耐磨管的改造分为4个阶段

近些年电厂、钢铁、冶金、煤炭、矿山、水泥、石化等的新建和技改项目在设计时已非常注重这一点,对有关管道的耐磨性提出了较高的要求,目的在于延长管道寿命,保证电厂、钢铁、冶金、煤炭、矿山、水泥、石化等安全运行、并降低生产成本。目前建湖县远达特种材料有限公司生产的陶瓷内衬复合钢管已成为耐磨管的首选产品。

耐磨管改革阶段说明

  1. 人们在传统的普通碳素钢管的基础上,努力研制各种耐磨管道。作为第一代耐磨管道,虽改善了管道的耐磨性并提高了管道的寿命,但由于增加了负荷,提高了管道的工程造价,且当管系应力变化时铸石难以不被破坏,在电厂铸石钢管焊裂的现象时常发生。
  2. 为此,产生了第二代耐磨管道—耐磨白口铁管道,这种管道的整体性能虽优于铸石钢管,但由于其硬脆性和不可焊接性给工程施工、安装和生产维修带来了难以避免的困难和事故。
  3. 接着又产生了耐磨铸钢管道,但其存在铸造方面目前难以克服的铸造缺陷,以及技术条件要求的不完善,20多毫米厚的铸钢弯头经风压试验出现泄漏以及试用时漏粉等现象时有发生,且工程造价过高。
  4. 一种借助于工业标准批量生产的钢管作为母材、采用铝热离心工艺生产的陶瓷复合管及管件产品,作为新一代耐磨管道便应运而生。

To help you understand the main features of the wear-resistant composite ceramic pipe

The pipeline is a product that has been developed in recent years. This product has received attention from all aspects. It has a unique advantage of its own. It has been firmly established. Wear self propagating ceramic composite pipe is adopted self propagating ceramic composite pipe aluminum material by centrifugation, heat spreading sintering, because of its good abrasion resistance, water resistance, good corrosion resistance and become one of the many projects in the pipeline wear preferred products, self propagating ceramic composite pipe is easy to break and fall but the manufacturing process the traditional production, and the existence of micro crack, has certain influence on the wear resistance of the process, using the international advanced technology of nano materials, add special additives in traditional ingredients, and the sintering temperature to 2800 DEG C (pressurized aeration technology), SHS products, high strength, small micro crack good toughness, not easy to fa...

Ceramic lined pipe expansion joints

Ceramic lined pipe expansion joints are designed to safely absorb the dimensional changes of pipework systems and ducts caused by heat induced expansion and contraction. They are essential in pipework systems that are used to convey substances of a high temperature, such as steam, heated water or exhaust gases. Expansion joints can also be designed for other applications, such as noise and vibration caused by reciprocating machinery, building settlement and in some extreme environments earthquake movement. Expansion joints are very important components with in a pipework system as they not only solve the problems associated with pipework movement but offer such advantages as reducing stresses and loads to connecting equipment such as pumps and steam turbines.

Ceramic Tile Lined Bend

Ceramic tile lined bending have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe and gives a very smooth surface. It is well understood that conveying velocity of ash, its density as well as size of ash particles are major factors that determine wear rate of Bends and Y-Pieces. Here, the use of Alumina Ceramic in Ash Handling systems help in lowering the possibility of wear and damages caused to the internals. Here, our expertise lies in filling the linings in casings manufactured at our works or can also be fitted directly in worn out volute casing at plant site. Well package of Alumina Ceramic Lined Bends Some of the industry areas where these are used include: Coal Fired Thermal Power Projects Mineral processing units Steel Plants Cement Plants Coal and Mineral washeries Aluminium plants

Alumina ceramic lined pipes

Ceramic Tile Lined Steel Pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe and gives a very smooth surface. Ceramics with very low friction factor at low impingement angles decreases the abrasion of materials maximally. Its low density makes it easy to carry and install. Furthermore, its diamond-like hardness, fine grain structure and superior mechanical strength are the unique features that make it a wide range of demanding applications, such as coal preparation, power generation, iron and steel making, cement, asphalt, dredging, mining and mineral processing, oil and gas drilling. The Ceramic Tiles could protect Industrial Components against abrasion, impact wear and high temperature of above 1000C. Standard Flat Tiles of Square & Rectangular Shape having thickness of 6 to 50 mm, with or without central hole are available.
