Tsis tas li ntawd, muaj GB / T17396-2007 (Kub dov seamless steel kav rau hydraulic props), GB3093-1986 (High siab seamless steel kav rau diesel xyaw), GB / T3639-1983 (Cold drawn los txias dov precision seamless steel kav). ), GB / T3094-1986 (Cold drawn seamless steel kav nrog cov duab tsis zoo), GB / T8713-1988 (Precision puab txoj kab uas hla seamless steel kav rau hydraulic thiab pneumatic thooj voos kheej kheej), GB13296-2007 (Stainless steel seamless steel kav rau boilers thiab cua sov exchangers), GB / T14975-1994 (Stainless steel seamless steel kav rau lub hom phiaj) GB / T14976-1994 (Stainless Steel Seamless Steel Tubes rau Fluid Transportation) GB / T5035-1993 (Seamless Steel Tubes rau Automotive Halfshaft Sleeves), API -1999 (Specification rau tes tsho thiab Tubing), thiab lwm yam.
Yuav ua li cas txheeb xyuas qhov zoo ntawm seamless steel kav?
1. Cov kav hlau tsis zoo thiab tsis zoo yog qhov yooj yim rau folding.
Folding yog ntau yam creases tsim nyob rau saum npoo ntawm cov kav dej steel, uas feem ntau khiav los ntawm cov kev taw qhia longitudinal ntawm tag nrho cov khoom.Yog vim li cas rau folding yog vim kev nrhiav kev ua haujlwm siab los ntawm cov tuam txhab cuav thiab cov khoom lag luam tsis zoo, uas ua rau txo qis ntau dhau thiab tsim pob ntseg.Folding tshwm sim thaum lub sij hawm tom ntej dov txheej txheem, thiab cov khoom folded yuav tawg tom qab khoov, uas ua rau ib tug tseem ceeb txo nyob rau hauv lub zog ntawm cov hlau.
2. Cov tsos ntawm cov kav hlau tsis zoo thiab tsis zoo feem ntau qhia pitting.
Pitted nto yog ib qho teeb meem tshwm sim los ntawm kev hnav hnyav thiab tsim kua muag ntawm qhov dov zawj, uas ua rau muaj qhov tsis sib xws ntawm cov hlau nto.Vim muaj kev nrhiav nyiaj txiag los ntawm cov khoom cuav thiab cov yeeb nkab tsis zoo, feem ntau muaj cov txheej txheem dov grooves tshaj tus qauv.
3. Qhov saum npoo ntawm cov kav hlau tsis zoo thiab tsis zoo yog qhov ua rau scabbing.
Muaj ob qho laj thawj: (1) Cov khoom siv ntawm cov kav hlau tsis zoo thiab cov kav hlau tsis zoo yog qhov tsis sib xws thiab muaj ntau yam impurities.(2) Cov khoom cuav thiab cov khoom tsis zoo
