Polytetrafluoroethylene (Teflon) is generally callednon-stick coatingoreasy-to-clean material. This kind of material has the characteristics of acid resistance, alkali resistance and resistance to various organic solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance. Its friction coefficient is very low, so it can both be applied as lubrication and become an ideal coating for easy cleaning of inner layer of water pipe. PTFE tape includes PTFE wraping film, PTFE wraping tape, PTFE sealing tape, etc.



1. PTFE Degreasing Tape Can Be Applied in Gas Joint

Polytetrafluoroethylene is the polymer material with the most stable chemical properties among the known materials, which can resist the corrosion of most chemical substances and can completely resist the chemical corrosion of coal gas. Moreover, due to its good creep properties, polytetrafluoroethylene can timely fill the gap of joints and is the best joint sealing material.

When gas pipes and their accessories to furnaces, grills or other connectors are connected, be sure to apply teflon tape designed for gas connectors instead of teflon tape designed for water pipes. Polytetrafluoroethylene tape seals the thread of gas fittings to prevent gas leakage. Polytetrafluoroethylene tape for gas accessories can be purchased in hardware, home decoration and pipeline supply stores.


Apply teflon tape for gas only on the thread of fittings. Do not stick the tape on the gas compression joint, that is, the detachable nut and bolt used to connect two gas pipes. Fittings are not removable when they are located at the end of the gas line. Before gas pipes are disconnected or connected to electrical appliances, all gas connections of gas meters at home or outside the company should be closed.



2. The Difference between Special PTFE Tape for Gas Pipeline and Liquid Sealing Belt

(1) Sealing Performance of Liquid Sealing Belt on Gas Pipeline

Liquid sealing belt has the best sealing performance for metal materials. The sealing performance of this kind of sealing belt is excited by metal ions. Therefore, it can only be applied in the sealing of metal materials, not in the sealing of other materials. The liquid sealing belt will form solid plastic in the metal pipe. This plastic has elasticity and its anti-aging performance is very strong. It can not age within 50 years and has very good performance.


The performance of liquid sealing belt is not only good, but also the method of application is very convenient. There is no need to wind and tighten. Just apply a few drops on the metal thread and tighten the screw. And the angle of the pipe can be adjusted at will before the sealing belt solidifies.

(2) Special PTFE Tape for Gas Pipeline

The special PTFE tape for gas pipeline is a kind of auxiliary equipment commonly applied in the installation of water heating natural gas. It is applied at the joint of pipe fittings to enhance the tightness of pipe joints. The chemical name of special PTFE tape for gas pipeline is polytetrafluoroethylene. At present, ordinary white polytetrafluoroethylene belt is applied in HVAC and water supply and drainage, and there are special polytetrafluoroethylene belts for natural gas pipeline. In fact, the main raw material is polytetrafluoroethylene, and it is just that some processes are different. PTFE tape includes gas PTFE tape, PTFE thread seal tape, waterproof PTFE thread seal tape, etc.


The special PTFE tape for gas pipeline is a new energy-saving and green ideal sealing material. It is produced with imported materials and advanced technology, with excellent quality and complete specifications. It can meet the requirements of different customers in different industries. Because of its non-toxic, tasteless, excellent tightness, insulation, corrosion resistance and strong stability, it is widely applied in machinery, metallurgy, electric power, ship, electronics, water treatment, natural gas, plastics, electronic engineering and other fields.




For the sake of safety, special plumbers or maintenance personnel can also be invited to complete the installation or maintenance of the pipeline during installation and maintenance. PTFE tape also includes PTFE thread sealing cord, expanded PTFE film, pipe sealant PTFE tape, PTFE thread seal tape, etc.
