目前我国翅片管生产材料主要分以下几类

目前我国翅片管生产材料主要分以下几类：铸铁翅片管、钢制翅片管、铝制翅片管、铜铝复合翅片管和铜制翅片管。据业内专家分析预测，铜制翅片管作为新型翅片管，具备了成为主角的强劲实力。翅片管厂方面，前一日(9日)宝钢发布6月份板材价格政策后，河北翅片管集团10日也公布了建筑翅片管中旬指导价格政策，基本与上旬持平。河钢的维稳操作既显示对后期走势并不看好，也暗示当前价格跌幅空间已不会太大，而宝钢的年内首次降价从时间点上也要滞后后国内其他一线翅片管厂两个月左右，因此，其对板材市场价格的影响力度恐不会太大。At present, China's finned tube production materials are mainly divided into the following categories: cast iron finned tube, steel finned tube, aluminum finned tube, copper-aluminum composite finned tube and copper finned tube. According to the analysis and prediction of experts in the industry, copper finned tube as a new type of finned tube, has become a protagonist with strong strength. Finned tube factory, the previous day (9) Baosteel announced the June plate price policy, Hebei Finned Tube Group 10 also announced the construction finned tube mid-ten guidance price policy, basically the same as the previous ten days. The stabilization operation of Hegang not only shows that it is not optimistic about the later trend, but also implies that the space for the current price decline is not too large. The first price reduction of Baosteel in the year will lag behind the other domestic first-line finned tube mills for about two months. Therefore, its influence on the plate market price will not be too great.一是铜制翅片管可无条件使用于目前的供暇环境我国实行集中供暖，在开放式系统下，要求翅片管具有很好的防腐能力。先前的铸铁翅片管和钢制翅片管怕氧化腐蚀，做防腐处理增加了其系统成本和费用。铝制翅片管最怕碱性水腐蚀和电化学腐蚀，无法从根本上解决开放式系统下的腐蚀问题。只有铜制翅片管其独特的主动防腐性能使系统更安全，使用寿命更高，可达到无条件使用。Firstly, copper finned tube can be unconditionally used in the current leisure environment of central heating in China. Under the open system, finned tube is required to have good corrosion resistance. Previous cast-iron finned tubes and steel finned tubes were resistant to oxidation corrosion, and anticorrosion treatment increased their system costs and costs. Aluminum finned tube is most afraid of alkaline water corrosion and electrochemical corrosion, which can not fundamentally solve the corrosion problem in open system. Only the copper finned tube with its unique active anti-corrosion performance makes the system safer, longer service life, and can be used unconditionally.宏观方面，央行10日公布的数据显示，4月社会融资规模1.75万亿元，比上年同期多7833亿元，其中，人民币贷款增加7929亿元，同比多增1111亿元。4月新增贷款低开上月的1.06万亿，显示我国经济复苏势头整体疲软。无论是一季度的国内生产总值表现还是4月份已公布的经济数据，均显示我国经济复苏大幅低于市场预期，整体压制用钢需求。Macroscopically, data released by the central bank on the 10th showed that the scale of social financing in April was 1.75 trillion yuan, 783.3 billion yuan more than the same period last year. Among them, Renminbi loans increased by 792.9 billion yuan, 111.1 billion yuan more than the same period last year. New loans in April opened lower than 1 trillion and 60 billion last month, indicating that China's economic recovery is weakening. Both the GDP performance in the first quarter and the economic data published in April show that China's economic recovery is substantially lower than market expectations, and the overall suppression of steel demand.本站网址：http://www.jlrnsb.com辛苦整理.转载请注明http://www.wxsxsjx.com 方管
