ASTM 1010/1020/1045/4130/4140 Precision Mechanical Seamless Steel Tubes

Lus piav qhia luv luv:

Precision Seamless Steel Piping rau kev siv tshuab thiab teeb pom kev zoo.Qhov no ua rau cov khoom sib xws thoob plaws hauv cov yeeb nkab piv rau cov kav dej txheem.Thaum lub tshuab raj tuaj yeem tsim tau raws li cov qauv tshwj xeeb raws li qhov kev thov, cov khoom "ib txwm" feem ntau ua rau tsom mus rau lub zog tawm los rau qhov tseeb qhov ntev thiab phab ntsa thicknesses.Hauv qee daim ntawv thov tsim hnyav, lub zog tawm los kuj tseem tsis tau teev tseg thiab cov tshuab raj yog tsim "tsim rau siv".Mechanical tubing suav nrog ntau yam kev siv cov qauv thiab tsis yog qauv.

Tshwj xeeb Configurations

Tubular Khoom tshwj xeeb seamless tubing configurations pib nrog lub siab zoo steels.Qib, tshuaj ntsuam xyuas thiab qhov chaw saum npoo yog ua tib zoo txiav txim siab, thiab cov txheej txheem tsim khoom raug txiav kom ua tiav cov raj zoo tshaj plaws rau kev siv kawg.

Cov configurations yog tsim los ntawm round raj los ntawm txias kos duab.Lub raj yog kos los ntawm ib tug zoo li tus mandrel los yog los ntawm ib tug zoo li tus tuag, los yog ob qho tib si.Txhim kho tolerances, finishes thiab mechanical zog tshwm sim.

Seamless thiab welded raj rau txhua yam thiab kev siv engineering.Tubes rau kev tsim kho thiab kev tsim vaj tse xws li kev tsim vaj tse, hauv paus, thiab lwm yam.
