Custom-made Ptfe Gland Packing | Ptfe Gland Packing Producer

White colour，don’t shed color or dross,Therefore, it can be used in chemical industry, food, medicine, papermaking, chemical fiber, fine chemical industry and other operating occasions that do not allow pollution. It is suitable for all chemical media except soluble alkali metals and free fluorine ions.

Use a cutting machine to accurately cut the gland packing of the required length. If there is no packing cutting machine, then cut according to the length of the ramie packing L=(shaft diameter d+packing width s)X1.07X. Generally, on the rotating shaft, Use a 90° straight cut and a 45° cut on the valve. Then cut it into a sample ring and verify that it fills the space correctly and that there are no voids at the interface. The sample ring can then be used as a standard to cut other packing rings. Install packing rings one at a time, making sure each packing is free of dirt or other debris. Install each packing ring staggered at 90°. The rings are pulled apart slowly in the axial direction, and the radial distance is enough to allow the rings to be installed on the shaft. Use professional packing tools to tighten each packing ring. When enough packing rings have been installed, the glands extend to 25% of the packing thickness of the stuffing box for valves and 50% of the packing thickness for pumps. Close it with a follower, which can be used to increase the tightness.

The following are the main characteristics of black PTFE gland packing:

Chemical resistance: PTFE has excellent resistance to chemicals, acids, and alkalis, making it ideal for use in harsh chemical environments.

Temperature resistance: Black PTFE gland packing can withstand high temperatures, up to 260°C (500°F).

Low friction: PTFE has a low coefficient of friction, making it a good choice for applications where reduced friction and wear are important.

Durability: Black PTFE gland packing is strong and durable, providing long-lasting performance in demanding applications.

Non-toxic: PTFE is a non-toxic material, making it safe for use in food, pharmaceutical, and medical applications.

Non-stick: The non-stick nature of PTFE helps to prevent buildup and adhesion of substances, making it easier to clean and maintain.

Ptfe gland packing is used for valves and rotary pumps with anti-fouling requirements, weak alkali and strong acid fluids. According to the corrosive environment and user needs, the packing (packing) can also be treated with corrosion inhibitors to make the packing (packing) root) more durable and good anti-corrosion function.
