FP series oxygen pipeline flame arrester
summary:
The FP-XT oxygen pipeline flame arrester and the FPV-XT oxygen pipeline valve front and rear flame arresters are welded with special copper alloy and stainless steel. It can effectively prevent the "adiabatic compression" that is easily formed when the oxygen pipeline valve suddenly opens, causing a sudden rise in local temperature and becoming a source of ignition energy; It can prevent high-speed moving particles (such as rust, dust, welding slag, etc.) from rubbing and colliding with the pipeline behind the valve under the pressure difference before and after the valve, generating sparks and becoming ignition energy. The use of flame arresters can quickly block the source of fire and prevent the occurrence of combustion accidents in pipelines.
Purpose:
This product is widely used in oxygen transportation pipelines in industries such as metallurgy and chemical engineering. It can effectively cut off the fire source caused by the rapid friction between debris and pipe walls in high-speed airflow, and prevent pipeline explosion accidents from occurring. Users can directly weld and connect this product to the appropriate part of the oxygen pipeline for operation. This flame arrester is suitable for use as a flame arrester in oxygen pipelines with a diameter of DN15-500mm and a working pressure not exceeding 3MPa.There are flange and internal thread connections.

Note: 1. Pipeline nominal pressure PN=4MPa
2. Please specify the material and specifications of the oxygen pipeline when placing an order, so that suitable connecting materials can be selected.
3. According to user needs, flame arresters can adopt flange structures, and the flanges are designed according to JB/T82.2-94 standards.
