Isayensi edumile: Axhunywe kanjani amapayipi obunjiniyela bensimbi engagqwali?

Njengento ebalulekile esetshenziswa kabanzi ezimbonini zokwakha, ezobunjiniyela, nezokukhiqiza, ubuchwepheshe bokuxhuma amapayipi ensimbi engagqwali bungenye yezihluthulelo zokuqinisekisa ikhwalithi yephrojekthi nempilo yesevisi. Umhleli we insimbi engagqwali ipayipi umenzi, yethula kafushane izindlela zokuxhuma zamapayipi ensimbi engagqwali, okuhlanganisa i-welding, uxhumano lwentambo, uxhumano lwengcindezi, njll., ukukusiza ukuthi ukhethe indlela engcono kakhulu yokuxhuma efanele iphrojekthi yakho.

1. Ukuxhumana kwe-Welding

I-Welding iyindlela evame ukusetshenziswa kakhulu yokuxhuma amapayipi ensimbi engagqwali. Ingakwazi ukuzuza ukuxhumana okuqinile ngomthamo ophezulu wokuthwala umthwalo kanye nokumelana nokugqwala. Ukuxhumana okuhlanganisiwe kwamapayipi ensimbi engagqwali kungahlukaniswa ngezinhlobo ezimbili: i-welding manual kanye ne-automated welding. I-manual welding ifaneleka kumaphrojekthi amancane noma ukuxhumeka kwamapayipi okumise okukhethekile, kuyilapho ukushisela okuzenzakalelayo kulungele amaphrojekthi amakhulu kanye nokuxhumeka kwamapayipi okuphindaphinda kakhulu.

Uma ufaka amapayipi ensimbi engagqwali, udinga ukunaka amaphuzu alandelayo: Okokuqala, khetha indlela efanele yokushisela. Ezivamile zihlanganisa i-TIG welding, i-MIG welding, i-welding kagesi, njll. Okwesibili, qinisekisa ukuhlanzeka kwendawo yokushisela ukuze ugweme ukuba khona kothuli, ukungcola nokunye ukungcola. Okokugcina, ukushisa kwangaphambi kokushisa nokulungiswa kwemingcele ye-welding kufanele kwenziwe ngaphambi kwe-welding ukuze kuqinisekiswe ikhwalithi ye-welding namandla okuxhuma.

2. Ukuxhumana okunentambo

Ukuxhumana okunentambo kuyindlela elula nethembekile yokuxhuma amapayipi ensimbi engagqwali. Ifanele amaphrojekthi wobunjiniyela anamadayimitha amapayipi amancane kanye nezingcindezi eziphansi. Ukuxhumana kwentambo yepayipi yensimbi engenasici kuhlukaniswe izinhlobo ezimbili: izintambo zangaphakathi kanye nezintambo zangaphandle. Izindinganiso ezivamile zokuxhuma intambo zihlanganisa intambo ye-Willai eyamukelwa emhlabeni wonke, intambo yepayipi elicishiwe elivame ukusetshenziswa ekhaya, njll.

Lapho wenza ukuxhunywa okunentambo kwamapayipi ensimbi engagqwali, udinga ukunaka amaphuzu alandelayo: Okokuqala, ukuvaleka kwezixhumo ezinentambo kubi, ngakho-ke ama-sealant noma ama-gaskets kudingeka asetshenziselwe ukuwavala ukuvimbela ukuvuza kwamanzi. Okwesibili, ukuxhumana okufakwe imicu kufanele kufakwe ngokunaka okusesilinganisweni, kungakhululeki kakhulu ukuze kubangele ukuvuza noma kuqine kakhulu ukuze kubangele ukuwohloka. Okokugcina, qaphela lapho uqaqa ukuze ugweme ukulimaza noma ukuhluza imicu.

3. Ukuxhumeka kwengcindezi

Ukuxhumeka kwengcindezi kuyindlela yokuxhuma amapayipi ensimbi engenasici ngokusebenzisa i-pre-pressurization. Ifanele amaphrojekthi anamadayimitha amapayipi amakhulu kanye nezingcindezi eziphakeme. Kunezinhlobo ezimbili eziyinhloko zokuxhunywa kwengcindezi yamapayipi ensimbi engagqwali: uxhumo lwesokhethi nokuxhumeka kwe-flange. Uxhumano lwesokhethi ukufaka ipayipi embobeni yokuxhuma bese ulivala ngaphansi kwengcindezi, kuyilapho uxhumano lwe-flange kuwukuxhuma amapayipi ngokusebenzisa ama-flange namabhawodi.

Lapho wenza ukuxhumeka kwengcindezi yamapayipi ensimbi engagqwali, udinga ukunaka amaphuzu alandelayo: Okokuqala, khetha izinto ezifanele zokuvala uphawu. Ezivamile zihlanganisa ama-gaskets enjoloba, ama-gaskets e-PTFE, njll. Okwesibili, izidingo zokufaka kufanele zilandelwe ngokuqinile ukuze kuqinisekiswe ukuvala nokuphepha koxhumano. Okokugcina, ukuhlolwa kufanele kwenziwe ngaphambi kokuxhumeka ukuze kuqinisekiswe ukwethembeka nokumelana ne-voltage yokuxhuma.

Ngamafuphi, uxhumano lwepayipi yensimbi engagqwali ubuchwepheshe buyisixhumanisi esibalulekile ekuqinisekiseni ikhwalithi yephrojekthi kanye nempilo yesevisi. Kungakhathaliseki ukuthi uxhumano olushiselwe, uxhumano olunentambo, noma uxhumano lwengcindezi, ludinga ukusetshenziswa ngezindlela ezifanele kanye nezidingo. Ukukhetha indlela yokuxhuma efanele akukwazi nje ukuqinisekisa ukuzinza nokuqina kwephrojekthi kodwa futhi kuthuthukise ukusebenza kahle nokuphepha komsebenzi. Ngethemba ukuthi lesi sihloko siwusizo kumaphrojekthi akho wobunjiniyela!
