The oily PTFE tape should be cut off before construction to avoid confusion and various problems at the construction site. Let's discuss the pre-pressurization technique for everyone.  

When cutting, its length and width direction should be slightly larger than the size of the soft belt guide on the design drawing to prevent slipping during the bonding process. From this point of view, a unilateral enlargement of 2-5mm is sufficient. However, if bonding is considered, the soft band needs to be tightened from both ends (in the long direction). In the long direction, it is proposed to place a length of 20-40mm on one side. 

If the soft belt is not long enough, it can be spliced, flat end butt, V-shaped butt convex triangle or beveled edge butt, and the width direction can be arranged in rows.  

Nowadays, PTFE tape is used on pipes, so how do you test the product after sealing?  

Its sealing performance is very good, and it is relatively convenient to use. It is more widely used for pipe sealing. 

How to identify water leaks when checking water pipe connections:

Once installed, we will wipe the joint, wipe it clean, then put some toilet paper on it, remove it after a while and check its dryness. Toilet paper. If the toilet paper is not wet, it can be used with confidence. If something else happens, you have to deal with it or reinstall it in a timely manner.
