Internal thread flame arrestor Fire resistance arrester

The internal thread pipe flame arrester refers to a safety device installed on the flammable gas channel, made of stainless steel, used to prevent the flame spread of flammable gas and liquid and prevent the explosion caused by tempering.

It is usually installed on storage tanks and pipelines that transport or discharge flammable and explosive gases. (The function is to prevent external flames from entering the equipment and pipelines containing flammable and explosive gases or to prevent the flame from spreading between the equipment and pipelines.fire arrestor The flame arrester is designed and manufactured based on the principle that when the flame passes through the narrow pores of the thermal conductor, it is extinguished due to heat loss. The fire retardant layer structure of the flame arrester is gravel type, metal wire mesh type or corrugated type.

The flame arrester is usually installed on the fuel gas main line in front of the furnace, which is usually a short tube with a diameter thicker than the fuel gas pipeline and a flange at both ends. Anti-detonation type flame arrester inline Ten pieces of copper wire mesh are installed vertically in the tube and the air flow. Generally, cast aluminum rings of a certain thickness are used to press the periphery of the mesh and form a certain interval. Due to the excellent heat dissipation performance of the copper mesh, when the flame encounters the copper mesh, the temperature drops sharply and the flame is extinguished, thus playing the role of fire resistance.

Product characteristics of internal thread pipe arrester

1: The burning resistance is qualified, the burning resistance test is 1 hour without tempering phenomenon.

2: Qualified explosion resistance, flame arrester 13 consecutive subsonic flame tests, each time can prevent the passage of the flame.

3: The shell water pressure test is qualified, and the water pressure test is 2.4MPa without leakage. Reasonable structure, light weight, corrosion resistance.

4: The flame arrester core is made of stainless steel, corrosion resistant and easy to clean.

With the string on her ass, she ran away. Asako and old wood look back to normal, old wood said: "or small six, not others impersonate." Pockmark pat chest, said finally rest assured. Xiao six yawned and said to Ma Zi, "Go and close the door, don't see the patient today, I'll sleep for a while, call me when the duck soup is ready." Asako wanted to say that I came to feed it, but think about the scene of feeding medicine just now, and think about it, that is really more fine than embroidery, he really can't do it. When the duck soup was stewed, Asako knocked on Xiao Six's door, and Xiao Six came out and entered the man's room. Like feeding medicine just now, it took more than half an hour to let the man drink half a bowl of duck ground soup. When the man rested for half an hour, Xiao Six put the ointment on his hands and prepared to knead the acupuncture point for the man, "You, that was... It's been a long time, and some muscles have atrophied, which is painful, but it's stimulating and it helps with recovery." The man closed his eyes and nodded his head slightly.
