Product Features

Oxygen flame arresters are widely used in oxygen transport pipelines in industries such as metallurgy and chemical engineering. They 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 4MPa. There are two connection methods: flange and welding.

FP-XT type oxygen flame arrester and FPV-XT type oxygen flame arrester are respectively used in front of and behind the valve, and 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.

Installation And Maintenance
In order to ensure the safe use of flame arresters, they should be regularly inspected and maintained.
1. The flame arrester should be inspected every six months to check whether the flame arrester core is blocked, deformed, corroded, etc.
2. The blocked flame retardant core should be cleaned thoroughly to ensure that each hole on the core is unobstructed. The deformed and corroded flame retardant layer should be replaced. 3. When reinstalling the fire-resistant layer core, it should be ensured that the joint surface is tight and there is no air leakage.

Ordering Instructions

When placing an order, the following parameters must be determined: ① caliber; ② Work pressure; ③ Material; ④ Flange standard; ⑤ Medium; ⑥ Operating pressure; In order to provide you with suitable products.
