FAQ
Q1: Qhov twg yog qhov pheej yig dua - ASTM B111 C68700 lossis C70600?
A: C68700 yog 40-50% pheej yig dua rau tib qhov ntev.
Piv txwv li: 25mm x 2.0mm tube. C68700=$11-14/kg. C70600=$18-24/kg. Rau qhov project 5,000-meter, C68700 txuag $ 40,000-60,000. Tsuas yog them rau C70600 yog tias koj xav tau nws.
Q2: Puas yog C70600 kav ntev dua C68700 hauv dej hiav txwv?
A: Yog - 20-25 xyoo vs 15-20 xyoo rau C68700 hauv dej hiav txwv huv.
C70600 has no zinc, so no dezincification. However, the 5-year difference matters only for projects with >20 xyoo tsim lub neej. Rau 15-xyoo txoj haujlwm, ob qho tib si dhau qhov yuav tsum tau - yog li yuav tus pheej yig dua (C68700).
Q3: C68700 puas tuaj yeem hloov C70600 hauv cov tshuab uas twb muaj lawm?
A: Yog - yog tias lub kaw lus tsis muaj ammonia thiab kub<70°C.
GNEE tau pab 30+ cov nroj tsuag hloov C70600 nrog C68700. Siv tib qhov ntev. Nano- kho C68700 sib tw C70600 corrosion kuj nyob rau hauv feem ntau. Txuag: 30-50% ntawm cov nqi hloov raj.
Q4: Lub zog tensile sib txawv ntawm C68700 thiab C70600 yog dab tsi?
A: C68700 muaj zog dua - 550-750 MPa vs 350-520 MPa rau C70600.
Ntau tus neeg yuav khoom xav tias C70600 muaj zog dua vim tias nws raug nqi ntau dua. Tsis muaj tseeb. Rau siab -lub tshuab siab, C68700 yog qhov kev xaiv zoo dua mechanically.
Q5: Puas yog GNEE Tshuag ob C68700 thiab C70600?
A: Yog - GNEE cov khoom lag luam ob qho tib si ntawm peb lub tuam txhab Tuam Tshoj.
C68700 Tshuag: 50+ tons (12-50mm OD, 2-5mm phab ntsa). C70600 Tshuag: 10-15 tons (limited ntau thiab tsawg). Rau C70600, paub meej tias Tshuag ua ntej xaj. Lub sij hawm ua cov khoom tsis-Tshuag C70600: 30-40 hnub.
Q6: Kuv yuav txiav txim siab li cas cov hlau yuav yuav rau kuv qhov project?
A: Siv cov ntoo txiav txim siab GNEE hauv Tshooj 6.
Teb peb lo lus nug: (1) Puas muaj ammonia? (2) Puas yog qhov kub siab tshaj 80 degree? (3) Puas yog tsim lub neej tshaj 20 xyoo? Yog tias muaj rau ib qho - xav txog C70600. Yog tias tsis yog txhua tus - yuav C68700.
Q7: Tus nqi sib txawv rau nano{1}}kho C68700 vs C70600 yog dab tsi?
A: Nano- kho C68700 ($ 14-18/kg) tseem 15-25% pheej yig dua C70600 ($ 18-24/kg).
Nano- kho C68700 ntxiv 40% corrosion lub neej, kaw qhov sib txawv nrog C70600. Rau cov dej hiav txwv muaj kuab paug, GNEE pom zoo kom nano- kho C68700 dhau tus qauv C70600 - qhov ua tau zoo sib xws ntawm tus nqi qis.
