Binding force:
That is, the tightness of the combination of the inner and outer pipes is the most important detection indicator of the bimetallic composite pipe.
The CJ/T192-2017 standard of the Ministry of Urban Construction and the SY/T6623 standard of China National Petroleum Corporation stipulate that the minimum value is 0.2Mpa and 0.5Mpa. The products produced by Jiangsu Zhongxin can reach 0.8-1.6Mpa, and the products of most enterprises are maintained at 0.5Mpa.
The cost-effective advantage of bimetallic composite pipe compared to pure alloy pipe:
The higher the price of the alloy, the greater the cost savings of using bimetallic clad pipes.
