ANSI ASME B16.9 iNsimbi eNgatyiwayo eWelded ingqiniba engenamthungo ye-45 Degree

Ukunikezelwa kweMveliso

Kwinkqubo yemibhobho, iingqinibayinto efanelekileyo etshintsha indlela yokubaleka. Uhlobo lokudibanisa umbhobho wokulinganisa oqhelekileyo osetyenziswa kufakelo lwemibhobho, ukudibanisa imibhobho emibini kunye nedayamitha elinganayo okanye eyahlukileyo ukwenza umbhobho ujike kwi-engile ethile, kunye noxinzelelo lwegama yi-1-1.6Mpa.

Ii-engile eziqhelekileyo ziyi-45 ° kunye ne-90 ° 180 °. Ukongeza, kukho i-60 ° kunye nezinye ii-angle elbows ezingaqhelekanga ezifunwa yiprojekthi.

Izinto zengqiniba ziquka intsimbi etyhidiweyo,yenziwe ngentsimbi eshayinayo, intsimbi yealloyi, intsimbi ekhatywayo enokunyibilika, intsimbi yekhabhoni, isinyithi esingenaferrous kunye neeplastiki.

Iindlela zokudibanisa eziqhelekileyo kunye nemibhobho ziquka i-welding ngokuthe ngqo, i-flange uxhumano, uxhulumaniso olutshisayo lwe-melt, uxhumano lwe-melt melt, uxhumano lwentambo kunye nokudibanisa i-socket.

Ukusetyenziswa kwe-elbow yensimbi engenasici

I-elbow yensimbi engenasici ngenjongo eqhelekileyo igqitywe yintsimbi eqhelekileyo ye-carbon structural, i-alloy low structural steel okanye i-alloy structural steel, kunye nemveliso enkulu, kwaye isetyenziswa ikakhulu njengombhobho okanye inxalenye yesakhiwo sokuthutha ulwelo.

Izilumkiso zokusetyenziswa kwe-elbow yensimbi engenasici

I-1.Ngexesha lofakelo, i-elbow yensimbi engenasici ingafakwa ngokuthe ngqo kumbhobho ngokwendlela yokudibanisa, okanye inokufakwa ngokwendawo yokusetyenziswa. Kwiimeko eziqhelekileyo, inokufakwa naphi na kumbhobho, kodwa kufuneka ivalwe ukuze ithintele ukuvuza okugungxulwayo kunye nokuchaphazela ukusebenza okuqhelekileyo kombhobho.
2.Xa i-valve yebhola, i-valve yeglobhu kunye ne-valve yesango ene-elbow yensimbi engenasici isetyenzisiweyo, inokuvulwa ngokupheleleyo okanye ivalwe. Azivumelekanga ukuba zisetyenziswe kulawulo lokuhamba ukuphepha ukutywinwa.
3.Ukugcinwa kwexesha elide le-elbow yensimbi engenasici, ukuhlolwa rhoqo kuya kwenziwa. Imiphezulu evezwa ngoomatshini iya kugcinwa icocekile, ukungcola kuya kususwa kwaye kugcinwe ngokucocekileyo kwindawo engena umoya neyomileyo ngaphakathi. Akuvumelekanga ngokungqongqo ukupakisha kunye nokugcina kwindawo evulekile. Ngalo lonke ixesha gcina ingqiniba yentsimbi yomile kwaye ingena umoya, gcina isigcini sicocekile kwaye sicocekile, kwaye usigcine ngokwendlela echanekileyo yokugcina.

Intsimi yesicelo se-elbow yensimbi engenasici

Ingqiniba yentsimbi isetyenziswa kakhulu kwipetroleum, kwishishini lekhemikhali, kwiplanti yamandla enyukliya, kwimveliso yokutya, ekwakhiweni, ekwakhiweni kweenqanawa, kukwenziwa kwephepha, kumayeza nakwamanye amashishini. Inosetyenziso olwahlukileyo kumashishini ahlukeneyo kwaye ibonisa ixabiso layo lokusetyenziswa kumashishini ahlukeneyo.

Umahluko phakathi kwengqiniba yentsimbi engenastainless kunye ne-carbon steel elbow

Umahluko omkhulu phakathi kwe-elbow yensimbi engenasici kunye ne-carbon steel elbow yinto. Ukubunjwa kwayo kweekhemikhali kuya kugcina i-elbow surface kwi-rust kunye ne-corrosion ixesha elide. Inokuguqulwa ibe:
1. Iindlela zokuvelisa: ukutyhala, ukucinezela, ukubunjwa, ukuphosa, njl.
2. Imigangatho yokuvelisa: umgangatho wesizwe, umgangatho weenqanawa, umgangatho wombane, umgangatho wamanzi, umgangatho waseMelika, umgangatho waseJamani, umgangatho waseJapan, umgangatho waseRashiya, njl.

Ixabiso loxinzelelo

Sch5s,Sch10s,Sch10,Sch20,Sch30,Sch40,STD,Sch40,Sch60、Sch80s、XS; Sch80、SCH100、Sch120、Sch140、Sch160、XXS;

Ezona zisetyenziswa kakhulu zi-STD kunye ne-XS.

Idatha yoMda

Imibandela Efuna Ingqalelo

I-1.Ngexesha lofakelo, i-elbow yensimbi engenasici ingafakwa ngokuthe ngqo kwipayipi ngokwendlela yokudibanisa kwaye ifakwe ngokwendawo yokusetyenziswa. Ngokuqhelekileyo, inokufakwa kuyo nayiphi na indawo yombhobho, kodwa idinga ukutywinwa ukukhusela ukuvuza kunye nokuchaphazela ukusebenza okuqhelekileyo kombhobho.

2. Xa usebenzisa i-stainless steel elbow ball valves, i-globe valves kunye ne-gate valves, zisetyenziselwa kuphela ukuvula ngokupheleleyo okanye ukuvala ngokupheleleyo. Abavumelekanga ukuba basetyenziselwe ukulungiswa kokuhamba ukuphepha ukutywinwa.

3.I-elbow yensimbi engenasici egcinwe ixesha elide iya kuhlolwa kwishedyuli. Umphezulu ovelileyo wokulungisa kufuneka uhlale ucocekile, kwaye ukungcola kuya kususwa. Iya kugcinwa ngokucocekileyo kwindawo engenamoya neyomileyo ngaphakathi. Ukupakisha okanye ukugcinwa kwangaphandle akuvumelekanga ngokungqongqo. Ngalo lonke ixesha gcina ingqiniba yentsimbi yomile kwaye ingena umoya, gcina isigcini sicocekile kwaye sicocekile, kwaye usigcine ngokwendlela echanekileyo yokugcina.

Iingcebiso: Zininzi izinto ekufuneka uzithathele ingqalelo xa kusetyenziswa iingqiniba zentsimbi engatyiwayo. Abasebenzisi bafanele bazisebenzise ngendlela ethile, kwaye bazisebenzise kwaye bazigcine ngendlela echanekileyo nesengqiqweni.
