Anti Wet Fully Threaded Studs

Stud Bar ASTM A320 Grade L7 L7M L43 "End to End" Class 2A



1, Not sticky: Almost all the material is not bonded with PTFE coating. Thin film also showed good adhesion properties.
2, Heat resistance: PTFE coating has excellent heat resistance and low temperature properties. Short period of time can be high temperature to 300 ℃, generally between 240 ℃ ~ 260 ℃ can be used continuously, with significant thermal stability, it can work without embrittlement in freezing temperatures, it does not melt at high temperatures.
3, Sliding: PTFE coating has a low coefficient of friction. Load sliding friction coefficient changes, but only in the values ​​between 0.05-0.15.
4, anti-wet: PTFE coating surface water and oil production operations are not easy to dip solution, such as sticking a small amount of dirt, simply wipe clean. Downtime is short, save time and improve efficiency.
5, Wear resistance: under high load, with excellent wear resistance. In a certain load, wear-resistant and non-adherence with the dual advantages.
6, Corrosion resistance: PTFE is almost free from erosion of the drug, in addition to withstand molten alkali metal fluoride, a strong acid medium, and above all than 300 ℃ sodium hydroxide (including aqua regia), strong oxidizing agents, reducing agent and various organic solvents, can protect parts from being any kind of chemical corrosion.
