Uyini Umehluko Phakathi Kwenduku, Ipayipi, kanye Nepayipi Ngensimbi Engagqwali?

1. Amagama Nezincazelo Zomkhiqizo (Ukuqhathaniswa KwesiNgisi NesiShayina)

Igama lesiNgisi Igama lesiShayina Incazelo kanye nezici
Isiyingi 不锈钢圆钢 (I-Stainless Steel Round) Ngokuvamile kubhekisela emigoqweni eqinile eyindilinga egoqwe ngokushisa, eyenziwe ngobumba, noma edonswa ngokubandayo. Ngokuvamile ububanzi obuyi-≥10mm, busetshenziselwa ukucutshungulwa okuqhubekayo.
Induku 不锈钢棒材 (Induku Yensimbi Engagqwali) Kungabhekisela ezindongeni eziyindilinga, ezindongeni ze-hex, noma ezindongeni zesikwele. Ngokuvamile imigoqo eqinile emincane enobubanzi obungu-2mm–50mm) enokunemba okuphezulu, efanelekile kuma-fasteners, izingxenye zomshini wokunemba, njll.
Ishidi 不锈钢薄板 (Ishidi Lensimbi Engagqwali) Ngokuvamile ubukhulu bayo buyi-≤6mm, ikakhulukazi igoqeka ngokubandayo, inobuso obubushelelezi. Isetshenziswa ekwakhiweni kwezakhiwo, izinto zikagesi, imishini yasekhishini, njll.
Ipuleti 不锈钢中厚板 (I-Stainless Steel Plate) Ngokuvamile ubukhulu obungu-≥6mm, ikakhulukazi i-hot-rolled. Ifanelekela imithambo yokucindezela, izingxenye zesakhiwo, ukusetshenziswa kwezimboni okunzima.
Ipayipi 不锈钢管(装饰管)(Ishubhu yensimbi engagqwali – Ehlobisayo/Eyesakhiwo) Ngokuvamile kubhekisela kupayipi lesakhiwo, elemishini, noma elihlobisayo. Lingashintshwa noma lingenamthungo. Ligxila ekuqondeni nasekubukekeni kobukhulu, isib. ifenisha noma izinsimbi.
Ipayipi 不锈钢管(工业管)(Ipayipi Lensimbi Engagqwali - Imboni) Ivame ukusetshenziswa kumapayipi ezimboni, njengokuthuthwa koketshezi, ama-heat exchanger, ama-boiler. Igcizelela ubukhulu bodonga, isilinganiso sokucindezela, kanye nemininingwane ejwayelekile (isb., i-SCH10, i-SCH40).
 

2. Isifinyezo Somehluko Oyinhloko

Isigaba Okuqinile Imbobo Ukugxila Okuyinhloko Kohlelo Lokusebenza Izici Zokukhiqiza
Isiyingi/Induku ✅ Yebo ❌ Cha Umshini, isikhunta, izikhonkwane Ukugoqa okushisayo, ukwakheka, ukudweba okubandayo, ukugaya
Ishidi/Ipuleti ❌ Cha ❌ Cha Isakhiwo, umhlobiso, imithambo yokucindezela I-cold-rolled (sheet) / i-hot-rolled (plate)
Ipayipi ❌ Cha ✅ Yebo Ukuhlobisa, isakhiwo, ifenisha Kushiselwe / kudonswe kubanda / kuthungwe kahle
Ipayipi ❌ Cha ✅ Yebo Ukuthuthwa koketshezi, imigqa yokucindezela okuphezulu Izilinganiso ezihlanganisiwe/ezihlanganisiwe, ezijwayelekile
 

3. Amathiphu Okukhumbula Okusheshayo:

  • Isiyingi= Ibha eyindilinga yenhloso ejwayelekile, yokucubungula okungahleliwe

  • Induku= Ibha encane, enembile kakhulu

  • Ishidi= Umkhiqizo omncane oyisicaba (≤6mm)

  • Ipuleti= Umkhiqizo ojiyile oyisicaba (≥6mm)

  • Ipayipi= Kokusetshenziswa kobuhle/kwesakhiwo

  • Ipayipi= Kokuthuthwa koketshezi (okulinganiselwe ngokucindezela/okujwayelekile)

 

I. I-ASTM (i-American Society for Testing and Materials)

Induku/Ibha Eyindilinga

  • Izinga Elijwayelekile Lokubhekisela: I-ASTM A276 (Incazelo Ejwayelekile Yamabha Nezimo Zensimbi Engagqwali – Egoqekile Futhi Edonswe Ngobandayo)

  • Incazelo: Imigoqo eqinile enezingxenye ezahlukahlukene eziphambeneyo (eyindilinga, eyisikwele, enezinhlangothi eziyisithupha, njll.) esetshenziselwa izinhlelo zokusebenza ezijwayelekile zesakhiwo kanye nemishini.

  • Inothi: Ngokwegama le-ASTM, elithi “ibha eyindilinga” kanye nelithi “induku” zivame ukusetshenziswa ngokushintshana. Kodwa-ke, elithi “induku” livame ukubhekisela kubha encane, edonswa ngokubandayo enokunemba okuphezulu.

Ishidi / Ipuleti

  • Izinga Elijwayelekile Lokubhekisela: I-ASTM A240 (Incazelo Ejwayelekile ye-Chromium kanye ne-Chromium-Nickel Stainless Steel Plate, Ishidi, kanye ne-Strip ye-Pressure Vessels kanye ne-General Applications)

  • Umehluko Wezincazelo:

    • Ishidi: Ubukhulu < 6.35 mm (1/4 intshi)

    • Ipuleti: Ubukhulu ≥ 6.35 mm

  • Zombili ziyimikhiqizo eyisicaba, kodwa ziyahlukahluka ngobukhulu kanye nokugxila kokusetshenziswa.

Ipayipi

  • Izinga Elijwayelekile Lokubhekisela: I-ASTM A312 (Incazelo Ejwayelekile Yamapayipi Ensimbi Engagqwali E-Austenitic Angenamthungo, Ashiselwe, Futhi Abandayo Kakhulu)

  • Isicelo: Isetshenziselwa ukuthutha uketshezi. Igcizelela ububanzi bangaphakathi, usayizi wepayipi elijwayelekile (i-NPS), kanye nesigaba sokucindezela (isb., i-SCH 40).

Ipayipi

  • Izindinganiso Zokubhekisela:

  • I-ISO 9445: Ukubekezelelana nobukhulu bomugqa ogoqwe ngokubandayo, ishidi, kanye nepuleti.

  • I-ISO 1127Ubukhulu obujwayelekile bamashubhu ensimbi - buhlukanisaipayipifuthiipayipiububanzi bangaphandle uma kuqhathaniswa nobubanzi obujwayelekile.

IV.I-EN (Imithetho YaseYurophu)

  • I-EN 10088-2: Imikhiqizo eyisicaba yensimbi engagqwali (kokubili ishidi kanye nepuleti) ngezinjongo ezijwayelekile.

  • I-EN 10088-3: Imikhiqizo emide yensimbi engagqwali njengemigoqo nezintambo.

V. Ithebula Elifingqiwe - Uhlobo Lomkhiqizo kanye Nezindinganiso Zokubhekisela
