ASTM A53 Qib B yog cov welded los yog seamless steel yeeb nkab nrog lub zog tsawg kawg nkaus ntawm 240 MPa thiab tensile lub zog ntawm 415 MPa rau kev thauj mus los ntawm cov kua dej tsawg.
ASTM A53 Qib B Piping Hom
Hom F- Rauv-lub taub qab-welded, nruam welded
Nws yog txheej txheem uas cov hlau phaj tau preheated nyob rau hauv lub qhov cub kub kub thiab welded siv vuam consumables.Nyob rau hauv cov txheej txheem vuam, cov hlau phaj yog preheated rau ib tug txaus kub thiab ces welded nyob rau hauv lub cub tawg los ntawm kev siv vuam consumables los tsim ib tug weld seam.Nruam welding txhais tau hais tias cov hlau phaj yog txuas ntxiv welded nyob rau hauv lub cub tawg, tso cai rau kev tsim cov yeeb nkab ntev ntev.
Hom E- Hluav taws xob tiv taus-welded
Qhov no yog txheej txheem vuam nyob rau hauv uas cov npoo ntawm cov hlau phaj yog rhuab thiab nias ua ke los ua ib qho vuam los ntawm kev siv hluav taws xob tam sim no rau ob qho kawg ntawm cov yeeb nkab siv cov cua sov thiab siab.Tsis yog siv cov khoom siv molten welding consumables, tiv thaiv cua sov ua rau cov npoo ntawm cov hlau phaj rau qhov kub txaus thiab siv lub siab los tsim cov vuam ntawm cov npoo ntawm cov hlau phaj.
Hom S - Seamless
Seamless steel yeeb nkab yog tsim ncaj qha rau hauv cov yeeb nkab tsis muaj seams los ntawm dov, tho, los yog extruding.
Cov khoom siv raw
Qhib rauv, hluav taws xob rauv, lossis alkaline oxygen.
Ib lossis ntau qhov txheej txheem yuav raug siv.
Kev kho cua sov
Welds hauvHom E Qib B or Hom F Qib Bcov yeeb nkab yuav tsum tau kho cua sov tom qab vuam kom tsawg kawg yog 1000 ° F [540 ° C] kom tsis muaj martensite tsis muaj, lossis lwm yam kho kom tsis muaj martensite tsis muaj.
