obungi bw’amafuta n’ebyuma mu payipu mu payipu buyinza okufuumuuka ne butomera omukka omulongoofu ogw’amaanyi, era ennimi z’amasannyalaze ezikoleddwa zijja kuleeta ebivaamu eby’amaanyi ebiyinza okulowoozebwako era n’okutuuka n’okuleetawo akabenje akazibu.
Mu byo, mu nkola y’okufulumya payipu eziweereddwa, enkola y’okuleega munda esobola okugattibwako okulongoosa obuweerero bw’ekisenge eky’omunda ekya payipu eya welded, okukendeeza ku fayiro z’ekyuma n’ebintu ebisigadde ku bbugwe ow’omunda, era bwe kityo ne kikendeeza ku kukulukuta. Hangao Tech (Seko Machinery) erina obumanyirivu mu makolero obusoba mu myaka 20 mu makolero Stainless steel tube inner weld bead leveling equipment , era nga ekuŋŋaanyizza omuwendo omunene ogw’ebikwata ku kukola n’emisango gya bakasitoma, ekisaanira ddala obwesige bwo.
N’olwekyo, okusinziira ku nkola ebyetaago, payipu y’ebyuma ebipya yeetaaga okukozesa enkola y’okuyonja eddagala okuggyawo amafuta n’obucaafu obulala ku bbugwe wa payipu ey’omunda nga ekyuma tekinnatandika. Mu kiseera kye kimu, omugabi era ajja kwetaaga okukendeeza ku payipu.
Mitendera ki egy’okuggya amasavu n’okuyonja payipu za oxygen ez’ekyuma ekitali kizimbulukuse?
Stainless Steel Oxygen Pipeline Okuggya Amasavu mu Kuyonja: Okunaaba Amazzi → Okusiimuula Okuggya Amasavu → Okunaaza Amazzi → Okulongoosa empewo enyigirizibwa (oba nayitrojeni).
Okufuuwa amazzi: Bw’oba ofuuwa amazzi, kozesa ebyuma ebitonotono eby’okwoza amazzi ebya puleesa enkulu okufuuwa, era puleesa efugibwa ku 0.6MPa okukakasa nti obucaafu obuli munda mu payipu buba buyonjo. Ekigendererwa kwe kuggyamu evvu, siliti, okisayidi z’ebyuma ezeetongodde n’obucaafu obulala obutambula mu payipu.
Okusiimuula n’okuggya amasavu mu ngalo: Yiwa omutabula gw’okuyonja n’okuggyamu amasavu mu kifo eky’okwoza, okigatteko mu kigerageranyo, okitabule kyenkanyi nga tonnagukozesa, obisiige enfunda n’enfunda. Mu nkola y’okuyonja, obuyonjo bw’ekintu eky’okuyonja ekiggya amasavu bulina okulondoolebwa. Singa langi y’omusulo gw’okuyonja okuggya amasavu efuuka encaafu, eky’okuggyamu amasavu ekiriwo kisaana okufuluma era eky’okuyonja ekiggyamu amasavu kisaana okuddamu okusengekebwa. Ekigendererwa kwe kuggyawo ebirungo eby’obutonde ebya buli ngeri nga amafuta, graphite, woyiro aziyiza okuzimba mu payipu, okusobola okukakasa nti munda mu payipu eno nnyonjo mu kiseera ky’okuteekebwamu n’okutuukiriza ebyetaago by’okukola ebyuma.
Okufuuwa amazzi: Oluvannyuma lw’okuggyamu payipu, ogifuuwe n’amazzi amangi. Amazzi agakulukuta bwe gafuluma mu payipu nga mayonjo, amazzi agakulukuta gasobola okuggwa. Ekigendererwa ky’okufuuwa amazzi oluvannyuma lw’okuggyamu amasavu kwe kufuuwa ebisigadde ebiggya amasavu mu payipu.
Empewo enyigiriziddwa (oba nayitrojeni) erongoosa: Kozesa empewo enyigirizibwa etaliimu mafuta (oba nayitrojeni) okulongoosa, okukaza munda mu payipu, n’oluvannyuma zinga payipu oba ebitundu n’olugoye oluyonjo olw’akaveera okukakasa obuyonjo obuli munda mu payipu n’okwewala obucaafu obw’okubiri.
Enkola ya payipu ey’ekyuma ekitali kizimbulukuse Enkola y’okukkiriza .
Enkola ya payipu okuggya amasavu ejja kukozesa ekizimbulukusa ekiggya amasavu eragiddwa mu dizayini era nga kyetaagisa okuggya amasavu. Singa tekirambikiddwa mu dizayini, kiyinza okuggyibwamu kaboni tetrachloride okukebera oba okuggya amasavu kulina ebisaanyizo.
Degreased ekyuma ekitali kizimbulukuse payipu packaging .
Oluvannyuma lwa payipu okuggyibwako amasavu n’okuyonja, ebisaanyizo bino wammanga birina okutuukirira:
1) Kozesa ekitangaala kya ultraviolet n’obuwanvu bw’amayengo ga 320-380nm okukebera ekisenge eky’omunda ekya payipu, era tewalina kubaawo giriisi fluorescence.
2) Siimuula ekisenge eky’omunda ekya payipu n’olupapula oluyonjo olweru oluyonjo era olukalu, tewalina kubaawo kalonda wa mafuta ku lupapula.
3) oba kozesa ekizimbulukusa ekiggya amasavu okuzuula nti woyiro alimu tasukka byetaago bya kibiina ekikwasa.
4) Ebiraga eby’ekikugu ebirala ebikwatagana ebiteeseddwa ekibiina ekikwasa.
Enkola y’okuyonja n’okukendeeza ku masavu mu payipu za oxygen ez’ekyuma ekitali kizimbulukuse essa omutindo ku nkola y’okuzimba okuyonja payipu za okisigyeni n’okukendeeza amasavu, erongoosa nnyo obuyonjo obw’omunda obwa payipu za okisigyeni, era nga bwe bukakafu obwesigika obw’okukola obulungi era obulungi mu kukola payipu za okisigyeni. Kisaana okufiibwako n’okukuzibwa abakola payipu ez’ekyuma ekitali kizimbulukuse.
