Ukusetshenziswa okuvamile kweenezindonga eziwugqinsi amashubhu angenamthungokumele yenze umsebenzi ohambisanayo wokunqanda ukugqwala kanye nomsebenzi wokwelapha ukugqwala. Umsebenzi ojwayelekile wokulwa nokugqwala uhlukaniswe izinqubo ezintathu:

1. Ukuqeda ukugqwala kwamapayipi.

Ngaphambi kokudweba, ingaphezulu lepayipi kufanele lihlanzwe ngamafutha, i-slag, ukugqwala, nothuli lwe-zinc. Izinga lekhwalithi yomkhiqizo ngu-Sa2.5.

2. Ngemva kokwelashwa kokugqwala ebusweni bepayipi, faka ijazi eliphezulu, futhi isikhawu phakathi kwabo akufanele sidlule amahora angu-8. Uma usebenzisa i-topcoat, i-base surface kufanele yome futhi i-topcoat kufanele ibe iyunifomu, iyindilinga futhi ingabi nezigaxa nama-bubbles emoyeni. Zombili izinhlangothi zepayipi akufanele zixutshwe phakathi kobubanzi obungu-150 ~ 250mm.

3. Ngemuva kokuthi ijazi langaphezulu lomile futhi liqinile, sebenzisa upende bese ubopha indwangu ye-fiberglass, futhi isikhawu phakathi kwejazi eliphezulu nopende akufanele sidlule amahora angu-24.

Ukuqhekeka kweshubhu yensimbi engenamthungo enezindonga eziwugqinsi:

Kuyo yonke inqubo yokusetshenziswa kweshubhu lensimbi engenamthungo enezindonga eziwugqinsi ngezinye izikhathi, indawo engaphezulu kwesinye isikhathi ihlangabezana nokuqhekeka okuphambene. Kunezizathu eziningi zalokhu. Ngizokunikeza ukuhlaziya okuningiliziwe ngezansi.

Uma ishubhu elingenamthungo elinezindonga eziwugqinsi likhubazekile kancane phakathi nayo yonke inqubo yokukhipha, indawo yangaphakathi nengaphandle izobangela ingcindezi eyengeziwe ekudonseni kwangaphakathi okucindezelayo. Ngalesi sikhathi, ngenxa ye-deformation empofu permeability, ukuthambekela kokunwetshwa kwendawo yangaphandle kukhulu kunesendlalelo sangaphakathi, ngakho-ke indawo yangaphandle izobangela ukucindezeleka okwengeziwe kokucindezela, futhi indawo yangaphakathi izobangela ukucindezeleka okwengeziwe. Uma ukucindezelwa okuqinile okwengeziwe endaweni engaphakathi kunethonya elikhulu, ngokuyisisekelo ukucindezeleka okuqinile kanye nokucindezeleka okuqhubekayo okuqhubekayo kungangezwa ndawonye, ​​okuzodlula amandla acindezelayo eshubhu lensimbi engenamthungo enezindonga eziwugqinsi, okuholela ekuqhekekeni okuvundlile kwengaphakathi. phezulu.

Ngaphansi kwamazinga ahambisanayo emishini yesakhiwo, ukunciphisa izici ezihlukahlukene zokuwohloka kwepulasitiki ngesikhathi sokukhiqizwa nokucutshungulwa kwamapayipi ensimbi angenamthungo anezindonga eziwugqinsi kuzokwandisa ithuba lokuqhekeka kwangaphakathi okuphambene. Ngakho-ke, ekukhiqizeni amashubhu ensimbi angenamthungo aminyene, ikhwalithi yokucisha. Kubaluleke kakhulu ukususa i-alkaline brittleness.

Ngaphezu kokucindezeleka kwe-radial eyengeziwe, kukhona ukucindezeleka kwe-radial eyengeziwe phakathi nayo yonke inqubo yokususa. Ukuqhekeka kwe-longitudinal kubangelwa ingcindezi eyengeziwe ye-radial tensile eyenziwa ngesikhathi sokuthulula.
