I-TS EN 1092-1 Welding Neck Flange Stainless Steel Carbon steel

Idatha Yomkhiqizo

Isingeniso Somkhiqizo

Izinga le-EN1092-1 lingelinye lamazinga aklanywe ngokuhlanganyela yi-European International Organisation for Standardization (ISO) kanye ne-European Organisation for Standardization (CEN), ecacisa ukwakheka, usayizi kanye nezidingo zobuchwepheshe zama-flange nezisekeli ze-flange.Phakathi kwazo, i-neck butt welding flange ingenye yezinhlobo ezivamile ze-flange.

I-weld neck flange iyindilingai-flangeenentamo ephumele phakathi nendawo.Intamo iyingxenye esetshenziselwa ukuxhuma i-flange kanye nepayipi noma imishini, futhi i-flange igxilwe kwipayipi noma imishini ngokushisela intamo.I-Weld neck flanges ngokuvamile yenziwe nge-carbon steel, insimbi engagqwali noma i-alloy steel futhi ifanele ukucindezela okuphezulu kanye nezicelo zokushisa okuphezulu.

Izinga le-EN1092-1 libeka usayizi nezinga lokucindezela kwe-flange yentamo eshiselwe ukuqinisekisa ukuthi ukuxhumana kwayo nepayipi noma okokusebenza kungenziwa ngaphansi kwezimo eziphephile nezithembekile.Izinga liphinde lihlanganise nezidingo zempahla, ukukhiqiza kanye nokuhlola ama-flange ukuze kuqinisekiswe ukuhambisana nekhwalithi efanele kanye namazinga okuphepha.

Weld intamo flangekuyindlela evamile yokuxhuma i-flange, esetshenziswa kabanzi emkhakheni wezimboni.Ukuklanywa nokukhiqizwa kwayo kudinga ukulandela izindinganiso ezifanele kanye nokucaciswa kwayo ukuze kuqinisekiswe ukusebenza kwayo okuhle nokwethembeka.

Usayizi:
Osayizi abajwayelekile be-weld neck flange bayahlukahlukakusuka ku-DN15 kuya ku-DN2000.

Ingcindezi:
Izilinganiso zokucindezela ezijwayelekile ze-weld neck flange ziyahlukahlukakusuka ku-PN2.5 kuya ku-PN100.

Ngaphezu kwalokho, izinga le-EN1092-1 liphinde libeke izidingo zobuchwepheshe ezifana nosayizi wembobo yebhawodi, ubuningi, kanye ne-pitch ye-flange yentamo eshiselwe ukuqinisekisa ukuthi ukuxhumana kwayo nepayipi noma okokusebenza kungenziwa ngaphansi kwezimo eziphephile nezithembekile.

Kodwa-ke, kufanele kuqashelwe ukuthi amazwe ahlukene kanye nezifunda zingase zibe nezindinganiso zazo kanye nokucaciswa kwazo, ngakho-ke lapho ukhetha ama-flange welding we-neck butt, kufanele futhi ubhekisele kumazinga ahambisanayo kanye nokucaciswa ngokuvumelana nesimo esithile.

Inzuzo:
1.I-neck butt welding flange inomsebenzi omuhle wokuvala futhi ingasetshenziselwa ukuxhuma amapayipi anomfutho ophezulu, izinga lokushisa eliphezulu noma imidiya ebolayo.
2.Ngenxa yokuba khona kwentamo, i-neck butt welding flange ingakwazi ukumelana nemithwalo emikhulu kanye nemithwalo yethonya, futhi inokumelana nokushaqeka okungcono.
I-3.I-weld neck flange inesakhiwo esihlangene futhi ayinaso izinkinga zokuvuza.
I-4.I-neck butt welding flange inendlela elula yokuxhuma futhi kulula ukuyifaka nokuhlakaza.

Ububi:
I-1.Izindleko zokukhiqiza ze-weld neck flange ziphakeme kakhulu.
2.Njengoba ukuklanywa nokukhiqizwa kwayo kudinga ukulandela ngokuqinile izindinganiso nezinkambiso, kunenkinga yokulawulwa kwekhwalithi enzima kakhulu ekukhiqizeni nasekusetshenzisweni.

Izicelo:
I-Welding neck flange ifanele ukuxhunywa kwamapayipiemikhakheni eminingi, ikakhulukazi lezo ezidinga umfutho ophezulu, izinga lokushisa eliphezulu, ukugqwala, ukudlidliza nezinye izimo zokusebenza.Izindawo ezithile ezisetshenziswayo zihlanganisa uphethiloli, amakhemikhali, amandla kagesi, igesi yemvelo, ezamakhemisi, ezokudla, zephepha nezinye izimboni.

Ngamafuphi, i-neck butt welding flange iyindlela ethembekile yokuxhuma ipayipi esebenza kahle ngokuvala kanye nokumelana nokushaqeka.Ifanele ukuxhunywa kwamapayipi okunengcindezi ephezulu, izinga lokushisa eliphezulu, nokugqwala okumaphakathi.Lawula ikhwalithi.
