高频直缝电阻焊钢管高频直缝电阻焊钢管（High-frequency Electrical Resistance Welded Steel Pipe, 简称ERW ）是热轧卷板经过成型机成型后，利用高频电流的集肤效应和邻近效应，使管坯边缘加热熔化，在挤压辊的作用下进行压力焊接来实现生产。世界范围内已有近20个国家在生主ERW石油专用管、输送管、结构管，目前，在 世界焊接钢管的产量中，ERW焊管产量约占焊管总产量的80左右。 与其它钢管比较，其优点如下：1、最大的特点是生产效率高，加热速度快，不存在填充金属。ERW的生产速度一般在12-40m/min，比 埋弧焊管高出几倍甚至十几倍。2、ERW焊管更容易实现质量控制，所生产的钢管尺寸精度高，外径和壁厚偏差均较小。由于不存在填 充金属，这极大地提减少了质量控制点；再加上工艺上合理的配置，在线的超声波检测随时能够 跟踪焊接的情况；而定径矫直更加使钢管得到很好的直度和外形尺寸。3、韧性优良。因采用高强度、高韧性板材，碳、硫、磷含量低，冲击韧性大大提高。4、抗挤、抗爆性能优异。与API无缝套管相比，抗挤强度高出30%40%，抗爆性能高出50% 。5、ERW 套管采用热轧卷板，管坯的晶粒度及组织的致密度高，优于无缝管。6、在价格上，ERW 钢管也颇具竞争力，且使用寿命长。 产品规格API Spec 5L 管线钢管(产品最高钢级可达X80),钢管长度:8-12.5m 外径outsidediameter (in/mm)壁厚 Wall thickness (in/mm) in0.1340.1560.1730.1880.2030.2190.2500.2790.3120.3440.3750.4060.4380.4690.5000.5000.500mm3.44.04.44.85.25.66.47.17.98.79.510.311.111.912.714.315.9inmm7177.87 5/8 193.78 5/8219.19 5/8244.510 3/4 273.111 3/4298.512304.812 3/4 323.912 3/8339.714355.616406.418457.018 5/8 473.120508.0结构管 structural tube结构钢管的产品规格Specification of Structural Tubes 外径 Outside Diameter 壁厚 Wall Thickness (mm) 4.0 4.2 4.5 4.8 5.0 5.4 5.6 6.0 6.5 7.0 8.0 9.0 10.0 11.0 12.0 12.7 mm in 钢管的理论重量 Weight (kg/m) 177.8 7 17.1 18.0 19.2 20.5 21.3 23.0 23.8 25.4 27.5 29.5 33.5 180 7.1 17.4 18.2 19.5 20.7 21.6 23.3 24.1 25.7 27.8 29.9 33.9 193.7 7.63 18.7 19.6 21.0 22.4 23.3 25.1 26.0 27.8 30.0 32.2 36.6 203 8 22.0 23.5 24.4 26.3 27.3 29.1 31.5 33.8 38.5 219.1 8.63 23.8 25.4 26.4 28.5 29.5 31.5 34.1 36.6 41.6 46.6 244.5 9.63 26.6 28.4 29.5 31.8 33.0 35.3 38.1 41.0 46.7 52.3 267 10.51 32.3 34.8 36.1 38.6 41.8 44.9 51.1 57.3 63.4 273 10.75 33.0 35.6 36.9 39.5 42.7 48.9 52.3 58.6 64.9 298.5 11.75 40.4 43.3 46.8 50.3 57.3 54.3 71.1 78.0 323.9 12.75 44.0 47.0 50.9 54.7 62.3 69.9 77.4 84.9 325 12.8 47.2 51.1 54.9 62.5 70.1 77.7 85.2 351 13.82 51.0 55.2 59.4 67.7 75.9 84.1 92.2 355.6 14 51.7 56.0 60.2 68.6 76.9 85.2 93.5 101.7 368 14.49 53.6 57.9 62.3 71.0 79.7 88.3 96.8 105.3 377 14.84 54.9 59.4 63.9 72.8 81.7 90.5 99.28 108.0 402 15.83 58.6 63.4 68.2 77.7 87.2 96.7 106.1 115.4 406.4 16 59.2 64.1 68.9 78.6 88.2 97.8 107.3 116.7 123.3 419 16.5 61.1 66.1 71.1 81.1 91.0 100.9 110.7 120.4 127.2 426 16.78 62.1 67.2 72.3 82.5 92.5 102.6 112.6 122.5 129.4 457 18 66.7 72.2 77.7 88.5 99.4 110.2 121.0 131.7 139.1 478 18.82 69.8 75.6 81.3 92.7 104.1 115.4 126.7 131.7 145.7 480 18.89 70.1 75.9 81.6 93.1 104.5 115.9 127.2 138.5 146.3 508 20 74.3 80.4 85.5 98.6 110.7 122.8 134.8 146.8 155.1 主要油管和套管产品规格类别Item规格Specification (in) 外 径outside diameter壁厚wall thickness名义重量 nominal massper meterin mm in mm lb/in kg/m 7 7 7 177.8 0.231 5.87 16.70 24.89 7 7 177.8 0.272 6.91 19.54 29.12 7 7 177.8 0.317 8.05 22.42 33.40 7 7 177.8 0.362 9.19 25.64 38.21 7 7 177.8 0.408 10.36 28.75 42.78 7 7 177.8 0.453 11.51 31.72 47.20 7 7 177.8 0.498 12.65 34.62 51.52 7 7 177.8 0.540 13.72 37.30 55.51 7-5/8 7-5/8 7-5/8 193.7 0.300 7.62 23.50 34.97 7-5/8 7-5/8 193.7 0.328 8.33 24.41 36.37 7-5/8 7-5/8 193.7 0.375 9.52 29.02 43.24 7-5/8 7-5/8 193.7 0.43 10.92 33.03 49.22 7-5/8 7-5/8 193.7 0.50 12.70 38.09 56.69 7-5/8 7-5/8 193.7 0.562 14.27 42.43 63.14 7-5/8 7-5/8 193.7 0.595 15.11 44.71 66.54 8-5/8 8-5/8 8-5/8 219.1 0.264 6.71 23.58 35.14 8-5/8 8-5/8 219.1 0.304 7.72 27.04 40.14 8-5/8 8-5/8 219.1 0.352 8.94 31.13 46.13 8-5/8 8-5/8 219.1 0.400 10.16 35.17 52.55 8-5/8 8-5/8 219.1 0.450 11.43 39.33 58.39 8-5/8 8-5/8 219.1 0.500 12.70 43.43 64.64 8-5/8 8-5/8 219.1 0.557 14.15 48.06 71.52 9-5/8 9-5/8 9-5/8 244.5 0.312 7.92 31.01 46.21 9-5/8 9-5/8 244.5 0.352 8.94 34.85 51.93 9-5/8 9-5/8 244.5 0.395 10.03 38.92 57.99 9-5/8 9-5/8 244.5 0.435 11.05 42.69 63.61 9-5/8 9-5/8 244.5 0.472 11.99 46.14 68.75 9-5/8 9-5/8 244.5 0.545 13.84 52.83 78.72 9-5/8 9-5/8 244.5 0.595 15.11 57.43 85.47 9-5/8 9-5/8 244.5 0.609 15.47 58.71 87.37 10-3/4 10-3/4 10-3/4 273.1 0.279 7.09 30.54 45.51 10-3/4 10-3/4 273.1 0.350 8.89 38.87 57.92 10-3/4 10-3/4 273.1 0.400 10.16 44.21 65.88 10-3/4 10-3/4 237.1 0.450 11.43 49.50 73.76 10-3/4 10-3/4 273.1 0.495 12.57 54.20 80.76 10-3/4 10-3/4 273.1 0.545 13.84 59.46 88.48 10-3/4 10-3/4 273.1 0.595 15.11 64.60 96.13 11-3/4 11 -3/4 11 -3/4 298.5 0.333 8.46 40.61 60.51 11 -3/4 11 -3/4 298.5 0.375 9.53 45.58 67.91 11 -3/4 11 -3/4 298.5 0.435 11.05 52.57 78.33 11-3/4 11 -3/4 298.5 0.489 12.42 58.88 87.62 11-3/4 11 -3/4 298.5 0.534 13.56 64.03 95.28 11-3/4 11 -3/4 298.5 0.582 14.78 69.49 103.41 13-3/8 13-3/8 13-3/8 339.7 0.330 8.38 49.95 68.47 13-3/8 13-3/8 339.7 0.380 9.65 52.71 78.54 13-3/8 13-3/8 339.7 0.430 10.92 59.42 88.54 13-3/8 13-3/8 339.7 0.480 12.19 66.07 98.45 13-3/8 13-3/8 339.7 0.514 13.06 70.60 105
