I. Cov yam ntxwv ntawm cov khoom: Lub corrosion kuj ntawm Hastelloy
alloy Hastelloy alloy, raws li tus neeg sawv cev ntawm nickel-raws li corrosion- alloys tiv taus, muaj cov ntsiab lus xws li npib tsib xee (Ni), chromium (Cr), thiab molybdenum (Mo). Los ntawm qhov sib piv ntawm cov alloy zoo, cov yeeb yaj kiab oxide tuab yog tsim, ua kom pom qhov zoo tshaj plaws corrosion kuj nyob rau hauv corrosive xov xwm xws li muaj zog acids, muaj zog hauv paus, thiab ntsev pos huab. Noj HC276 alloy ua piv txwv, nws cov ntsiab lus molybdenum siab li 15-17%, thiab nws cov ntsiab lus chromium yog 14-18%. Qhov kev sib xyaw ua ke ntawm molybdenum siab thiab siab chromium ua rau nws ruaj khov hauv kev txo cov kua qaub (xws li hydrochloric acid thiab sulfuric acid) thiab oxidizing acids (xws li nitric acid). Kev sim cov ntaub ntawv qhia tau hais tias nyob rau hauv ib tug 60 degree, 50% sulfuric acid tov, tus nqi corrosion ntawm HC276 tsuas yog 0.002mm / xyoo, ntau qis dua li ntawm 316L stainless hlau ntawm 0.5mm / xyoo.
Ntxiv nrog rau kev tiv thaiv corrosion, cov khoom siv kho tshuab ntawm Hastelloy alloys kuj zoo heev. Nws lub zog tensile tuaj yeem ncav cuag 690MPa, yield zog 310MPa, thiab elongation 40%, ua kom nws tswj cov qauv kev ntseeg siab nyob rau hauv siab. Nyob rau hauv marine engineering, HC276 alloy yeeb nkab fittings tiv thaiv ob qhov kev ntsuam xyuas ntawm ntsev pos huab corrosion thiab dej hiav txwv yaig, nrog rau kev pab cuam lub neej txog li 30 xyoo, uas yog 5-8 npaug ntawm cov pa roj carbon zoo tib yam.
II. Tus Qauv Tsim: Innovativee breakthroughs nyob rau hauv tus tsim ntawm adapter nrog txawv txawv txoj kab uas hla
1. Dual daim npav lub tes tsho sealing mechanism Ib txwm threaded kev sib txuas los yog cov pob qij txha welded yog qhov ua rau muaj kev pheej hmoo los ntawm kev kub siab, thaum daim npav lub tes tsho tsim ua tiav kev sib khi mus tas li los ntawm kev sib tshuam. Nws cov qauv tseem ceeb muaj lub cev txuas, lub tes tsho pem hauv ntej, lub tes tsho nram qab, thiab lub txiv ntoo:
Pem hauv ntej compression fittings:adopts 30℃conical nto tsim. Nyob rau hauv lub pre-tightening quab yuam ntawm cov txiv ntseej, nws txiav ntug sib npaug txiav rau hauv cov yeeb nkab phab ntsa, tsim thawj hlau sealing kab;
Tom qabcompression fittings:generates radial quab yuam los ntawm elastic deformation, nruj nreem clamping lub sab nrauv phab ntsa ntawm cov yeeb nkab, ua rau lub thib ob sealing kab;
Lub cev connector:lub conical nto thiab lub tes tsho daim npav koom tes los hloov axial quab yuam mus rau hauv radial sealing quab yuam, kom ntseeg tau tias qhov xau ntawm tsawg dua 0.01ml / min nyob rau hauv lub siab ntawm 10MPa.
Qhov kev sib khi dual no ua rau cov khoom sib txuas kom tswj tau qhov kev sib khi ua haujlwm txawm tias nyob rau hauv cov xwm txheej zoo xws li kev co thiab kev cuam tshuam. Cov ntaub ntawv los ntawm kev lag luam tshuaj qhia tau hais tias qhov kev sib khi tsis ua haujlwm ntawm lub raj xa dej siv HC276 daim npav lub tes tsho pob qij txha, tom qab ua haujlwm tas li rau 2 xyoos, tsuas yog 0.3%, qis dua 5% rau cov pob qij txha welded.
2. Kev ua haujlwm ntawm adapter nrog txoj kab uas hla sib txawv
Lub adapter nrog qhov sib txawv ntawm txoj kab uas hla paub txog ob txoj haujlwm ntawm cov yeeb nkab branching thiab txoj kab uas hla hloov los ntawm kev sib xyaw tsim. Txoj kev ntws tau txais qhov sib npaug ntawm - ntu ntu hloov pauv tsim, nrog rau ntu kev hloov mus ntev los ntawm cov yeeb nkab loj mus rau ceg yeeb nkab tswj hauv 1: 3, txo cov dej tsis kam. Nyob rau hauv ib txoj haujlwm marine platform, siv DN50 rau DN25 adapter pob qij txha txo qhov system siab poob los ntawm 0.8MPa rau 0.3MPa, uas ua rau ib xyoos twg cov nqi hluav taws xob txuag ntawm 120,000 yuan.
