Ukuhanjiswa ngokukhawuleza Umgangatho oPhakamileyo ongenamthungo weCarbon Steel Boiler Tube/Pipe ASTM A192
Sinyanzelisa ukubonelela ngemveliso yomgangatho olungileyo ngengqikelelo elungileyo yeshishini, umvuzo onyanisekileyo kunye noncedo olulungileyo nolukhawulezayo. ayizokukuzisela kuphela iprimiyamu yomgangatho wemveliso okanye inkonzo kunye nenzuzo enkulu, kodwa eyona nto ibalulekileyo idla ngokuhlala kwimakethi engapheliyo yonikezelo oluKhawulezayo Umgangatho oPhakamileyo ongenamthungo weBoiler yeCarbon Steel Tube/Pipe.I-ASTM A192, Ukususela ekubeni iyunithi yokuvelisa isungulwe, ngoku sizibophelele kwinkqubela phambili yempahla entsha. Kunye nesantya sezentlalo nezoqoqosho, siza kuqhubeka ukuqhubela phambili umoya “wokugqwesa okuphezulu, ukusebenza kakuhle, ukusungula izinto ezintsha, imfezeko”, kwaye sihlale nomgaqo wokusebenza “wetyala ekuqaleni, umthengi wokuqala, umgangatho olungileyo ogqwesileyo”. Siza kuvelisa ikamva elihle elibonakalayo kwimveliso yeenwele kunye namaqabane ethu.
Sinyanzelisa ukubonelela ngemveliso yomgangatho olungileyo ngengqikelelo elungileyo yeshishini, umvuzo onyanisekileyo kunye noncedo olulungileyo nolukhawulezayo. ayizi kukuzisela kuphela iprimiyamu yemveliso okanye inkonzo kunye nenzuzo enkulu, kodwa eyona nto ibalulekileyo idla ngokuhlala kwimarike engapheliyo.I-ASTM A192, Inkampani yethu ibisoloko igxininisa kumgaqo woshishino “wobunjani, uNyaniseko, kunye noMthengi kuQala” esithe ngawo saphumelela ukuthenjwa ngabaxumi basekhaya nakwamanye amazwe. Ukuba unomdla kwintengiso yethu, akufanele ungathandabuzi ukuqhagamshelana nathi ngolwazi oluthe vetshe.

Imfuneko yoVavanyo
Uvavanyo lweHydraustatic:
Umbhobho weNtsimbi kufuneka uVavanywe ngokweHydraulically enye nenye. Uxinzelelo oluphezulu lovavanyo luyi-20 MPa. Ngaphantsi koxinzelelo lovavanyo, ixesha lokuzinzisa kufuneka lingabi ngaphantsi kwe-10 S, kwaye iPipe yensimbi akufanele ivuze. Okanye uVavanyo lweHydraulic lunokuthi lutshintshwe nguVavanyo lwangoku lwe-Eddy okanye uvavanyo lokuvuza kweMagnetic Flux.
Uvavanyo olungonakaliyo:
Imibhobho efuna uPhononongo olungakumbi kufuneka ihlolwe ngokwe-Ultrasonically nganye nganye. Emva kokuba uThethathethwano lufuna imvume yeQela kwaye luchazwe kwiKhontrakthi, olunye uvavanyo olungabhubhisi lunokongezwa.
Uvavanyo lokucaba:
Iityhubhu ezinoMda waNgaphandle oMkhulu kune-22 mm ziya kuHlelelwa kuVavanyo lokuNcandwa. Akukho kuDelamination kubonakalayo, amabala amhlophe, okanye ubumdaka obunokuthi kwenzeke ngexesha lovavanyo lulonke.
Uvavanyo lokuqina:
Ngombhobho wamaBanga P91, P92, P122, kunye neP911, Brinell, Vickers, okanye Rockwell Ukuqina kovavanyo kuya kwenziwa kwiSampulu kwiLoti nganye.
