Precautions for transportation, handling, storage and installation of wear-resistant ceramic tubes

The construction of wear-resistant pipeline engineering needs to go through many working procedures and complicated processing, so the production process is complicated and huge.Some construction process technological parameters are quite strict, also very demanding.This kind of production particularity, will bring to the safety production very big.

Transportation, handling and storage
Ceramic composite wear-resistant pipe in the process of loading and unloading, it is prohibited to throw from the height or the car to the ground.When the straight pipe is loaded and transported, the part extending out of the outside part of the vehicle body shall not exceed 1/4 of the length of the pipe.
In the process of handling and installation, the pipe fittings should be moved gently to avoid serious collision.When loading and unloading, it is strictly prohibited to use iron hook, iron bar into the wear – resistant lining ceramic tube impact or pry up.In particular, avoid direct contact with or impact on the end of the metal equipment ceramic layer.
When transporting pipe fitting, layer by layer stack must be stable and firm, not allow relative sliding and rolling impact.
When storing pipe fittings, they can be stacked layer by layer, but the height of pipe stack is not allowed to exceed 3 meters.

Installation
The construction of wear-resistant pipeline engineering needs to go through many working procedures and complicated processing, so the production process is complicated and huge.Some construction process technological parameters are quite strict, also very demanding.This kind of production particularity, will bring to the safety production very big.

Easy installation and construction, because the tube light weight, and good welding performance.
Therefore, welding, flange, fast connection and other methods can be adopted to facilitate construction and installation, and can reduce installation costs.

Wear-resistant pipeline construction and welding installation site
When the wear-resistant ceramic tube needs to be cut in the installation process, it can be cut by plasma cutting machine.It is best not to use gas cutting, if you really want to use, should increase the power, but after cutting the end is not smooth, but also easy to cause damage to the ceramic layer.
During the installation of wear-resistant ceramic pipe, the center line of the pipe and the pipe shall be aligned to ensure that the two ends meet accurately, and the dislocation of the two ends shall be controlled within 1.0mm.
When flange connection is adopted, the flange end face shall be flush with the end face of the composite pipe to ensure the reliability of the connection.
When the connection is made by welding, the groove shall be 60-90 “V” groove, with a blunt edge P of 2-4mm, and shall be welded with a small current of 80-100a without any gap.
At the same time, the bottom of the welding groove of wear-resistant ceramic pipe should be far away from the ceramic layer so that the ceramic layer can be better protected during welding.

Application scope of wear-resistant ceramic pipe
Different wear-resistant pipe installation should also pay attention to the characteristics of the lining wear-resistant material, such as some materials can not be welded, welding will damage the lining wear-resistant layer.
