I-Alloy Steel Fasteners

I-ASTM A320 I-Grade L7 ingukucaciswa kwezinto ezibonakalayo zama-bolts, ama-stud, amantongomane, namanye ama-fasteners enzelwe izinhlelo zokusebenza zokushisa okushisa okuphezulu. Ama-ASTM A320 L7 amamaki ahlukaniswe amakilasi okusebenza angu-4, a, B, C, no-D, ngamunye anezakhiwo ezihlukile ze-Tensile nengcindezi. Ama-fasteners angama-660 asetshenziselwa ukubopha ama-bolter, imithambo yengcindezi, ama-flange amaphayipha kanye nama-valves wenkonzo yokushisa ephezulu.

Ukwelashwa kwesixazululo se-Carbide, esaziwa nangokuthi isixazululo se-annelling, inqubo lapho ama-fasteners noma izinduku zensimbi ezingenasici ziyafudumala bese kucishwa amanzi ukuze kuqinisekiswe ukumelana nokugqwala okukhulu. I-A193 Ibanga le-B8 Ibanga 2 Amabhulokhethi anzima ukwelashwa ngemuva kokwelashwa kwesisombululo se-Carbide ukuthuthukisa izinsiza zamandla futhi anciphise amandla okugqoka.

Ukucaciswa kwe-ASTM A320 Ibanga le-L7M izinto ezihlanganisa insimbi yensimbi kanye nezinto zokubopha insimbi ezingenasici zezicelo zokushisa eziphansi. Izikopelo ze-ASTM A320 L7 zingasetshenziswa futhi kuzinhlelo zokusebenza ezinamazinga okushisa akhona aze afike ku -150of. I-ASTM A320 Ibanga L7m Bolts kanye ne-ASTM A320 Bolts inenani elincane eliphansi le-charpy lamakhilogremu ayi-15 kulokhu okushisa.

I-ASTM A193 Ibanga le-B8M grade 1 liyafana nebanga le-B8 kodwa lenziwa ngensimbi engagqwali esikhundleni se-Aisi 304 insimbi engagqwali. Uhlobo lwensimbi engama-316 olungenasici lunokumelana okungcono kokugqwala kunendlela yohlobo 304 insimbi engagqwali ngenxa yokungezwa kwe-molybdenum.

I-ASTM A193 Ibanga le-B7 Ukucaciswa Ihlanganisa izidingo zamandla aphezulu wensimbi yensimbi yokuphumula yokushisa okuphezulu noma insizakalo ephezulu yengcindezelo nezinye izinhlelo ezikhethekile zenhloso. Kungukucaciswa okujwayelekile okuchaza ukwakheka okujwayelekile kwamakhemikhali, izakhiwo zemishini, izidingo zobulukhuni, ukwelashwa okungcono kakhulu, ukumakwa komkhiqizo, nezitifiketi, nezinye izidingo zokuxhunyaniswa kokuxhunyaniswa okusetshenziselwa insiza yomkhumbi, ama-valves, amavutha, kanye nokufakelwa. I-ASTM A193 ichaza i-SI (metric) namayunithi we-inch-pound.

I-ASTM A194 Ukucaciswa ihlanganisa izinhlobo eziningi zekhabhoni, i-alloy, namantongomane ensimbi engagqwali emalungeni asukela ku-1 \ 4 kuya ku-4 inches kanye ne-metric m6 ku-M100. Ibuye ihlanganise amantongomane ensimbi engagqwali ngobubanzi bezinhlobo ze-1 \ 4 intshi kanye ne-M6. Lawa mantongomane asetshenziselwa ingcindezi ephezulu noma insizakalo yokushisa ephezulu, noma zombili.

I-ASTM A194 2H obonke osebenzayo we-hex bolts ngumkhiqizo oyisisekelo futhi asesitokweni. I-HT Pipe ingumhlinzeki oholayo we-ASTM A194 2H oyisindayo we-Hex Nuts. Lokhu kudla okusindayo kwe-hex nut nati hlobo njengoba kuqondiswe yi-ASTM A-193 Procation.

Ama-B7 Threaded Studs kanye nama-BOLTS amafushane atholakala kalula emakethe. Ama-B7 Ibanga lama-bolts ajwayele ukusetshenziselwa ukuxhumana kwe-flange reape. Lezi zimbotshana zivame ukuthengiswa endaweni evamile yensimbi engenalutho, kepha zivame ukuxubanisa-cxuted, i-galvanized, i-xylan ehlanganisiwe, i-ptfe ehlanganiswe, noma iphathwe ngenye indlela ngenhlanganisela yokumelana nokugqwala.

Amantongomane anosayizi ongokwesiko ngaphezulu kwe-intshi engu-Intshi kufanele abe yisigaba se-UNC Series Class 2B Fit noma i-8 Un class 2B kufanelekile. Amandla aphezulu we-ASTM A194 Ibanga 2h amantongomane ajwayelekile emakethe futhi avame ukushintshwa yi-ASTM A563 Ibanga le-DH NTH ngenxa yokutholakala okulinganiselwe kwama-DH NUTS kumadayimane athile nama-purts.

I-ASTM A193 Ibanga le-B8 ibanga le-1 ama-bolts kanye nama-stud enziwe ngensimbi engenasici aisi 304. Thayipha i-304 yibanga lensimbi elisetshenziswa kakhulu embonini ye-fastener.

Ama-Fasteners enziwe kule nsimbi ye-auntenitic engagqwali adinga ukwelashwa kwesixazululo kwe-carbide kwebha, noma ukwelashwa kwesixazululo se-carbide ngemuva kokusebenza kwekhanda ngamakhanda anekhanda.

I-ASTM A194 Ukucaciswa kuhlanganisa ikhabhoni, ama-alloy kanye namantongomane ensimbi angenasici engcindezi ephezulu kanye ne-\ noma insiza yokushisa ephezulu. I-American National Standard Duty Hex Series (ANSI B 18.2.2) izosetshenziswa ngaphandle kokuthi ichazwe ngenye indlela. Amantongomane angabi ngaphezu kwe-1 intshi ngosayizi ogama azohambisana no-Un Series Class 2B.

A193 B7, A194 2H, A320 L7, I-ASME B188.2.1 Hex Bolts Asme B18.22.1, I-Hex Bolt, U-U-Bolt, Hex Socket Cap Screw, Hex I-Nut, i-washer ethambile, i-washer yasentwasahlobo. on - zhengzhou Huitong Pipeline Equipment Co, Ltd.

I-ASTM A320 L7 Stud Bolts yenzelwe ukusebenza okuphansi kokushisa. Lawa ma-fasteners ajwayele ukusetshenziswa kuma-valves, ama-flanges, ukufakwa kanye nemikhumbi yengcindezi. Ukucaciswa kwe-ASTM kuncoma inani eliphansi lomthelela le-20-FT-LBF -150f ye-ASTM A320 L7 Izikopelo.

Ama-fasteners we-B8M adinga ukwelashwa kwesisombululo se-carbide, ngenkathi ama-fasteners webanga 2 adinga imisebenzi eyengeziwe yokuqina kanzima ukwandisa amandla futhi wehlise ukuthambekela.
