焊管尺寸规格表.pdf

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/T18705-2002），建筑装饰用不锈钢焊接管材（JG/T3030-1995），低压流体输送用大直径电焊钢管（GB/T3091-2001），换热器用焊接钢管（YB4103-2000）。外焊管尺寸规格表壁厚／mm径0.O.O．51．O1.21.41.51.61.82．O2.22,52.83.03.23.568／m钢管的理论质量／(kg／m)m1.081.261.351.431.601.771.942.182.432.582.74380.9122.97894067629096O．91.141.331.421.511.691.872.052.312.562.732.90403.1506283456412974451.091.301.5l1.611.711.922.122.322.622.913.113.303.58461.331.541.651.751.962.172.382.682.983.183.383.668481.381.6l1.721.832.052.272.482.813.123.333.543.84501.441.681.791.912.142.372,592.933.263.483.694．Ol5l1.471.711.831.952.182.422.652.993.333.553.774.10531.531.781.902.032.272.522.763.113.473.703.934.27541.561.821.942.072.322.562.813.173.543.774.014.36601.742.022.162.302.582.863.143.543.954.224.484.88631.842.142.292.442.743.033.333.764.194.484.765.18.5652.352.502.813.113.413.854.294.594.885.31702.372.703.033.353.684.164.644.965.275.74762.762.943.293.654.004.535.055.405.746.26802.903.093.473.854.224.785.335.706.066.60833．OI3.2l3.603.994.384.965.545.926.306.86893.243.453.874.294.715.335.956.366.777.38953.463.694.144.595.035.706.376.8l17.27.90来源：45#无缝钢管http://www.lcsdn.com焊管尺寸规格表4101.3.703.954.434.915.396.116.827.297.768.476103.723.964.454.935.416.136.857.327.808.502焊壁厚／mm管O3.3.0.60.81.01.21.41.51.61.82．O2.22.52.83.0尺．525寸规格表外钢管的理论质量／(kg／m)径／mmOO0.0O．05．0．065835599OOO0.0O．18．1．1．29242097301O0.10.180.20.210．1171226039OOOO0.1O．2O．30.4112．1．2．3．3422188069712066OO0.240.20.4O．40.4513．1．3196002508343OOO0.1O．2O．4O．414．3．3．498606289217935来源：45#无缝钢管http://www.lcsdn.com焊管尺寸规格表OOO0.280.4O．4O．515．1．3．40089929234570OOO．30.40.5O．5O．516．2．300380436682870OO0.2O．30.3O．5O．617．3．443205973089568OOO0.20.330.610.6418．4．4．557907199773OO．30,40.50.6O．6O．619．259442708478772OOO0.20.37O．6O．70.800.8820．4．5．68798426886956
