生产工艺上浅谈镀锌方管的区别方管简单聊聊镀锌方管的集中分类，我们先从其出产工艺上来看，这样是可以分为热镀锌方管和冷镀锌方管的。正是由于这两种镀锌方管的加不相同也就造就了它们许多不同的物理和化学性质。总的来说它们在强度、耐性和机械功能方面都有许多的差异。热镀锌方管：是在运用钢板或者是钢带弯曲成型后焊接制成的方管，并在这…

南京市场方管价格上涨，成交尚可。早盘螺纹钢期货延续夜盘强势上涨。唐山方坯累涨20元，现普碳方坯含税出厂3580元。期螺的大 涨也拉动了现货，南京市场价格多次跟涨，成交也相对顺畅。整体来看，需求对价格依然有很好的支撑，但是高价资源成交仍然较弱。不过由于期螺和钢坯的上涨， 钢厂涨价意愿强烈。综上所述，预计明日南京市场方管价格或持续上涨。

方管在生产过程中要注意的几个重点方管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… 明日长沙方管市场价格稳为主心态也逐渐谨慎…方管长沙方管市场价格均稳。近期市场变动较小，节后需求有一定跟进，低价资源出货尚可，今早钢坯有一定上调，但对市场价格影响不大，仍以稳为主，工地方面也已经步入正轨，市场自身调节后较为饱和，但价格仍缺乏支撑，午后唐山、昌黎钢坯稳，现普碳方坯含税出厂3420元，成本尚有一定支撑，期螺持绿下行，心态也逐渐谨慎，预计明日…
