1. Product introduction of the Steel lined PTFE cross
Our Steel lined PTFE cross is corrosion-resistant fittings used for multi-directional distribution or aggregation of fluids in corrosive chemical and pharmaceutical process piping.
Our Steel Lined PTFE Crosses consist of a carbon steel shell molded with PTFE (F4).
2. Product advantages and functions of the Steel lined PTFE cross
Our steel lined PTFE cross can simultaneously connect the intersections of three or four different equipment or process lines. For example, this allows for the simultaneous distribution of a feed stream to three reaction stations, or for the convergence and switching of multiple fluid paths within complex filtration or heat exchange systems.
Our steel lined PTFE cross utilizes processes such as compression molding to ensure uniform lining and seamless dead space within complex cross-flow channels. PTFE’s chemical inertness makes it corrosion-resistant to most harsh media, including strong acids, bases, and organic solvents.
The core advantage of our steel-lined PTFE cross is that it integrates complex, multi-way connections, which traditionally require multiple tees and short pipe connections, into a robust steel housing. This significantly reduces flange connections and potential leaks in the pipeline. The smooth PTFE lining also reduces fluid resistance and scaling, significantly improving overall system integrity, reliability, and ease of maintenance in corrosive environments.
