Uhlolojikelele Lomkhiqizo Izikulufu zokuzibhoboza zokuzihlomisa ezinomhloko oyisicwebeza esinamapulangwe e-hex ezenziwe nge-stainless steel 304 (ezaziwa nangokuthi izikulufu ze-Tek ze-stainless steel A2 noma izikulufu zophahla ezizibhobozayo) ziyizinto zokubopha zekhwalithi ephezulu, ezimelana nokugqwala eziklanyelwe ukubopha amashidi ophahla lensimbi, izingubo zensimbi, nezakhiwo zensimbi ezingasindi ezisekelweni zensimbi noma zokhuni ezindaweni ezinzima kakhulu. Umhloko oyisicwebeza esinamapulangwe e-hex unikeza indawo enkulu yokuthwala futhi ushaywa nge-hex socket ejwayelekile, kuyilapho i-EPDM-bonded sealing washer ehlanganisiwe idala ukuvalwa okungangenisi amanzi eduze komgodi obhoboziwe. Ngokungafani nezinye izinto zokubopha zensimbi ye-carbon, lezi zikulufu zenziwa nge-AISI 304 (A2) austenitic stainless steel — izinga lomkhakha lokumelana nokugqwala ezindaweni ezisogwini, olwandle, nasemazingeni aphezulu omswakama. Izinga le-stainless steel 304 linikeza ukumelana okuhle kakhulu nokugqwala nokugqwala ezindaweni ezinzima, okwenza lezi zikulufu zilungele amaphrojekthi asogwini lwaseMpumalanga Ephakathi, ukufakwa olwandle, kanye nengqalasizinda yangaphandle yase-Asia Ephakathi lapho izinto zokubopha zensimbi ye-carbon zingahluleka ngokushesha. Lezi zikulufu zenziwa ngokwe-DIN 7504 K (isikulufu esizibhobozayo esinomhloko oyisicwebeza esinamapulangwe e-hex) kanye namazinga e-ISO 15480. Iphoyinti elizibhobozayo (i-Tek point) lisusa isidingo sokubhoboza kuqala — isikulufu sizibhobozela umgodi waso wokuhola emashidini ensimbi afinyelela ku-12.5 mm ubukhulu, bese sakha intambo ehambisanayo esisekelweni. Kuyatholakala ngobubanzi be-ST4.2, ST4.8, ST5.5, ne-ST6.3 mm, ngobude obusuka ku-13 mm kuya ku-150 mm. Ukwakhiwa kwe-stainless steel 304 kunikeza ukumelana nokugqwala okuphezulu uma kuqhathaniswa nezikulufu zensimbi ye-carbon ezigcotshwe nge-zinc noma ezigcotshwe nge-hot-dip galvanized. Izikulufu ze-304 ziphasa ukuhlolwa kwe-neutral salt-spray (ASTM B117) okungaphezu kuka-≥720 amahora, zinikeza isikhathi sokusebenza esiphindwe izikhathi ezi-3–5 kunalezo zezikulufu ezijwayelekile zensimbi ye-carbon. Lokhu kuzenza zibe ukukhetha okuthandwayo kophahla lwensimbi, izingubo zodonga, amapayipi e-HVAC, ukufakwa kwamaphaneli elanga, nezinhlelo zolwandle lapho ukuqina kwesikhathi eside kubalulekile. Izinga Nokuhambisana Ipharamitha Incazelo Izinga DIN 7504 K (isikulufu esizibhobozayo esinomhloko oyisicwebeza esinamapulangwe e-hex); ISO 15480; ASME B18.6.4 Impahla AISI 304 (A2) austenitic stainless steel Amandla Okudonsa 500–600 MPa (A2-70) Uhlobo Lwentambo Intambo ezibhobozayo (ST), Uhlobo 17 iphoyinti Uhlobo Lwekhanda Ikhanda eliyisicwebeza esinamapulangwe e-hex eline-EPDM sealing washer ehlanganisiwe Ukuqedwa Okucwebezelisiwe / okwenziwe i-passivated (i-stainless yemvelo) Ukumelana Nokugqwala ≥720 amahora e-neutral salt-spray (ASTM B117) I-Sealing Washer I-EPDM bonded washer (emelana ne-UV, izinga lokushisa −40 °C kuya ku-+120 °C) Izinga Lokushisa −40 °C kuya ku-+120 °C (washer); −200 °C kuya ku-+400 °C (umzimba wesikulufu) Amandla Okubhoboza Kufika ku-12.5 mm ipuleti lensimbi (kuncike kububanzi besikulufu) Ubukhulu Nemininingwane Usayizi Wesikulufu Ububanzi (mm) Ubude Obujwayelekile (mm) I-Hex Drive Ukusetshenziswa ST4.2 4.2 13 / 16 / 19 / 25 / 32 7 mm Uphahla olulula, izingubo ST4.8 4.8 19 / 25 / 32 / 38 / 50 / 65 8 mm Uphahla olujwayelekile, HVAC ST5.5 5.5 25 / 32 / 38 / 50 / 65 / 75 8 mm Uphahla olusindayo, izingubo zensimbi ST6.3 6.3 25 / 32 / 38 / 50 / 65 / 75 / 100 / 125 / 150 8 mm / 10 mm Uphahla olusindayo kakhulu, ukuxhumana kwesakhiwo Ubude nobubanzi obenziwe ngokwezifiso kuyatholakala uma kuceliwe. Izici Zomkhiqizo Ukwakhiwa Nge-AISI 304 (A2) Stainless Steel — Kunikeza ukumelana nokugqwala okuhle kakhulu ezindaweni ezisogwini, olwandle, nasemazingeni aphezulu omswakama. Kuphasa ukuhlolwa kwe-neutral salt-spray (ASTM B117) okungaphezu kuka-≥720 amahora futhi kunikeza isikhathi sokusebenza esiphindwe izikhathi ezi-3–5 kunalezo zensimbi ye-carbon. Iphoyinti Elizibhobozayo (i-Tek Point) — Iphoyinti lokubhoboza eliqinisiwe lingena emashidini ensimbi afinyelela ku-12.5 mm ubukhulu ngaphandle kokubhoboza kuqala, kunciphisa isikhathi sokufaka nezindleko zabasebenzi. Ikhanda Elisicwebeza Esinamapulangwe e-Hex — Indawo enkulu yokuthwala isabalalisa amandla okubopha ngokulinganayo futhi ivimbele ukulimala kwamashidi ophahla. Ihambisana nama-hex socket drivers ajwayelekile. I-EPDM-Bonded Sealing Washer — I-EPDM washer emelana ne-UV icindezelwa ngokumelene neshidi lophahla ukuze idale ukuvalwa okungangenisi amanzi, ivimbele ukungena kwamanzi endaweni yokungena kwesikulufu. Amandla Aphezulu Okubamba — Ukuqina okuphezulu namandla okubamba kuvimba ukukhululeka ngokuhamba kwesikhathi, ngisho nangaphansi kokudlidliza nokushintsha kwezinga lokushisa. Ububanzi Obukhulu Bosayizi — Ububanzi busuka ku-ST4.2 kuya ku-ST6.3 mm, ubude busuka ku-13 mm kuya ku-150 mm, kuhlanganisa cishe zonke izidingo zophahla, izingubo, nokubopha olwandle. Ukuqedwa Okuhambisana Nemvelo — Ukuqedwa kwe-stainless yemvelo kususa isidingo se-zinc plating noma ama-coatings, kugwema ukukhathazeka nge-hexavalent chromium futhi kusekela izinhloso zokusimama kumaphrojekthi okwakha aseMpumalanga Ephakathi. Izinhlelo Zokusetshenziswa Izikulufu zokuzibhoboza zokuzihlomisa ezinomhloko oyisicwebeza esinamapulangwe e-hex ezenziwe nge-stainless steel 304 zisetshenziswa kabanzi ku: Ukufakwa Kophahla Lwensimbi — Ukubopha amashidi ophahla ensimbi e-corrugated ne-trapezoidal kuma-purlins, ama-rafters, namafreyimu ensimbi ezindaweni ezisogwini nasemazingeni aphezulu omswakama. Izingubo Zodonga — Ukunamathisela amaphaneli odonga ensimbi, amaphaneli e-sandwich, ne-composite cladding ezakhiweni zensimbi noma zokhuni. Olwandle Nangaphandle Kwasolwandle — Ukubopha idethi, izakhiwo zamadokodo, nezinhlelo zezinkundla zasolwandle lapho ukugqwala kwamanzi anosawoti kuyinkinga. Ukufakwa Kwamaphaneli Elanga — Ukubopha ama-mounting rails nama-brackets ezakhiweni zophahla ezinhlelweni zamandla elanga. Amapayipi e-HVAC — Ukuqinisa i-insulation yamapayipi, ama-hangers, ne-flashing ezakhiweni zezentengiselwano nezimboni. Izindawo Zoyela Negesi — Ukubopha okumelana nokugqwala ezitshalweni ze-petrochemical nengqalasizinda yokucwenga uwoyela. Izakhiwo Zezolimo — Izindlu zezinkukhu, izibaya, nezindawo zokugcina lapho umswakama nokuchayeka kwe-ammonia kudinga ukumelana nokugqwala okuphezulu. Imihlahlandlela Yokufaka Khetha ubude besikulufu obulungile — Isikulufu kufanele singene esisekelweni okungenani nge-25 mm ngaphezu kobukhulu obuphelele bempahla eboshwayo. Sebenzisa isikrudrayiva esinejubane eliguqukayo — Shayela ngejubane eliphansi (1,500–2,500 RPM) ngokucindezela okungaguquki kuze kube i-EPDM washer icindezelwa kancane ngokumelene neshidi lophahla. Ungaqinisi ngokweqile — I-torque eyeqile izocindezela i-EPDM washer ngaphezu komkhawulo wayo we-elastic futhi ibangele ukuvuza kwamanzi noma ukulimala kweshidi lophahla. Shayela ngokuqondana nendawo — Ukufaka nge-engeli kuvimbela i-washer ukuthi ihlale kahle futhi kudala ukuvalwa okungaphelele. Hlola ngemva kokufaka — Hlola ukuthi wonke ama-washer acindezelwe kahle futhi azikho izikulufu ezishaywe ngokweqile noma eziphumelelayo. Sebenzisa ama-stainless steel drivers — Ukuze ugweme ukugqwala kwe-galvanic, sebenzisa ama-stainless steel noma ama-hex drivers angewona ensimbi. Ungahlanganisi izikulufu ze-stainless steel nama-washer noma izingxenye zensimbi ye-carbon ezindaweni ezigqwalayo. Ukuqinisekiswa Kwekhwalithi Zonke izikulufu zenziwa ngaphansi kokulawulwa kwekhwalithi okuqinile futhi zinganikezwa nge: Izitifiketi Zemboni — imibiko yokuhlolwa kwempahla enokwakheka kwamakhemikhali nezici zemishini (ukuqinisekiswa kwe-AISI 304) Imibiko yokuhlolwa kwe-salt spray — ukuqinisekiswa kwe-neutral salt-spray (ASTM B117) okungaphezu kuka-≥720 amahora Imibiko yokuhlolwa kwamandla okubhoboza — ukuqinisekiswa kokusebenza kokubhoboza Imibiko yokuhlolwa kwe-torque — ukuqinisekiswa kwamandla e-torsional Imibiko yokuhlolwa yabantu besithathu (SGS, BV, TÜV) — kuyatholakala uma kuceliwe Izitifiketi Zokuhlola ze-EN 10204 3.1 — kuyatholakala uma kuceliwe Ulwazi Lokuhlela Ukuze ufake i-oda noma ucele isilinganiso, sicela unikeze: Usayizi wesikulufu (ST4.2, ST4.8, ST5.5, ST6.3 mm) Ubude obudingekayo Inani ngosayizi ngamunye Izidingo zesitifiketi Okukhethwayo kokupakisha
