Hluav taws xob tsis kam welded (ERW) round steel tubing yog tus neeg sib tw zoo tshaj plaws rau kev ua haujlwm feem ntau. Hlau round tubing muaj nyob rau hauv A500 qib B, A513, thiab A135 nyob ntawm qhov ntev ntawm sab nraud. ERW steel puag ncig cov raj muaj cov tsis-coated, ib nrab du tsaus grey tiav, thiab welded seam nyob rau hauv. Feem ntau siv xws li railings, tso pa, yob tawb, hinges thiab dav siv tubing. ASTM A500 yog cov qauv kev qhia tshwj xeeb rau txias-tsim welded thiab seamless carbon steel structural tubing nyob rau hauv rounds thiab duab. ASTM A513 yog tus qauv specification rau hluav taws xob-kuj-welded carbon thiab alloy steel mechanical tubing. ASTM A135 yog tus qauv specification rau hluav taws xob-kuj-welded steel yeeb nkab.
Cov txheej txheem ERW cuam tshuam nrog kev hla cov hluav taws xob tam sim no los ntawm lub tiaj tus steel sawb lossis coil, ua rau cov npoo kom sov thiab fuse ua ke, tsim cov seam txuas mus rau qhov ntev ntawm lub raj. Cov seam no yog ob qho tib si ruaj khov thiab tus nqi tsim nyog, ua rau ERW round steel hlab yog qhov kev xaiv nrov hauv ntau hom kev siv.
Cov raj no feem ntau yog tsim los ntawm cov hlau, txawm hais tias lawv tuaj yeem tsim los ntawm lwm cov hlau lossis cov khoom siv nyob ntawm cov kev xav tau tshwj xeeb. Lawv muaj nyob rau hauv ntau yam diameters, thicknesses, thiab lengths, tso cai rau yooj yim rau kev tsim thiab tsim.
