ASTM A500 Square Steel Yeeb Nkab
Cov yeeb nkab steel specification yog seamless txias tsim carbon steel yeeb nkab. Qib ntawm cov yeeb nkab no muaj nyob rau hauv round, square thiab rectangular shapes. Qhov tsawg kawg nkaus tensile zog ntawm ASTM A500 steel yeeb nkab yog 427MPa thiab qhov tsawg kawg nkaus yield zog yog 317MPa. ASTM A500 steel yeeb nkab muaj lub zog tensile siab tshaj plaws. Qhov tsawg kawg nkaus tensile zog ntawm ASTM A500 steel yeeb nkab yog 310MPa thiab qhov tsawg kawg nkaus yield zog yog 228MPa. ASTM A500 No. 40 yeeb nkab yog ib qho ntawm cov kav dej nruab nrab uas tuaj yeem tiv taus siab thiab kub. Cov yeeb nkab muaj nyob rau hauv qhov sib txawv ntawm qhov tiav, thiab qhov tsis tiav yog ASTM A500 dub steel yeeb nkab. Cov tshuaj muaj xws li carbon, manganese, sulfur, phosphorus thiab tooj liab (raws li tau teev tseg). Cov tshuaj sib xyaw ua ke yog lub luag haujlwm rau lub zog thiab corrosion kuj ntawm ASTM A500 yeeb nkab. Cov yeeb nkab kuj tseem tuaj yeem welded los ntawm feem ntau txoj kev vuam, tab sis kev saib xyuas yuav tsum tau ua kom preheat cov yeeb nkab ua ntej vuam los ntawm cov txheej txheem kub xws li arc vuam kom tsis txhob vuam tawg. Kev kho cua sov tom qab vuam kuj tseem yuav tsum tau tom qab vuam kub.

ASTM A500 specification npog welded thiab seamless carbon steel tubing nyob rau hauv ib puag ncig, square, rectangular, thiab "tshwj xeeb" duab rau kev tsim kho thiab cov hom phiaj. BESTAR cov khoom siv thiab cov khoom lag luam square, duab plaub, puag ncig, thiab tshwj xeeb zoo li hluav taws xob tiv thaiv welded (ERW) carbon steel tubing kom tau raws li ASTM A500 Qib A, Qib B, thiab Qib C siv rau kev siv cov qauv.
