Yintoni endimele ndiyinikele ingqalelo xa usebenzisa i-flange ye-welding ye-neck butt?

Zonke isinyithi ngeintamo butt welding flangeizixhobo ziya kusabela nge-oksijeni ye-atmospheric, zenze ifilimu ye-oxide phezu komhlaba. Imveliso kufuneka ifakwe ngokwemiyalelo, ukwenzela ukuba kuqinisekiswe ukusebenza okuqhelekileyo kwemveliso kwixesha elizayo. Namhlanje, kukho iimodeli ezininzi zeemveliso. Ngokuqhubeka nokuvela kwezinto ezintsha zenzululwazi kunye nobuchwepheshe, iimveliso ezihlaziyiweyo ziya ngokuya zihambelana neemfuno zabantu. Ngokukodwa, iimveliso zenkampani zihlala ziphucula ukusebenza.

Ukuba iintamo butt welding flangeidityaniswe ngohlobo olufanayo lwe-electrode yensimbi engenasici ye-chromium (G202, G207), kufuneka ifudunyezwe ibe ngaphezu kwama-300 emva kwe-welding, kwaye ipholile ngokukhawuleza malunga ne-700. Ukufakwa kwe-weld flange kufuneka kusetyenziswe.

Yintoni endimele ndiyinikele ingqalelo xa usebenzisa i-flange ye-welding ye-neck butt?

1. FlangeUkufakwa kunye ne-neck butt welding inokumelana nokugqwala okulungileyo kunye nokumelana ne-oxidation kwintonga ye-welding kunye ne-butt welding flange, esetyenziswa ngokubanzi kwisichumisi sekhemikhali, imboni yeekhemikhali, i-petroleum kunye nokuveliswa koomatshini bezonyango.

2. Ngexesha le-welding of flangeukufakwa kunye ne-neck butt welding, i-carbides ihlanjululwa ngokufudumeza okuphindaphindiweyo, okubangelwa ukuhla kweempawu zomatshini kunye nokuxhathisa ukubola.

3. Ukuqinisa umgangatho we-American flange kunye ne-neck butt welding flange fittings inkulu emva kwe-welding kwaye kulula ukuyiqhekeza. Ukuba uhlobo olufanayo lwe-electrode yensimbi engenasici ye-chromium (G202, G207) kufuneka ibe ngaphezu kwama-300 ukufudumeza kunye ne-700 yonyango olucothayo lokupholisa emva kwe-welding. Ukuba i-weldment ayikwazi ukuphathwa ngobushushu emva kwe-welding, i-electrode ene-neck weld flange fittings (A107, A207) kufuneka ikhethwe.

Ukuzalwa kweemveliso kubomi bomntu kuye kwazisa ubuninzi bezinto ezilula, iimveliso azitshintshi, kodwa ngophuhliso lwesayensi kunye nobuchwepheshe obutsha. Ngoko ke, kubaluleke kakhulu ukukhetha imveliso efanelekileyo ngenzuzo yakho.

Ngenxa yokumelana ne-corrosion enhle yensimbi engenasici, amalungu esakhiwo anokugcinwa ngokusisigxina ngokunyaniseka koyilo lobunjineli. I-Chrome stainless steel stamping flanges nayo idibanisa amandla omatshini kunye ne-ductility ephezulu kwaye kulula ukuyivelisa ukuhlangabezana neemfuno zabayili bezakhiwo kunye nabayili bezakhiwo.
