Seamless yeeb nkab ua los ntawm ib daim hlau uas tsis muaj seams rau saum npoo yog hu ua seamless steel yeeb nkab. Raws li txoj kev tsim khoom, cov yeeb nkab seamless muab faib ua cov yeeb nkab kub dov, cov yeeb nkab txias txias, cov yeeb nkab txias txias, cov yeeb nkab extruded, cov yeeb nkab sab saum toj, thiab lwm yam. Raws li cov duab ntawm cov seem, cov yeeb nkab steel seamless tau muab faib ua ob hom: ib puag ncig thiab cov duab tsis sib xws, thiab cov yeeb nkab zoo li muaj cov duab plaub, cov duab elliptical thiab lwm yam. Qhov siab tshaj plaws txoj kab uas hla yog 650mm thiab qhov tsawg kawg nkaus txoj kab uas hla yog 0.3mm. Seamless steel yeeb nkab yog siv los ua roj av geological drilling yeeb nkab, tawg yeeb nkab rau petrochemical kev lag luam, boiler yeeb nkab, bearing yeeb nkab thiab high-precision structural steel yeeb nkab rau tsheb, tsheb laij teb thiab aviation.
