EN 10216-5 1.4301 Seamless stainless hlau raj
Tso lus
GNEEmuaj ntau tshaj 18 xyoo ntawm kev ua haujlwm thiab ua raws li EN 10216-5 TC1 / TC2 cov qauv. Peb muab cov ntaub ntawv pov thawj kev txhawb nqa, suav nrog EN 10204 3.1 daim ntawv pov thawj tshuaj xyuas thiab tag nrho ISO zoo system ua raws, ua kom peb cov raj ua tau raws li qhov xav tau ntawm kev lag luam hnyav.
EN 10216-5 1.4301 seamless stainless hlau rajyog tsim los siv seamless txias txias los yog kub xov txheej txheem, ua raws li yuav tsum tau kev daws annealing. Qhov no ua kom lub cev tsis sib xws austenitic microstructure thiab tshem tawm cov kev ntxhov siab seem, txhim kho corrosion kuj thiab txhua yam ruaj khov.
1.4301 (304) stainless hlau qib nta cov ntsiab lus carbon tsawg (tsawg dua lossis sib npaug li 0.07%), uas txo qhov kev pheej hmoo ntawm kev hnov qab thiab txhim kho weldability. Tom qab kev daws teeb meem annealing, tag nrho cov raj tau txais qhov tseeb pickling thiab passivation, ua rau kom huv si, nplai -dawb nto nrog ib tug roughness ntawm Ra Less tshaj los yog sib npaug zos rau 1.0 μm. Qhov no txhim kho ob qho tib si corrosion kuj thiab dej huv.
Tsis tas li ntawd, kev tswj xyuas nruj nruj yog ua raws li EN ISO 1127 cov qauv, nrog rau chav kawm D2 / D3 thiab T3 kam rau ua. Qhov no ua kom muaj qhov tseeb qhov tseeb zoo rau cov ntawv thov tseem ceeb xws li cov khoom siv hluav taws xob thiab cov tshuab siv tshuaj.
Tsis tas li ntawd, peb cov 1.4301 seamless stainless hlau raj muaj nrog customizable txheej diameters li ntawm 6 hli mus rau 711 hli thiab phab ntsa thicknesses txog 30 hli. Cov raj no ua tau raws li ntau yam kev xav tau ntawm kev lag luam thiab tau siv dav hauv cov cuab yeej siv siab, cov khoom siv hluav taws xob, thiab cov tshuab ua tshuaj lom neeg.

EN 10216-5 1.4301 Seamless tubes Kev kho cua sov
Tus qauv xav tau kev daws teeb meem annealing (+ AT).
Cov hlab yog rhuab mus rau 1040℃mus rau 1100 degree, ces txias sai heev (dej quenching los yog cua quenching).
Qhov txawv ntawm 1.4301 thiab 1.4307 yog dab tsi?
1.4301 muaj cov ntsiab lus carbon siab txog 0.07%. Nws muaj lub zog siab, tab sis nws yooj yim rau carbide nag lossis daus thaum welding, ua rau intergranular corrosion . 1.4307 muaj cov ntsiab lus qis dua (tsawg dua lossis sib npaug li 0.03%), ua rau nws nyiam xaiv rau tuab - cov ntawv siv vuam phab ntsa thiab ua kom muaj kev tiv thaiv corrosion hauv tshav kub- cuam tshuam cheeb tsam (HAZ).
EN 10216-5 vs ASTM A312 Stainless hlau yeeb nkab
EN 10216-5 npog austenitic thiab duplex stainless hlau rau kev siv siab, thaum ASTM A312 npog welded thiab seamless austenitic stainless hlau tubing. Muaj qhov sib txawv tseem ceeb ntawm ob qho tib si ntawm cov khoom siv nomenclature, cov qauv kev sim, thiab kev tso cai kam rau ua.
EN 10216-5 1.4301 tub xa khoom
GNEE stainless hlau tuav PED ntawv pov thawj, uas ua raws li European Pressure Equipment Directive. Txuas nrog yog MTC (cov ntaub ntawv pov thawj) peb xa mus rau peb cov neeg siv khoom German / Italian lub lim tiam dhau los; koj tuaj yeem pom tias cov tshuaj muaj pes tsawg leeg thiab cov ntaub ntawv kuaj hydrostatic yog qhov zoo tshaj rau cov qauv kev cai.

Kev soj ntsuam zoo
Peb nkag siab cov kev cai nruj nruj rau kev siv siab. Peb cov kav dej yog tsim los ntawm cov kav dej loj perforated, tsis tsuas yog kos cov kav dej. Txhua cov yeeb nkab tau dhau 100% eddy tam sim no kuaj (ET) thiab kuaj ultrasonic (UT) ua ntej tawm hauv lub Hoobkas kom ntseeg tau tias cov yeeb nkab phab ntsa tsis muaj qhov tsis xws luag.
Siab -Kev ntim khoom hiav txwv zoo
Plastic Caps: Tiv thaiv plua plav, ya raws, lossis cov khoom txawv teb chaws nkag mus rau hauv cov raj, thiab tiv thaiv cov bevels los ntawm kev cuam tshuam.
Lub Tes Tsho Yas: Txhua lub raj yog ib lub hnab ntim los tiv thaiv khawb los ntawm kev sib txhuam ntawm cov raj.
Woven Bag Wrapping: Rau kev qhwv sab nraud ntawm tag nrho cov pob ntawm cov hlab.
Ntoo Ntoo Cases / Crates: Rau export.
Peb cog lus tias yuav muab "cov duab ntim thiab ntim cov yeeb yaj kiab" ua ntej xa khoom.
