Calculate units of welding work,That is, welding equivalents。Foreign name,A diameter1One weld in inch is1Welding(1Daty)。10indivual1Inch's weld is10Daty,2indivual5Inch weld is also10Daty,This statistical method only considers the influence of the weld port diameter.,So only apply to the wall thickness8Welding of millimeters or less;Exceed8Mime increases every increase2Millimeter plus one0.1Coefficient。

Welding equivalents are nominal size with pipe inch(NPS-Nominal Pipe Size )Described pipe welding engineering。The welding equivalent of the unit pipe welding is the number of inch nominal size of the pipe.。


E.g:Pipe inch Name size is4 inch(NPS 4),welding1Tao weld weld,Welding equivalent 4 Dia-inch(Inch);welding2Trapping,Welding equivalent2*4=8 Dia-inch(Inch)。


Nominal pipe size(Nominal pipe diameter)Is a dimensionless indicator,exist“British unit”middle,It is also known as“Inch Nominal Size”;exist”Metric unit“middle,Also known as”Nominal diameter(DN-Nominal Diameter)。


The two units are commonly used in nominal pipeline sizes as follows:

Pipeline engineering is based on total welding equivalents(Progress management,Welder and pipe workers and welder configuration、Construction team work quota and fend management,Pipeline construction cost management, etc.),


Welding equivalents also need to integrate the interface of pipe welding ports(Docking welding,Saddle welding port,Insertion angle welding port,Thread seal welding port,Reinforcing plate welding, etc.),Pipe wall thickness,Material,Non-destructive detection ratio,Effect of factors such as pressure level on welding engineering。

one、De、DN、d、φMeaning

(brass tube 1 inch)

Generally,The diameter of the tube can be divided into outer diameter(De)、the inside diameter of(D)、Nominal diameter(DN)。


1、DNRefers to the nominal diameter of the pipeline,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、DeMainly refers to the outer diameter of the pipeline,PPR、PETube、Polypropylene tube outer diameter,Generally adoptedDeLabeled,Need to mark the outer diameter x Wall thick form,exampleDe25 x 3;


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


4、dConcrete pipe diameter。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 asφ25 x 3,Outer diameter25mm,Wall thickness3mmPipe。Seamless steel pipe or colored metal pipeline,Be labeled“Outer diameter x Wall thickness”。E.gφ108 x 4,φMay omit。

(brass tube 1 inch)

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 x Wall thickness。E.gφ60.5 x 3.8;


6、DNforNominal diameterMeans a nominal diameter;

(brass tube 1 inch)

7、Deforexternal diameterMeans the outer diameter;


8、Dgdiametergong(Chinese Pinyin“male”Parent)You will understand this.,DgCountry product goods,Domestic goods with Chinese characteristics,No need now。



two、Forming method of pipe diameter


1、water、Gas conveying steel pipe(Galvanized or non-galvanized)、Cast iron pipe and plastic pipe,Named diameter“DN”(Such asDN15、DN50);


Can also be used in the case of wall thickness involving wall thicknessDeCome to mark;Take the galvanized welded steel pipe as an example,useDN、DeThe two labels are as follows:DN20 De25 x 2.5mmDN25 De32 x 3mmDN32 De40 x 4mmDN40 De50 x 4mmetc……;

2、Seamless steel pipe、Welded steel pipe(Stamping or helical seam)、Copper tube、Stainless steel pipe,The pipe is suitable x Wall thickness Express(Such asDe108 x 4、De159 x 4.5Wait);Seamless steel pipe or colored metal pipeline,Be labeled“Outer diameter x Wall thickness”。E.gφ108 x 4,φMay omit;


3、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);

(brass tube 1 inch)

4、Plastic pipe,The pipe trail should be expressed according to the product standard method.;Usually plastic tubes are expressed in the outer diameter,We are briefly called during the actual construction process.20、25、32Waiting for pipesDe,Instead ofDN,Here is a specification。Don't figure it out, it is easy to buy、Loss during construction;


5、When design is used in diameterDNTime,Negotiable diameterDNCompared with the corresponding product specifications。



(brass tube 1 inch)three、De、DN、d、φEach representation

(brass tube 1 inch)

1、De--PPR、PETube、Polypropylene tube outer diameter;

2、DN--Polyvinyl chloride(PVC)Tube、Cast iron pipe、Steel-plastic composite tube、Galvanized steel pipe nominal diameter;

(brass tube 1 inch)3、φ--Seamless steel pipe or colored metal pipes should be marked“Outer diameter x Wall thickness”,Such as:φ108X4。

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

(brass tube 1 inch)

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。


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,

(brass tube 1 inch)

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.。)
