Theoretical weight of sanitary pipe fittings

1. Calculation method of theoretical weight of metal materials (unit: kg)

Angle steel: weight per meter = 0.00785*(edge ​​width + edge width - edge thickness)*edge thickness Round steel: weight per meter = 0.00617*diameter*diameter (same for threaded steel and round steel) Flat steel: weight per meter = 0.00785*thickness*edge width

Pipe: weight per meter = 0.02466*wall thickness*(outer diameter-wall thickness) Stainless steel pipe: (outer diameter-wall thickness)×wall thickness×0.02491=kg/m Plate: weight per meter = 7.85*thickness

Brass pipe: weight per meter = 0.02670*wall thickness*(outer diameter-wall thickness) Copper pipe: weight per meter = 0.02796*wall thickness*(outer diameter-wall thickness) Aluminum patterned plate: weight per square meter = 2.96 * thickness

Specific gravity of non-ferrous metals: 8.9 for copper plate, 8.5 for brass plate, 7.2 for zinc plate, 11.37 for lead plate. The calculation formula for non-ferrous metal plates is: weight per square meter = specific gravity * thickness. 2. Elbow weight calculation formula

Ring volume = 2X3.14X3.14(r^2)R r--Ring radius R--Ring turning radius

Hollow tube ring volume = 2X3.14X3.14((r^2)-(r’^2))R r’--Ring inner radius

The volume of 90, 60, and 45 degree elbows (elbows) is 1/4, 1/6, and 1/8 of the corresponding hollow tube ring volume respectively. The density of steel is calculated as 7.85 kg/cubic decimeter in engineering, and density*volume=weight (mass). 1. 180° elbow is calculated as 2 times of the table, and 45° is calculated as 1/2; 2. R1.0DN elbow weight is calculated as 2/3 of the table;

3. The weight of the wall thickness is not listed in the table, and the average value of two weights close to it can be taken; 4. 90° elbow calculation formula; 0.0387*S(D-S)R/1000 Where S=wall thickness mm D=outer diameter mm R=bending radius mm

2. The following is the calculation formula of Sanitary Elbow

1. Outer diameter-wall thickness X wall thickness X0.0387X bending radius ÷ 1000, = theoretical weight of 90° elbow Example: 426*10 90°R=1.5D

(426-10)*10*0.387*R600÷1000=96.59Kg 180° elbow is calculated as 2 times of the table, and 45° is calculated as 1/2; 2..(outer diameter-wall thickness)Xwall thicknessX0.02466XR multipleX1.57Xnominal diameter=theoretical weight of 90° elbow

Example: Example: 426*10 90°R=1.5D

(426-10)*10*0.02466*1.5D*1.57*400=96.6Kg 180° elbow is calculated as 2 times of the table, 45° is calculated as 1/2.
