To this end, a study aimed at investigating the behavior of T joints reinforced with FRP t pipe fitting has been performed under compressive axial load to evaluate the efficiency of these materials in improving these joints.
How to join t pipe fitting together?
There are several types of plastic plumbing used in residential plumbing, but PVC has become the industry standard for drain pipes and valve lines. PVC pipes are very popular because they are very easy to cut and move and because they are much cheaper than other options. In older homes, the main drain pipes and vents were often made of cast iron, an expensive material that was very difficult to work with. For this reason, upgrades to old pipe discharge systems are almost always made of PVC pipe.
PVC stands for Polyvinyl Chloride, a synthetic plastic that has excellent stability and stress tolerance. It is also approved for draining pipes for water supply pipes and is therefore often found in outdoor irrigation systems. However, it does not tolerate high temperatures and therefore is not used for indoor water supply systems.
The process of putting PVC together makes the older materials used in pipe fittings easier. Pipes can be cut with an ordinary saw, and a variety of comfortable unions, tripods and other accessories are available for assembling the system.
T-pipe connection is one of the most up-to-date and common connections, which has the advantage over other connections having a high resistance of the connection against the pressures. T-pipe is used for branches that have high sensitivity and the pressure on the connection is high, and also in branches that have high pipe size and high sensitivity project. The reason for the high resistance and strength of the T-pipe connection can be considered in the fitting method and its fixation completely on the pipe and the welding steps above this type of connection. Has been. The assembly operation of this connection is done in two steps. The first stage is assembled inside the connection production workshop and the final stage is performed on the main pipe at the project site.
Method of fabrication and assembly of T-tube:
As mentioned above, the initial assembly of the T-pipe connection is done inside the workshop. First, the pipe is cut to the desired length and size with high accuracy, then it is divided into two parts in the longitudinal direction. It should be noted that all pipe cutting operations are performed with an air cutting machine. After cutting the pipe,t pipe fitting pvc، all the cut edges of this piece of split te are carefully angled and prepared for welding operations. The two separate parts of the tube are called the top and bottom of the connection pad
Domestic demand for t pipe fitting in 2020
After the successive increases and the game with the supply of PVC, the association made many actions and correspondences with the managers of the relevant institutions.
According to this report, in the last letter of the association addressed to Molakhah, the director of chemical and non-metallic industries of the Consumer Protection Organization, in order to prevent further weakening and closure of standard production units and unemployment of a large part of the labor force, to agree to Increase the price of these commodities based on the relevant impact factors,t pipe exhaust، or rapid management of the stock market and returns…
