Generally,The diameter of the tube can be divided into outer diameter、the inside diameter of、Nominal diameter。

The pipe is used for the outer diameter of the tube seamless steel pipeDTo represent,The size and wall thickness of additional diameter,For example, the outer diameter is108Seamless steel pipe,Wall thickness5MM,useD108*5Express。

Plastic tube also expressed the outer diameter,Such asDe63。

(8 inch diameter brass tube)Other reinforced concrete tubes、Cast iron pipe、Galvanized steel pipe, etc.DNExpress。

Generally adopted a nominal diameter in design drawings.,Nominal diameter is a standard for designing manufacturing and maintenance to facilitate manual provisions,Also compared with nominal,Be a pipe(Or fitting)Specification name。

Nominal diameter and its inner diameter of the pipe、The outer diameter is not equal,E.g:Nominal diameter is100MMSeamless steel pipe102*5、108*5Have a few kinds of,108Outer diameter of the pipe,5Indicate the wall thickness of the pipe,therefore,The inner diameter of the steel pipe is(108-5-5)=98MM,However, it is not completely equal to the difference between the outer diameter of the steel pipe.,Also known as,Nominal diameter is close to the inner diameter,But not equal to a specification name of a pipe diameter of the inner diameter,In the design drawings, use a nominal diameter,The purpose is to determine the pipe according to the nominal diameter.、Fitting fitting、valve、Flange、Signment and other structural dimensions and connection sizes,Nominal diameter adopt symbolDNExpress,If the outer diameter is used in the design drawings,Pipeline specifications should also be made,Indicates a nominal diameter of some kind of pipeline,Wall thickness。

(In fact, there is no complete pipeline nominal diameter and outer diameter of the engineering field.,External diameter and nominal diameter conversion is basically experienced。

It is approximately a diameter of the nominal diameter equal to the inner diameter(Thick outer diameter)

But not completely equal,Roughly almost,Hit。for exampleφ108*7Outer diameter108,Its nominal diameter is100;Another exampleφ32*4.5,Outer diameter32,Nominal diameter should be25。Push,You can get the corresponding relationship between the outer diameter and the nominal diameter.。)
