TAPERED PIPE THREADS AND FITTINGS: MAKING THE CONNECTION

Before installing gas or liquid tight connection, it is crucial to understand what tapered pipe threats are and how they work. Difference between tube and pipe: Yes they are not same. Pipe and tubes have a hollow structure and are typically designed to provide a track for fluids and gases to pass through.  The significant difference between the pipe and tube is that pipe walls are much stiffer and thicker making them stronger than tube walls. Tubing walls are not meant to be threaded because they are too thin to provide a firm hold. Pipe walls being thicker and stiffer can be easily used to mould and cut threads and also give a high support. Threaded pipes are sufficient to provide tight connections to liquid and gas flow that are also mechanically strong. Let’s understand the mechanism of pipe threads. When the pipe fittings are weak, or of a low standard, they can result in breakage or leakage increasing the production expenses. Fittings that are effective and

DIFFERENCE BETWEEN ROLLING THREAD AND CUT THREAD PIPES

First comes, the differences in their processes. Cut threading simply removes material from the round bar of steel to form threads while roll threading takes place with the help of a hardened steel die between the diameters of the finished thread. This causes the formed thread roots outwards to create the crests. One of the most important things is the cost of the thread pipe nipples as well. The way steel is processed during cut threading, takes longer labor times which adds to its costs. Cut threaded bolts are not suitable for manufacturers of sensitive equipment as there are quite a few limitation with regards to diameter and thread length with cut threaded bolts. On the other hand, rolling thread pipe nipples and bolts require much shorter labor times, which means that they are a slightly more affordable option. The rolling thread process also strengthens the bolts in three ways. This includes tension, fatigue and shear resistance. Rolled thread bolts also have
