陶瓷复合管说明事项

陶瓷内衬复合钢管(简称:陶瓷复合管)是国家“863”计划中研制成功并产业化具有国际先进水平的新型复合材料。陶瓷复合管从内而外分别是刚玉陶瓷(AL2O3)层、过渡层和钢管层组成,陶瓷层是由2600℃以上的熔融氧化铝在离心力的作用下均匀复合在钢管内壁后凝固形成的,致密、光滑,与钢管贴切、牢固地结合在一起。
  与传统生产工艺截然不同,采用自蔓延离心法技术生产的陶瓷钢管具有独特的组织结构。独特的组织机构又决定了它的优良的综合性能。它不但抗磨损,有高的硬度和强度,而且具有良好的抗机械冲击和热冲击的综合性能。
  由于外层是钢铁,加之内层升温也不崩裂,在施工中,对法兰、吹扫口、防爆门等能进行焊接,也可用直接焊接方法进行管道连接,这比耐磨合金铸钢管、粘贴氧化铝陶瓷、铸石管和钢塑、钢橡管在施工中不易焊接或不能焊接更胜一筹。
  陶瓷复合管综合利用了氧化铝硬度高、化学惰性、高强度和塑性好的优点,具有其它管材无法比拟的优异综合性能和良好的耐磨、耐热、耐蚀、抗机械和热冲击性能、可焊性好和安装等综合性能。特别适用于磨损、冲刷严重的物料输送场合,如燃煤发电厂、钢铁、冶金、煤炭、矿山、水泥、地质等行业的物料管道输送。据电力、煤炭、冶金等工业部门多年的使用情况,和普通无缝钢管相比,陶瓷复合管的使用寿命成十五倍地增长,可以替代铸石管、合金管、不锈钢管、钛管、高铬铸铁管、玻璃钢管、化工陶瓷管、有机材料衬管等,是一种理想的耐磨管道。

一、 直管与弯管通常采用柔性管接头、法兰或直接焊接连接。
二、 如采用法兰连接,为了现场安装和调整方便,凡直管管路始末两个法兰或弯管连接法兰我公司均不焊接。
三、 如客户需要的弯管规格与规格表所列规格不同,客户只要给定通径DN,弯曲半径R,弯曲角度α以及进出口加长尺寸数据,我公司就能根据客户要求生产出各种非标弯管和弯头。
四、 我公司还生产等径或异径三通、四通和多通等陶瓷钢管的管件。建湖远达。
五、 鉴于热轧钢管直线度和椭圆度均较大,随着陶瓷复合管加长,陶瓷层厚度要在长度方向不均匀性明显增加,复合管整体质量变差。复合管通常长度为3米或3米以内时,在长度方向上陶瓷层厚度均匀一致。如需要超过3米的复合管,本公司采用焊接加长,其最大出厂长度达9米。
六、 装卸时,严禁用铁钩、铁棒伸进陶瓷钢管内撞击或撬抬。

High Chromium Cast Iron Bimetal Cladding Pipe

High Chromium Cast Iron Bimetal Cladding Pipe, High Chromium Cast Iron pipe, Bimetal Cladding Pipe We are manufacturer of High Chromium Cast Iron Bimetal Cladding Pipe and supply high quality High Chromium Cast Iron Bimetal Cladding Pipe in both large and small quantities worldwide and offer you the best prices in the market. These Steel-high chromium cast iron bimetal cladding pipe is a new type of abrasion proof piping developed by our company. Outer of straight pipe is common steel pepe, cladding realized by forming high chromium lining via centrifugal forming technique. Outer of bend uses hot-bending bend and lining is cast with high-chromium cast iron. Compared with traditional wear-resistant alloy cast iron, wear-resistant alloy cast steel, general cladding steel pipe and cast stone pipe. 1. Good wear-resistance, giving full play to wear-resistance of high chromium cast iron. 2. Withstanding high pressure: It can be used for any pressure rating. Close bonding of outer and lining ...

Properties of the Ceramic-lined Steel Composite Pipes

Ceramic (Corundum: a-Al2O3) lined abrasion resistant straight pipe and fittings are lined with highly abrasion resistant ceramic by SHS -------Self-propagating High-temperature Synthetic process. Ceramic-lined Steel Composite Pipes Physical Properties Microstructure of ceramic layer Section of the composite pipe Mechanical Propertie: Hoop Strength: Hoop strength is the resistance against radial pressure. The strength of the ceramic -lined steel composite pipe is 300 to 500MPa. Compression-Shear Strength: Compression-shear strength is the bonding strength at the interface between the ceramic layer and the steel pipe. The compression-shear strength of the ceramic-lined composite pipe is 15 to 20MPa. Resistance to Mechanical Shock The ceramic layer does not crack or flake off when the composite pipe receives a mechanical shock. Resistance to Thermal Shock The ceramic layer does not crack or flake off when heated to 800℃ and then quenched. Resistance to Abrasion: The ceramic-lined steel co...

Carbon steel pipe conveying medium and can prolong the service life of ceramic lining

Carbon steel pipe material is widely used in various industries such as petroleum, chemical, mechanical, metallurgy, food and so on. Carbon steel pipe can withstand high pressure, can resist high temperature, used for transporting steam, compressed air, inert gas body, gas, natural gas, hydrogen, oxygen, acetylene, ammonia, liquid ammonia, water, oil and other media. Since the carbon steel has a certain corrosion resistance, so carbon steel pipe can be used to transport at room temperature alkali solution and corrosion medium "after heat treatment to eliminate welding stress force, carbon steel pipe can also be used to transport the caustic]. The carbon steel pipe can also be used for conveying other corrosive media, such as the lining of the corrosion resistant coating, or the corrosion resistant material lining, such as lead and rubber. 2 low alloy steel tube Low alloy steel pipe is generally made of pearlite heat resistant steel, which is characterized by high strength and heat...
