電加熱管使用壽命縮短原因

今日出廠產品展示及部分報價

加熱管為何“短命”
Heating pipe why “short-lived”
外殼:
Shell:
有縫與無縫
Welded and seamless
1、有縫管一般能夠承受的最大使用壓力在20公斤以內,這是最安全的使用范圍。;
1, tube maximum working pressure can usually afford within 20 kg, which is used the most secure. ;
2、無縫管可以承受超高壓,當然其壁厚也會隨之增加,這需要根據壓力要求來進行設計。
2, the seamless tube can withstand high pressure, the wall thickness will increase, which needs to design according to pressure.
3、當前有一些有縫鋼管無縫化處理的管,它是對焊縫進行了退火處理,消除了焊縫的殘余應力,使焊縫與母材相當,其承壓范圍基本與無縫管相當。也可考慮使用。
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、當然市場上也有一些采用有縫鋼管整體加熱以后再拉拔或帶芯頭軋制的無縫鋼管,主要以小規格為主,這類管僅在外形方面屬于無縫管,其實質并不是很好,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!
如果使用壓力高于20公斤仍使用有縫管或者采用第四種仿無縫管,將可能出現加熱介質滲入管內引起短路而產生爆管。
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
外殼的壁厚也是使用壽命的重要影響因素,如果為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.
材質
Texture of material
管材的成分我們普通消費者當然很難分辨,這就讓那些不誠實的商家有利可圖。
Pipe component of our ordinary consumers certainly difficult to distinguish, this let those dishonest businessmen have good prospects of gain.
1)不銹鋼202和不銹鋼304基本性能差不多只是鎳含量少了,比不銹鋼304容易生銹。
1) of 202 stainless steel and stainless steel 304 basic properties of nickel content in just less than 304 stainless steel, easy to rust.
為維護顧客利益我們介紹兩種識別方法。
To safeguard the interests of customers we introduce two kinds of recognition methods.
識別方法:
Identification method:
1、摩擦火花鑒別法:分別用304材質和202材質,放在高速旋轉的砂輪機看產生的火花,由于摩擦高溫作用,各種元素微粒氧化時產生的火花數量、形狀分叉等不同來鑒別材料化學成分和大致含量。
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、不銹鋼藥水鑒別方法:可以到不銹鋼配件店(如江頭繁盛、欣永盛)購買,單價15元一瓶。將不銹鋼識別藥水分別放在不同的材質上,二到三分鐘可以分辯出來,會顯示不同的顏色,再參照說明書對比。
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.
加熱介質
Heating medium
水垢是影響加熱管壽命相對較大的因素。電熱管在用于加熱的水可能多是用地下水,或者自來水,雜質較多,易結水垢,水垢太多太厚,會導致電熱管內部溫度無法擴散,從而導致電熱管爆管。
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.
處理方法:
Processing method:
1、目前最為有效的是加熱管進行發綠處理。
1, at present is the most effective treatment for green heating pipe.
2、采用加長型鋼芯擠壓式鎂棒,將它置于電熱管對面,可有效延長鎂棒使用壽命,確保內膽保護最大化,也不易使電熱管結垢。
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、采用加大管徑的石英玻璃電熱管。北方水質較硬,水易結垢,由于石英玻璃電熱管基材為高純度二氧化硅,二氧化硅物理化學性質不活潑,在加熱狀態下,不易吸附雜質,另外石英玻璃電熱管在加熱過程中發射遠紅外線,可起到一定的軟化水質的作用,因此這種電熱管不易結水垢。
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.
電阻絲
The resistance wire
材料的選用
The selection of materials
由于鎳鉻鐵溫度高使用壽命短,鎳鉻鋁溫度低使用壽命長所以一般為生產廠家選擇鎳鉻鐵但對顧客說使用的是鎳鉻鋁。
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.
