钢管理论重量表大全 常用钢管规格型号一览表

作为主要钢材，钢管在我们日常生活中应用广泛。石油、天然气的运输，制造建筑结构网架，制造公路桥梁等领域，可以说钢管不仅减轻了支架重量，节省了建材，还使得施工也变得越来越简易。想必在钢材买卖和建筑施工中了解钢管的重量是必要的。那么，钢管理论重量是如何计算的呢?一起来看各种钢管理论重量表大全。无缝钢管理论重量表：镀锌钢管理论重量表：镀锌钢管重量计算公式：[(外径-壁厚)*壁厚]*0.02466=kg/米(每米的重量)不锈钢管理论重量表：焊接钢管理论重量表：螺旋钢管理论重量表：矩形方钢管理论重量表：方矩形钢管理论重量计算公式：正方形和长方形(矩形)截面碳钢钢管：每米重量单位:kg/m(千克/米)&lb/ft(磅/英尺)常用方矩管计算公式为：(长+宽)×2÷3.14-厚度×厚度×0.02466=kg/m公式二：kg/m=(Oc-4Wt)*Wt*0.00785其中：Oc是钢管外周长，Wt是钢管壁厚;正方形Oc=4*a;长方形Oc=2a+2ba,b是边长通俗的解释为：4x壁厚x(边长-壁厚)x7.85其中，方管边长和壁厚都以毫米为单位，直接把数值代入上述公式，得出即为每米方管的重量，以克为单位。钢管鉴别1.伪劣钢管易出现折叠。折叠是钢管表面形成的各种折线，这种缺陷往往贯穿整个产品的纵向。产生折叠的原因是由于伪劣厂家追求高效率，压下量偏大，产生耳子，下一道轧制时就产生折叠，折叠的产品折弯后就会开裂，钢材的强度大下降。2.伪劣钢管外表经常有麻面现象。麻面是由于轧槽磨损严重引起钢材表面不规则的凹凸不平的缺陷。由于伪劣钢管厂家要追求利润，经常出现轧槽轧制最超标。3.伪劣钢管表面易产生结疤。原因有两点：(1).伪劣钢管材质不均匀，杂质多。(2)。伪劣材厂家导卫设备简陋，容易粘钢，这些杂质咬人轧辊后易产生结疤。4.伪劣材表面易产生裂纹，原因是它的坯料是土坯，土坯气孔多，土坯在冷却的过程中由于受到热应力的作用，产生裂痕，经过轧制后就有裂纹。5.伪劣钢管容易刮伤，原因是伪劣钢管厂家设备简陋，易产生毛刺，刮伤钢材表面。深度刮伤降低钢材的强度。6.伪劣钢管无金属光泽，呈淡红色或类似生铁的颜色，原因有两点二、它的坯料是土坯。2、伪劣材轧制的温度不标准，他们的钢温是通过目测的，这样无法按规定的奥氏体区域进行轧制，钢材的性能自然就无法达标。7.伪劣钢管的横筋细而低，经常出现充不满的现象，原因是厂家为达到大的负公差，成品前几道的压下量偏大，铁型偏小，孔型充不满。8.伪劣钢管的横截面呈椭圆形，原因是厂家为了节约材料，成品辊前二道的压下量偏大，这种螺纹钢的强度大大地下降，而且也不符合螺纹钢外形尺寸的标准。9.优质钢材的成分均匀，冷剪机的吨位高，切头端面平滑而整齐，而伪劣材由于材质差，切头端面常常会有掉肉的现象，即凹凸不平，并且无金属光泽。而且由于伪劣材厂家产品切头少，头尾会出现大耳子。以上就是有关钢管理论重量表的相关内容，希望能对大家有所帮助！土巴兔装修网，材料品质化、工艺规范化、管理统一化，建有后期保障服务，让您放心、省心。

无缝钢管理论重量表大全及计算方法

对于钢管相信大家都知道，在房子建造或装修等中我们都可以见到，除此之外无缝钢管还有很多其他的用途，今天小编和大家分享的是无缝钢管理论重量表大全及计算方法：什么是无缝钢管?无缝钢管具有中空截面，大量用作输送流体的管道，如输送石油、天然气、煤气、水及某些固体物料的管道等。钢管与圆钢等实心钢材相比，在抗弯抗扭强度相同时，重量较轻，是一种经济截面钢材，广泛用于制造结构件和机械零件，如石油钻杆、汽车传动轴、自行车架以及建筑施工中用的钢脚手架等用钢管制造环形零件，可提高材料利用率，简化制造工序，节约材料和加工工时，如滚动轴承套圈、千斤顶套等，已广泛用钢管来制造。无缝钢管理论重量表大全:外径mm壁厚mm0.500.600.801.01.21.41.51.61.82.02.22.52.83.03.2每米重量kg60.070.080.100.120.140.160.170.170.190.2070.080.100.120.150.170.190.200.210.230.250.260.2880.090.110.140.170.200.230.240.250.280.300.320.3490.110.120.160.200.230.260.280.290.320.350.370.400.43100.120.140.180.220.260.300.310.330.360.400.420.460.500.520.54110.130.150.200.250.290.330.350.370.410.440.480.520.570.590.62120.140.170.220.270.320.370.390.410.450.490.530.590.640.670.69130.150.180.240.300.350.400.430.450.500.540.590.650.700.740.77140.170.200.260.320.380.440.460.490.540.590.640.710.770.810.85150.180.210.280.350.440.470.500.530.590.640.690.770.840.890.93160.190.230.300.370.440.500.540.570.630.690.750.830.910.961.01170.200.240.320.400.470.540.570.610.680.740.800.890.981.041.09180.220.260.340.420.500.570.610.650.720.790.860.961.051.111.17190.230.270.360.440.530.610.650.690.760.840.911.021.121.181.25200.240.290.380.470.560.640.680.730.810.890.971.081.191.261.33210.250.300.400.490.590.680.720.770.850.941.021.141.261.331.41220.270.320.420.520.620.710.760.850.941.041.131.271.391.481.56230.280.330.440.540.650.750.800.850.941.041.131.271.391.481.56240.290.350.460.570.680.790.830.890.991.091.181.331.461.551.64250.300.360.480.590.700.820.870.921.031.131.241.391.531.631.72270.330.390.520.640.760.880.941.001.131.231.341.511.671.781.88280.340.410.540.670.790.920.981.041.161.281.401.571.741.851.96290.350.420.560.690.820.951.021.081.211.331.451.631.811.922.04300.360.440.580.720.850.991.051.121.251.381.511.701.882.002.12320.390.470.620.770.911.061.131.201.341.481.621.822.022.152.27340.410.500.660.810.971.131.201.281.431.581.721.942.152.292.43350.430.510.640.841.001.161.241.321.471.631.782.002.222.372.51360.440.520.700.861.031.201.281.361.521.681.832.072.292.442.59380.460.550.730.911.091.261.351.441.611.781.942.192.432.592.75400.490.580.770.961.151.331.421.521.691.872.052.312.572.742.90421.011.211.401.501.601.791.972.162.442.712.893.0644.51.071.281.491.591.691.902.102.292.592.883.073.26451.091.301.511.611.711.922.122.322.622.913.113.30481.161.391.611.721.832.052.272.482.813.123.333.54501.211.141.681.791.912.142.372.592.933.263.483.70511.231.471.711.831.952.182.422.562.993.333.553.77531.281.531.781.912.032.272.522.763.113.473.703.93541.311.561.821.942.072.322.562.813.183.543.774.01561.361.621.892.022.152.412.662.923.303.673.924.17571.381.651.922.052.192.452.712.973.363.744.004.25601.461.742.022.162.312.582.863.143.553.954.224.48631.531.832.132.272.422.723.013.303.734.164.444.72651.581.892.202.352.502.813.113.413.854.294.594.88681.651.982.302.462.622.933.263.574.044.494.815.12701.702.042.372.532.703.033.353.684.164.654.965.28731.782.122.472.642.823.163.503.844.354.845.185.52无缝钢管理论重量计算方法:计算常用型材理论重量计算公式：m=F×L×ρm—质量Kg;F—断面积m2;L—长度m;ρ—密度*Kg/m3其中：F断面积计算方法：1、方钢F=a22、钢管F=3.1416×$(D-$)D—直径$—厚度3、钢板、扁钢F=a×$a—宽度密度：钢材：7.85*103kg/m3铝：2.5～2.95*103铜：8.45～8.9*103铸铁：6.6～7*103尼龙：1.04～1.15*103无缝钢管理论重量表大全及计算方法的相关内容就和大家分享到这里了，更多信息请大家继续关注土巴兔学装修。阅读本文的人还喜欢：螺纹规格表螺纹规格大全h型钢理论重量表大全h型钢多少钱1吨钢筋理论重量表钢筋重量是怎么计算的
