Oxygen flame arresting

Oxygen flame arresting


Description

Oxygen pipe flame arresting and valve front oxygen flame arresting and Post-valve oxygen flame arresting are welded with special copper alloy and stainless steel. It can effectively prevent the "adiabatic compression" which is easy to form when the oxygen pipeline valve is suddenly opened, the local temperature rises rapidly and becomes the ignition energy; It can be prevented under the action of the pressure difference between the front and the back of the valve, the particles of high-speed movement (such as rust, dust, welding slag and etc.)  rubs against the pipe behind the valve and impact produces spark to become the ignition energy. The oxygen flame arresting can quickly block the supply of goods and prevent the occurrence of explosions in the pipeline. It is widely used in oxygen transportation pipelines of metallurgy, chemical industry, etc. Customers can directly run this product by welding and connecting the appropriate part of the oxygen pipeline.

Features

The oxygen flame arresting has a reasonable structure, light weight and corrosion resistance. Easy to overhaul, easy to install, qualified for detonation, and qualified for water pressure test of the shell.

Maintenance and use

The pipe of installing the oxygen flame arresting must be clean, free from impurities, dirt and other things that affect the normal use of the flame arresting. Oxygen flame arresting is generally installed horizontally or vertically; the site can be directly installed on the required pipeline according to the connection method; when cleaning the oxygen core member, it should be purged with high pressure steam, non-corrosive solvent or Compressed air, and should not be sharp hardware scrubbing.

In order to ensure the performance of the oxygen flame arresting for safe use, the flame arresting should be regularly inspected and maintained. The oxygen flame arresting is inspected every six months to check whether there is any deformation or gap in the copper section of the oxygen pipeline flame arresting. If similar problems occur, the oxygen flame arresting should be replaced in time to ensure the safety of the oxygen pipeline gas transmission.

When re-installing the oxygen flame arresting, the seal of the flame arresting and the pipeline should be ensured, and no air leakage should be allowed.
