Waya ma jukunyo ku cuma ma jukubo ku cing: nyang ikum tic migi, tic migi man yero migi.
Waya mi cuma, calu piny ma pire tek mi tingo pek man mi cwalo piny, jutiyu kudu lee i tic mi gedo, tero piny, tic mi nam, man tic mi yubu piny. Ikind kit mapol, Waya mi cuma ma jukubo ku galvanizeds man stainless steel wire ropes gibedo piny ario ma juporo i yero piny mi gedo pi bedo migi ma ukoc ku kero migi mi juku lyethu man kite migi mi tic. Lembe maeni bi mio nen pa lembe ario eni kud i thenge matung tung, ikinde utiye ngec mi piny, kite pa cuma, yore mi juku lyethu, man lim, man bi mio paru ikum yero piny.
I. Piny ma jutiyo kudu man kit ma jugwoku kudu kud i lyethu
1. Waya ma juyiko ku cuma
Kit piny ma jutiyo kudu: Cuma ma dwong pa carbon calu piny ma pire tek, juyike ku zinc maleng nyo zinc-iron alloy nikadhu kud i hot-dip galvanizing nyoke electro-galvanizing.
Yore mi gwoko kum: Zinc layer juku carbon steel ma piny ni nyai nikadhu kud i anode protection mechanism. Ka wire rope unyothere man piny ma iye wok woko, reactive zinc timo tic calu anode, ma gwoko iron (cathode) ma tiyo ngo.
Kit tic:
Gwok pa Corrosion: Ber, ucungo maber ikum oxidation man moisture i kabedu mi polo.
Peko: Layer pa zinc utiye nok. I chloride (macalu pii nam) nyo kabedo ma acid/alkali tek, dul pa zinc jucamu nyathotho. Ka dong ethum, cuma ma piny eca bi nyai pio pio.
2. Waya mi cuma ma nyai
Kit piny ma jutiyo kudu: Pol kare austenitic stainless steel. Grade ma pol kare jutiyo kudu uketho i iye:
AISI 304: Utie ku 18% chromium man 8% nickel, maber pi kabedo ma nyai. AISI 316: Utie ku chromium, nickel, man molybdenum (Mo).
Yore mi gwoko kum: Chromium (Cr) in stainless steel timo tic ku oxygen i yamu nyo pii mi yubu piny ma nyap, ma pek, man ma nen maleng ma chromium-rich oxide passivation film iwi ngom. Filim eni utiye ku kemikol ma tek man ecopo keyo gire gire, eno uketho egwoko oxidation man corrosion pa steel substrate.
Kit tic:
Gwok pa Corrosion: Ber akecha. Mapire tek 316 stainless steel (marine grade), pi medu pa molybdenum, umedire lee dit i kum pitting corrosion man crevice corrosion, timo maber akeca i nam man i kabedo mi kemikol.
Peko: Bei madit, man stress corrosion cracking (SCC) copo timere asu i kabedu ma chloride lyeth lee i iye.
II. Poro pa kit pa cuma man kit pa olo
1. Teko mi ngwec
Thol ma juyiko ku galvanized: Piny ma pire tek ubedo steel ma julwongo ni cold-drawn high-carbon steel, ma tek mandha. Teko pare mi turo piny ubedo malo uloyu pa thung ma nyali ma nyai ma rwom pare rom.
Thol ma nyali ma nyai: Austenitic stainless steel (304/316) copo bedu ku tego madit ingey tic ma ngic, ento pol kare etiye piny nyanok ni rwom pa waya mi steel ma rwom pare rom. Ento, i thenge moko mi lyethu nyo kabedo moko, thwol mi stainless steel bedu ku tego maber.
2. Tic mi olo
Kwo mi olo ubedo lanyuth madit pa kero pa waya mi cuma.
Thol ma juyiko ku galvanized: Lembe mi galvanizing copo loko kit ma iye pa waya mi cuma, ento i rwom ma malu, tic pare mi olo ber. Ento, zinc layer copo nyai i the telowic high-stress friction, ma medu corrosion mi iye man edwoko kwo pa fatigue piny.
Thol ma nyali ma nyai: I kabedu ma nyai ungo, kwo pare mi olo rom ku pa thwol ma tek. I kabedu ma nyai, stainless steel juku nyai pa microcracks i waya mi cuma pi nyai, ma kelo kwo ma lee dit mi nyai ma sagu waya mi cuma ma galvanized.
III. Cik mi yero jam tic man paru mi tic kudu
Lembe mi yero piny ma jutiyo kudu ucikere ni bedu lembe ma rwate ikind tic, kabedu, kwo, man wel piny.
1. Pima pa nyoth pa piny (piny ma pire tek)

2. Lembe mi gedo man mi gwoko
Gwoko: Twol mi stainless steel mito ngo yub maber ikabedu ma rac, ma dwoko piny wel piny ma jucwalo (TCO).
Teko ma mitere: Ka tic ne utiye ku piny ma mitere pi tego ma lac man kero ma nok mi juku nyoth, waya ma tek ma galvanized steel ucikere ni bedu piny mir acel.
Kit tic:
Tingo man tingo: Waya ma tek ma julwongo ni galvanized steel wire ropes jutiyo kudu pol kare, ma weko bedo ber, tego pa turo, man bedo ku lim.
Ribing man waya (e.g., lum, kabedo mi nam): Malu Waya mi cuma ma nyai ungo thwol umitu jutii kudu, ma ketho cwiny ikum bedo maber pa ot man gwoko piny ma nok.
3. Nyamu lembe mi lim
Kadi bende wel mi wil pa waya mi cuma ma jukubotho ubedo piny uloyu wel pa waya mi stainless steel (ma pol kare ubedo wel ma nok), i kabedu ma nyai, thol mi galvanized copo kwayu julok kare ku kare, ma kelo wel ma malu (ma uketho i iye wil, loko, man kare mi thum) ka juporo ku stainless steel rope. Pieno, **life cycle cost analysis (LCC)** umaku jutii kudu pi nwangu yore mi timo piny.
Ajiki
Galvanized steel wire rope ubedo piny ma tiyo ku yore madwong man ma wel pare lapiny maber pi kabedo mi tic man kabedo mi yamo, ma nyutho tego man wel piny ma yot. Waya mi stainless steel, ku cing makende, ubedo piny ma tiyo maber ma juyike pi jwigo kabedo ma rac, ma weko ebedo piny ma pire tek ma jucopo yero, asaga i tic mi gedo mi nam, tic mi kemikol, yubu cam, man tic ma mitu bedo maber man leng. Jurudiro ucikere ni yero piny maber loyo nimakere ku lembe ma jutimo ikum kabedu, yeny pa cuma, man wel piny ma jutiyo kudu pi kwo.
