2. Abubuwan buƙatu na musamman don launukan bututun ƙarfe a cikin kasuwannin gida da na waje
(1) Kasuwar Sinanci (ma'aunin GB)
Magudanar Ruwa na Cast Iron Bututu: yawanci baki (kwalta anti-lalata) ko asalin baƙin ƙarfe launin toka, wani bangare mai rufi da epoxy guduro (kore).
Bututun Ƙarfe Mai Ba da Ruwa:Bututun ƙarfe na yau da kullun: baki ko ja (don kariya daga wuta).
Ductile Iron Pipe (DN80-DN2600): bangon waje wanda aka fesa da zinc + kwalta (baƙar fata), rufin ciki tare da ciminti ko resin epoxy (launin toka/kore).
Bututu Kariyar Wuta: shafi mai ja, daidai da ƙayyadaddun kariyar kariyar wuta na GB 50261-2017.
Bututun Gas: rawaya (amma bututun iskar gas na zamani galibi ana yin su ne da PE ko bututun ƙarfe, kuma ba a cika amfani da baƙin ƙarfe ba).
(2) Kasuwar Amurka (AWWA/ANSI Standard)
AWWA C151 (ductile iron bututu):
bangon waje: yawanci baki (shafin kwalta) ko azurfa (galvanized).
Rubutun ciki: turmi siminti (launin toka) ko guduro epoxy (kore/ shuɗi).
Bututun Kariyar Wuta (NFPA): tambarin ja, wasu suna buƙatar buga kalmomin "SERVICE WUTA" don bugawa.
Bututun Ruwa (Shaidar NSF/ANSI 61): rufin ciki dole ne ya dace da ka'idodin tsafta, babu wani abin da ake buƙata don launin bango na waje, amma ana amfani da tambarin kore ko shuɗi sau da yawa.
(3) Kasuwar Turai (EN misali)
TS EN 545 / EN 598 bututu baƙin ƙarfe
Anticorrosion na waje: zinc + kwalta (baƙar fata) ko polyurethane (kore).
Rufin ciki: turmi siminti ko resin epoxy, babu ƙaƙƙarfan ƙa'idodin launi, amma dole ne ya bi ka'idodin ruwan sha (kamar takardar shedar KTW).
Bututun Wuta: ja (wasu ƙasashe suna buƙatar bugu "FEUER" ko "WUTA").
Bututun Masana'antu: na iya zama shuɗi (matsewar iska) ko rawaya (gas, amma an maye gurbin bututun ƙarfe a hankali).
(4) Kasuwar Jafananci (JIS misali)
JIS G5526 (ductile iron bututu): Bangon waje yawanci baki ne (kwalta) ko galvanized (azurfa), kuma rufin ciki shine siminti ko guduro.
Bututun wuta: zanen ja, wasu suna buƙatar bugu "yaƙin wuta".
Bututun ruwan sha: kore ko shuɗi mai rufi, daidai da ma'aunin JHPA.
3. Tasirin launi na kayan shafa na musamman na anti-lalata
Epoxy resin shafi: yawanci kore ko shuɗi, ana amfani da shi don manyan buƙatun hana lalata (kamar ruwan teku, masana'antar sinadarai).
Rufin polyurethane: na iya zama kore, baki ko rawaya, tare da juriya mai ƙarfi.
Zinc + kwalta shafi: bangon waje na baki, dace da bututun binne.
4. Takaitawa: Yadda za a zabi launi na simintin ƙarfe na ƙarfe?
Zaɓi ta amfani:
Magudanar ruwa / najasa → baki/ launin toka
Ruwan sha → kore/blue
Yin kashe gobara → ja
Masana'antu → ta matsakaicin ganewa (kamar gas mai launin rawaya, iska mai shuɗi)
Zaɓi bisa ma'auni:
China (GB) → baki (magudanar ruwa), ja (fashin kashe gobara), kore (ruwa mai sha)
Turai da Amurka (AWWA/EN) → baƙar fata (maganin lalata na waje), kore/ shuɗi (rufi)
Japan (JIS) → baki (bangon waje), ja (fashin wuta)
Idan har yanzu ba ku san yadda ake zaɓe ba, da fatan za a tuntuɓi DINSEN
