Detailed Product Description

insulated joints:

The overall role of joint-type insulation

     Buried Steel oil, gas and water pipes due to corrosion and damage, not only reduces life expectancy, but also cause serious accidents. Buried pipelines to prevent corrosion is to take effective measures to cathodic protection technology. Cathodic protection in the project, asked to be connected with the protection of pipelines and certain devices, equipment, cut off the electrical connection between the slip road to avoid the negative-level current loss protection does not require the protection of the connected components. Cathodic protection technology to ensure success.

     Used previously to achieve this insulation flange separated electric connections. However, the construction site to install insulating flange require clean, non-humid, this is hard to meet. Insulation flange bolts are often unreliable. Has been shown that many insulating flange insulation to ensure that only short-term. Flange due to insulation failure, often painstaking planning and construction of the cathodic protection system failure, resulting in leakage or leakage, resulting very high maintenance costs. In addition, the buried insulating flange often require ancillary structures - flange Well, the number of surface covering and additional costs.

     Pipe insulation installed in the new power - the whole advent of joint-type insulation, it has overcome these problems. It uses a maintenance-free, non-removable structure as a whole, can be directly buried without ancillary buildings, the use of extremely simple and with high reliability.

     This type of total joint insulation can meet the requirements of cathodic protection and to avoid the existence of the insulating flange of the defects, as a new-generation products has a wide range of used abroad. SY/T0086-2003 China has promulgated standards, also recommended the use of this new product.

 The characteristics of products ZJ3

     Insulation joints ZJ3 whole generations of scientific and technical personnel through the company's tireless efforts to develop, has formed a series of products. In product design, material properties, tooling and process improvements in areas such as unique, with all their own intellectual property rights. Product quality and abroad can be comparable to similar products. By national ministries as five state-level key new products.
