What details should be paid attention to when using flexible graphite packing
The flexible graphite packing is woven from a flexible graphite composite coil. Mainly used for static and dynamic sealing of valves, pumps and pipelines. The product has wide applicability, high temperature resistance, strong acid resistance, strong alkali, high temperature resistance, long life, self-lubrication and bottom friction coefficient.

The product has wide applicability, high temperature resistance, strong acid resistance, strong alkali, high temperature resistance, long life, self-lubrication and bottom friction coefficient. What details should we pay attention to when using flexible graphite packing? Let's take a look at the following: 1. The tools needed to replace the old flexible graphite packing with a new tool (with a root extractor) and a pre-tightening nut with a fastener. In addition, standard safety facilities and relevant safety regulations must be used frequently. Before use, first familiarize yourself with the following equipment: the cutting machine for verifying the flexible graphite packing ring, the calibration torque wrench or wrench, the helmet, the internal and external calipers, the lubricant of the fastener, the mirror, the packing extractor, the packing Cutter, vernier caliper, etc. 2. Cleaning and inspection 1) Slowly loosen the fixing nut of the stuffing box to release all residual pressure in the flexible graphite packing assembly; 2) Remove all old flexible graphite packing and thoroughly clean the packing box of the shaft/rod; 3 Check the shaft/rod for corrosion, dents, scratches or excessive wear; 4) Check other parts for burrs, cracks, and wear, which will reduce the life of the sealing packing; 5) Replace parts with large defects 6) Examine the old flexible graphite packing as a basis for failure analysis to find the cause of early failure of the flexible graphite packing. The above is the details that need to be paid attention to when using flexible graphite packing. I hope that we can do these details when using. Http://news.chinawj.com.cn
