Seamless hot pressing elbow knowledge explanation

Elbow and elbow are common special-shaped pipe parts in pipeline construction. These two kinds of pipe parts play a very important role in the construction. It is because of this that a large number of pipe parts are often purchased during construction

Elbow is a kind of pipe fitting used at the bend of the pipeline. Hot pushing, die casting, extrusion and other steps are commonly used to finalize the seamless elbow.

Do you know some knowledge and storage method about seamless hot pressing elbow? Then we will follow Maitred Pipe fitting manufacturer to learn about it

Manufacturing process of seamless hot pressing elbow

The seamless hot-pressing elbow is heated to the corresponding temperature, and after holding for a while, it is refrigerated slowly, which is called cooling. The elbow component is heated according to the phase transition or the temperature transformation of the phase, and the cooling heat treatment process method is maintained.

The significance of cooling is to clear the defects of the elbow, improve the elbow fittings, symmetry and optimization of the crystal, improve the mechanical system characteristics of the hot pressing elbow, reduce the residual stress, but also can improve the plasticity and toughness, reduce hardness, improve the computational cutting technology characteristics.

Therefore, it is not only used to remove cooling and improve the previous left-down process of defects and residual stress of pipe fittings, but also used to prepare the following process. Therefore, it belongs to the semi-finished heat treatment process, also known as preheating treatment.

Storage of elbows in pipe fittings

The exposed machined surface should be kept clean and dirt should be removed. It is necessary to check on time and not be exposed outdoors for a long time. If it is necessary to be exposed, it is necessary to maintain clean in time and then remove stains

To put the seamless hot-pressing elbow in a dry ventilated place for storage and cleaning the house, the stamping elbow can not be piled up and stored in the open air, because the seamless hot-pressing elbow should be maintained dry and ventilated, so it needs to be stored in the correct storage method

Seamless hot pressing elbow operation mode

Before operation, be sure to carefully check the standard and diameter of seamless hot-pressing elbow, clean the dirt of seamless hot-pressing elbow, and remove the shortage caused by transportation. When everything is ready, stainless steel elbows are produced by hand wheel. It is not recommended to use levers or other tools to avoid damaging valve components. Turn the hand wheel clockwise to turn it off. In turn, when opening the handwheel, it should be used reasonably to ensure proper use and installation.

Installation, stainless steel pipe elbow can be directly installed on the pipe according to the connection mode, generally can be installed in any position of the pipe, but easy to operate and maintain. Note that the medium in the elbow should flow under the longitudinal disc and can only be installed horizontally. When installing, attention should be paid to sealing. Prevent leakage, affect the normal operation of the pipeline
