焊管尺寸规格表.doc

焊管尺寸规格表焊接钢管采用的坯料是钢板或带钢，因其焊接工艺不同而分为炉焊管、电焊（电阻焊）管和自动电弧焊管。因其焊接形式的不同分为直缝焊管和螺旋焊管两种。因其端部形状又分为圆形焊管和异型（方、扁等）焊管。焊管因其材质和用途不同而分为如下若干品种：GB/T3091-2001（低压流体输送用镀锌焊接钢管）。GB/T14291-2006（矿用流体输送焊接钢管）。GB/T14980-1994（低压流体输送用大直径电焊钢管）。GB/T12770-2002（机械结构用不锈钢焊接钢管）。GB/T12771-1991（流体输送用不锈钢焊接钢管）。装饰用焊接不锈钢管（GB/T 18705-2002），建筑装饰用不锈钢焊接管材（JG/T 3030-1995），低压流体输送用大直径电焊钢管（GB/T 3091-2001），换热器用焊接钢管（YB4103-2000）。 外径 mm焊管尺寸规格表 壁 厚mmO50.6O.81O1.21.41.51.61.82O2.22,52.83.03.23.5钢管的理论质量(kgm)38 0.9121.0891.2641.3501.4361.6071.7761.9422.1892.4302.5892.7462.97840 O9621.1481.3331.4241.5151.6961.8742.0512.3122.5692.7372.9043.15045 1.091.301.5l1.611.711.922.122.322.622.913.113.303.5846 1.331.541.651.751.962.172.382.682.983.183.383.66848 1.381.6l1.721.832.052.272.482.813.123.333.543.8450 1.441.681.791.912.142.372,592.933.263.483.694Ol5l 1.471.711.831.952.182.422.652.993.333.553.774.1053 1.531.781.902.032.272.522.763.113.473.703.934.2754 1.561.821.942.072.322.562.813.173.543.774.014.3660 1.742.022.162.302.582.863.143.543.954.224.484.8863.5 1.842.142.292.442.743.033.333.764.194.484.765.1865 2.352.502.813.113.413.854.294.594.885.3170 2.372.703.033.353.684.164.644.965.275.7476 2.762.943.293.654.004.535.055.405.746.2680 2.903.093.473.854.224.785.335.706.066.6083 3OI3.2l3.603.994.384.965.545.926.306.8689 3.243.453.874.294.715.335.956.366.777.3895 3.463.694.144.595.035.706.376.8l17.247.90101.6 3.703.954.434.915.396.116.827.297.768.47102 3.723.964.454.935.416.136.857.327.808.50焊管尺寸规格表 外径 mm壁 厚mm O50.60.81.01.21.41.51.61.82O2.22.52.83.03.23.5钢管的理论质量(kgm) 5O0550.065O083O099 80.092O109O142O173O201 100.117O1390.1810.2220.260 120.142O169O221O271O320O366O3880.410 13 O1830.2410.296O3430.400O4250.450 14 0.198O260O321O379O435O462O489 15 O1230.280O3450.408O470O499O529 16 O228O300O3700.4380.504O536O568 17 0.243O320O395O4680.359O573O608 18 0.2570.339O419O497O5730.6100.647 19 O272O3590,4440.5270.608O647O687 20 0.2870.379O469O556O642O684O7260.8080.888 21 0.3990.4930.5860.677O721O7650.8520.937 22 O418O518O616O7UO758O805O8970.9861.074 25 O477O592O7040.815O869O9231.0301.1341.2371.387 28 O537O666O7930.918O9801.04121.1631.2821.4001.5721.740 30 0.576O7150.8520.9871.0541.1211.2521.3811.5081.6951.8781.997 32 O7640.9111.0651.1281.1991.3411.4801.6171.18192.0162.145 34 O814O9711.1251.2021.2781
