Umehluko Phakathi kwe-EN877:2021 ne-EN877:2006

Izinga le-EN877 lichaza izidingo zokusebenza kwe-amapayipi ensimbi acishiwe, izinto zokufakafuthiizixhumi zaboesetshenziswa ezinhlelweni zokudonsa amanzi adonsela phansi ezakhiweni.EN877:2021inguqulo yakamuva yendinganiso, ethatha indawo yenguqulo yangaphambilini ye-EN877:2006. Umehluko omkhulu phakathi kwezinguqulo ezimbili maqondana nokuhlolwa umi kanje:

1. Ububanzi bokuhlola:

I-EN877:2006: Ihlola kakhulu izakhiwo zemishini kanye nezakhiwo zokuvala amapayipi kanye nezinto zokufaka.

I-EN877:2021: Ngokusekelwe esivivinyweni sokuqala, kwengezwe izidingo zokuhlola zokusebenza kokuvikela umsindo, ukumelana nokugqwala kwamakhemikhali, ukumelana nomlilo nezinye izici zohlelo lwamapayipi.

2. Izindlela zokuhlola:

I-EN877:2021 ibuyekeza ezinye izindlela zokuhlola ukuze zizenze zibe zesayensi futhi zibe nengqondo, njenge:Ukuhlolwa kokumelana nokugqwala ngamakhemikhali: Kusetshenziswa izixazululo ezintsha zokuhlola nezindlela zokuhlola, njengokusebenzisa isisombululo se-pH2 sulfuric acid esikhundleni sesisombululo sokuqala se-hydrochloric acid, kanye nokwengeza izivivinyo zokumelana nokugqwala ngamakhemikhali engeziwe.

Ukuhlolwa kokusebenza kwe-acoustic: Izidingo zokuhlola ezengeziwe zokusebenza kokuvikela umsindo ohlelweni lwamapayipi, njengokusebenzisa indlela yezinga lokucindezela umsindo ukukala ukuvikela umsindo ohlelweni lwamapayipi.

Ukuhlolwa kokusebenza komlilo: Izidingo zokuhlolwa ezengeziwe zokusebenza kokumelana nomlilo kohlelo lwamapayipi, njengokusebenzisa indlela yomkhawulo wokumelana nomlilo ukuhlola ubuqotho bohlelo lwamapayipi ngaphansi kwezimo zomlilo.I-EN877:2021 isebenzisa upende onezinga lokumelana nomlilo le-A1

3. Izidingo zokuhlolwa:

I-EN877:2021 inyuse izidingo zokuhlolwa kwezinye izinkomba zokusebenza, njenge:Amandla okuthamba: akhuphukile kusuka ku-150 MPa kuya ku-200 MPa.
Ukwelulwa: kukhuphuke kusuka ku-1% kuya ku-2%.

Ukumelana nokugqwala kwamakhemikhali: Izidingo ezengeziwe zokumelana nokugqwala zezinto eziningi zamakhemikhali, njengezidingo zokumelana nokugqwala kwezinto ze-alkaline ezifana ne-sodium hydroxide kanye ne-potassium hydroxide.

4. Umbiko wokuhlolwa:

I-EN877:2021 inezidingo eziqinile kokuqukethwe kanye nefomethi yombiko wokuhlola, njenge:Kudinga umbiko wokuhlolwa ukuthi ufake ulwazi oluningiliziwe njengezindlela zokuhlola, izimo zokuhlola, imiphumela yokuhlolwa, kanye neziphetho.

Umbiko wokuhlolwa uyadingeka ukuthi ukhishwe yi-ejensi yokuhlola efanelekile. Isibonelo,I-DINSEN iqinisekiswe yi-CASTCO.
Izinga le-EN877:2021 libanzi kakhulu futhi liqinile ekuhlolweni kunezinga le-EN877:2006, elibonisa intuthuko yakamuva yezobuchwepheshe kanye nezidingo zemakethe embonini yamapayipi ensimbi ensimbi. Ukusetshenziswa kwezinga elisha kuzosiza ekuthuthukiseni ikhwalithi yemikhiqizo yamapayipi ensimbi ensimbi futhi kukhuthaze ukuphepha nokuthembeka kwezinhlelo zokudonsa amanzi ezakhiweni.
