| Inkqubo yoMveliso wePipe yeNtsimbi engaGciniyo |
Ukuveliswa kombhobho wentsimbi engagqwaliyo kuquka la manyathelo alandelayo: ukukhethwa kwezinto eziluhlaza, ukuthambisa, ukuqhobosha, ukugaya, ukucoca i-asidi, ukuzoba okubandayo, uvavanyo lwe-ultrasonic, kunye nokupakishwa kokugqibela. Inyathelo ngalinye liqinisekisa ukuba umbhobho uhlangabezana nemigangatho ephezulu yomgangatho, ukuchaneka, kunye nokugqitywa komphezulu.
| Uvavanyo loBurhabaxa boMbhobho weNtsimbi Engagqwaliyo |
Uvavanyo loburhabaxa kwiipayipi zentsimbi engagqwaliyo yinkqubo ebalulekileyo yokuhlola esetyenziselwa ukuvavanya umgangatho wokugqitywa komphezulu womphezulu wombhobho wangaphakathi okanye wangaphandle. Uburhabaxa bomphezulu, obuhlala bulinganiswa kwi-Ra (umyinge woburhabaxa), buchaphazela ukusebenza kakuhle kokuhamba kwamanzi, ukumelana nokugqwala, kunye nococeko—ingakumbi kumashishini afana namayeza, ukucubungula ukutya, kunye nokuveliswa kwe-semiconductor. Besebenzisa izixhobo ezichanekileyo ezifana neeprofilometers zomphezulu, abahloli baqinisekisa ukuba umbhobho uyahlangabezana neemfuno ezifunekayo, ezifana ne-Ra ≤ 0.8 µm okanye i-Ra ≤ 0.2 µm, kuxhomekeke kwisicelo. Ukuqinisekisa uburhabaxa bomphezulu obufanelekileyo kuphucula ukusebenza kwemveliso, ucoceko, kunye nokuqina kwayo yonke.

| Uvavanyo lwangoku lwe-Eddy lweetyhubhu zentsimbi engagqwaliyo |
Uvavanyo lwangoku lwe-Eddy yindlela yovavanyo olungatshabalalisiyo (NDT) esetyenziselwa ukufumanisa iziphene zomphezulu kunye nezikufutshane nomphezulu kwiityhubhu zentsimbi engagqwaliyo. Le ndlela isebenza ngokukodwa ekuchongeni imingxunya, imingxuma, kunye nezinye izinto ezingaqhubekiyo ngaphandle kokonakalisa izinto. Ngokufaka intsimi ye-electromagnetic kwityhubhu kunye nokujonga utshintsho ekuhambeni komsinga we-eddy, abahloli banokuvavanya ngokukhawuleza ukuthembeka kodonga lwetyhubhu. Uvavanyo lwangoku lwe-Eddy lusetyenziswa kakhulu ekuveliseni iityhubhu zentsimbi engagqwaliyo ezingenamthungo nezihlanganisiweyo, ngakumbi kwi-heat exchanger, i-boiler, kunye nezicelo zezixhobo. Iqinisekisa ukuthembeka kwemveliso kunye nokuthobela imigangatho yoshishino efana ne-ASTM E426 kunye ne-EN 10246-3.
| Uvavanyo loMxholo weFerrite |
Uvavanyo lomxholo weFerrite yinkqubo ebalulekileyo yokulawula umgangatho kwiipayipi zentsimbi engagqwaliyo, ngakumbi ezo zenziwe ngee-austenitic okanye ii-duplex grades. Olu vavanyo olungonakalisiyo lulinganisa ubungakanani besigaba seFerrite esikhoyo kwizinto zepayipi okanye kwindawo ye-weld ukuqinisekisa ukumelana nokugqwala okufanelekileyo, ukusebenza koomatshini, kunye nokuthembeka kwe-weld. Umxholo weFerrite ogqithisileyo okanye owaneleyo unokukhokelela kwimiba efana nokuqhekeka koxinzelelo lokugqwala okanye ukuqina okunciphileyo. Uvavanyo lwenziwa rhoqo kusetyenziswa iindlela zokungenisa amandla magnetic (umz., iFerrite Scope), kwaye luhambelana nemigangatho efana ne-ASTM E562, ISO 8249, okanye i-AWS A4.2. Kwiinkqubo zepayipi ezisetyenziswa kwiindawo ezibalulekileyo—ezifana namaqonga aselunxwemeni, imikhumbi yoxinzelelo, kunye nezityalo zeekhemikhali—ulawulo lomxholo weFerrite lubalulekile ekuthembekeni nasekukhuselekeni kwexesha elide.

| Isisombululo se-Intanethi sokuNyulwa kweeTubhu zeNtsimbi Engagqwaliyo |
Ukutsalwa kwesisombululo esikwi-intanethi yinkqubo yokunyanga ubushushu eqhubekayo esetyenziswa kwiityhubhu zentsimbi engagqwaliyo ngexesha lemveliso ukuphucula ukumelana kwazo nokugqwala, amandla oomatshini, kunye nokufana kwesakhiwo. Kule nkqubo, iityhubhu zifudunyezwa ngokukhawuleza ukuya kubushushu bokutsalwa kwesisombululo—ngesiqhelo phakathi kwe-1000°C kunye ne-1150°C—kulandelwa kukupholisa okulawulwayo, kusetyenziswa amanzi okanye igesi engasebenziyo. Olu nyango lunyibilikisa ii-carbide precipitates kwaye lubuyisele isakhiwo se-austenitic, esibaluleke kakhulu kwiindidi ezifana ne-304 kunye ne-316. Ngokudibanisa eli nyathelo ngqo kumgca wemveliso, ukutsalwa kwesisombululo esikwi-intanethi kuqinisekisa umgangatho ohambelanayo, kuphucula ukusebenza kakuhle, kwaye kususa imfuneko yokutsalwa kwebhetshi eyahlukileyo.
