Incwadi yemiyalelo yenkqubo yokufaka ivalvu yebhabhathane yombane

1. Beka ivalvu phakathi kweeflange ezimbini ezifakelweyo (ivalvu yebhabhathane yeflange idinga indawo yegasket efakelweyo ngaphambili kuzo zombini iziphelo)

2. Faka iibholiti kunye neenathi kuzo zombini iziphelo kwimingxuma yeflange ehambelanayo kuzo zombini iziphelo (indawo yegasket yevalvu yebhabhathane yeflange kufuneka ilungiswe), uze uqinise iinathi kancinci ukuze ulungise ukuthamba komphezulu weflange.

3. Lungisa i-flange kumbhobho ngokuwelda nge-spot welding.

4. Susa ivalvu.

5. Shicilela iflange ngokupheleleyo kumbhobho.

6. Emva kokuba ijoyinti yokuwelda ipholile, faka ivalvu ukuqinisekisa ukuba ivalvu inendawo eyaneleyo yokushukuma kwiflange ukuthintela ivalvu ukuba ingonakali, kwaye uqinisekise ukuba ipleyiti yebhabhathane inomgangatho othile wokuvula (ivalvu yebhabhathane yeflange kufuneka yongeze i-gasket yokutywina); lungisa indawo yevalvu kwaye uqinise zonke iibholithi (qaphela ukuba ungasongi kakhulu); vula ivalvu ukuqinisekisa ukuba ipleyiti yevalvu inokuvula kwaye ivale ngokukhululekileyo, uze wenze ipleyiti yevalvu ivuleke kancinci.

7. Qinisa zonke iinati ngokulinganayo.

8. Qinisekisa ukuba ivalvu iyakwazi ukuvula nokuvala ngokukhululekileyo. Qaphela: qiniseka ukuba ipleyiti yebhabhathane ayichukumisi umbhobho.

Qaphela: indlela yokuvula nokuvala indlela yokulawula ilungisiwe xa ivalvu yebhabhathane yombane iphuma kwifektri. Ukuze kuthintelwe icala elingalunganga xa umbane uqhagamshelwe, umsebenzisi kufuneka avule ngesandla ukuya kwindawo enesiqingatha (50%) ngaphambi kokudibanisa umbane, aze emva koko acinezele iswitshi yombane ukujonga iswitshi nokujonga icala lokuvula ivalvu yesalathiso sevili lesalathisi.
