Kazhinji kutaura, dhayamita yepombi inogona kukamurwa kuita dhayamita rekunze (De), mukati dhayamita (D), zita rekuti dhayamita (DN).
Pazasi kuti ndikupe mutsauko pakati peiyi "De, D, DN" mutsauko.
DN ndiyo dhayamita yezita repombi
Cherechedza: Iyi haisi dhayamita yekunze kana dhayamita yemukati; inofanira kunge ine hukama nekutanga kuvandudzwa kwepombi engineering uye emperial units; inowanzo shandiswa kurondedzera galvanized simbi pombi, iyo inoenderana nemumambo zvikamu zvinotevera:
4-chikamu pombi: 4/8 inch: DN15;
6-miniti pombi: 6/8 inch: DN20;
1 inch pombi: 1 inch: DN25;
Masendimita maviri pombi: 1 uye 1/4 inches: DN32;
Half-inch pipe: 1 uye 1/2 inches: DN40;
Masendimita maviri pombi: 2 inches: DN50;
Tatu-inch pombi: 3 inches: DN80 (nzvimbo dzakawanda dzinonziwo DN75);
Ina-inch pipe: 4 inches: DN100;
Mvura, gasi kutapurirana simbi pombi (galvanized steel pipekana pombi yesimbi isina-galvanized), pombi yesimbi yakakandwa, simbi-yepurasitiki inoumba pombi uye polyvinyl chloride (PVC) pombi nezvimwe zvinhu zvepombi, zvinofanirwa kunyorwa nedhayamita rezita "DN" (senge DN15, DN20).
De kunyanya inoreva kureba kwekunze kwepombi
Kushandiswa kwakazara kweDe labeling, inoda kunyorwa muchimiro chekunze kwedhayamita X ukobvu hwemadziro;
Inonyanya kushandiswa kutsanangura:pombi yesimbi isina musono, PVC nemamwe mapaipi epurasitiki, uye mamwe mapaipi anoda kujeka kwemadziro ukobvu.
Tora galvanized welded simbi pombi semuenzaniso, neDN, De nzira mbiri dzekunyora ndedzinotevera:
DN20 De25×2.5mm
DN25 De32×3mm
DN32 De40×4mm
DN40 De50×4mm
......
D kazhinji inoreva dhayamita yemukati yepombi, d inoratidza dhayamita yemukati yepombi yekongiri, uye Φ inoratidza dhayamu redenderedzwa rakajairika.
Φ inogonawo kuratidza dhayamita yekunze yepombi, asi zvino inofanira kuwanda nehupamhi hwemadziro.
Semuenzaniso, Φ25×3 zvinoreva pombi ine dhayamita yekunze ye25mm uye ukobvu hwemadziro hwe3mm.
Seamless simbi pombi kana non-ferrous simbi pombi, inofanira kunyorwa "kunze dhayamita × rusvingo ukobvu".
Semuenzaniso: Φ107×4, apo Φ inogona kusiiwa.
China, ISO neJapan chikamu chesimbi pombi yakanyorwa kushandisa madziro makubvu dimensions kuratidza kukora kwemadziro esimbi pombi dzakatevedzana. Kune rudzi urwu rwepombi yesimbi, nzira yekutaura kwepombi kunze kwedhayamita × rusvingo ukobvu. Somuenzaniso: Φ60.5×3.8
De, DN, d, ф yehuwandu hwekutaura!
De-- PPR, PE pombi, polypropylene pombi OD
DN -- polyethylene (PVC) pombi, pombi yesimbi yakakandwa, simbi-yepurasitiki inoumbwa pombi, galvanized simbi pombi dzinonzi dhayamita
d -- kongiri pombi nominal dhayamita
ф -- musono simbi pombi nominal dhayamita
Nguva yekutumira: Jan-10-2025
