Guud ahaan, dhexroorka tuubada waxaa loo qaybin karaa dhexroorka dibadda (De), dhexroorka gudaha (D), dhexroor magaceed (DN).
Hoos waxaan ku siin doonaa farqi u dhexeeya kuwan "De, D, DN".
DN waa dhexroorka magaca tuubada
Fiiro gaar ah: Tani maaha dhexroorka dibadda ama dhexroorka gudaha; waa in ay la xiriirtaa horumarinta hore ee injineernimada dhuumaha iyo cutubyada Imperial; inta badan waxaa loo isticmaalaa in lagu qeexo birta galvanized, taas oo u dhiganta cutubyada Imperial sida soo socota:
Tuubbada 4-qayb: 4/8 inch: DN15;
Tuubbada 6-daqiiqo: 6/8 inch: DN20;
1 tuubo inch: 1 inch: DN25;
Inji laba tuubo: 1 iyo 1/4 inji: DN32;
Dhuumaha nuska ah: 1 iyo 1/2 inji: DN40;
Tuubo laba inji ah: 2 inji: DN50;
Dhuumaha saddex-inji: 3 inji: DN80 (meelo badan ayaa sidoo kale lagu calaamadeeyay DN75);
Dhuumaha afar-inji: 4 inji: DN100;
Biyaha, birta gudbinta gaaska (Dhuumaha birta galvanizedama tuubo bir ah oo aan galvanized ahayn), tuubada birta ah ee shubka ah, birta-caag tuubo isku dhafan iyo tuubo polyvinyl chloride (PVC) iyo alaabada kale ee tuubooyinka, waa in lagu calaamadiyaa dhexroor magac ahaan "DN" (sida DN15, DN20).
De inta badan waxaa loola jeedaa dhexroorka dibadda ee tuubada
Isticmaalka guud ee calaamadaynta De, waxay u baahan tahay in lagu calaamadiyo qaabka dhexroorka dibadda X dhumucda derbiga;
Inta badan loo isticmaalo in lagu qeexo:tuubo bir ah oo aan lahayn, PVC iyo tuubooyinka kale ee caagga ah, iyo tuubooyinka kale ee u baahan dhumucdiisuna waxay caddahay.
Tusaale ahaan u soo qaado tuubo bir ah oo galvanized ah, oo leh DN, De two hababka calaamadaynta waa sida soo socota:
DN20 De25×2.5mm
DN25 De32×3mm
DN32 De40×4mm
DN40 De50×4mm
......
D guud ahaan waxa ay tilmaamaysaa dhexroorka gudaha ee tuubada, d waxa ay tilmaamaysaa dhexroorka gudaha ee tuubada shubka ah, iyo Φ waxa ay tilmaamaysaa dhexroorka goobada caadiga ah.
Φ sidoo kale waxay muujin kartaa dhexroorka dibadda ee tuubada, laakiin markaa waa in lagu dhufto dhumucda derbiga.
Tusaale ahaan, Φ25×3 macneheedu waa tuubo leh dhexroor ka baxsan 25mm iyo dhumucdiisuna tahay 3mm.
Dhuumaha birta ah ee aan xumi lahayn ama birta aan birta ahayn, waa in lagu calaamadiyaa "dhexroorka sare × dhumucda derbiga".
Tusaale ahaan: Φ107×4, halkaasoo Φ laga saari karo.
Shiinaha, ISO iyo qaybta Japan ee calaamadaynta tuubada birta iyadoo la adeegsanayo cabbirada dhumucda gidaarka si loo muujiyo dhumucda derbiga taxanaha birta. Noocaan tuubada birta ah, habka loo muujiyo tuubada ka baxsan dhexroor × dhumucda derbiga. Tusaale ahaan: Φ60.5×3.8
De, DN, d, ф ee kala duwan ee tibaaxaha!
De-- PPR, PE pipe, tuubooyinka polypropylene OD
DN -- tuubooyinka polyetylen (PVC), tuubada birta shubka ah, tuubo isku dhafan bir-caag ah, dhexroor magac ahaan bir galvanized
d -- dhexroorka tuubada shubka ah
ф -- dhexroor magaceedu yahay tuubo bir ah oo aan lahayn
