Do you know which types of flanges are included in BS4504?

Ukusebenzisa i-BS4504 ejwayelekile, kukhonaipuletiama-flange, weld neck flanges, slip kuma-flanges, i-flange enentambo futhii-flange eyimpumputhe, njll. Mayelana nalezi zinhlobo zama-flange, zizokwethula ukucindezela kosayizi othize kanye neminye imininingwane I-Plate Flanges (Code101)

I-Plate type flat welding flange (i-chemical standard HG20592, i-GB/T9119 ejwayelekile kazwelonke, i-JB/T81 yomshini): ukutholakala kalula kwezinto zokwakha, ukwenziwa lula, izindleko eziphansi nokusetshenziswa okubanzi.Kodwa-ke, ukuqina kwayo kubi kakhulu, ngakho-ke ayikwazi ukusetshenziselwa ukuhlinzeka nokufunwa, amasistimu amapayipi enqubo yamakhemikhali avuthayo kanye neziqhumane.Lezi zinhlelo zidinga ukuqhuma kanye ne-vacuum ephakeme, futhi ziyingozi kakhulu.Uhlobo lwendawo yokuvala luyisicaba futhi luyi-convex.

I-flange enentambo iyi-flange engashiselwe, exhunywe epayipini elinentambo ngokucubungula imbobo engaphakathi ye-flange ibe intambo yepayipi.Uma kuqhathaniswa ne-flange ye-welding eyisicaba noma i-butt welding flange, i-flange ene-threaded inezici zokufaka nokugcinwa okulula, futhi ingasetshenziselwa amapayipi angavumeli ukushisela insimu.I-alloy steel flange inamandla anele, kodwa akulula ukushisela, noma ukusebenza kwe-welding akukuhle, i-flange ene-threaded nayo ingakhethwa.Kodwa-ke, lapho izinga lokushisa lepayipi lishintsha ngokushesha noma izinga lokushisa lingaphezulu kuka-260 ° C kodwa lingaphansi kuka-45 ° C, kutuswa ukuthi ungasebenzisi i-flange enentambo ukugwema ukuvuza.

Isembozo se-flange sibizwa nangokuthi i-blind flange, ipuleti eliyimpumputhe.Lena i-flange engenambobo phakathi, esetshenziselwa ukuvala ipulaki yepayipi.Lo msebenzi uyafana nalowo wekepisi yepayipi ehlanganisiwe neluchungechunge.Umehluko wukuthi i-flange eyimpumputhe kanye ne-threaded pipe cap ingasuswa nganoma yisiphi isikhathi, kodwa ikhanda le-welding alikwazi ukususwa.Kunezinhlobo eziningi zezindawo zokuvala, ezihlanganisa indawo eyisicaba, i-convex, i-concave ne-convex, indawo ye-tenon ne-groove kanye nezindawo zokuxhuma ze-annular.

Ama-flange ajwayelekile aseMelika ayizingxenye ezixhuma amapayipi namapayipi neziphetho zamapayipi.Ama-flange ajwayelekile e-butt-welded aseMelika ayakhiwa futhi afakwe ngezindlela ezimbili.I-American standard butt welding flange ingahlukaniswa ibe yi-American standard butt welding flange ne-non-necked American butt welding flange ngokwemibandela yentamo yayo.I-American butt welding flange ihlanganisa amapuleti amabili e-flange kanye nama-flange gaskets.Amawasha e-Flange aboshwe ndawonye ukuze aqedele uxhumano.I-American flange ejwayelekile inezimbobo, futhi amabhawodi axhuma ama-flange amabili ngokuqinile.I-flange ivalwe nge-gasket.
