What is saddle fusion? Saddle fusion (sidewall fuson) is, like butt fusion and socket fusion, another process based on hot plate welding. Saddle heat fusion differs from either socket, or butt fusion methods by performing fusion into the side of the pipe wall in a transverse orientation to the main pipe, rather than in line with the pipe. Hdpe saddle welding required workshop saddle fusion machines. This hdpe fusing process can be conducted while pressurized creating a [hot tap" when allowed by regulations and the pipeline owner. The pipe and saddle fitting surfaces are heated/fusing until they reach a proper temperature, the heating tool is removed and then the weld is formed. The process is complete following a cooling process. Always have a trained joining operator perform this procedure using properly maintained Pipe Fabrication Workshop Machines.

Electric fixed ball valve working principle and classification
Electric fixed ball valve in the pipeline is mainly used to cut off, distribute and change the direction of medium flow. Electric fixed ball valve in the design of the pivot structure, the design features to ensure the exact location of the ball. Spring structure with the valve seat, the valve cover to the ball, the effect of low pressure sealing far surpass similar valve products. Electric fixed ball valve pivot blow protection structure with a low friction coefficient of the bearing. With excellent performance, high reliability, wide range of uses, the price is reasonable and so on. According to its section is divided into two parts and three types of two fixed ball valve. Electric fixed ball valve for: chemical, petroleum, natural gas, metallurgy, and other industries and containing hydrogen sulfide medium, impurities, serious corrosion of natural gas long-distance pipeline.
