Kodi Pali Kusiyana Kotani Pakati pa Ndodo, Tube, ndi Pipe mu Stainless Steel?

1. Mayina a Zogulitsa ndi Matanthauzidwe (Kuyerekeza kwa Chingerezi-Chitchaina)

Dzina lachingerezi Dzina lachi China Tanthauzo & Makhalidwe
Kuzungulira 不锈钢圆钢 (Stainless Steel Round) Nthawi zambiri amatanthauza mipiringidzo yozungulira yotentha, yopindika, kapena yokokedwa ndi ozizira. Kawirikawiri ≥10mm m'mimba mwake, amagwiritsidwa ntchito popititsa patsogolo.
Ndodo 不锈钢棒材 (Ndodo yachitsulo chosapanga dzimbiri) Akhoza kutanthauza ndodo zozungulira, ndodo za hex, kapena ndodo zozungulira. Nthawi zambiri timipiringidzo tolimba m'mimba mwake (monga 2mm-50mm) yokhala ndi mipiringidzo yolondola kwambiri, yoyenera zomangira, zomangira mwatsatanetsatane, ndi zina zambiri.
Mapepala 不锈钢薄板 (Stainless Steel Sheet) Nthawi zambiri ≤6mm mu makulidwe, makamaka ozizira, osalala pamwamba. Amagwiritsidwa ntchito muzomangamanga, zida, zida zakukhitchini, ndi zina.
Mbale 不锈钢中厚板 (Mbale wachitsulo chosapanga dzimbiri) Nthawi zambiri ≥6mm mu makulidwe, makamaka otentha-wodzigudubuza. Oyenera zotengera kuthamanga, zigawo zikuluzikulu, katundu mafakitale ntchito.
Chubu 不锈钢管) Nthawi zambiri amatanthauza machubu opangidwa, amakanika, kapena okongoletsa. Itha kukhala welded kapena yopanda msoko. Imayang'ana kwambiri kulondola kwake komanso mawonekedwe, mwachitsanzo, mipando kapena njanji.
Chitoliro 不锈钢管(工业管)(Paipi Yopanda Zitsulo - Industrial) Amagwiritsidwa ntchito popanga mapaipi amakampani, monga zoyendera zamadzimadzi, zosinthira kutentha, ma boilers. Imagogomezera makulidwe a khoma, kuchuluka kwa kukakamizidwa, ndi mawonekedwe okhazikika (mwachitsanzo, SCH10, SCH40).
 

2. Chidule cha Kusiyana Kwakukulu

Gulu Zolimba Phokoso Main Application Focus Makhalidwe Opanga
Kuzungulira / Ndodo ✅ Inde ❌ Ayi Machining, nkhungu, fasteners Kutentha kotentha, kupangira, kujambula kozizira, kugaya
Mapepala/Mbale ❌ Ayi ❌ Ayi Kapangidwe, zokongoletsera, zotengera zokakamiza Chozizira (chitsamba) / chozizira (mbale)
Chubu ❌ Ayi ✅ Inde Zokongoletsera, zomangamanga, mipando Zowotcherera / zozizira / zopanda msoko
Chitoliro ❌ Ayi ✅ Inde Kuyendera kwamadzi, mizere yothamanga kwambiri Zopanda msoko / zowotcherera, zokhazikika
 

3. Malangizo Okumbukira Mwachangu:

  • Kuzungulira= Zolinga zozungulira zozungulira, pokonza movutikira

  • Ndodo= Kapamwamba kakang'ono, kapamwamba kwambiri

  • Mapepala= Chochepa chathyathyathya (≤6mm)

  • Mbale= Chinthu chokhuthala chathyathyathya (≥6mm)

  • Chubu= Kugwiritsa ntchito zokongoletsa / zomanga

  • Chitoliro= Kwa zoyendera zamadzimadzi (zovotera ndi kukakamiza / muyezo)

 

I. ASTM (American Society for Testing and Equipment)

Ndodo / Round Bar

  • Reference StandardASTM A276 (Mafotokozedwe Okhazikika a Mipiringidzo ya Zitsulo Zosapanga dzimbiri ndi Mawonekedwe - Zotentha-Zodzigudubuza ndi Zozizira)

  • Tanthauzo: Mipiringidzo yolimba yokhala ndi magawo osiyanasiyana opingasa (ozungulira, masikweya, ma hexagonal, ndi zina zotero) omwe amagwiritsidwa ntchito popanga zinthu zambiri komanso kupanga makina.

  • Zindikirani: Mu mawu akuti ASTM, "bar yozungulira" ndi "ndodo" nthawi zambiri amagwiritsidwa ntchito mosiyana. Komabe, "Rod" nthawi zambiri amatanthauza mainchesi ang'onoang'ono, ozizira ozizira okhala ndi vuto lalikulu.

Mapepala / Mbale

  • Reference StandardASTM A240 (Matchulidwe Okhazikika a Chromium ndi Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Application)

  • Kusiyana kwa Tanthauzo:

    • MapepalaKukula: <6.35 mm (1/4 inchi)

    • MbaleKukula ≥ 6.35 mm

  • Zonsezi ndi zinthu zathyathyathya, koma zimasiyana mu makulidwe ndi kuyang'ana kwa ntchito.

Chitoliro

  • Reference StandardASTM A312 (Mafotokozedwe Okhazikika a Mapaipi Opanda Msoko, Owotcherera, ndi Ozizira Kwambiri Ogwira Ntchito Austenitic Azitsulo Zachitsulo)

  • Kugwiritsa ntchito: Amagwiritsidwa ntchito ponyamula madzimadzi. Imatsindika m'mimba mwake, kukula kwa chitoliro chodziwika bwino (NPS), ndi gulu lamphamvu (mwachitsanzo, SCH 40).

Chubu

  • Miyezo Yothandizira:

    • ASTM A269 (Matchulidwe Okhazikika a Seamless and Welded Austenitic Stainless Steel Tubing for General Service)

    • ASTM A554 (Matchulidwe Okhazikika a Welded Stainless Steel Mechanical Tubing)

  • Kuyikira Kwambiri: Akunja awiri ndi pamwamba khalidwe. Amagwiritsidwa ntchito ngati zomangamanga, zamakina, kapena zokongoletsera.

II.ASME (American Society of Mechanical Engineers)

  • MiyezoASME B36.10M / B36.19M

  • Tanthauzo: Tanthauzirani kukula kwake ndi makulidwe a khoma (mwachitsanzo, SCH 10, SCH 40) pazitsulo zosapanga dzimbirimapaipi.

  • Gwiritsani ntchito: Nthawi zambiri amagwiritsidwa ntchito ndi ASTM A312 pamakina apaipi a mafakitale.

III.ISO (International Organisation for Standardization)

  • ISO 15510: Kuyerekeza kwazitsulo zosapanga dzimbiri (sizimatanthawuza mafomu azinthu).

  • ISO 9445: Kulekerera ndi miyeso ya mizere yozizira, mapepala, ndi mbale.

  • ISO 1127: Miyeso yokhazikika yamachubu azitsulo - imasiyanitsachubundichitolirondi awiri akunja vs. awiri mwadzina.

IV.EN (Zotsatira za ku Ulaya)

  • EN 10088-2: Zopangira zitsulo zosapanga dzimbiri (zonse mapepala ndi mbale) pazolinga zonse.

  • EN 10088-3: Zitsulo zosapanga dzimbiri zazitali monga mipiringidzo ndi mawaya.

V. Summary Table - Mtundu wa Zogulitsa ndi Miyezo Yolozera

Mtundu wa Zamalonda Miyezo Yothandizira Mawu Ofunika Kwambiri
Chizungulire / Ndodo ASTM A276, EN 10088-3 Bar yolimba, yokokedwa ozizira kapena yotentha yogudubuzika
Mapepala ASTM A240, EN 10088-2 makulidwe <6mm
Mbale ASTM A240, EN 10088-2 makulidwe ≥ 6mm
Chubu ASTM A269, ASTM A554, ISO 1127 Kuyang'ana kwapakati pakunja, kumagwiritsidwa ntchito popanga kapena kukongoletsa
Chitoliro ASTM A312, ASME B36.19M Kukula kwapaipi kwadzina (NPS), komwe kumagwiritsidwa ntchito ponyamula madzimadzi
