1. Product introduction of the Steel lined F4 tee
Our Steel lined F4 tee serves as a critical fitting for fluid diversion or merging in chemical piping systems. It features a carbon steel outer shell lined with polytetrafluoroethylene (F4) composite.
By leveraging the near-perfect corrosion resistance of F4 material, this tee resists most harsh media, including strong acids, bases, organic solvents, and even aqua regia. As a result, it ensures excellent corrosion resistance even in complex flow paths.
2. Product advantages and functions of the Steel lined F4 tee
Firstly, our Steel lined F4 tee diverts fluid flow into two branch lines in different directions or combines two fluid lines into a main flow, making it ideal for applications such as reactor feed distribution or sampling line connection.
In addition, the tee provides the mechanical strength of steel, allowing it to withstand pipeline pressure safely. Moreover, its smooth, corrosion-resistant F4 lining reduces fluid resistance, prevents scaling and clogging, and eliminates the risk of leaks caused by fluid erosion or corrosion in traditional tee dead ends.
