Fa'aaogāga
E masani ona faʻaaogaina e fai ai paipa uʻamea uʻamea maualuga, paipa fesuiaʻi vevela, paipa ausa maualuga mo suauʻu ma pisinisi vailaʻau.
Vasega Autu
Vasega o paipa u'amea maualuga: P1,P2,P5,P9,P11,P22,P91,P92 etc
Mo paipa u'amea A335, maketi autu o Initia. Mo Initia Maketi e masani ona manaʻomia le IBR. i aso nei o le a faʻaalia le IBR mo faʻamatalaga.
O Tulafono Faʻatonu a Initia (INDIA BOILER REGULATIONS, o loʻo taʻua mulimuli ane o le IBR) o loʻo faʻamaonia manino ai o pusa, vaʻa mamafa, paipa, valve, mea mata (papatusi, pa, castings, forgings) e auina atu i Initia e manaʻomia le asiasia e le CBB ofisa fa'atagaina e asiasia. O tagata asiasi faʻatagaina e faʻatautaia suʻesuʻega faʻataʻitaʻiga ma suʻesuʻega faʻagasologa o gaosiga e tusa ai ma le IBR, ma faʻatautaia asiasiga faʻapipiʻi i luga ole laiga ma le resitalaina aʻo leʻi ulufale i le maketi Initia. I le taimi lava e tasi, e manaʻomia e le au gaosi oloa ona tuʻuina atu IBR Forms eseese e pei o le gaosiga, faʻapipiʻi ma meafaitino faʻamaonia e tusa ai ma manaʻoga IBR. E faatoa mafai ona tu'uina atu le fa'atagaga pe a uma ona sainia e le lala sooupu fa'atagaina e asiasia.
O le Indian Boiler Code o loʻo faʻamaonia manino ai o pusa ma vaʻa faʻamalosi e gaosia i atunuu e ese mai i Initia e manaʻomia le suʻesuʻeina ma le faʻamaonia o le IBR, ma e tatau ona faʻatagaina e le CBB ofisa asiasia lona tolu. O le mea lea, o le pasia o le IBR certification o se "tusifolau" mo le kamupani e ulufale atu i le maketi Initia.
I le taimi nei, o poloketi a kamupani faʻainisinia i totonu o Initia e masani lava ona tuʻuina atu e le tagata lava ia eletise eletise eletise eletise, ma faʻalavelave foi kamupani faʻafaigaluega. O oloa e feso'ota'i ma va'a fa'amalosi e tele lava: poloketi eletise, konekarate lautele EPC mo kamupani inisinia; auina atu tuusao o boilers, uila afi, eletise fesoasoani, ma isi; nisi o va'a fa'amalosi e fa'aaogaina i fale gaosi oloa; valve, paipa ma isi vaega; paipa uamea, ipu uamea ma isi mea mata.
Faʻatasi ai ma le fesoasoani a le poto masani faʻamaonia pisinisi, Yunquan Testing e mafai ona tuʻuina atu auaunaga faʻapitoa ile asiasiga a le IBR, aʻoaʻoga masani, aʻoaʻoga a le aufaigaluega, faʻatalanoaga faʻapitoa ma iloiloga, faʻamaonia faʻamaonia ma le faʻagasologa o le faʻagasologa o agavaʻa, ma tuʻuina atu le tausisia o le CBB faʻatagaina ofisa asiasia. Tusi pasi, mo se faʻataʻitaʻiga, FORM certificate, IBR welder certificate, etc.
