Ukubuka konke

• Umzimba onengxenye eyodwa

• Ukungena Okuphezulu Kokulungiswa Kwe-inthanethi

• Umklamo Ongaguquki

• Isiqu Esilwa Nokuqhuma

• Ukuzikhulula Ekucindezelweni Komgodi

• Ukuvimba Okuphindwe Kabili Nokopha (DBB)

• Isivikelo Somlilo ku-API 607

• Inketho Yomsuka Ongaphansi Komhlaba Nowesicu Esinwetshiwe

• Ukupakisha okuphansi kokukhishwa komoya

• Umjovo we-sealant ophuthumayo

a) Ukuklama Nokukhiqiza: I-API 6D, BS 5351

b) Ubuso Nobuso: API B16.10, API 6D, EN 558, DIN 3202

c) Ukuxhumana Kokugcina: ASME B16.5, ASME B16.25, EN 1092, JIS B2220

d) Ukuhlolwa Nokuhlolwa: I-API 6D, EN 12266, i-API 598

I-NSEN ilandela ngokuqinile ukulungiswa kwamahhala, ukushintshwa kwamahhala kanye nezinsizakalo zokubuyiselwa kwamahhala zingakapheli izinyanga eziyi-18 ngemuva kokuthi ivalvu isisebenzile noma izinyanga eziyi-12 ngemuva kokufakwa nokusetshenziswa epayipini ngemuva kokusebenza kwangaphambilini (okuzofika kuqala). 

Uma kwenzeka ivalvu yehluleka ngenxa yenkinga yekhwalithi ngesikhathi sokusetshenziswa epayipini ngaphakathi kwesikhathi sewaranti yekhwalithi, i-NSEN izohlinzeka ngensizakalo yewaranti yekhwalithi yamahhala. Insizakalo ngeke iphele kuze kube yilapho ukwehluleka sekulungisiwe futhi ivalvu ivame ukusebenza futhi iklayenti lisayina incwadi yokuqinisekisa.

Ngemva kokuphela kwesikhathi esishiwo, i-NSEN iqinisekisa ukuhlinzeka abasebenzisi ngezinsizakalo zobuchwepheshe ezisezingeni eliphezulu ngesikhathi noma nini lapho umkhiqizo udinga ukulungiswa nokunakekelwa.
