Amathegi Omkhiqizo

Ipayipi lensimbi elimnyama, okubizwa nangokuthiipayipi lensimbi yekhabhoni, ipayipi lensimbi elithambile, uhlobo lwamapayipi enziwe ngensimbi ephansi yekhabhoni. Ukubukeka kwayo okumnyama okuhlukile kuvela esikalini se-oxide emnyama esakheka ebusweni bayo ngesikhathi sokukhiqiza.
Ngokuvamile, amapayipi ensimbi amnyama angamapayipi ayindilinga angacutshungulwanga, aphathwa kakhulu ukuze aqedelwe phezulu. Ngenxa yokungabikho kwesembozo esivikelayo, athambekele kakhulu ekugqwaleni, okwenza afaneleke ukusetshenziswa ezindaweni ezomile noma lapho angapendwa khona noma avikelwe ngenye indlela. Aziwa ngamandla awo nokuqina kwawo, amapayipi ensimbi amnyama ayinketho ethandwayo kokubili ezindaweni zokuhlala kanye nezimboni. Afika ngobukhulu obuhlukahlukene kanye nobukhulu, enikeza ukuguquguquka kwezidingo ezahlukene zokwakha kanye nokufakwa.

2. Izinhlobo ezahlukene zamapayipi ensimbi amnyama

Ngokwezinqubo ezahlukene zokukhiqiza, amapayipi ensimbi amnyama ahlukaniswe kakhulu ngamapayipi ensimbi ahlanganisiwe kanye namapayipi ensimbi angenamthungo.

Ipayipi Lensimbi Elihlanganisiwe:Ipayipi lensimbi elihlanganisiwe lenziwa ngokushisela amapuleti ensimbi noma imichilo egoqwe ibe yipayipi. Laziwa nangokuthi ipayipi le-ERW (Electric Resistance Welded). Lolu hlobo lwepayipi luvame ukuba namandla nokuqina okuhle. Inqubo yokukhiqiza ipayipi lensimbi elihlanganisiwe ilula kakhulu, futhi ingakhiqiza izingxenye zepayipi ezinde ngezindleko eziphansi.

Ipayipi Lensimbi Elingenamthungo:Ipayipi lensimbi elingenamthungo lenziwa ngenqubo yokugoqa eshisayo noma ebandayo ngaphandle kwemithungo ehlanganisiwe. Lolu hlobo lwepayipi lunamandla aphezulu kanye nokuphepha ngaphansi kokucindezeleka okuphezulu kanye nezimo ezimbi kakhulu ngoba alunawo amaphuzu abuthakathaka (njengokugoqa).

3. Iyini ipayipi lensimbi emnyama?

Ipayipi elimnyama lisetshenziswa kabanzi ezinhlotsheni ezahlukene zokusebenza, okuhlanganisa amapayipi, ukusatshalaliswa kwegesi, kanye nokusekelwa kwesakhiwo.

Ipayipi lensimbi elingenamthungoikhiqizwa ngaphandle kwemithungo noma ukushibiliza, okuthuthukisa amandla ayo futhi kwenze kube yindlela ephephile yokuthutha amagesi noketshezi ngaphansi komfutho ophezulu. Lolu hlobo lwepayipi lubaluleke kakhulu ekusetshenzisweni lapho ubuqotho besakhiwo bubaluleke khona, njengasemapayipini kawoyela negesi.
Ngokolunye uhlangothi,ipayipi lensimbi elihlanganisiwe elimnyamaivame ukusetshenziswa ezinhlotsheni ezahlukene zokusebenza, okuhlanganisa amapayipi amanzi, izinhlelo zokudlulisa igesi kanye nezifafaza umlilo. Izakhiwo zayo ezingashisi umlilo zenza ifanelekele izinhlelo ezinjalo, lapho ukuthembeka nokuphepha kubaluleke kakhulu.

4. Ukulawulwa Kwekhwalithi Yamapayipi Amnyama Nokulethwa

1) Ngesikhathi sokukhiqiza nangemva kokukhiqiza, abasebenzi be-QC abanolwazi olungaphezu kweminyaka emi-5 bahlola imikhiqizo ngokungahleliwe.
2) Ilabhorethri egunyaziwe kazwelonke enezitifiketi ze-CNAS
3) Ukuhlolwa okwamukelekayo okuvela kumuntu wesithathu oqokiwe/okhokhelwe ngumthengi, njenge-SGS, i-BV.
4) Kuvunywe yiMalaysia, i-Indonesia, iSingapore, iPhilippines, i-Australia, iPeru kanye ne-UK. Sinezitifiketi ze-UL /FM, ISO9001/18001, FPC.
