Generaliter loquendo, diametrum pipe potest dividi in exterior diameter (de), interior diameter (d), nominis diameter (Dn).
Infra dabo vobis distinctionem inter haec "de, D, DN" differentia.
DN est nominis diameter de pipe
Nota quod nec extra diameter nec intra diameter; sit ad primis progressionem Pipeline Engineering et imperatoria unitates; Plerumque solebat describere galvanized ferro tibia, quae correspondet imperialium unitates ut sequitur:
IV-Part Pipe: 4/8 inch: DN15;
VI-minute pipe: 6/8 inch: Dn20;
I inch pipe: I inch: DN25;
Inch duo pipe: I et 1/4 pollices: Dn32;
Half-inch Pipe: I et 1/2 pollices: DN40;
Duo inch pipe: II pollices: Dn50;
Three-inch pipe: III pollices: Dn80 (multis locis etiam intitulatum quod DN75);
Quattuor inch pipe: IV pollices: DN100;
Aqua, Gas Transmissus ferro pipe (galvanized ferro pipeaut non-galvanked ferro pipe), mittent ferrum fistulam, ferro, plastic compositum pipe et polyvinyl chloride (PVC) pipe et alia pipe materiae, ut sit notatum diameter "DN20).
De maxime refertur ad exterior diameter pipe
General usu de labeling, opus ad esse intitulatum in forma exterior diameter x murum crassitudine;
Maxime solebat describere:Seamless ferro pipePMC et alii plastic fistulae et aliisque fistulae requirere clarum murum crassitudine.
Take galvanized Steel fistula ut exemplum, cum DN, De duobus labeling modi sunt, ut sequitur:
DN20 DE25 × 2.5mm
DN25 D32 × 3mm
DN32 DE40 × 4mm
DN40 DE50 × 4mm
......
D plerumque refert ad interiorem diametrum pipe, D indicat interiore diameter de concreto pipe, et φ indicat diameter Ordinarius circulo
Φ potest etiam indicare exterior diameter tibia, tunc ergo debet multiplicari per murum crassitudine.
Exempli gratia, φ25 × III significat tibia cum extra diameter 25mm et murum crassitudine 3mm.
Seamless ferro pipe vel non-ferrea metallum pipe, notatur "exterior diameter × murum crassitudine."
Exempli gratia: φ107 × IV, ubi φ potest omittenda.
Sinis, iso et Iaponia scriptor pars ferro pipe labeling per murum crassitudine dimensiones indicant murum crassitudine ferro pipe seriem. Type ferro pipe modum exprimendi fistula extra diameter × murum crassitudine. Exempli gratia: φ60.5 × 3.8
De, DN, D, ф de respective range ex expressione!
De-- PPR, pe pipe, Polypropylene pipe Od
DN - Polyethylene (PVC) Pipe, Ferrum Ferrum Pipe, Steel-plastic compositum pipe, galvanized ferro pipe nomina diameter
D - concretum pipe nominis diameter
ф - seamless ferro pipe nominis diameter
