Umbhobho wentsimbi yeyona projekthi isetyenziswa kakhulu kumbhobho werhasi. Iinzuzo zayo eziphambili zezi: amandla aphezulu, ukuqina okulungileyo, ukuthwala uxinzelelo, ukuxhathisa impembelelo kunye nokuqina, iplastiki enhle, i-welding elula kunye nokulungiswa kwe-thermal, ubukhulu bodonga buncinci, ukugcina isinyithi. Kodwa ukunganyangeki kwayo komhlwa, kufuneka ibe nemilinganiselo efanelekileyo yokuchasa umhlwa.

Imibhobho yentsimbi yeepayipi zegesi kwisixeko esikhulu semibhobho yentsimbi engenamthungo kunye ne-welded kwiindidi ezimbini. Umbhobho wentsimbi ongenamthungo wamandla aphezulu, kodwa unciphise inkqubo yokuvelisa kunye neendleko ngombhobho wentsimbi obubanzi obuncinci DN200 ngezantsi. Iindidi ezongezelelekileyo zemibhobho yentsimbi edityanisiweyo, ukuwelda kunokwahlulwa ngomthungo othe ngqo wemibhobho yentsimbi kunye neentlobo zemibhobho yentsimbi edityanisiweyo. Phakathi kwazo, umbhobho wentsimbi odityanisiweyo othe tye (emva koku ubizwa ngokuba ngumbhobho wokuthunga othe tye) ukwabandakanya umbhobho wentsimbi we-LSAW kunye ne-high frequency resistance welding (RW) umbhobho wentsimbi kunye nezinye iintlobo. Umbhobho wentsimbi odityanisiweyo ongu-Spiral (umbhobho wentsimbi ye-saw) ngumbhobho we-spiral we-arc odityanisiweyo odityanisiweyo (HSAW).

Umthungo othe tye kunye nenkqubo yokwenziwa kombhobho ojikelezayo iyathelekiswa, eyokuqala inenzuzo yoku:
① Inkqubo yokwenziwa kombhobho ojikelezayo ukumisela uxinzelelo lwabo olushiyekileyo lukhulu kunombhobho womthungo othe tye, umbhobho othe tye womthungo onesiphumo esipheleleyo senkqubo yokwandisa, uxinzelelo olushiyekileyo lusondele ku-zero, ngelixa i-spiral ingenako ukwenza oku;

② Icala elingalunganga le-spiral weld ubukhulu becala kuluhlu lwe-1.1 ~ 1.2mm, umgangatho ufuna ubungakanani becala elingalunganga lodonga ukuya ngaphantsi kwe-10% kwiityhubhu ezinodonga olucekethekileyo, icala elingalunganga linzima ukuhlangabezana neemfuno eziqhelekileyo, kwaye umbhobho womthungo othe ngqo awukho Le ngxaki;

③ Xa kuthelekiswa nombhobho womthungo othe tye, ukuhamba komgca we-spiral weld kumbi, uxinzelelo olukhulu loxinzelelo;

④ ubushushu bekhoyili kwindawo echaphazelekayo inkulu kunombhobho womthungo othe tye, kwaye ubushushu bombhobho bommandla ochaphazelekayo sisitshixo somgangatho;

⑤ ukuchaneka kwejiyometri evunguzayo, ukuya kwindawo yokwakha, njengeqabane, ukuwelda kuzisa ubunzima.
