Amabhawudo

Ayikho ihloko, ukuxhumana okuzinzileko komthwalo onzima.

Amabhawudo we-Stud akhiqiziweko, ukuhluleka okukhululekileko.

Isiko lefekthri, lifanela zoke iinthombe ze-flange.

Ilanga Amabhawudo we-Stud – Ukubopha kwe-Flange eneentambo ezimbili ye-ASME B16.5 B7 / B8 / B16 & API Pressure Piping Systems

Siphakela amabhawudo we-stud (ama-double-end threaded rods / ama-flange studs aphelele) ku-Grede B7, B7M, B8, B8M & B16, anamantongomani afanako we-A194. Kusukela emaphayiphini we-oli negesi ukuya eembhoshongweni ze-petrochemical kanye nemikhumbi yokugandeleleka kwesitjalo samandla, i-stud bolt ngayinye ihlangabezana ne-ASME B16.5, i-ASTM A193, kanye ne-NACE MR0175. Bawa isitifiketi sesigayo esilandelelanako nge-oda lakho lokubopha i-flange enengi namhlanjesi.

I-Sinsun Stud Bolts | Ukuhlolisisa komkhiqizo & Iinzuzo eziqakathekileko

Thola ikhowuthi emsinyana

Amabhawudo we-stud, aziwa nangokuthi zii-stud ezine-thread nofana iintambo zokubophelela, zizinto zokubophelela zensimbi ezingenahloko ezifakwe nge-thread emphethweni owodwa nofana zombili. Iimakethe zebubulo zazi umkhiqizo lo ngamagama ahlukileko. Emafemini we-Europe, ibizwa ngokuthi ma-bolts anentambo ngaphandle kwe-tête; hlangana namaklayenti wamabubulo we-Spain, yaziwa nge-pernos roscados sin cabeza, begodu emibuthanweni yezobunjiniyela, yaziwa nange-flange stud bolts. Izikhonkwane ezingenahloko azifani namabholthi we-hex ajwayelekileko ngombana zidzimelele ekuhlanganisweni okufakwe ngaphakathi begodu zinikela ngokukhiya okunembileko kwemitjhini enomthwalo omkhulu kanye neenhlelo zokuhlanganisa amapayipi.

I-Sinsun, njengomkhiqizi we-stud bolt oyingcweti, yakha ukuncintisana komkhiqizo ohlukileko ngokusebenzisa ukufanisa izinto ezihlelekileko nokusebenza ngokunembileko. Abathengisi abanengi abajayelekileko banganikela ngeenkhonkwane eziqediweko ezinezinga elilodwa lokusebenza kwemitjhini ngezinga eliqinileko. Sihlukanisa ngokuqinileko izinto ezisetjenziswako kanye neenkambo zokutjhisa ngokuya ngezinga lokutjhisa eliphezulu, umfutho ophakemeko kanye nokuqina kokudlidliza. Boke amabhawudo wethu we-stud enziwa ngokuya ngamazinga we-ASTM, DIN kanye ne-API ukuqinisekisa ukunemba kwentambo okufanako nokuqina kwesakhiwo.

Abathengi bezobunjiniyela bephasi loke banobunzima obufana nokugandeleleka kwentambo, ukuguquguquka kwe-shank kanye nokujamelana nokudinwa okumbi okuvela emabhodini we-stud wekhwalithi ephasi. Imiraro yebubulo iphathwa ngokubunjwa okuhlangeneko ngokusika intambo yesibili. Amabhawudo wethu we-double end stud, amabhawudo we-thread aragela phambili kanye nama-tapping end stud bolts atjengisa ukusebenza okuqinileko kokuhlanganiswa ngaphasi komthwalo wesikhathi eside nokutjhuguluka okukhulu kwamazinga womtjhiso. Ngaphandle kwalokho, sibuye sinikele ngobukhulu obungekho emthethweni namandla wokwenza ngokwezifiso ukwanelisa iimfuno zephrojekthi yezebubulo.

Imihlobo yamabhawudo we-Stud | I-Sinsun Full Hot-Selling Classification

Phequlula yoke imihlobo yamabhawudo we-Sinsun, kufaka hlangana ama-double end, ama-tap end, intambo eragela phambili, amandla amakhulu kanye nama-stainless steel amabhawudo weensetjenziswa ezihlukahlukeneko zebubulo.

Amabhawudo we-Stud we-Double End

Amabhawudo we-Sinsun double end stud ngamaphethelo alinganako anentambo kanye ne-shank ephakathi ebutjhelelezi engakafakwa iintambo. I-shank ehlanganisiweko ingahlakaza ukugxila kokugandeleleka begodu yenze ngcono ukujamelana nokudinwa kwamacala womthwalo onamandla. Izikhonkwane lezi zenzelwe ukukhiya ama-nut wehlangothi ezimbili ukufikelela amandla wokubopha afanako wokuhlanganisa i-flange. Yimihlobo esetjenziswa khulu yokubophelela amaphayiphi we-flange kanye namaphrojekthi wokuhlanganisa ngemitjhini.

Umhlahlandlela wokufakwa nokukhetha i-Stud Bolt – Ukwenza kuhle

1.Ukukhetha ibanga elifaneleko le-Stud Bolt

Kunemibuzo emibili ekufuze iphendulwe ngaphambi kokukhetha ibholthi ye-stud: Ngiliphi izinga lokutjhisa lokusebenza? Ingabe indawo ine-esidi (i-H2S ikhona)?

Izinga lokutjhisa eliphezulu (kuya ku-450°C), elingamuncu: i-ASTM A193 iGreyidi B7 amantongomani + i-A194 Igreyidi 2H amantongomani.

Izinga lokutjhisa eliphezulu, isevisi emuncu (i-H2S ikhona): ASTM A193 Ibanga B7M + A194 Ibanga 2HM amantongomani (ubunzima bungadluli i-22 HRC).

Izinga lokutjhisa eliphasi (-40°C nangaphasi) / i-cryogenic: ASTM A320 Grade L7 nofana L7M (ihlolwe umthelela) + A194 Grade 4/7 amantongomani.

Izinga lokutjhisa eliphezulu khulu (ngaphezu kwama-450°C ukuya ku-593°C): ASTM A193 Ibanga B16 + A194 Ibanga 2H, amantongomani ama-4 nofana ama-7 (kuya ngezinga lokutjhisa).

Iindawo ezibolako / eziselwandle, amandla alinganiselwe: i-ASTM A193 B8 iKlasi 1 (SS 304) nofana i-B8M iKlasi 1 (SS 316) + i-A194 iKlasi 8/8M amantongomani.

Ukwakhiwa okujayelekileko / ukugandeleleka okuphasi: Iintonga ezineentambo, i-ASTM A307 iGreyidi A nofana B (insimbi ephasi).

2.Amaphutha neziyeleliso ziqakathekile

Akukafaneli usebenzise amabhawudo we-hex ajwayelekileko anama-ASME B16.5 flanges. Ngebanga lokunciphisa indawo yokuthwala, kuzokuba nokugandeleleka okungalinganiko kwe-gasket okuzokwenza bona kube nokuvuza nokwephulwa kwekhodi. Kuvunyelwe kwaphela amabhawudo we-hex amakhulu nofana amabhawudo we-stud.

Ungahlanganisi amagreyidi we-stud ne-nut. Isikhonkwane se-B7 kufanele sisetjenziswe ne-2H, ingasi nge-Greyidi 5 nofana ye-Greyidi 8. Iintambo zingasuswa nofana zihluleke msinyana nangabe igreyidi ingakalungi.

Ungaqinisi khulu ukudlula i-torque ebekiweko. I-torque eyeqileko ilimaza imicu ye-stud, yehlisa umthwalo we-clamp begodu yenza bona isibopho sibe buthakathaka unomphela.

Ungalokothi ufake amabhawudo womileko. Iinsetjenziswa zokubophelela ezingagqwali namkha ezine-coated zizokuthambekela khulu ekutheni zibe ne-galling, khulukhulu nangabe imicu yomile. Ukufundwa kwe-torque okungakalungi kuzokuvela nangabe imicu yomile.

Iintambo kufanele zihlolwe bona azilimalanga ngaphambi kokuthi zihlanganiswe. Intambo eyodwa elimeleko ingabhubhisa yoke i-flange joint. Akunamkhawulo wokuthi intambo elimeleko ingenza umonakalo ongakanani ekuhlanganeni kwe-flange.
