Seamless steel kav yog ua los ntawm ib puag ncig steel perforated. Cov kav hlau uas tsis muaj welds ntawm qhov chaw yog hu ua seamless steel kav. Raws li txoj kev tsim khoom, seamless steel kav yuav muab faib ua kub dov seamless steel kav, txias dov seamless steel kav, txias-draw seamless steel kav, extruded seamless steel kav, jacked kav, thiab lwm yam. Raws li cov cross-sectional zoo li, seamless steel kav muab faib ua ob hom: puag ncig thiab tshwj xeeb-puab.
Cov kav dej tshwj xeeb muaj ntau yam duab xws li square, oval, daim duab peb sab, hexagon, melon-puab, lub hnub qub, thiab finned kav. Qhov siab tshaj plaws txoj kab uas hla yog 900 hli thiab qhov tsawg kawg nkaus txoj kab uas hla yog 4 hli. Raws li kev siv sib txawv, muaj tuab-walled seamless steel kav thiab nyias-walled seamless steel kav. Seamless steel kav yog siv los ua roj av geological drilling kav, tawg kav rau
petrochemical kev lag luam, boiler kav, bearing kav, thiab high-precision structural steel kav rau tsheb, tsheb laij teb, thiab aviation.
