L415 pipeline yeeb nkab yog qib siab - qib steel pipeline yeeb nkab rau roj thiab roj tsheb thauj mus los, ua raws li GB / T9711-2017 thiab API 5L cov qauv.
Core technical parameters yog reflected nyob rau hauv nws mechanical zog thiab dimensional specifications:
Mechanical Properties:
Tawm Zog: 415-565MPa
Tensile Strength: Ntau dua lossis sib npaug rau 520MPa
Elongation tom qab Fracture: Ntau dua lossis sib npaug li 18%
Impact Test Kub: 0 degree, -20 degree, thiab lwm yam, nyob ntawm qib
Impact Zog: Ntau dua lossis sib npaug rau 34J
Hardness: Brinell Hardness Tsawg dua los yog sib npaug rau 250HB
Tshuaj muaj pes tsawg leeg:
Cov ntsiab lus carbon: Tsawg dua lossis sib npaug rau 0.26%
Manganese Cov ntsiab lus: 1.20-1.80%
Silicon Cov ntsiab lus: Tsawg dua lossis sib npaug rau 0.45%
Cov ntsiab lus phosphorus: Tsawg dua lossis sib npaug rau 0.025%
Cov ntsiab lus sulfur: Tsawg dua lossis sib npaug rau 0.025%
Cov ntsiab lus microalloying xws li niobium, vanadium, thiab titanium feem ntau ntxiv, thiab cov txheej txheem tswj dov thiab txias yog siv los txhim kho kev ua tau zoo tag nrho.
Qhov Loj Specifications: Sab nraud txoj kab uas hla feem ntau yog li ntawm 21.3 mus rau 1422 hli; phab ntsa thickness li ntawm 2.0 mus rau 40.0 hli; Qhov ntev feem ntau yog li ntawm 6 mus rau 12 m. Peb tuaj yeem tsim cov qauv ntev, kev cai ntev, thiab ntau lub raj ntev.
L415 cov kav dej kav dej tau dav siv hauv ntau qhov kev lag luam, feem ntau suav nrog:
- Roj thiab nkev tsheb thauj mus los: Siv nyob rau hauv ntev -kab raj xa dej mus thauj cov roj av, roj av, thiab lwm yam kev tshaj tawm.
- Cov kav dej hauv nroog hauv nroog: Ua haujlwm ua cov khoom siv tseem ceeb rau kev thauj mus los hauv nroog, ua kom muaj kev nyab xeeb ntawm cov khoom siv roj rau cov neeg nyob hauv thiab kev lag luam.
- Kev lag luam tshuaj: Siv los thauj ntau yam tshuaj lom neeg, xws li roj av liquefied roj av (LPG) thiab ammonia.
- Kev txuag dej: Qee qhov chaw txuag dej kuj tseem siv cov yeeb nkab steel no rau kev thauj dej lossis kev txhawb nqa.
