Cov lus pom zoo rau kev txhim kho cov hlau stainless hlau hoses
Tswv yim 1. Vuam zoo
Thaum lub sij hawm vuam txheej txheem, corrugated kav, rings reinforcing thiab steel mesh lub tes tsho yog nquag welding tsis tseeb ntawm cov hlau hlau (overheated los yog tsis welded). Thaum lub hose raug ntsia rau hauv lub raj xa dej, vim qhov tsis sib xws ntawm cov hlau xaim hlau, nyob rau hauv qhov kev txiav txim ntawm qhov nruab nrab siab, qhov tsis sib xws vuam tshwm sim. Kev rub tawm cov vuam hlau yuav ua rau muaj kev puas tsuaj rau lub nruas sab nraud ntawm lub tshuab raj.
Qhov tsis xws luag xws li vuam tsis muaj zog, qhov pores, xoob dendrites thiab lwm yam tsis xws luag nyob rau hauv lub longitudinal welds ntawm corrugated kav nyob rau hauv stainless hlau hoses txo qhov zoo ntawm lub hauv paus phab ntsa thickness, thiab tsis txaus lub zog ua rau tawg thiab puas ntawm cov welds. Kev sib txuas ntawm cov khoom siv carbon steel thiab stainless hlau qhov chaw tsim ib qho chaw tsis zoo nyob qhov twg ib cheeb tsam me me ntawm cov txiv neej qhov chaw thiab thaj chaw loj ntawm cov poj niam nyob rau hauv kev sib cuag, uas tuaj yeem yooj yim ua rau corrosion sai thiab tsis ua hauj lwm ntawm cov khoom. Yog li ntawd, peb yuav tsum ntxiv dag zog rau cov txheej txheem vuam kev tshawb fawb thiab kev xaiv cov khoom siv vuam, thiab ntxiv dag zog rau kev tshuaj xyuas zoo los txhim kho cov khoom lag luam.
Tswv yim 2. Mechanical processing
Vim tsis muaj kev ntxhov siab thaum lub sij hawm corrugation txheej txheem, cov khoom yog nquag tsim micro-cracks nyob rau hauv lub puab nto ntawm lub ncov yoj. Thaum lub sij hawm vuam thiab tsim cov txheej txheem, micro-cracks tshwm sim nyob rau sab hauv ntawm lub hose. Thaum lub sij hawm sib dhos tom ntej thiab thaum siv, microcracks yuav ua rau qaug zog nthuav dav thiab tom qab ntawd ua tsis tiav. Kev txhim kho hauv cov khoom siv thiab cov txheej txheem vuam tuaj yeem zam qhov tshwm sim ntawm microcracks.
Tswv yim3. Kev kho cua sov
Lub luag haujlwm tseem ceeb ntawm kev kho cua sov rau cov hlau tsis muaj steel hlau hoses yog: txhim kho kev ua haujlwm ntawm kev txiav thiab kev ua tiav ntawm cov ntaub ntawv hlau; txhim kho cov pob txha toughness ntawm cov ntaub ntawv hlau; thiab txo qhov tawg ntawm cov khoom siv hlau. Yog tias qhov kev kho cua sov tsis tiav, cov khoom zoo yuav raug cuam tshuam.
Cov saum toj no yog cov lus qhia cuam tshuam rau kev ua cov hlau stainless hlau hoses. Kuv vam tias cov ntsiab lus saum toj no yuav pab tau koj.
