电加热管使用寿命缩短原因

今日出厂产品展示及部分报价

加热管为何“短命”
Heating pipe why “short-lived”
外壳:
Shell:
有缝与无缝
Welded and seamless
1、有缝管一般能够承受的最大使用压力在20公斤以内,这是最安全的使用范围。;
1, tube maximum working pressure can usually afford within 20 kg, which is used the most secure. ;
2、无缝管可以承受超高压,当然其壁厚也会随之增加,这需要根据压力要求来进行设计。
2, the seamless tube can withstand high pressure, the wall thickness will increase, which needs to design according to pressure.
3、当前有一些有缝钢管无缝化处理的管,它是对焊缝进行了退火处理,消除了焊缝的残余应力,使焊缝与母材相当,其承压范围基本与无缝管相当。也可考虑使用。
3, there are some seamed steel pipe seamless processing tube, it is to weld the annealing treatment, to eliminate the residual stress of the weld, the weld and base material, the pressure range of seamless tube and a basic. Also can consider to use.
4、当然市场上也有一些采用有缝钢管整体加热以后再拉拔或带芯头轧制的无缝钢管,主要以小规格为主,这类管仅在外形方面属于无缝管,其实质并不是很好,要注意哦!
4, there are also some of the tube with integral heating after drawing or mandrel rolling seamless steel pipe, mainly to small size, this kind of tube only in appearance of seamless pipe, in fact is not very good, pay attention to oh!
如果使用压力高于20公斤仍使用有缝管或者采用第四种仿无缝管,将可能出现加热介质渗入管内引起短路而产生爆管。
If you use a pressure higher than 20 kg is seamed tube or by using fourth kinds of imitation seamless pipe, will likely heating medium pipe cause a short circuit caused tube bursting.
壁厚
Wall thickness
外壳的壁厚也是使用寿命的重要影响因素,如果为了省材料做的太薄可能引起爆管。
The important factors influencing the shell wall thickness and service life in order to save material, if too thin may cause a burst pipe.
材质
Texture of material
管材的成分我们普通消费者当然很难分辨,这就让那些不诚实的商家有利可图。
Pipe component of our ordinary consumers certainly difficult to distinguish, this let those dishonest businessmen have good prospects of gain.
1)不锈钢202和不锈钢304基本性能差不多只是镍含量少了,比不锈钢304容易生锈。
1) of 202 stainless steel and stainless steel 304 basic properties of nickel content in just less than 304 stainless steel, easy to rust.
为维护顾客利益我们介绍两种识别方法。
To safeguard the interests of customers we introduce two kinds of recognition methods.
识别方法:
Identification method:
1、摩擦火花鉴别法:分别用304材质和202材质,放在高速旋转的砂轮机看产生的火花,由于摩擦高温作用,各种元素微粒氧化时产生的火花数量、形状分叉等不同来鉴别材料化学成分和大致含量。
1, the friction spark identification method: using 304 material and the 202 material, on the wheel rotating see sparks, due to friction at high temperature, various elements oxidation when the spark quantity, shape bifurcation to identification of chemical components of different materials and general content.
2、不锈钢药水鉴别方法:可以到不锈钢配件店(如江头繁盛、欣永盛)购买,单价15元一瓶。将不锈钢识别药水分别放在不同的材质上,二到三分钟可以分辩出来,会显示不同的颜色,再参照说明书对比。
2, stainless steel medicine identification method: to stainless steel accessories shop (such as the river head bloom, Xin Yongsheng) to buy, the price of 15 yuan a bottle. The stainless steel recognition drops were placed on different materials, two to three minutes can tell, will show different colors, and then refer to manual comparison.
加热介质
Heating medium
水垢是影响加热管寿命相对较大的因素。电热管在用于加热的水可能多是用地下水,或者自来水,杂质较多,易结水垢,水垢太多太厚,会导致电热管内部温度无法扩散,从而导致电热管爆管。
Factors influencing service life of heating pipe scale is relatively large. Electric heating pipe for heating water in May is the use of groundwater, or tap water, impurities, easy scaling, scale is too thick, you will not be able to spread the internal temperature of electric heating tube, which leads to the electrothermal tube.
处理方法:
Processing method:
1、目前最为有效的是加热管进行发绿处理。
1, at present is the most effective treatment for green heating pipe.
2、采用加长型钢芯挤压式镁棒,将它置于电热管对面,可有效延长镁棒使用寿命,确保内胆保护最大化,也不易使电热管结垢。
2, use longer steel core extruded magnesium rod, place it in the electric heating tube opposite, can effectively prolong the service life of the magnesium rod, to ensure maximum protection, is not easy to make the electric heating tube scaling.
3、采用加大管径的石英玻璃电热管。北方水质较硬,水易结垢,由于石英玻璃电热管基材为高纯度二氧化硅,二氧化硅物理化学性质不活泼,在加热状态下,不易吸附杂质,另外石英玻璃电热管在加热过程中发射远红外线,可起到一定的软化水质的作用,因此这种电热管不易结水垢。
3, to increase the use of quartz glass heating pipe diameter pipe. The quality is hard, the water scaling easy, because the quartz glass heating tube material is high purity silicon dioxide, the chemical and physical properties of silicon dioxide inert, in the heating mode, and is not easy to absorb impurities, and quartz glass heating tube emits far infrared rays in the heating process, can play a water softening effect, so the electric heating the tube is not easy to scale.

材料的选用
The selection of materials
由于镍铬铁温度高使用寿命短,镍铬铝温度低使用寿命长所以一般为生产厂家选择镍铬铁但对顾客说使用的是镍铬铝。
Because of high temperature and short service life of nickel chromium, nickel chromium iron but choose to customers are using Ni Cr al Ni Cr low temperature long life so general is the manufacturer.
