Do you know pipe thread sealant?

The pipe thread sealant is a one-component sealant made of the principle of free radical inhibition by oxygen, which can be used for both bonding and sealing. When the glued surface is isolated from the air and catalyzed, it can quickly polymerize and cure at room temperature. In the pipeline construction process, there are many factors to consider when choosing the best pipe thread sealant.

 

 

Application of thread sealant

Teflon thread sealants are widely used in the installation of piping systems. For example, such as natural gas pipelines, compressed air pipelines or indoor tap water pipelines. The most common threaded pipe is NPT thread. When the NPT thread is cut, the internal thread and the external thread are tapered, so that it is easy to align the external thread during the joint assembly. In the process of connecting pipes, it is impossible to achieve a watertight/airtight seal simply by tightening in this way. In the actual construction process, a suitable water pipe sealant should be selected to fill the gap at the root of the thread to achieve sealing.

Selection of thread sealant

There are two forms of thread sealant, Thread Seal Tape or pipe joint compound (commonly referred to as "pipe paint"). These two sealants have their own advantages and disadvantages, we can choose the appropriate thread sealant according to the specific pipeline.

 

Selection of best thread seal tape

Pipe thread tapes are available in a variety of widths, thicknesses, densities and colors.

 

The width of the Ptfe Thread Seal Tape includes ½ inch, ¾ inch and 1 inch. The main basis for the selection of the width is based on the diameter of the pipe. For smaller diameter pipes, ½ inch width tape can be selected. Sealing tape with a width of 3/4 inch or 1 inch is suitable for larger diameter pipes.

 

Thickness is usually expressed in mils. A threaded sealing tape with a higher thickness can reduce the construction time and better complete the sealing work.

 

The density of the threaded sealing tape is related to the tightness of the pipe seal. The high density threads sealing tape will not be excessively stretched during the assembly process, and will not lead to the risk of leakage due to reduced tightness.

The colorful colors of the threaded sealing tape can visually mark the substance in the pipe. Some construction units are accustomed to use red thread tapes for natural gas pipelines and blue ones for water pipelines. This also brings convenience to future maintenance. What color of the sealing tape represents what pipe, it also looks pleasing to our eyes.

 

Selection of pipe joint compound

The selection of pipe joint compounds is based on the compatibility of pipes and fittings, chemical compatibility and temperature performance range.

 

Among them, whether the pipe joint compound is compatible with the pipe and fittings is very important. Improper selection can cause material degradation and malfunction.

 

When choosing which pipe joint compound to use, chemical compatibility is also an important consideration. The piping system is a system that needs to ensure long-term safe and stable work. If the pipe joint compound is incompatible with the pipe material, the chemical composition of the pipe joint compound will be damaged, causing safety hazards and accidents.
