ASTM A778 Hlau Yeeb Nkab
Qhov kev qhia tshwj xeeb no suav nrog cov seam ncaj thiab kauv taub qab seam welded unannealed austenitic stainless hlau tubular cov khoom tsim los rau qis thiab nruab nrab kub thiab corrosive qhov kev kho mob tsis tsim nyog rau corrosion kuj.Cov khoom siv tubular yuav tsum tau ua los ntawm cov ntawv tiaj tus dov steel, coil, lossis phaj los ntawm cov txheej txheem tiv thaiv arc-welding.
Peb Cov Hlau yog ib tus neeg muab khoom lag luam lees paub thiab xa tawm ntawm ASTM A778 Austenitic Stainless Steel Tubes, uas muaj ntau tus cwj pwm zoo los muab kev ua haujlwm zoo, lub zog siab, xeb pov thawj, thiab lwm yam.Cov qib siab tshaj ntawm cov hlau thiab cov thev naus laus zis siab dua yog kev koom ua ke hauv kev tsim cov raj no.Peb muab cov khoom no rau qhov tshwj xeeb nto tiav rau qhov zoo nkauj thiab zoo heev tiv thaiv corrosion.ASTM A778 Welded Tubes yog tsim los ntawm peb cov kws txawj txhim khu kev qha los ntawm kev siv qib zoo tshaj plaws ntawm stainless hlau.Txhawm rau kom haum rau ntau yam kev xav tau ntawm cov neeg siv khoom, peb muab cov raj no hauv qhov sib txawv, qhov tshwj xeeb thiab qib.Clientele tuaj yeem tau txais cov khoom lag luam no los ntawm peb hauv cov duab sib txawv xws li duab plaub / oval / round / square thiab lwm yam cuam tshuam cov profile raws li lawv xav tau.Yog li txhawm rau ntxiv dag zog rau peb txoj haujlwm, peb tau tsim cov khoom lag luam uas nws kim heev thiab muaj txiaj ntsig zoo ntawm cov raj no.Kev txhawb nqa los ntawm peb cov kev paub txog kev lag luam loj, peb nqa cov Tubes rau peb cov neeg siv khoom hwm.
Cov yeeb nkab steel no yog tsim los ntawm kev siv cov khoom siv zoo tshaj plaws thiab cov cuab yeej ua haujlwm zoo hauv tandem rau cov qauv kev txheeb xyuas ua ke.Cov yeeb nkab steel uas tau nthuav tawm los ntawm peb tau tshuaj xyuas raws li qhov zoo ua ntej muab rau peb cov neeg siv khoom.Cov ASME SA 778 Tubes muaj ntau yam zoo xws li Resistant tiv thaiv xeb, Durability, Robustness, Non-corrosive, Siab tensile lub zog, Fine tiav, Txhim khu kev qha, Resistance tiv thaiv abrasion, Perfect tiav, muaj zog tsim, siab ruaj, siab tsis kam, ntev. lub neej, Nqi zoo, Yooj yim rau nruab, Durable, Siab zog, tuaj yeem tiv taus siab siab thiab lwm yam.
Qhov kev qhia tshwj xeeb no suav nrog cov khoom siv welded unannealed tubular 3 in. (75 mm) txog 48 nti.(1200 hli) nyob rau hauv sab nraud txoj kab uas hla thiab nyob rau hauv nominal phab ntsa thicknesses ntawm 0.062 nyob rau hauv. (1.5 hli) txog 0.500 nyob rau hauv. (12.5 hli) ua rau no specification.Tubular cov khoom uas muaj lwm yam diameters, los yog phab ntsa thickness, los yog ob qho tib si tej zaum yuav muab muab tso rau nws ua raws li tag nrho cov lwm yam yuav tsum tau ntawm no specification.
