A269 Kub Exchanger Tube

 

A269 tshav kub pauv cov raj yog cov hlau ua los ntawm austenitic stainless hlau. Cov txheej txheem dov muaj xws li kub dov, kub extrusion, thiab txias kos duab (rolling) ntawm stainless hlau hlab. Vim muaj cov kua dej ua haujlwm siab thiab tsis yooj yim ntawm kev tu hauv cov kab me me A269 316L stainless hlau hlab, lawv muaj feem cuam tshuam. Txawm li cas los xij, qhov no txawv rau qhov loj-inch A269 316L stainless hlau raj, vim tias lawv cov dej tsis kam tsis siab npaum li hauv cov raj me me, ua rau lawv yooj yim dua rau cov neeg siv khoom siv thiab ntxuav. Yog li ntawd, cov kav dej me me 316L stainless hlau yog tsim rau cov kua dej huv, thaum loj-inch A316L stainless hlau kav yog tsim rau cov kua dej ntau dua los yog cov kua dej turbid.

Thaum tshav kub kub Exchanger Tube Test Method

Thaum lub sij hawm ua haujlwm ntev ntawm cov hlau tsis muaj steel hlau kub exchanger raj, cov kev sib tsoo yog feem ntau tshwm sim vim corrosion thiab yaig ntawm qhov nruab nrab, nrog rau hnav ntawm baffles lossis baffle daim hlau, uas tuaj yeem cuam tshuam rau kev nyab xeeb ntawm cov khoom siv siab. , ua rau kev kaw ib ntus thiab ua rau lub voj voog ua haujlwm luv luv ntawm chav tsev. Tsis tas li ntawd, cov dej xau kuj tseem tuaj yeem ua rau corrosion hauv lwm qhov chaw / khoom siv thiab cuam tshuam rau cov khoom zoo. Yog li ntawd, ntxiv dag zog rau kev saib xyuas thiab kev ntsuam xyuas ntawm corrosion nyob rau hauv stainless hlau tshav kub exchanger raj bundles yog ib qho tseem ceeb txhais tau tias kom muaj kev ruaj ntseg ntau lawm, nrog Internal Rotary Inspection System (IRIS) yog ib tug ntawm cov kev soj ntsuam txoj kev.

Introduction to IRIS Inspection Method:

Lub hauv paus ntsiab lus ntawm Internal Rotary Inspection System (IRIS) yog ua raws li ultrasonic pulse-echo nrhiav txoj kev. Lub transducer excites lub siab-frequency mem tes hauv dej los tsim ultrasonic tsis, uas yog reflected rov qab nyob rau hauv lub puab txoj kab uas hla ntawm lub raj los ntawm ib tug reflector.

Echoes tuaj yeem cuam tshuam los ntawm ob sab hauv thiab sab nrauv ntawm lub raj. Los ntawm kev xam, lub puab txoj kab uas hla, sab nraud txoj kab uas hla, thiab phab ntsa thickness ntawm lub raj yuav tau. Lub reflector yog tsav thiab tig ceev ceev los ntawm lub taub hau turbine, thiab ib qho kev sib hloov tuaj yeem ntes cov phab ntsa tuab ntawm lub voj voog ntawm cov cua kub sib txawv. Raws li qhov kev sojntsuam txuas ntxiv rov qab, tag nrho cov raj xa hluav taws xob tuaj yeem ntsuas tau, tsim cov duab intuitive.
