Gauge tube bend
Thread Content
The forum has seen many discussions about the use of bends in pressure gauge pipes; it is said that bends are necessary when the temperature exceeds 60 degrees Celsius. My asphalt delivery pipes are exposed to temperatures of 200 degrees Celsius. What should be done if the asphalt cools down inside those bends? Please offer some suggestions. There are no relevant posts on the forum, only some posts discussing the function of bends
It is recommended not to use elbow pipes for asphalt, as they tend to get clogged. We use diaphragm pressure gauges.
It is recommended to cover the bending area of the elbow pipe with insulation material
There are non-flowing dead ends; it’s better to use a diaphragm pressure gauge on the upper floor
To measure the pressure of high-temperature asphalt, diaphragm pressure gauges are generally used. There is a radiator between the gauge head and the diaphragm body in such gauges, so a gauge bend is not required
