通常客户在采购防腐方管的时候收到的报价有高有低，甚至不同厂家的防腐方管价格还会相差很多，这是为什么呢？选购防腐方管大家会发现，在现代市场环境中，防腐方管的种类非常多，不同类型厂家销售的防腐方管价格定位不统一，主要原因就是很多因素会导致价格定位出现正常的浮动。下面方管厂家就来为大家全面解析，导致价格定位不统一的原因。首先要说的是没有一个厂家会傻到报高于市场的价格的来把客户推走，造成防腐方管价格相差的原因主要是成本的核算，现在我们来给大家说一下成本方面的差别。防腐方管厂家规模大的厂家要比规模小的厂家报价高，因为规模大的防腐方管厂家生产工艺比较严格，技术成熟，售后有保障，而一些小型的保温加工厂家就没有这些了；另外最主要的还是在原料的差别上。

Usually, when purchasing anticorrosive square pipes, the quotations received by customers are high and low, and even the prices of anticorrosive square tubes from different manufacturers will vary a lot. Why? You will find that in the modern market environment, there are many kinds of anticorrosive square tubes, and the price positioning of anticorrosive square tubes sold by different manufacturers is not uniform. The main reason is that many factors will cause the price positioning to fluctuate normally. The following square tube manufacturers will come to a comprehensive analysis for you, resulting in the price positioning is not unified. The first thing to say is that no manufacturer will be foolish enough to offer higher than the market price to push customers away. The main reason for the price difference of anticorrosion square tube is cost accounting. Now let's talk about the difference in cost. Large scale manufacturers offer higher prices than small-scale manufacturers, because large-scale manufacturers have strict production process, mature technology and guaranteed after-sales service, while some small-scale heat preservation processing manufacturers do not have these; in addition, the most important thing is the difference of raw materials.

首先，我们来说防腐方管的外护套聚乙烯管，防腐方管的保护层聚乙烯外护套管是由高密度聚乙烯生产而成，在生产聚乙烯外护套管的时候都是由原料和二次料（回收料）按照一定的配比生产而成，比例的不同造就了价格的高低，原包料掺的多外护管质量就好，价格也就更贵，二次料掺的多质量就差一点，价格也就低一点；中间聚氨酯发泡保温层这方面差的不是太多，不过好一点的聚氨酯发泡剂还是要贵一点的，差一点的聚氨酯发泡剂生产出来的保温管在长时间存放下会出现热胀冷缩的现象，导致防腐方管还未使用保温层和外护套已经分离；最后说的就是最里面的工作钢管了，防腐方管选用的工作钢管当然是方管了，方管分为部标和国标，国标的方管要比部标方管每吨高400元左右，客户在采购的时候要问清楚防腐方管厂家给报的是国标还是部标。

First of all, let's talk about the outer sheath polyethylene pipe of the anticorrosive square pipe. The protective layer of the anti-corrosion square pipe is made of high-density polyethylene. When producing the polyethylene outer protective sleeve, the raw material and secondary material (recycled material) are produced according to a certain ratio. The different proportion leads to the price. If the raw materials are mixed with more, the quality of the outer protective tube is better The grid is more expensive. The quality of secondary materials is poor, and the price is lower. The polyurethane foam insulation layer in the middle is not too poor, but the better polyurethane foaming agent is still more expensive. The insulation pipe produced by the worse polyurethane foaming agent will expand and contract when stored for a long time, resulting in that the anticorrosive square pipe has not yet used the thermal insulation layer It has been separated from the outer sheath. The last thing to say is the inner working steel pipe. Of course, the working steel pipe used for anticorrosion square pipe is square pipe. The square pipe is divided into ministry standard and national standard. The square pipe of national standard is about 400 yuan higher than that of the ministry standard square pipe. Customers should ask whether the anti-corrosion square pipe manufacturer reports the national standard or the ministry standard when purchasing.

以上就是防腐方管各个厂家报价不一的主要原因了，俗话说一分钱一分货，采购防腐方管的时候建议客户不要一味的追求价格便宜，也不要去一味的追求质量高，并不是价格高就是最好的，买东西还是讲求合适，毕竟管道工程是一项利民的重大工程，按实际情况选购，只有选购了合适的防腐方管才能建造最好的保温管道。

防腐方管价格定位不一的具体原因

首先，销售防腐方管价格定位不统一，主要原因就是防腐方管的类型不同，在使用功能特点方面会有很大差异，难免就会导致成本价格出现浮动，所以销售价格定位就会出现变化。只要你选择专业值得信赖的厂家来定制防腐方管符合实际应用需求，就能保证其功能效果更好价格定位合理。

其次，之所以现在防腐方管的价格定位会有很大差异原因就是各大厂家生产加工成本不同，投入的设计研发水平不一样，难免在价格定位方面就会有变化。建议大家不要只是单纯的关注价格高低，而是要确保在价格竞争方面是否合理，在技术水平和生产质量方面达到相应的标准，才能计算价格定位是否符合标准。

之所以防腐方管价格定位不统一，主要就是因为以上这些原因所导致的，建议大家购买防腐方管要保持理性的心态，不管在任何环境下安装防腐方管，都要选择符合安装环境需求的路灯类型。确保防腐方管的优势得到发挥，还能在实际应用中具有更好的优势特点。
