Kab lus no muab cov ntsiab lus ntawm cov khoom siv, cov lus qhia tshwj xeeb, cov yam ntxwv tseem ceeb, tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv lub cev, cov khoom siv lub cev, cov txheej txheem kev ua haujlwm, qib steel, kev siv, thiab lwm cov qib ntawm GB / T 5310 high-pressure steel hlab.

Khoom siv thiab Specification

GB / T 5310 high-pressure steel hlab yog tsim los ntawm cov pa roj carbon zoo lossis hlau alloy steel. Cov raj yog tsim los ntawm cov txheej txheem seamless, kom ntseeg tau tias qhov tseeb qhov tseeb thiab qhov chaw tiav. Tus qauv qhia cov kev cai hauv qab no rau cov raj no:

Sab nraud txoj kab uas hla: 48-457mm

Phab ntsa thickness: 3.91-57mm

Ntev: 3-12.5m

Ntsiab nta

GB / T 5310 high-pressure steel hlab muaj ntau yam tseem ceeb uas ua rau lawv tsim nyog rau kev thov:

High Pressure Resistance: Cov raj no yog tsim los tiv thaiv kev kub ntxhov, ua kom ntseeg tau qhov kev ua tau zoo hauv qhov chaw tseem ceeb.

Temperature Resistance: Cov hlab steel muaj qhov ua tau zoo heev rau qhov kub thiab txias, ua rau lawv tsim nyog rau cov ntawv thov uas muaj cua sov heev.

Superior Strength: GB / T 5310 steel hlab muaj lub zog tshwj xeeb, ua rau lawv tiv taus hnyav thiab kev ntxhov siab.

Corrosion Resistance: Cov hlab yog resistant rau corrosion, kom ntseeg tau tias ntev thiab durability nyob rau hauv corrosive ib puag ncig.

Seamless Kev Tsim Kho: Cov txheej txheem tsim seamless ua kom zoo ib yam, lub zog, thiab kev ncaj ncees thoob plaws hauv lub raj ntev.
