one、Inches It is a phyttal called a nominal diameter to change to a millimeter, which can only be a nominal diameter.,Can't correspond,Because the same nominal diameter tube has a size diameter

two、There is no absolute conversion formula in the specifications of the pipeline,For less than100Can only1Inches=25 Caution,Take a similar number,For greater than100Pipe1Inches=25Fully match calculation。Commonly used:

1、DN(Nominal Diameter)Means the nominal diameter of the pipe,Is the average of outer diameters and inner diameter。DNValue=DeValue-0.5*Tube wall thickness。Notice:This is neither an outer diameter is not an inner diameter。

water、Gas conveying steel pipe(Galvanized steel pipe or non-galvanized steel pipe)、Cast iron pipe、Steel-plastic composite pipe and polyvinyl chloride(PVC)Pipe and other pipe,Named diameter“DN”(Such asDN15、DN50)。

2、De(External Diameter)Means the outer diameter of the pipe,PPR、PETube、Polypropylene tube outer diameter,Generally adoptedDeLabeled,Need to mark the outer diameter*Wall thick form,exampleDe25×3。

3、DGenerally refers to the inner diameter of the pipeline。

4、dGenerally refers to the diameter of the concrete tube 。RC(Concrete)Tube、Clay tube、Acid-resistant ceramic tube、Cylinder tube and other pipes,The pipe is suitable for an inner diameterdExpress(Such asd230、d380Wait)。

5、ΦRepresents the diameter of ordinary circle;It can also represent the outer diameter of the pipe.,But at this time, it should be multiplied by the wall.。Such as:Φ25×3,Outer diameter25mm,Wall thickness3mmPipe。Seamless steel pipe or colored metal pipeline,Be labeled“Outer diameter×Wall thickness”。E.gΦ108×4,ΦMay omit。China、ISOAnd some steel pipe standards in Japan use wall thickness to represent steel tube wall thickness series。The representation of such steel pipe specifications is the outer diameter of the tube×Wall thickness。E.gΦ60.5×3.8。
