I-EN 10216 uchungechunge lwamazinga: Izindinganiso ze-EU zamabhayela, amashubhu entuthu namashubhu okushisa aphezulu

Eminyakeni yamuva nje, ngokuthuthuka kwezimboni, isidingo samapayipi ensimbi asezingeni eliphezulu siqhubekile nokwanda, ikakhulukazi emikhakheni yamabhayela, amashubhu entuthu, amashubhu okushisa aphezulu kanye namashubhu okushisa umoya. Ukuze kuqinisekiswe ukuphepha, ukuqina nokusebenza kwale mikhiqizo, i-EU yakhe uchungechunge lwe-EN 10216 lwamazinga ukuze ucacise izidingo kanye nokusetshenziswa kwamapayipi ensimbi. Lesi sihloko sizogxila ezindinganisweni ezimbili ezibalulekile ze-EU, i-EN 10216-1 ne-EN 10216-2, igxile ekusetshenzisweni kwayo, amamaki amapayipi ensimbi ayinhloko kanye nezinyathelo zokuphepha lapho uzisebenzisa.

Ukuhumusha okujwayelekile: EN 10216-1 kanye ne-EN 10216-2

I-EN 10216-1 kanye ne-EN 10216-2 amazinga e-EU okukhiqiza amapayipi ensimbi kanye nezidingo zekhwalithi, ikakhulukazi ezinhlotsheni ezahlukene zamapayipi ensimbi kanye nezimo zokusebenzisa kwawo. I-TS EN 10216-1 ikakhulukazi ibandakanya izidingo zokwenziwa kwamapayipi ensimbi angenamthungo, ikakhulukazi ezinhlelweni ezinjengamabhoyela anomfutho ophezulu kanye namapayipi okudlulisa ukushisa angaphansi kwezimo zokushisa eziphezulu nezimo zengcindezi ephezulu. I-TS EN 10216-2 igxile emapayipini ensimbi athile e-alloy, njengalawo asetshenziswa kakhulu ezimbonini zamakhemikhali namandla. Lezi zindinganiso zicacisa ukwakheka kwamakhemikhali, izakhiwo zemishini, ukubekezelelana kwe-dimensional kanye nezinto zokuhlola ezidingekayo zamapayipi ensimbi ukuze kuqinisekiswe ukwethembeka nokuphepha kwamapayipi ensimbi akhiqizwayo ezindaweni ezinokhahlo ezifana nokushisa okuphezulu nokucindezela okukhulu.

Ukusetshenziswa okuyinhloko

Amapayipi ensimbi akhiqizwa ngokwezindinganiso zochungechunge lwe-EN 10216 asetshenziswa kakhulu kumapayipi amanzi abhayela, amapayipi entuthu, amapayipi okushisa aphezulu, amapayipi okushisa komoya nezinye izinkambu. Lawa mapayipi ensimbi ajwayele ukusetshenziselwa ukumelana nezinga lokushisa eliphezulu, amagesi agqwalayo kanye nezindawo zokusebenza zesitimu ezinomfutho ophezulu. Ngakho-ke, badinga amandla aphezulu, ukumelana nokugqwala okuhle kakhulu kanye ne-conductivity enhle yokushisa.

Kumshini wokubilisa, amapayipi ensimbi e-EN 10216 asetshenziselwa amapayipi amanzi okubhayela namapayipi entuthu ukuqhuba ukushisa nokukhipha igesi ephumayo. Amapayipi we-Superheater kanye namapayipi okushisa umoya nawo ayizindawo ezibalulekile zokufaka isicelo zalolu chungechunge lwamapayipi ensimbi. Indima yabo ukuthuthukisa ngokuphumelelayo ukusebenza kahle kokushisa kwama-boilers nokunciphisa ukusetshenziswa kwamandla.

Amabanga amapayipi ensimbi ajwayelekile

Ochungechungeni lwamazinga we-EN 10216, amabanga ajwayelekile wamapayipi ensimbi afaka:P195, P235, P265, P195GH, P235GH, P265GH, 13CrMo4-5, 10CrMo9-10, njll.. Lawa mabanga amapayipi ensimbi anezinhlobo ezahlukene zamakhemikhali nezinto ezibonakalayo futhi afanele izindawo zokusebenza ezihlukene. Isibonelo, amapayipi ensimbi e-P195GH kanye ne-P235GH avame ukusetshenziswa kumshini wokubilisa, kuyilapho i-13CrMo4-5 kanye ne-10CrMo9-10 isetshenziswa kakhulu ezintweni zamakhemikhali kanye nezinga lokushisa eliphezulu kanye nezindawo zokucindezela okukhulu.

Izinyathelo zokuphepha zokusetshenziswa

Yize amapayipi ensimbi e-EN 10216 esebenza kahle kakhulu, ezinye izinyathelo zokuphepha kusafanele zithathwe uma uwasebenzisa. Okokuqala, abasebenzisi kufanele bakhethe ibanga elifanele lepayipi lensimbi ngokwendawo ethile yohlelo lokusebenza ukuze baqinisekise ukusebenza okuphephile kwesistimu yamapayipi. Okwesibili, ipayipi yensimbi idinga ukuhlolwa njalo ngesikhathi sokusetshenziswa, ikakhulukazi ezindaweni ezishisayo nezicindezelayo, futhi kufanele kuqashelwe ukuthi ipayipi inokugqwala, imifantu noma omunye umonakalo. Okokugcina, ukuze kwandiswe impilo yesevisi yepayipi yensimbi, ukuhlanza nokugcinwa njalo akufanele kunganakwa.

Uchungechunge lwe-EN 10216-1 kanye ne-EN 10216-2 lwamazinga luhlinzeka ngemikhiqizo yepayipi yensimbi yekhwalithi ephezulu yokukhiqizwa kwezimboni, iqinisekisa ukuphepha nokuzinza kwezinto ezisetshenziswayo ezibalulekile njengamabhayela, amapayipi omusi, amashubhu okushisa okuphezulu, njll. Ngokulandela la mazinga, ukusebenza kahle kwezisetshenziswa kungakhuliswa futhi ukusebenza okuqhubekayo nokuzinzile kokukhiqizwa kwezimboni kungaqinisekisa.
