Navigation Khawm
AS 1074 Standard Overview
| Scope | Qhia meej txog cov kev xav tau rau threaded steel tubes thiab tubular, thiab cov leeg-kawg steel hlau tsim nyog rau cov ntsia hlau raws li tau teev tseg hauv AS 1722.1 |
| Kev faib tawm | Peb phab ntsa thicknesses ntawm lub raj: xaiv Lub Teeb, Nruab Nrab, thiab Hnyav |
| Tube | Yuav ua tau welded thiab seamless hlab: ntev ntawm uniform ncig hollow seem |
| Ntsia Hlau Xov | Threaded raj yuav tsum ua raws li AS 1722.1 |
| Sab nraud txoj kab uas hla | DN 8 txog DN 150 suav nrog (nominal loj) |
| Phab ntsa Thickness | 1.8mm-5.4 hli |
| txheej | Varnish txheej, galvanized, 3 txheej PE, FBE, thiab lwm yam. |
| Cov txheej txheem ntsig txog | ISO 65; ISO 3183; ASTM A53; ASTM A106; BS EN 10255; BS 1387; DIN 2440; DIN 2448; JIS G 3452; JIS G 3454; CSA Z245.1; GOST 10751SAPI-21; EN 10217-1; thiab lwm yam. |
AS 1074 Chemical Composition
| tshuaj muaj pes tsawg leeg | thaj tsam |
| CE(Carbon sib npaug) | ≤0.4 |
| P(Phosphorus) | max 0.045% |
| S(Sulfur) | max 0.045% |
CE(Carbon sib npaug) =C+Mn/6
Phosphorus (P)thiabSulfur (S):Ob lub ntsiab lus no txo qhov toughness thiab weldability ntawm steel.High phosphorus thiab sulfur qib yuav ua rau cov hlau ua nkig, tshwj xeeb tshaj yog nyob rau qhov kub thiab txias.
Carbon sib npaug (CE):Qhov no yog ib qho kev ntsuas ntawm weldability ntawm steel uas yuav siv sij hawm mus rau hauv tus account tus nqi ntawm carbon nyob rau hauv cov hlau thiab lwm yam alloying ntsiab (xws li, manganese, chromium, molybdenum, thiab lwm yam) uas cuam tshuam rau nws weldability.Qhov siab dua qhov sib npaug ntawm cov pa roj carbon monoxide, qhov tsawg dua weldable cov hlau yog thiab ntau preheating thiab tom qab kho kev ntsuas yuav tsum tau rau vuam.
