2. Litlhoko tse khethehileng bakeng sa mebala ea phala ea tšepe e entsoeng ka tšepe limmarakeng tsa malapeng le tsa linaheng tse ling
(1) Mmaraka oa China (GB standard)
Drainage Cast Iron Pipes: hangata e ntšo (asphalt anti-corrosion) kapa tšepe ea mantlha ea bohlooho, e koahetsoeng ka karolo e itseng ka epoxy resin (e tala).
Phepelo ea Metsi Lahlela Pipe ea Tšepe:Pipe ea tšepe e tloaelehileng: e ntšo kapa e khubelu (bakeng sa tšireletso ea mollo).
Ductile Iron Pipe (DN80-DN2600): lebota le ka ntle le fafalitsoeng ka zinki + asphalt (e ntšo), lesela le ka hare le nang le samente kapa epoxy resin (ea bohlooho / botala).
Pipe ea Tšireletso ea Mollo: ho roala bofubelu, tumellanong le tlhaloso ea tšireletso ea mollo ea GB 50261-2017.
Pipe ea Khase: e mosehla (empa liphaephe tsa kajeno tsa khase hangata li entsoe ka PE kapa lipeipi tsa tšepe, 'me tšepe e entsoeng ka tšepe ha e sebelisoe hangata).
(2) Mmaraka oa US (AWWA/ANSI Standard)
AWWA C151 (peipi ea tšepe ea ductile):
Lerako la ka ntle: hangata e ntšo (sekontiri sa asphalt) kapa silevera (sekontiri).
Lesela la ka hare: seretse sa samente (bohlooho) kapa resin ea epoxy (e tala / e putsoa).
Pipe ea Tšireletso ea Mollo (tekanyetso ea NFPA): letšoao le khubelu, tse ling li hloka hore mantsoe a "FIRE SERVICE" a hatisoe.
Pipe ea Metsi a Noang (Setifikeiti sa NSF / ANSI 61): lesela le ka hare le tlameha ho finyella litekanyetso tsa bohloeki, ha ho na tlhokahalo e tlamang bakeng sa 'mala o ka ntle oa lerako, empa hangata ho sebelisoa logo e tala kapa e putsoa.
(3) Mmaraka oa Europe (EN maemo a tloaelehileng)
EN 545/EN 598 (peipi ea tšepe ea ductile):
External Anticorrosion: zinki + asphalt (e ntšo) kapa polyurethane (e tala).
Inner Lining: seretse sa samente kapa resin ea epoxy, ha ho na melao e thata ea mebala, empa e tlameha ho lumellana le litekanyetso tsa metsi a nooang (joalo ka setifikeiti sa KTW).
Pipe ea Mollo: e khubelu (linaha tse ling li hloka ho hatisoa "FEUER" kapa "FIRE").
Pipe ea indasteri: e ka 'na ea e-ba putsoa (moea o hatelitsoeng) kapa mosehla (khase, empa liphaephe tsa tšepe tse entsoeng ka tšepe li fetotsoe butle-butle).
(4) Mmaraka oa Japane (JIS standard)
JIS G5526 (peipi ea tšepe ea ductile): Lerako le ka ntle hangata le ntšo (asphalt) kapa galvanized (silevera), 'me lesela le ka hare ke samente kapa resin.
Pipe ea mollo: penta e khubelu, tse ling li hloka ho hatisa "ntoa ea mollo".
Pipe ea metsi a nooang: lesela le letala kapa le leputsoa, ho latela maemo a JHPA.
3. Tšusumetso ea 'mala oa liaparo tse khethehileng tsa anti-corrosion
Epoxy resin coating: hangata e tala kapa e putsoa, e sebelisetsoang litlhoko tse phahameng tsa ho thibela ho bola (joaloka metsi a leoatle, indasteri ea lik'hemik'hale).
Ho roala ha polyurethane: e ka ba e tala, e ntšo kapa e mosehla, e nang le khanyetso e matla ea leholimo.
Zinc + sekontiri sa asphalt: lerako le ka ntle le letšo, le loketseng liphaephe tse patiloeng.
4. Kakaretso: Joang ho khetha 'mala oa liphaephe tsa tšepe tse entsoeng ka tšepe?
Khetha ka tšebeliso:
Mokelikeli / likhoerekhoere → botšo / bohlooho
Metsi a nooang → tala/putsoa
Litima-mollo → bofubelu
Indasteri → ka boitsebahatso ba mahareng (joalo ka khase e tšehla, moea o hatelitsoeng o moputsoa)
Khetha ho ea ka maemo:
China (GB) → e ntšo (drainage), e khubelu (ea ho tima mollo), e tala (metsi a nooang)
Europe le United States (AWWA/EN) → e ntšo (e thibelang ho bola ka ntle), botala/putsoa (lesela)
Japane (JIS) → e ntšo (lebota le ka ntle), e khubelu (ea tima mollo)
Haeba o ntse o sa tsebe ho khetha, ka kopo ikopanye le DTS'ELISO
