Kev txiav txim cov ntaub ntawv rau ASTMA 653 Galvanized Chev

Kev txiav txim cov ntaub ntawv rau ASTMA 653 Galvanized Chev
Zinc-coated los yog zinc-hlau alloy-coated daim ntawv nyob rau hauv coils thiab txiav lengths yog tsim rau thickness yuav tsum tau qhia rau 0.001 nyob rau hauv. [0.01 mm].Lub thickness ntawm daim ntawv muaj xws li ob qho tib si
lub hauv paus hlau thiab txheej.
Kev txiav txim rau cov khoom rau qhov kev qhia tshwj xeeb no yuav tsum muaj cov ntaub ntawv hauv qab no, raws li qhov tsim nyog, txhawm rau piav qhia txog cov khoom xav tau:
1 Lub npe ntawm cov khoom (cov ntawv hlau, zinc-coated (galvanized) lossis zinc-hlau alloy-coated (galvannealed)),
2 Kev xaiv ntawm daim ntawv [CS (Tom A, B, thiab C), FS (Types A thiab B), DDS (Types A thiab C), EDDS, SS, HSLAS, HSLAS-F, SHS, los yog BHS].
3 Thaum SS, HSLAS, HSLAS-F, SHS, lossis BHS tau teev tseg, qhia qib, lossis chav kawm, lossis sib xyaw ua ke.
4 ASTM tus naj npawb thiab xyoo ntawm qhov teeb meem, raws li A653 rau nti-phaus units lossis A653M rau SI units.
5 Txheej txheej,
6 Tshuaj kho lossis tsis kho tshuaj,
7 Cov roj los tsis yog roj,
8 Minimized spangle (yog tias xav tau),
9 Ntxiv du (yog tias xav tau),
10 Phosphatized (yog tias xav tau),
11 Dimensions (paub thickness, yam tsawg kawg nkaus los yog nominal, dav, flatness yuav tsum, thiab ntev, (yog txiav lengths)).
12 Coil loj qhov yuav tsum tau muaj (xws li qhov siab tshaj plaws sab nraud txoj kab uas hla (OD), tau txais hauv txoj kab uas hla (ID), thiab qhov hnyav tshaj plaws [mas]),
13 Ntim,
14 Daim ntawv pov thawj, yog tias xav tau, ntsuas kub thiab ntsuas cov cuab yeej cuab tam,
15 Daim Ntawv Thov (ib feem txheeb xyuas thiab piav qhia), thiab
16 Cov kev cai tshwj xeeb (yog tias muaj).
16.1 Yog tias xav tau, cov khoom yuav raug txiav txim rau lub hauv paus hlau thickness
16.2 Yog tias xav tau, cov khoom yuav raug txiav txim rau ib qho chaw ib leeg / ib sab txheej txheej
16.3 Thaum tus neeg yuav khoom xav tau cov thickness kam rau ua rau 3⁄8-hauv.[10-mm] qhov tsawg kawg nkaus ntawm ntug qhov kev xav tau no yuav tsum tau teev nyob rau hauv daim ntawv xaj khoom lossis daim ntawv cog lus.
CEEB TOOM 1-Cov lus piav qhia zoo li nram no: steel ntawv, zinc-coated, lag luam steel hom A, ASTM A653, Txheej Txheej G115, tshuaj kho, oiled, yam tsawg kawg nkaus 0.040 los ntawm 34 los ntawm 117 nyob rau hauv., rau cov tso tsheb hlau luam, los yog steel ntawv , zinc-coated, siab zog qis alloy steel Qib 340, ASTM A653M, Txheej Txheej Z275, minimized spangle, tsis tshuaj kho, oiled, yam tsawg kawg nkaus 1.00 los ntawm 920 hli los ntawm kauj, 1520-mm siab tshaj OD, 600-mm ID, 10 000 -kg siab tshaj plaws, rau tsheb laij teb sab hauv fender.
CEEB TOOM 2-Tus neeg yuav khoom yuav tsum paub tias muaj kev hloov pauv hauv kev tsim cov kev coj ua ntawm cov neeg tsim khoom thiab yog li tau qhia kom tsim cov txheej txheem tsim khoom (lossis lub neej ntawd) cov txheej txheem rau cov tuab tuab.
