方管市场价格或继续窄幅盘整涨后成交尚可方管唐山方管市场价格高位低靠。受昨日期螺尾盘走高以及夜盘高位震荡影响，今早盘市场信心略有提振，唐山主流钢厂钢坯拉涨10元，涨后成交尚可。不过随着期螺盘面走势下行，中板方面趋弱调整，商家出货较为乏力，钢坯拉涨及低库存的支撑力度较小，整体市场交投氛围显谨慎，操作多显观望。短期来看，期货市场处于洗…

作为一个生产方管的厂家要对方管的各个工艺流程、钢管材质性能有足够的掌握，在客户订购焊管的时候方管和矩形管是客户的选择对象。我们多次提到方管和矩形管的优劣，方管在生产过程中只有管端的尺寸是最严格的的，毕竟方管不同于矩形管，所以在生产方管的时候要注意把口径和管端做到最好，以便于在安装焊接过程中能够方便快捷的施工。对于生产大口径钢管壁厚较薄的钢管的时候要注意加固或者对钢管做支架，以防止方管在运输过程中出现椭圆或口径变形。对于方管来说口径的准确尺寸是最重要的，其次要注意的是方管焊口不要咬边，要把卷制好的钢管的两个焊边对齐对平，焊接出来的钢管才能漂亮、规范。其次要注意的是方管的直度，方管的直度不但影响方管整体的外观最主要的是影响后期施工焊接。

As a manufacturer of square pipe, we should have a good command of each process and material properties of square pipe. When customers order welded pipe, square pipe and rectangular pipe are the customers'choices. We have repeatedly mentioned the advantages and disadvantages of square pipe and rectangular pipe, square pipe in the production process only the pipe end size is the most stringent, after all, square pipe is different from rectangular pipe, so in the production of square pipe, we should pay attention to the caliber and pipe end to do the best, so as to facilitate the installation and welding process can be convenient and fast construction. For the production of large diameter steel pipe with thinner wall thickness, attention should be paid to strengthening or bracketing steel pipe to prevent ellipse or caliber deformation of square pipe during transportation. For square pipe, the exact size of the caliber is the most important. Next, we should pay attention to the square pipe weld without undercutting. We should align the two weld edges of the rolled steel pipe, so that the welded steel pipe can be beautiful and standard. Secondly, attention should be paid to the straightness of square pipes. The straightness of square pipes not only affects the overall appearance of square pipes, but also affects the later construction welding. 

天津镀锌方管价格在短期限内仍将弱势下行成…方管本周天津镀锌方管市场价格震荡走低，整体成交量又见萎缩。周内，在上游方坯、带钢价格小幅震荡的带领下，本地主流焊镀 管厂价格继续维持窄幅调整。由于对后市预期并不看好，管厂根据自身情况采取了不同程度的减产检修的方式来规避风险，在产量下降的情况下，虽然成交不佳，厂 内成品库存并没增量，反而呈下降趋势。据了解，受… 方管市场旺季不旺原因在于厂家经营模式陈旧…方管近年来，方管行业的发展已经趋近成熟的状态，发展到了一定程度自然不能用传统营销模式。因此方管行看似不像以往那样生意红火，其实是到了该转变经营模式的时候。业内人士对于方管行业平淡并不意外，方管促销活动玩出新花样才能带来新一轮“旺季”。据发现，近日广州方管市场节后仍在促销。然而，低价促销并未改变家居市场的冷…
