What is the pipe fiber?
Hrut fiber is a spiral comb at the end of the pipe that allows the pipeline to be connected. For male fittings, this fiber appears on the outer diameter of the pipeline; If she is a woman, she appears on the inner diameter. By turning the male tube to the end of the female thread, it connects to both.
As the fibers of men and women must be successfully aligned to create a connection, they adhere to industry standards. Two main standards are National Pipe Thread (NPT) and National Standard Freely Fitting Direct Mechanical Pipe (NPSM) . NPT is a tapering thread that can create a wet seal. NPSM is straight and forms only mechanical seals; It is not used for liquid applications. In the United States, garden hoses have their own standard (GHT), as well as fire hoses that use the national standard fiber (NST).
When accessing NPT cone -shaped Thread piping to create a seal of durableAgainst leakage, professionals recommend using a seal such as a tape Polytrafluorethylene (PTFE). PTFE, more often known as Teflon®, is also the name of the most famous brands of sealing tape. The tape should be wound firmly around the male threads and ran in the same direction as the lead fiber, so that the pipeline connecting movement monitors the direction of the belt winding. The sealing tape makes it easier to ride the male pipeline by slipping the fibers, while filling small gaps to prevent leakage. The pipeline tape also facilitates the discusing of the joint later, if necessary, by reducing galling or tendencies of some types of fibers to hold together over time.
Modern pipe sizes are determined by measuring the outer diameter (from), which are measured above the pipe threads in the case of the male pipeline. If you want to make sure the fibers will respond, you can also calculate the thumb (TPI). Inner Diameter (ID) is sometimes used when buying polyvinyl chloride or pvC, pipes.
Building regulations require the pipe to meet certain standards depending on the application. The various materials will be made for pressure gas or liquid, natural gas, drinking water and underground drainage pipes. Note that local laws may require only licensed suppliers to work on gas management. Before implementing any project of the domestic pipeline, check the local building regulations and take the right safety measures.
