AS 1074 (NZS 1074)yog Australian (New Zealand) lub hom phiaj dav dav hlau yeeb nkab thiab fittings.
Nws siv rau threaded steel kav thiab fittings teev nyob rau hauv AS 1722.1, thiab flat-ended steel kav los ntawm DN 8 mus rau DN 150.
Peb phab ntsa tuab ntawm cov yeeb nkab steel kuj tau teev tseg, lub teeb, nruab nrab, thiab hnyav.
| Txuj | P | S | CE |
| AS 1074 (NZS 1074) | 0.045% max | 0.045% max | 0.4 max |
CE yog luv luv rau carbon sib npaug, uas yuav tsum tau muab los ntawm kev suav.
CE = C + Mn/6
Yam tsawg kawg yield zog: 195 MPa;
Tsawg tensile zog: 320 - 460 MPa;
Elongation: tsis pub tsawg tshaj 20%.
Txhua cov yeeb nkab steel yuav tsum tau sim los ntawm kev xaiv ib qho ntawm cov yeeb nkab steel nruj txoj kev sim.
Hydrostatic Test
Cov yeeb nkab steel tuav tus nqi dej siab ntawm 5 MPa rau lub sijhawm ntev txaus yam tsis muaj qhov xau.
Kev kuaj tsis raug
Eddy qhov kev xeem tam sim no yog raws li AS 1074 Daim Ntawv Ntxiv B.
Kev kuaj ultrasonic raws li AS 1074 Cov Ntawv Ntxiv C.
Phab ntsa thickness qib: lub teeb, nruab nrab, thiab hnyav.
Cov phab ntsa tuab qib ntawm cov yeeb nkab steel sib txawv thiab yog li ua qhov sib thooj sab nraud txoj kab uas hla.Hauv qab no yog ib lub rooj ntawm qhov hnyav ntawm peb qib ntawm cov yeeb nkab steel thiab qhov sib thooj OD tolerances.

Yog tias AS 1074 steel yeeb nkab yog galvanized, nws yuav tsum ua raws li AS 1650.
Qhov saum npoo ntawm cov yeeb nkab galvanized yuav tsum tsis tu ncua, kom du thiab sib npaug li sai tau, thiab tsis muaj qhov tsis xws luag uas yuav cuam tshuam rau kev siv.
Cov yeeb nkab nrog threads yuav tsum tau galvanized ua ntej threading.
Tubes yuav tsum txawv ntawm cov xim ntawm ib kawg raws li hauv qab no:
| Tube | Xim |
| Lub teeb lub raj | Xim av |
| Lub raj nruab nrab | Xiav |
| Lub cev hnyav | Liab |
Peb yog ib tug zoo welded carbon steel yeeb nkab chaw tsim tshuaj paus thiab tsum los ntawm Tuam Tshoj, thiab kuj yog ib tug seamless steel yeeb nkab stockist, muab koj ib tug ntau yam ntawm cov yeeb nkab steel kev daws teeb meem!
