Wonke umntu uyazi ukuba xa sithutha zonke iintlobo zezinto, kufuneka sihlolisise ngenyameko, ngokukodwa izinto ezinkulu, ezifuna ukujongwa kabini okanye kathathu ngaphambi kokungena okanye ukuphuma kwindawo yokugcina impahla. Ke kufuneka ujongwe njani umbhobho wentsimbi ochasene nomhlwa xa ungena naxa uphuma kwindawo yokugcina impahla? Yintoni ekufuneka iqwalaselwe ekuthuthweni kwayo nasekulayisheni nasekukhupheni? Makhe ndikwazise.

1) Indlela yokukhangela ukungena kunye nokuphuma kweepayipi zensimbi ezichasene ne-corrosion spiral?

1. Ukuhlola ingcambu-nge-root-root-root-root-root-root-root-root-root-root-root-root-root-root-root-root-root-root and smooth, ngaphandle kwamaqamza amnyama, i-pitting, imibimbi kunye nokuqhekeka ngokubanzi, kunye nombala wonke kufuneka ube yinto efanayo. Akufuneki kubekho ukubola okugqithisileyo kumphezulu wombhobho.

2. Iqondo lokugoba lombhobho wensimbi kufuneka libe ngaphantsi kwe-0.2% yobude bombhobho wensimbi, kwaye i-ellipticity yayo kufuneka ibe ngaphantsi okanye ilingane ne-0.2% yobubanzi obungaphandle bombhobho wensimbi. Ukungalingani kwendawo ebusweni bombhobho wonke ungaphantsi kwe-2mm.

2) Yintoni ekufuneka ihlawulwe ingqalelo ekuthuthweni nasekulayisheni nasekukhupheni imibhobho yensimbi echasene ne-corrosion spiral?

1. Ukulayisha kunye nokukhupha: sebenzisa i-spreader engonakalisi i-nozzle, kwaye ungonakalisi i-anti-corrosion layer. Zonke izixhobo zokwakha kunye nezixhobo ngexesha lokulayisha kunye nokukhulula. kufuneka ihambelane nemimiselo. phambi kokulayisha. Ibakala lokuchasana ne-corrosion, izinto eziphathekayo kunye nobukhulu bodonga lwemibhobho kufuneka luhlolwe kwangaphambili, kwaye alufanelekanga ukuxuba.

2. Ezothutho: Kufuneka kufakwe ithrust baffle phakathi kwenqwelwana kunye nekhebhu. Xa uhambisa umbhobho we-anti-corrosion spiral, kuyimfuneko ukuwubopha ngokuqinileyo kwaye uthathe amanyathelo okukhusela kwi-anti-corrosion layer ngexesha. Amaphepha erabha okanye ezinye izinto ezithambileyo ziya kubonelelwa njengeepadi phakathi kwemibhobho yokunqanda ukudumba kunye nesakhelo sesithuthi okanye iindawo eziphakamileyo, naphakathi kwemibhobho yokunqanda ukudumba.
