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

Izinga le-EN877 licacisa izidingo zokusebenza zeamapayipi ensimbi, okokufakafuthiizixhumi zaboesetshenziswa ezinhlelweni zokukhipha amanzi adonsela phansi ezakhiweni.EN877:2021inguqulo yakamuva yezinga, ingena esikhundleni senguqulo yangaphambilini ye-EN877:2006. Umehluko omkhulu phakathi kwalezi zinguqulo ezimbili mayelana nokuhlolwa umi kanje:

1. Ububanzi bokuhlola:

I-TS EN 877:2006 Ihlola ikakhulukazi izakhiwo zemishini kanye nezakhiwo zokuvala zamapayipi nokufakwa.

I-TS EN 877: 2021: Ngokwesisekelo sokuhlolwa kwasekuqaleni, izidingo zokuhlola ezingeziwe zokusebenza kokufakwa komsindo, ukumelana nokugqwala kwamakhemikhali, ukumelana nomlilo nezinye izici zesistimu yamapayipi.

2. Izindlela zokuhlola:

I-EN 877:2021 ibuyekeza ezinye izindlela zokuhlola ukuze zizenze zesayensi futhi zibe nengqondo, njenge:Ukuhlolwa kokumelana nokugqwala kwamakhemikhali: Kusetshenziswa izixazululo ezintsha zokuhlola nezindlela zokuhlola, ezifana nokusebenzisa isixazululo se-pH2 sulfuric acid esikhundleni sesisombululo sokuqala se-hydrochloric acid, kanye nokwengeza izivivinyo zokumelana nokugqwala kwamakhemikhali engeziwe.

Ukuhlolwa kokusebenza kwe-Acoustic: Izidingo ezingeziwe zokuhlola ukusebenza kokufakwa komsindo wesistimu yepayipi, njengokusebenzisa indlela yezinga lokucindezela komsindo ukukala ukuvala umsindo kwesistimu yamapayipi.

Ukuhlolwa kokusebenza komlilo: Izidingo ezingeziwe zokuhlola ukusebenza kokumelana nomlilo kwesistimu yamapayipi, njengokusebenzisa indlela yomkhawulo wokumelana nomlilo ukuze kuhlolwe ubuqotho besistimu yamapayipi ngaphansi kwezimo zomlilo.I-EN 877:2021 isebenzisa upende onokumelana nomlilo ibanga A1

3. Izidingo zokuhlola:

I-EN 877:2021 inyuse izidingo zokuhlolwa kwezinye izinkomba zokusebenza, njenge:Amandla okuqina: akhuphuka ukusuka ku-150 MPa kuya ku-200 MPa.
Ukwandisa: kukhuphuke kusuka ku-1% kuya ku-2%.

Ukumelana nokugqwala kwamakhemikhali: Izidingo ezingeziwe zokumelana nokugqwala kwezinto zamakhemikhali engeziwe, njengezidingo zokumelana nokugqwala kwezinto ezine-alkali njenge-sodium hydroxide ne-potassium hydroxide.

4. Umbiko wokuhlola:

I-EN 877:2021 inezidingo eziqinile kokuqukethwe nefomethi yombiko wokuhlola, njenge:Idinga umbiko wokuhlola ukuthi uhlanganise imininingwane enemininingwane efana nezindlela zokuhlola, izimo zokuhlola, imiphumela yokuhlolwa, neziphetho.

Umbiko wokuhlola udingeka ukuthi ukhishwe i-ejensi yokuhlola eqeqeshiwe. Ngokwesibonelo,I-DINSEN iqinisekiswe yi-CASTCO.
Izinga le-EN877:2021 libanzi futhi liqinile ekuhlolweni kune-EN877:2006 ejwayelekile, libonisa intuthuko yakamuva yobuchwepheshe kanye nezidingo zemakethe embonini yamapayipi ensimbi. Ukuqaliswa kwaleli zinga elisha kuzosiza ukwenza ngcono izinga lemikhiqizo yamapayipi ensimbi futhi kukhuthaze ukuphepha nokwethembeka kwezinhlelo zokwakha zokudonsa amanzi.
