Ruvara rwemapaipi esimbi akakandwazvinowanzoenderana nekushandiswa kwadzo, kurapwa kwengura kana mwero weindasitiri. Nyika dzakasiyana nemaindasitiri zvinogona kunge zvine zvinodiwa kuti mavara ave nechokwadi chekuti akachengeteka, haapindi ngura kana kuti zviri nyore kuziva. Izvi zvinotevera kupatsanurwa kwakadzama:
1. Zvinorehwa neDINSEN SML Pipe color
·Dema/grey dema/Simbi yekutanga kana asphalt/chifukidziro chekudzivirira ngura Kudhonza mvura, tsvina, mapaipi emuguta
·Tsvuku/Mapaipi emoto, kudzivirira kupisa kwakanyanya kana zviratidzo zvakakosha/Sisitimu yemoto, mvura ine simba rakawanda
·Girinhi/Mapaipi emvura yekunwa, machira asingakuvadzi nharaunda (akadai se epoxy resin)/Mvura yepombi, mvura yepamusoro yechikafu
·Bhuruu/Mvura yemumaindasitiri, mhepo yakamanikidzwa/Fekitori, sisitimu yemhepo yakamanikidzwa
·Yero/Mapaipi egasi (simbi shoma, akawanda mapombi esimbi)/Kutapurirana kwegasi (dzimwe nzvimbo dzichiri kushandisa simbi yakakandwa)
·Sirivha/Kurapa kwekudzivirira ngura kwakakandwa/Kunze, nzvimbo ine hunyoro, zvinodiwa zvakanyanya zvekudzivirira ngura
2. Zvinodiwa zvakakosha zvemavara epombi yesimbi yakakandwa mumisika yemuno neyekunze
(1) Musika wekuChina (GB standard)
Mapaipi eSimbi Yakagadzirwa Nesimbi: kazhinji kacho matema (asphalt anti-corrosion) kana simbi yepakutanga grey, yakafukidzwa zvishoma ne epoxy resin (girini).
Pombi yesimbi yakakandwa yemvura:Pombi yesimbi yakajairika: nhema kana tsvuku (yekudzivirira moto).
Ductile Iron Pipe (DN80-DN2600): madziro ekunze akapfapfaidzwa ne zinc + asphalt (dema), mukati memadziro nesimende kana epoxy resin (grey/green).
Pombi yekudzivirira moto: pendi tsvuku, inoenderana nezvinodiwa zvekudzivirira moto zveGB 50261-2017.
Pombi yeGasi: yero (asi pombi dzegasi dzemazuva ano dzinonyanya kugadzirwa nemapombi ePE kana esimbi, uye simbi yekukanda haiwanzo shandiswa).
(2) Musika wekuUS (AWWA/ANSI Standard)
AWWA C151 (pombi yesimbi inopfapfaidzwa):
Rusvingo rwekunze: runowanzova rutema (asphalt coating) kana sirivha (yakaiswa galvanized).
Mukati mejira: simende yakanyungudutswa (grey) kana epoxy resin (girini/bhuruu).
Pipe yekudzivirira moto (NFPA standard): chiratidzo chitsvuku, zvimwe zvinoda kuti mashoko ekuti "FIRE SERVICE" adhindwe.
Pombi yemvura yekunwa (NSF/ANSI 61 certification): jira remukati rinofanira kusangana nezvinodiwa nehutsanana, hapana chinodiwa kuti ruvara rwekunze rwemadziro ruve rwakachena, asi logo yegirini kana yebhuruu ndiyo inowanzo shandiswa.
(3) Musika weEurope (EN chiyero)
EN 545/EN 598 (ductile iron pombi):
Kudzivirira ngura kwekunze: zinc + asphalt (nhema) kana polyurethane (girini).
Inner Lining: simende kana epoxy resin, hapana mitemo yakasimba yeruvara, asi inofanira kutevedzera mitemo yemvura yekunwa (yakadai seKTW certification).
Pombi yemoto: tsvuku (dzimwe nyika dzinoda kudhindwa kuti “FEUER” kana kuti “FIRE”).
Mapaipi eIndasitiri: anogona kunge ari ebhuruu (mhepo yakamanikidzwa) kana eyero (gasi, asi mapaipi esimbi yakakandwa akatsiviwa zvishoma nezvishoma).
(4) Musika wekuJapan (JIS chiyero)
JIS G5526 (pombi yesimbi yakapfava): Rusvingo rwekunze runowanzova rutema (asphalt) kana kuti galvanized (sirivha), uye mukati memukati i simende kana resin.
Pombi yemoto: pendi tsvuku, mimwe inoda kudhindwa "kudzima moto".
Pombi yemvura yekunwa: jira regirini kana rebhuruu, zvinoenderana neJHPA standard.
3. Simba reruvara rwemachira akakosha ekudzivirira ngura
Kuvhara resin resin: kazhinji girini kana bhuruu, inoshandiswa pakudzivirira ngura zvakanyanya (senge mvura yegungwa, indasitiri yemakemikari).
Kupfeka kwepolyurethane: kunogona kuva kwegirini, dema kana yero, uye kunodzivirira mamiriro ekunze zvakanyanya.
Zinc + asphalt coating: madziro matema ekunze, akakodzera mapaipi akavigwa.
4. Pfupiso: Ungasarudza sei ruvara rwemapaipi esimbi yakakandwa?
Sarudza nekushandisa:
Kudhonza/tsvina → dema/grey
Mvura yekunwa → girini/bhuruu
Kudzima moto → tsvuku
Indasitiri → kuburikidza nekuziva zviri pakati nepakati (senge gasi yeyero, mweya wakamanikidzwa webhuruu)
Sarudza nechiyero:
China (GB) → dema (mvura inoyerera), tsvuku (kudzima moto), girini (mvura yekunwa)
Europe neUnited States (AWWA/EN) → dema (rinodzivirira ngura kunze), girini/bhuruu (rinofukidza)
Japan (JIS) → dema (rusvingo rwekunze), tsvuku (kudzima moto)
Kana uchiri kusaziva kusarudza, ndapota taura naDINSEN
